F. Microprocessor ControlThese air handling units are provided with a microprocessor control board incorporating the following features:
- BALANCE LOADING OF COMPRESSORS:The units electronic control automatically operates lead/lag sequenceof compressors. This is to load the compressors evenly over long periods of operation. If required however, compres-
sor-1 can also be set to always lead. In this case, compressor-1 always starts first and stops last. (Selectable throughdip switch setting on control board).
- PUMP DOWN FUNCTION: In units equipped with pump down system, the controller provides the time delay between
solenoids opening and compressor starting to equalize the pressure in the system necessary for compressor to start-up. (Selectable through dip switch setting on control board).
- COMPRESSOR ANTI-RECYCLING PROTECTION:The controller has a built-in 3 minutes minimum off timer for
compressor. This is for compressor protection in case of accidental manual re-set or immediate re-cycling of thermo-stat due to load demand.
- COMPRESSOR LOCK-OUT FUNCTION: If any of the units safety control trips due to abnormal conditions, theelectronic controls locks out the compressor after a pre-determined timing preventing a re-start unless attended by a
qualified service technician. The unit can be re-started through thermostat re-set after ensuring safe system condi-tions.
- FAULT DIAGNOSTICS: In case of system fault, LEDs on the board emits a flashing signal indicating where the faultis. This is to guide the service technician in identifying the fault.
- DIGITAL I/Os: The units control board is compatible to operate with a DDC controller or any standard 24V a.c.thermostat commercially available.
- SEQUENTIAL CONTROL: With input signals from the thermostat, the motors in the equipment is started in sequen-
tial order: supply fan condenser fan compressor; at a pre-determined timings.
G. Control PanelA complete factory-wired control panel is provided to ensure safe and proper operation.
OPTIONS AND ACCESSORIESA. Electric HeatersElectric heaters are of the resistance open coil type and conform to the requirements of UL 573 or equivalent. Electrical
characteristics, kW capacities and number of stages are as indicated. Thermal cut-outs, fusible links and airflow switchesare provided to shut-off power to heaters in case of airflow failure.
B. FiltersFilters are easily accessible through the filter access panel. Filters may be synthetic or permanent washable aluminumtype (refer to model decoding for details). As an accessory, bag filter section can be provided for belt driven units.
C. Discharge Air Plenum & Return Air GrilleAs an accessory, discharge air plenum with return air grilles can be provided on vertical units.
D. UV Flow Light EmittersThe damp & dark environment inside the AHU is ideal for the growth and development of hazardous bacteria & fungi. The
UV flow concept uses emitters of Ultra Violet light to simulate the effect of healthy sun radiation. This will inhibit the growthof these microorganisms reducing in this manner mold related allergies and diseases. Breath safely with UV flow.
To order the UV flow use the kit numbers in the table below.

Scroll compressors are designed to operate in single direction only. Hence, care has to be taken to ensure correct
rotation when the system is operated. Verification of correct rotation is by observing that the suction pressure drops and
discharge pressure rises when compressor run. Reverse rotation results in abnormal sound, as well as, substantially low
current draw and by interchanging power supply wire L1 & L3 will correct this problem.
The operation of the air conditioning unit is controlled by a 24VAC electronic control board.
GENERAL
The thermostat normally displays room temperature and mode of operation. The five buttons on the front of the unit
allow complete control of the thermostat. The thermostat also allows to select continuous fan operation (useful whenusing an air cleaner) or have the fan come on with the compressor.
SWITCH FUNCTION
- On/Off Key : Switch the system On or Off.- Up Key : To increases the set temperature.
- Down Key : To decreases the set temperature.- Mode Key : Changes the mode to Fan, Cool, Heat or Auto.
- Fan Key : Changes the Fan Operation to Auto or Continuous.- C/F selection : By pressing Mode & UP key together, toggles between C to F or vice versa.
USER CONTROLS
Mode:
Select the desired mode of operation by pressing of the mode button:
Fan: In this mode of operation, the compressor will be in inactive state. Display shows room temperature. Fan will be running.
Cool: In this mode of operation, the compressor will be ON after a delay depending on the differential of room
temperature & Set temperature.
Heat: In this mode of operation, Fan is ON.
Auto : In auto mode, thermostat provide automatic changeover from heating to cooling mode & vice versa. Ther-
mostat automatically switches to maintain the desired temperature.
DIP SWITCH OPTIONS AND FUNCTIONS
There are 4 small DIP (Dual in line package) switches on the back of the circuit board which must be configured by
the installer.

INSTALLATION INSTRUCTIONSA. GENERAL
Blower units are shipped completely wired. Only external power, interconnecting control wiring between outdoor andindoor units and refrigerant pipe connections are needed to complete the installation. For detailed instructions/informa-
tions, please refer to corresponding IOM manual.
B. UNIT LOCATION & ACCESS SPACEThe placement of the unit in relationship to the building is very important. A minimum of 36 inches clearance must be
kept on the service access side and return air side.When making tubing connections, be sure to provide clearance for electrical connections.
C. TUBING INSTALLATION
Do not remove plugs from the compression fittings until tubing has been run and is ready for connection.
a. Make sure the tubing is round, without dent or burrs.
b. Cut tubing to the length required with a tube cutter carefully. Do not use a hacksaw.
c. Remove burr from inside and outside using file or deburring tool.
NOTE: Always use a gear type tube bender when making bends in suction line.
When installing tubing through walls or along side of any structural members, be sure the tubing is isolated from thesemembers or walls to avoid any transmission of vibration that may occur, while unit is running.
ELECTRICALSTEP 1: INSTALLATION
A)Please ensure power supply to the unit is as per unit nameplate (Volts/Ph/Hz) requirements.
Caution: Operation of the unit on improper power supply will result in damage to the unit.NOTE:Use copper wires of proper rating for all field wiring.
Warning
Before servicing or installation of the unit, always TURN OFF all power to the unit. There may be more than one discon-nect switch. Ensure all of them are turned off. Electrical shock can cause personal injury or death.
B) Ground & power wires
Connect power wires to terminal block per wiring diagram.
Connect ground wire to the ground lug inside the control box.
C) Control wiring between outdoor & indoor unit
Use 16 gauge color-coded wire between the indoor and outdoor units (control wiring).
STEP 2: START-UPRefer to outdoor unit installation instructions for system start-up instructions and refrigerant charging method details.
STEP 3: SEQUENCE OF OPERATIONWith power supplied to indoor and outdoor units, the unit starts responding to the thermostat mode requirement.
Cooling mode: When thermostat calls for cooling, the blower motor in the indoor unit is switched on. The compressorcontactor is energized to start the compressor and condenser fan.As the conditioned space approaches the thermostat cooling set point, the unit cycles off.
Heating mode: When thermostat calls for heating, the blower motor in the indoor unit is switched on. The contactor forelectric h
