AH1-5
Refrigeration controller with counter-heating function
The AH1-5 is an electronic unit specifically developed for use in refrigerated vehicles.
Due to its variable 7 … 30 Vdc power supply, the AH1-5 can be integrated directly without additional voltage converters.
Additionally, the AH1-5 includes all the functions of a deep-freeze refrigeration controller.
Properties
- Cooling and heating control with neutral zone
- FLEXICOLD function for energy saving or second setpoint switching
- Defrost via timer or remote start
- Option to control a second compressor or evaporator
- Optimised evaporator fan control
- Light and standby control via M or ON / OFF button
- Rapid programming via ZOT-AH1 handheld programming device
- RS485 interface for integration into monitoring systems
Applications
- Small cold rooms
- Refrigerators
- Refrigerated counters
Advantages
- Ideal for refrigerated vehicles due to 7 … 30 Vdc power supply
- Particularly suitable where counter-heating is required due to external influences!
