Key Features & Functionality
- Dual Mode Capability: Can be configured for either Cooling (compressor cuts off at set point) or Heating (heater cuts off at set point).
- Compressor Protection: Built-in time delay (Parameter P6) to prevent the compressor from short-cycling, extending its lifespan.
- Safety Backup: In the event of a sensor failure, the controller can be set to run the compressor on a duty cycle to prevent stock loss.
- Memory Retention: Settings are stored in a non-volatile EEPROM memory, so they aren't lost during power outages.
- Keypad Lock: Features a lock (LP) to prevent unauthorized tampering with temperature settings.
Common Applications
- Refrigeration: Deep freezers, walk-in coolers, and pastry cabinets.
- Kitchen Equipment: Bain-maries, ovens, and steam bath systems.
- Industrial: Water chillers and general temperature regulation.
Pro Tip:
If the display shows "Lt" or "Ht", it means the temperature has reached the Low or High limit set in the parameters. If it shows "PP", there is likely an issue with the NTC probe or its connection.
