BR1-27
Refrigeration Controller for DIN Rail
The BR1-27 is a real-time defrost controller, ideal for all supermarket and service applications.
With its 6 freely programmable real-time defrost times, which are also easily adjustable in the Info Menu, it is particularly suitable for all applications where time-controlled and optimised energy distribution of the respective system is crucial.
Properties
- Cooling or heating control freely selectable via Relay 1
- FLEXICOLD function for energy saving or control via 2nd setpoint
- Ability to control combination cabinets (chiller / freezer)
- Defrost by regular cycles or real-time
- Defrost timer memory in case of power failure
- Ability to control a second compressor or evaporator
- Absolute or relative temperature alarm control and door alarm
- Temperature / pressure monitoring and condenser maintenance alert
- Light and Standby control via M or ON / OFF button
- Quick programming using ZOT handheld programmer
- RS485 interface for integration into monitoring systems
Functions
- 16A evaporator fan relay, specifically for use with EC motors
- Optimised evaporator fan control via temperature
- 2 parameter groups for optional control of:
- ECO energy management with improved savings potential
- Chiller and freezer
- Day and night operation
- Time-controlled actions via start and stop time, such as:
- 2nd parameter group
- Activation of AUX outputs (e.g.: lights, valves, pumps etc.)
- Defrost synchronisation possible between multiple controllers
- Recording according to TK regulation via sensor T3
- Universal power supply 100…240Vac
Applications
- Control cabinet systems
- Compact refrigeration controls
