Controls and Safeties
- Chiller is completely factory wired and tested.
- Temperature control is based on leaving chilled liquid solution temperature. Temperature accuracy shall be + - 1°F.
- Controls includes the following components: 24vac transformer to serve all controllers relays and control components, Microprocessor based liquid solution temperature controller, Leaving water temperature thermistor, Pump bypass timer, Compressor recycle timer, Optional low pressure bypass timer for low ambient operation, Optional fan cycling control for low ambient operation, Chilled liquid solution flow switch.
Unit is equipped with thermistors and all necessary components in conjunction with the control system to provide the following protectants.
- Low refrigerant pressure.
- High refrigerant pressure.
- Low chilled liquid solution temperature.
- Low chilled liquid solution flow.
- Thermal overload.
- Short cycling.
- Unit is capable of starting and running at outdoor temperatures from 55°F to 120°F.
- Optional Low Ambient Kit allows starting and running at outdoor temperatures to -20°F (except for the 10 Tons Chiller which can operate at out door temperature 0°F and above). A field supplied and installed crankcase heater must be used when operating at these temperatures.
- Unit is capable of starting up with a maximum 80°F and a sustained 70°F entering fluid solution temperature to the evaporator.
- Minimum 10% Glycol solution is always required.
- For outdoor temperatures below 32°F, reference MAC Glycol Solution Data table.
- Primary electrical power supply shall enter the unit at a single location.
- Electrical power supply shall be rated to withstand 120°F operating ambient temperature.
- Units shall be available in 1 or 3-phase power at the voltages shown in the equipment electrical data.
- Control points shall be accessed through terminal block.
