Automatic Operation
Automatic Cooling / Heating Function (Heat Pump Only)
When the AUTO mode is selected with the remote controller, the microcomputer automatically
determines the operation mode from cooling and heating according to the room temperature
and setting temperature at the time of the operation startup, and automatically operates in that
mode.
The unit automatically switches the operation mode to cooling or heating to maintain the room
temperature at the main unit setting temperature.
Detailed
Explanation of
the Function
1. Remote controller setting temperature is set as automatic cooling / heating setting
temperature (18 to 30°C).
2. Main unit setting temperature equals remote controller setting temperature plus correction
value (correction value / cooling: 0 deg, heating: 2 deg.).
3. Operation ON / OFF point and mode switching point are as follows.
1
Heating
→
Cooling switching point:
Room temperature
≥
Main unit setting tempe2.5 deg.
2
Cooling
→
Heating switching point:
Room temperature < Main unit setting temperature –2.5 deg.
3
Thermostat ON / OFF point is the same as the ON / OFF point of cooling or heating
operation.
4. During initial operation
Room temperature
≥
Remote controller setting temperature: Cooling operation
Room temperature < Remote controller setting temperature: Heating operation
