10.1 LOW PRESSURE ALARM MANAGEMENT

The low pressure alarm reset is automatic.It gets manual if the alarm occurs for the number of times set by the following parameter within one hour:

par 69 hourly LP max. alarms 5The low pressure alarm is temporarily disabled when the compressor starts in order to allow settlement of pressure.The bypass time is defined as follows:

par 61 summer bypass time 12 ( 12 x 10 = 120 sec )par 62 winter bypass time 18 ( 18 x 10 = 180 sec )

After this time every trip of the LP switch immediately stops the compressor.

10.2 HEAT LOW PRESSURE PRE-ALARM

The fan, only in winter operating , can be forced at the max. speed if the evaporating pressure falls down the valuedefined by par 65 SetPreBP1 .The forcing stops when the evaporating pressure goes up the value of par 48 DiffBP1 .The forcing is signalled by the automatic E 34 alarm.par47 BP1Enabled Enables the low pressure 1 pre-alarm48 DiffBP1 Low pressure 1 pre-alarm differential 3.5 bar65 SetPreBP1 Low pressure 1 pre-alarm set 0.5 bar

12 SET-POINT MANAGEMENT

The controller uses two set-points, one for summer and for winter

Par 32 Summer Set Point def = 5.7 °CPar 33 Winter Set Point def = 41.2 °C

In both cases the set-point is automatically limited within the max. and min. limits defined byPar 25 MAX Set Heat def = 51 °CPar 26 Min Set Heat def =22 °CPar 27 Max Set Cool def = 21 °CPar 28 Min Set Cool def = 5 °C

12.1 CORRECTIONS ON SET-POINT

The corrections are aimed at optimising the unit energy efficiency.

To achieve this, the corrections modify the set-point dynamically according to certain variables. For example, inthe summer operation with low external temperatures, thus with reduced load, it is possible to obtain an indoorcomfort with set-points even higher than the standard, thus with a higher energy efficiency

Correct Set Point (es 6.7 °C)

The static set-point can be modified dynamically with two CORRECTIONS based on as many

factors external to the unit:

• correction based on the external temperature/enthalpy

• correction based on the Water reset (signal 4-20 mA supplied by the customer)

The correct set-point, to which all corrections have been added or subtracted, is identified asACTUAL set-point and is displayed by the status n°1 ( see page 20 )

12.1.1 CORRECTION ON THE EXTERNAL TEMPERATURE

This function can be activated on the chillers only if the external air probe BT6 is installed (basic module, CN2 pin6 and 7)

SUMMERIn the summer operation with low external temperatures a reduced cooling demand is supposed.Thus, the indoor confort can be obtained even with set-points higher than the standard.In the summer operation, the correction is added to the set-point (thus it is increased while external temperaturedecreases. )

The max. value of the correction that can be applied is set by:Par 14 Max. value of summer correction 6 °C

The correction is active in the temperature range defined by:Par 10 External temperature for max. summer correction 15 °CPar 11 External temperature for min. summer correction 30 °C

This function can be used also with a different logic: increase the set-point while the external temperatureincreases.In this case, the required operation is opposite the previous one; the set values are thus reversed:

Par 10 External temperature for max. summer correction 30 °CPar 11 External temperature for min. summer correction 15 °C

WINTER

In the winter mode with mild external temperatures (e.g. 15°C) the thermal requirement is supposed low and thusthe room comfort can be reached with a lower set-point, too.The correction is thus subtracted from the set-point (thus it is decreased while the external temperature increases )

The correction is active in the temperature range defined by:Par 12 External temperature for max. winter correction 15 °CPar 13 External temperature for min. winter correction -5 °C

The above remarks apply here, too: the function can be used with a different logic:decrease the set-point while the external temperature decreases.The required operation is opposite the previous one; the set values are thus reversed.

CORRECTION ON THE EXTERNAL TEMPERATURE FOR COMPRESSOR OPERATING LIMITThis function allows to extend the operating limit lowering the setpoint when the external temperature decreases

par 73 enables correction for the ext temp limit 1=YESpar 74 external temperature for max heat setpoint - 2 °Cpar 160 external temperature for min heat setpoint -15 °Cpar 175 min value settable of the heat setpoint 35 °C

Enabling both the correction for the external temperature ( curve A ) and the correction for limit ( curve B ) , thecorrect setpoint has this performance :

12.1.2 CORRECTION ON ENTHALPYThe function can be activated only if the expansion PLUG-IN module and the humidity probe areinstalled.The enthalpy correction is active in the summer operation; in the winter operation the correction isapplied only on the external air dry bulb temperature (enthalpy value is not active).The logic is the previously described one: the lower the humidity content in the air, the lower the coolingdemand thus the set-point can be increased (compensated)

It can be used to maintain the system within the operating limits during unit OFF period.The MAINTENANCE set-point thus controls the temperature of the treated water when the unit is OFF or inStand-by.To achieve this, it activates periodically the circulation pump, it tests the water temperature and possibly activatesthe compressor.

Par 42 Summer maintenance Set Point 20 °CPar 43 Winter maintenance Set point 30 °C

It is enabled with the parameters:Par 44 Summer maintenance enabling 1 numPar 45 Winter maintenance enabling 1 num

With unit and pump OFF it starts counting the time:par 41 Maintenance scan time 1800 sec

at the end of the time the pump is activatedpar 144 Pumps in maintenance starting time 120 Sec

at the end of the time, if the set is not met it remains active with the compressor as long as the set is reached.

14 COMPRESSOR TIMING

The number of starts and thus the wear of the compressor are reduced as much as possible by the control systemwith 2 parameters.The max. number of starts/hour of the compressor is limited by setting the delay between a start and the followingrestart of the same compressor:

par 63 start time/ compr. start 360 secThe pressure equolization before the compressor restart is aided by setting the delay between a stop and a start ofthe same compressor:

15 COMPENSATIONS

The compensations are aimed at safeguarding the compressor;thus they prolong compressor�s operating time and limit the number of hourly start pulse sTo achieve this, the compensations add an OFFSET to the activation point of the compressor

COMPENSATION

By means of compensation, the compressor working point is taken away from the set, avoiding too short workingperiods.

The possible compensations are 3:

Compensation on the LOAD = based on the inlet-outlet water temperature difference

Compensation on the DUTY-CYCLE = base on the frequency and duration of the compressor ON-OFF cycles

Compensation on the DURATION = based on the compressor ON time

The compensation off-set is dynamically calculated and is the sum of the instantaneous values of the activecompensations.It cannot exceed the highest value among the maximum limits of the compensations; it can reach max. 3°C with thedefault parameters.

15.1 COMPENSATION ON THE LOAD

The compensation is based on the average temperature difference between water inlet and outlet.

If the average temperature drop is 5°C, that is thecompressor has always been active, the thermal load ishigh.

If the average temperature drop is low, this means thatthe compressor has stopped several times, thus thethermal load is low.In this case it is possible to compensate (namely to delaythe compressor start).

LOW load

Medium average

par 4 = 300 sec

HIGH loaddelta T °C

par 4 = 300 sec

low average temperature drop = low load = frequent compressor start pulse s + short operating periods

The highest compensation corresponds to the minimum average temperature drop, namely with inlet temperatureclose to the set-point.

The compensation of the load has a �mild� effect: it compensates max. 1°C.It is especially useful if the load is variable.

Multilizer demo

15.2 COMPENSATION ON DUTY-CYCLE

The compensation on DUTY-CYCLE is based on the ratio : operating time

Oper. time + stop time

This function is based on elaborate mathematical calculations and test checks.The resulting values are thus to be meant as standard and cannot be modified.Please note that the worst conditions occur for duty-cycle values included in the range between 20% and 50% (ONtime = 50 % OFF time) .

53 Enables compensation on duty 1 num54 Value of critic duty 20 %55 Max. value compensation on duty 1,5 °C56 Time of medium duty calculation 1800 sec

The compensation on the duty operates a standard optimisation of the ON-OFF cycles; thus, it is of generaluse and must be enabled always.

15.3 COMPENSATION ON THE DURATION

The compensation on the DURATION is based on the compressor ON time. Short ON times, even if followed bylong OFF periods, are critical for the compressor (lubrication problems).

That's why at the end of each operating cycle of the compressor the controller checks the duration (compressorON).If the ON time is lower than 200 sec the controller increases the compensation, then it checks if ON reaches 200sec; otherwise, it increases the compensation again. The compensation is increased max. three times the max.value.If the ON time is longer than 300 sec, the compensation is decreased with the same logic.

Par 57 It enables the duration of compensation 1 numPar 58 Min. operating time 200 secPar 59 Max. operating time 300 secPar 60 Max. duration comp. value 1 °C

The duration compensation has an �incisive� effect: it compensates up to 3°C.It is useful when the water content is limited.The incisiveness is detrimental to the low temperature control accuracy: in industrial applications, where a finetemperature control is required, this compensation can be disabled but a fair water quantity in the system isnecessary.PLEASE NOTE THAT WITH SHORT COMPRESSOR ON PERIODS IT IS POSSIBLE TO HAVE ALOW AVERAGE TEMPERATURE DROP; IN THIS CASE, THE LOAD COMPENSATION WOULDHAVE A LIMITED EFFECT.

16 TEMPERATURE CONTROL

The temperature control is based on the outlet temperature and is based on temperature drop between water inletand outlet defined while designing the system

Par 37 Summer temperature average 5 °CIf the temperature drop on the system is not 5°C, it is basic to update the parameter value to the current temperaturedrop on the system; otherwise, the adjustment logic is distorted.The cooling/heating capacity supplied by the individual resources is defined (capacity step):

single capacity stepthe compressor alone supplies 100% of the required power (SUMMER)

double capacity stepthe compressor alone supplies only a part of the required power (WINTER with electric heaters)

Par 72 Compressor output capacity 70 %Par 177 Output by the integration heaters 30 %

The controller can activate one and only one step at a time, and only after the activation scanning time (status 4 ,page 20) .The activation scan time is not fixed, rather it changes according to the difference between water outlettemperature and current set-point value. The higher the difference value (both positive and negative) the shorter theinterval between scanning points.

Par 34 Max. activation scanning time 1200 secPar 35 Min. activation scanning time 120 sec

The release of active power steps can take place one step at a time, except the safety devices, when the releasescanning time has elapsed.

In this mode also the heaters can be installed and managed, that is a second capacity step integrating the first one.Thus, the total capacity is distributed between compressor and electric heaters.Compressor ON if :

at the end of the scanning time the outlet water temperature is below the current set-point (which considersthe possible corrections) plus the capacity supplied by the single capacity step of the compressor.

21.4 WATER COOLED UNITS

The differences with respect to air cooled units are the following:• no defrost cycles.• The coil temperature probe becomes external exchanger inlet probe, necessary on heat pumps to check

the min. water temperature at the inlet (antifreeze).• Input 3 of the CN1 connector is used for differential pressure switch of external exchanger.• Condensation is kept under control sensing only the relevant pressure (no temperature control)

WATER VALVE MODULATIONThe valve is closed with steady compressor.When the controller requires capacity the water valve opens by the extent set by the parameter:

par 104 % Fan at start 70 %This step has a duration, in seconds, equal to:

par 100 Fan start pulse duration 5 secafter this time the system checks the condition of the water differential pressure switch.

If it is closed, the compressor can start and the water valve starts modulating according to thecondensing/evaporating pressure and takes at least the min. opening percentage set by the parameters:

par 94 Pressure for max fan speed heat 3.7 barpar 95 Pressure for min fan speed heat 4.2 barpar 96 Pressure for max fan speed cool 17 barpar 97 Pressure for min fan speed cool 13,5 bar

if the pressure switch is open the compressor cannot start and an alarm is signalled.

A valve closing delay vs. the compressor stop, set by the parameter:par 107 water flow bypass time 0 sec

FLOW ALARM MANAGEMENTThe water flow alarm is not detected:

• with compressor steady• at during valve modulation start-up ( par 100 )• while modulating ( SUMMER : par 96 / 97 ; WINTER par 94 / 95 )• in this situation the differential pressure switch could have problems in detecting the flow presence.

Therefore the alarm is thus active only if the start-up time has elapsed and if the valve is completely open.The alarm resets automatically, a delay of 30 seconds starts together with the alarm signalling (compressor stop /start time = par 64 , see page 28), after which the alarm is reset and the delay of the flow bypass time (TstartUp)starts again; now the cycle is repeated, as long as the flow check is positive.

OPERATION OF THE ON-OFF TYPE WATER VALVESThe valve is closed with steady compressor and the flow alarm detection is inhibited.With active compressor, the valve opens immediately and the delay of the water flow alarm bypass time in theexchanger starts.While operating, the alarm detection is always active, as there is no valve modulation.As for the rest, the alarm detection and reset logic is the same as described in the previous paragraph.Also in this case, too, there is a valve closing delay vs. the compressor stop:

par 107 Water flow bypass time 0 sec

22 RADIATING PANELS

The following is necessary for the management:• expansion PLUG-IN module• radiating panel water temperature probe• external air temperature probe• external temperature radiating compensation enabling

The system return water for uses such as FanCoil is used to supply a floor system with radiating panels.A set-point is fixed for the outlet water to the radiating panels.If the water temperature is lower than set point, the valve deviates the water flow returning from the fan coil to theradiating panels.If the water temperature is higher or equal than set point, the valve will close and the panels will work only withtheir own recirculation water.The water outlet pump to the radiating panels is controlled in parallel with the pump to the exchanger installed onthe machine. Thus, it is always active when the chiller is set ON and switches off with a delay that can be set fromthe machine setting OFF.

22.1 VALVE CONTROL TO THE PANELS

As alternative, it is possible to control 3-point or proportional valves.There are 3 outputs for radiating panels:

• analogue 0-10 V• valve opening digital• valve closing digital

CALCULATION OF THE START THRESHOLD OF THE RADIANT VALVE CONTROLThe outlet temperature threshold for the control start is calculated with the parameter 169 TdeltaChiller :

Active control Inhibited control

COOL t mandata < SetPointRAD � 2 °C t mandata > SetPointRAD + 2 °C

HEAT t mandata > SetPointRAD + 2 °C t mandata < SetPointRAD � 2 °C

22.2 RADIANT SET-POINT

There are 3 modalities to set the radiant .

1. Value setting by parameter or by ModBus variable.The valve is managed to obtain water on the panels at the parameter value �192 SetPointTR� independentlyfrom the operating mode selected on the chiller.

2. Set point calculated in function of the external air temperature.The electronics determinates two reference set point ( summer / winter ) that are set automatially in base ofthe operating mode selected on the unit. This configuration is obtained setting �190 EnCompExttR = 1�

3. Summer set point correction in function of the dew temperature value.The system must be interfaced with a ModBus (Ex ElfoControl) net Master, able to communicate theambient UR and the ambient temperature values thorough the serial. In function of these information, analgorithm inside the board allows to correct the min. summer set point if the dew temperature valuecalculated is critical. This configuration is obtained setting �191 EnCompRugiada = 1�

2 - HEATINGWhile the external temperature increases, the heating demand decreases, and thus can be complied even with alower set-point (increasing the power efficiency).

3 - INTERFACING WITH ELFO CONTROL

It is possible to calculate the set to activate the radiating panel valve preventing from condensing water rising.

This operation must be enabled by the parameter:191 Enables the compensation for condensing in cooling mode. 1 num

The controller processes the information coming through serial part from Elfo Control (Zone Master):• Ambient temperature• Ambient relative humidity• Ambient Set-point

The controller calculates the so-called dew point, according to these values, re-defining the values of• Min. set point in cooling• Max. set point in cooling

The dew compensation is automatically deactivated if a communication problem does not allow the values to betransmitted by the Elfo Control to the unit; only the compensation for external temperature remains active in thiscase.

22.3 RADIATING PANEL WATER ANTIFREEZE SAFETY

With unit steady possible freezing in the radiating panels must be prevented.Thus, a radiating water ANTI-FREEZE alarm function is active based on the temperature of the water outlet tothe panels, with the same parameters seen for the anti-freeze alarm for the evaporator water described on page 23

Multilizer demo

When the alarm is activated :• the radiating water pump outputs are automatically activated• the radiating valve sets in opening towards the floor panels (recirculation on panels).

When the probe detects a value over the differential for the recovery,• the alarm is AUTOMATICALLY reset• the pump and the valve are piloted again with the standard logic based on the radiating set-point

and on the outlet temperature.

22.4 COOLING LIMITING BY DIGITAL INPUT.

To prevent from condensing it is possible to control a signal from external digital contact to be connected with thebase module, CN1 pins 5 and 11

The regulation logic is the following:Input Closed = Standard operationInput Opened = Valve in full recirculation position on the radiating panel side

The logic is active if:• the unit is in cooling mode• par 203 = 1 Enables Cooling Limit

With active logic, a signal for �Cooling limit� alarm is enabled with AUTOMATIC reset.

23 DEFROSTING

Defrost can occur when:• the unit is working as heat pump• the compressor is active.

The cycle starts with:• a pressure test

� a defined threshold is exceeded• a counting is started

o at the counting end the temperature is checked� If it is lower than a defined value

• defrosting starts.

COUNTING CALCULATIONThe counting, or basic delay time for defrost, is dynamic and is calculated in two ways: according to externaltemperature or to the enthalpy.EXTERNAL TEMPERATURE ONLY

The basic delay time for defrost increases while the external temperature decreases.Indeed, it is supposed that when the external temperature decreases the humidity rate in air decreases, andtherefore the need for defrost is lower.

0 SECpar 131

- 10 °C 5 °C EXTERNAL TEMP.par 134 par 133

EXTERNAL TEMPERATURE + HUMIDITYor enthalpy defrostThe basic delay time is determined according to the air specific humidity calculated through the humidityprobe (optional, to be declared present with par 156).

The BASIC DELAY TIME for defrost changes depending on the variation of evaporating pressure (ratio).Practically, if the pressure:• decreases quickly the coil is icing and thus the counting must speed up• decreases slowly the counting can slow down• is stable (with low values, too) the counting keeps the values according to the graph above.

For example if the pressure in 1 minute falls down of 1 bar ( par130=1) , at every second the time is decreased of 4seconds ( par 129 ) .

Multilizer demo

Switch to defrost:• keeps the compressor active• the refrigerating circuit direction is reversed through the 4-way valve• The fans are stopped and the low pressure by-pass is active at reversal.• The safety devices remain active• Defrost is performed even if the controller does not require the step anymore.

Defrost end:• by temperature or max. time• the compressor is stopped• the compressor can restart in heating after having counted the dropping time or the compressor safety

times• the fans are activated at max. speed for 15 sec (par 136)

if the external temperature is over 3°C (par 137)

Setting the par 135 dropping time at 0, the compressor is not stopped at the of the defrosting but it remains active.

FORCING DEFROST FOR LOW PRESSUREIn special situations sudden drops in the evaporation pressure can occur (typically while counting the delay time fordefrosting, that is with low pressure/external temperature and with high humidity).The defrost forcing prevents such situations.It is active only if the counting of the delay time for defrost has been active for at least 10 minutes.Defrost starts immediately if the pressure drops below 1.4 bar (par 138 defrost forcing pressure), regardless of thetemperature value at the coil.

If this function is activated for more than 3 times, in the same circuit during one hour of machine operation, this issignalled in the alarm log.
