Features
Control Features:
- Two easy-to-read LED digital displays show “Actual” and “Setpoint” temperatures
- Manual reset of safeties from front panel eliminates need to open chiller cabinet
- Thirty minute deviation delay stops nuisance alarms during start-up and setpoint changes
- Compressor cycling delay prevents short cycling
- PID control program algorithm provides ± 1°F / °C accuracy
- High/low temperature deviation alarm
- Power failure indicator signals brown out
- Low-flow protection
- Diagnostic lights that indicate: no flow, high and low refrigerant pressure, freezestat, over and under setpoint, pump on, compressor on, partial load, probe fault and optional low water level and water make-up
- Electronic hot gas bypass for stable capacity control
- Air-cooled units have copper tube / aluminum finned condensers and includes air inlet filter (optional on one-ton unit)
- Remote condenser units include a galvanized steel remote condenser with fans and copper tube / aluminum fin coils with a nitrogen holding charge
- Compressor, pump and condenser fan starters mounted and wired to motors
- Single-point main power block for simple wiring connection
- Freezestat safety switch with solid state sensor
