(4) Compressor time delay control (compressor protection)
• Compressor protection consists of a time delay program within the microprocessor. This
program prevents a heavy load from being applied to the compressor motor when restarting the
unit (cool mode) after a very short period of time. This “delay” is in effect any time the
compressor is turned on by either the COOL ON/OFF button, or power interruption restart
(automatic recovery.)
Specifications:
- Time Delay: 120 sec.
(5) Automatic restart and recovery function
• The microprocessor contains a feature that automatically restart the unit after power is lost and
regained, and also has memory to store and recover operation status in the even of a power
loss.
Status of memory during power interruption
• When the input power is off, the status items below are saved in the memory.
- Running status (on or off)
- Operating mode: Cool mode or fan only mode
- Set temperature
- Temperature mode (°F or °C)
- Fan mode: Fan operation mode (fan on) or fan stop mode (fan auto)
