6.  Service Operation Circuit

 

●

  Use the service switch to select “Cooling” temporarily when the interior electric equipment has troubled.

 

●

  Setting the switch to “Cooling” causes continuous cooling room temperature control. To control the room 

temperature, turn on and off the disconnect switch. To protect the compressor, wait at least 3 minutes 
before turning on again.

 

●

  The fan speed is “MED”.

 

●

  Does not operate is 12V is not generated in the control circuit.

 

●

  When the service switch is used for operation, each change switch is overridden.

 

●

  Setting the service switch to “Cooling” turns on the “Power relay”.
