: Calibration and probe type selection (e.g., converting bar to °C). AL (Alarms) : High/Low pressure thresholds and delay times. Vital Parameters to Check: Description Default/Typical St1 Suction Setpoint Depends on gas type rE1 Suction Differential 1.0 - 2.0 bar St2 Condensing Setpoint 12.0 - 15.0 bar nCo Number of Compressors ⚠️ Troubleshooting Common Alarms If your display is flashing a code, refer to this list: E1 : Suction probe failure (check wiring or sensor). E2 : Condenser probe failure.
Configurable up to 5 onboard relays (e.g., Compressor, Defrost, Fans, Alarms, Auxiliary) with ratings ranging from 2HP (8A) down to 5A resistive.
The front panel features a clear display and four tactile buttons for configuration. Button Functions
