1.5 Automatic Operation
Automatic Cooling / Heating Function (Heat Pump Only)
When the AUTO mode is selected with the remote control, 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 control setting temperature is set as automatic cooling / heating setting temperature
(18 to 30°C).
2. Main unit setting temperature equals remote control setting temperature.
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 control setting temperature: Cooling operation
Room temperature < Remote control setting temperature: Heating operation
Ex: When the set point is 25°C
Cooling Operation
→
23°C: Thermostat OFF
→
22°C: Switch to Heating Operation
Heating Operation
→
26.5°C: Thermostat OFF
→
