(2) Cool mode
• In addition to fan mode (as described above), when the COOL ON/OFF button on the control
panel is pressed, the microprocessor turns on “COOL ON” indication of LCD and if the
temperature set point is less than the current room temperature, activates the compressor relay
(relay board) after 120 sec delay. This sends line voltage (230 VAC) to the J4 terminal (relay
board) and compressor auxiliary relay is excited. Then compressor and condenser fan motor
turn on (Cooling Operation).
• Condenser fan mode is automatically switched
depending on room temperature. When room
temperature is approximately. 100 °F (38 °C)
or greater, fan mode is switched LO to HIGH.
When room temperature is approximately.
95 °F (35 °C), fan mode is switched HI to LO.
