Cold room Control – Single & Three Phase

Cold Room control can Be donein a number of ways from simple Mechanical Thermostat to high end Electronic controls.

Danfoss offers all of the above,But today we will focus on theElectronic Controls for Single andThree Phase systems.


ERC 21x


ERC 21x Project Scope

• Introduce a new low-mid end product range to gain market share in the Commercial Refrigeration segment with focus on the following applications:

Easy Menu Structure

- The parameters are structured in

groupswhich makes finding the right

parameter a lot faster.

- We introduced quick installation and

service menus to make installation

and service faster.

- Alphanumeric codes for easy

recognizability


Patented

Largest Display in Product ClassERC 21x has a display size of 29X17 cm which is largest among our competitors

Support widest range of sensorsNone of the main competitors support 4 types of Sensors. This gives ERC 21x maximum flexibility in replacement sales

No compromise on accuracy with deviation of+/- 0.5K Between -35 to +25˚C+/- 1K Between -40 to -35˚C +/- 1K Between +25 to 105˚C

Flat Front Design Most of our competitors do not have Flat front Design with clear feedback on button click and no grooves around buttons, which makes it easy to clean and also avoid filth

EU Design

Registration

Longest LifeWith Zero Cross Technology on all relays, ERC 21x’s life increases up to 33% (2 years) longer as compared to competitors

ReliabilityNone of the main competitors protects the compressor by monitoring:- the power supply voltage level- the condenser temperature with 2

levels of alarms

Application Based setupERC 21x has pre configured applications making setup quick and easy

OPTYMA Control – programming

Level 1 – Programming (User Level)To gain access to the Level 1 configuration menu proceed as follows:

1.Press the UP (▲) and DOWN (▼) keys simultaneous and keep them pressed for a few seconds until the first program variable appears on the display.

2.Release the UP (▲) and DOWN (▼) keys.

3.Select the variable to be modified using the UP (▲) and DOWN (▼) keys.

4.When the variable has been selected it is possible to:•display the settings by pressing the SET key •modify the setting by pressing the SET key together with the UP (▲) and DOWN (▼) keys.

When configuration values have been set, you can exit the menu by pressing the UP (▲) and DOWN (▼) keys simultaneous for a few seconds until the cold room temperature appears.

5.The new settings are saved automatically when you exit the configuration menu.





Level 2 – Programming (Installer Level)To access to the second level press the UP (▲) and DOWN (▼) keys and the LIGHT key simultaneous for a few seconds.

When the first programming variable appears thesystem automatically goes to stand-by.

1.Select the variable to be modified by pressing the UP (▲) and DOWN (▼) keys. When the parameter has been selected it is possible to:

2.View the setting by pressing the SET key.

3.Modify the setting by holding the SET key down and press the UP (▲) and DOWN (▼) keys.

4.When configuration settings have been completed you can exit the menu by pressing the UP (▲) and DOWN (▼) keys simultaneous and keeping them pressed until the room temperature reappears.

5.Changes are saved automatically when you exit the configuration menu.

6.Press the STAND-BY key to enable electronic control.
