The Dixell iChill IC100 controller series is the answer to the requirements in controlling real chiller and heat pump installations. These can be of the following types:
- air/air
- air / water
- water / water
- dehumidifiers
The advantages of these controllers include:
- forced defrost
- combined defrost
- cooperation of two compressors
- open collector output with polarity adjustment
- load reduction function
- alarm management even in standby mode
- alarm deletion protection
- 0...10V analogue and PWM output for capacitor control
- NTC, 4...20mA, 0...5V analog input (optional)
- optional RTC (Real Time Clock)
- power saving function
- easy programming with HotKey or ProgToolKit
- TTL output for conversion to RS485
The Dixell IC121C iChill controllers are designed to control single circuit chillers, heat pumps and similar refrigeration circuits that contain one or two compressors. In addition to controlling the compressors, they allow you to control the four-way valve, process temperature and pressure protection signals, flow meters, control solenoid valves, control fan speed, start water pumps, heating coils and other components used for these systems. A typical wiring example, including the components being controlled, is shown in the following figure.
