1.6 Automatic Operation
Outline Automatic Cooling / Heating Function
When the AUTO mode is selected with the remote controller, the microcomputer automatically
determines the operation mode as cooling or heating according to the room temperature and
the set temperature at start-up, and automatically operates in that mode.
The unit automatically switches the operation mode to maintain the room temperature at the set
temperature.
Detail Ts: set temperature (set by remote controller)
Tt: target temperature (determined by microcomputer)
Tr: room thermistor temperature (detected by room temperature thermistor)
C: correction value
1. The set temperature (Ts) determines the target temperature (Tt).
(Ts = 18 ~ 30°C).
2. The target temperature (Tt) is calculated as;
Tt = Ts + C
where C is the correction value
.
C = 0°C
3. Thermostat ON/OFF point and mode switching point are as follows.
Tr means the room thermistor temperature.
Heating
Cooling switching point:
Tr
Tt + 2.5°C
Cooling
Heating switching point:
Tr < Tt – 2.5°C
Thermostat ON/OFF point is the same as the ON/OFF point of cooling or heating
operation.
4. During initial operation
Tr
Ts: Cooling operation
Tr < Ts: Heating operation
Ex: When the target temperature is 25°C
Cooling
23°C: Thermostat OFF
22°C: Switch to heating
Heating
26.5°C: Thermostat OFF
27.5°C: Switch to cooling
(R11893)
Target temperature + 2.5˚C
Heating Operation
Target temperature – 2.5˚C
Cooling Operation
Target temperature + 1.5˚C
= Thermostat OFF
Target temperature – 2.0˚C
= Thermostat OFF
