Auxiliary Heat Lockout
- Above the selected temperature, auxiliary heat will only run during defrost operation.
- Selectable from from 0° to 40°F or off*.
- Below the selected temperature the compressor does not operate, except in defrost cycle.
- Selectable from -10°F to 45°F or off*.
- Limit excessive noise in and out of a defrost cycle.
- Selectable 0, 12 or 30* second delay.
- 0, 3 or 5* minute selectable delay between cycles to extend the life of the compressor.
- Auto shut off when control voltage drops below 16 VAC for more than 4 seconds. Selectable on* or off.
Random Start Delay
- Delays operation for random delay after power outage to protect the compressor and avoid brownouts.
- Selectable on* or off.
- All timing is accurate to +/- 5% of nominal over the full temperature and voltage range at 60 Hz.
- All timings are 20% longer when operated with 50 Hz power supply.
