AIR CONDITIONER OPERATION
THERMOSTAT Control Switch
Once the THERMOSTAT is set to the desired temperature, the room
temperature will be automatically adjusted without excessive or insufficient
cooling/heating and thus a comfortable environment is always maintained.
The THERMOSTAT controls the compressor only, and accordingly the fan is
constantly circulating air even during the period when the compressor is off
during cooling/heating operation.
1. When you wish to lower the temperature, turn the THERMOSTAT Control switch
clockwise in the direction of the higher numbers of the dial.
2. When you wish to increase the temperature, turn the THERMOSTAT Control
switch counterclockwise in the direction of the lower numbers.
NOTE:
●
When the THERMOSTAT Control switch is set at positions "5", "6" or "7"
comfortable room temperatures can usually be obtained. Please note that
it is unhealthy for the room temperature to be lower than approximately
22°C.
●
When the THERMOSTAT Control switch is set at positioned at "10", the
room-side fin coil may freeze up and prevent effective cooling. If this
happens, turn the switch to "FAN", and turn the THERMOSTAT Control switch
counterclockwise.
CAUTION
When cooling/heating is stopped by means of either the MASTER CONTROL
or THERMOSTAT Control switch do not restart cooling/heating for at least
3 minutes.
● If cooling/heating is restarted within this time, the compressor motor will be
subjected to an over current and a compressor motor safety device will be
actuated. If this occurs, restarting cooling/heating will not be possible for
about 20 minutes.
