The Dixell iChill IC200 controller series is the answer to the requirements in controlling real chiller and heat pump installations. This series allows to control and manage chillers (with two circuits and up to 6 compressors, with reversibility), heat pumps and chillers. With the compact controller you get the possibility to control and monitor the following types of systems:
- air/air
- air/water
- water / water
- dehumidifiers
The advantages of these controllers include:
- forced defrost
- combined defrost
- compressor cooperation
- extraction function (for start and stop)
- open collector output with polarity adjustment
- load reduction function
- alarm management even in standby mode
- management of screw compressors
- alarm deletion protection
- 4...20mA, 0...10V, PWM outputs for capacitor fan control
- NTC, 4...20mA, 0...5V analog inputs
- load control based on dynamic setpoint
- compressor winding switching triangle-star for start
- internal data logger (100 alarms)
- RTC (Real Time Clock)
- device on/off based on time zones
- energy saving function
- easy programming with HotKey or ProgToolKit
- RS485 ModBus output
The Dixell IC291D iChill controllers are designed to control two-circuit chillers, heat pumps and similar refrigeration circuits that contain up to six compressors. In addition to controlling the compressors, they can control four-way and reversing valves, process temperature and pressure protection signals, flow meters, control solenoid valves, dampers, control fan speed, start water pumps, heating coils and other components used for these systems. The Dixell IC291D iChill offers an All-in-One solution to control complex and powerful HVAC and HVAC solutions.
