Core Product Functions:
1. Real-time High-Pressure Discharge Monitoring and Display
Continuously monitors discharge high pressure at the condenser and compressor, transmitting linear voltage signals to the CCM main controller. The control panel displays real-time pressure values, facilitating O&M assessment of refrigerant charge levels and heat exchange conditions.
2. Energy-Saving Staged Control of Condenser Fans
The mainboard automatically starts/stops fans and adjusts the number of active condenser fans based on high-pressure readings. It reduces fan power consumption during low loads and increases airflow during high-temperature, full-load operation, thereby stabilizing high-side pressure and reducing the likelihood of high-pressure protection shutdowns.
3. Staged High-Pressure Warning and Protection
When high pressure approaches warning thresholds, the unit preemptively limits slide valve loading and reduces compressor output. Excessive pressure triggers an interlock shutdown; combined with a mechanical high-pressure switch, this establishes a dual-layer safety protection system.
4. Closed-Loop Load Regulation via Screw Compressor Slide Valve
Linked to the chilled water outlet temperature, the system automatically adjusts the slide valve opening (0–100%) to balance the cooling load against system high-side pressure, minimizing unit surging and drastic fluctuations in high and low pressures.
5. Precise Fault Self-Diagnosis and Reporting
The main controller detects anomalies—such as open circuits, short circuits, or signals outside standard ranges—and reports high-pressure sensor faults. The unit locks out loading operations, enabling rapid identification of wiring or sensor failures.

Product fault symptoms:
The unit reports a high-pressure sensor fault immediately upon power-up and self-test; the high-pressure reading on the panel drops to zero, freezes, or drifts significantly;
Condenser fan start/stop logic is erratic; high pressure spikes continuously during full-load summer operation, causing frequent high-pressure shutdowns;
Slide valve loading is sluggish, resulting in insufficient cooling capacity and chilled water outlet temperatures failing to meet specifications;
Water ingress and corrosion at the Packard connector cause intermittent loss of pressure signals and random unit load limiting;
Diaphragm rupture leads to refrigerant leakage at the threaded base; both high and low system pressures are consistently low, indicating a persistent refrigerant shortage;
Internal circuitry has aged, causing false alarms and shutdowns before the high-pressure protection threshold is actually reached.
