Application
The controller is a complete control unit for refrigeration
appliances with integrated refrigeration-technical functions
capable of replacing a setup of thermostats and timers.
The relays are used for operating:
- Compressor
- Fan
- Defrost
- Alarm
- Light
The controller can operate one evaporator.
Operation
The controller comes without operating buttons on the front
panel, and it will require no operation once it has been set and
started up.
When the controller is operated, it can be done in one of the
following ways:
• Connection of an external display with operating buttons
- The display will currently show measurements and settings in
the menu system
- In case of malfunction the relevant error code will be shown on
the display
- Four light-emitting diodes will show the system’s actual
function:
› refrigeration
› power for the AKV valve
› defrost
› fan operating
› when there is an alarm the three LED’s will ash
• Data communication
The controller can be hooked up with other products in the
series of ADAP-KOOL® refrigeration controls. The operation,
monitoring and data collection can then be performed from a
PC – either on site or at a service company.
Customer display
If the temperature in the appliance is to be visible to, say,
customers, a display can be mounted.
Inject ON function
The expansion valve closes when the signal at the 230 V input is
removed or receives a signal via the data communication. In this
way it is ensured that the expansion valve will not charge the
evaporator when the compressor has stopped.
(The threading of the function may be cancelled via a setting).
Digital input
A digital input can be dened for one of the following
applications:
Door alarm
Defrost start
Night operation
Start/stop of regulation
Joint defrost start/stop with a master/slave function
Light relay
The function of the relay will follow the day/night function, but
can be recongured so that it follows the door function via the
digital input.
Rail heat function
If a rail heat function is required one of the following relays can be
redened, so that it can be used for rail heat control. This redeni-
tion can be made either on the alarm relay, compressor relay or
light relay.
Data communication
The controller is provided with LON RS 485 data communication.
