Room Temperature Control (Compressor Control)

Operating frequency of a compressor is decided according to temperature differences between remote controller setting and
room temperatures. By adding a relative method, based on current frequency, which gives frequency changes, a room
temperature is adjusted.
9.3.1. Cooling Operation
9.3.1.1. Thermostat Control
[Thermostat-ON Temperature] = [Intake Air Temperature] -
[Remote Controller Setting Temperature] < -1.5°C
[Thermostat-ON Temperature] = [Intake Air Temperature
after 2 minutes] - [Remote Controller Setting Temperature]
< -1.5°C
When Room Temperature is below Thermostat-OFF
Temperature for 3 minutes or more, it turns to Thermostat-
OFF.
The maximum power is applied only for the first 30 minutes
of the operation, after that, rated power is applied. If the
POWERFUL Switch is pressed during operation, the
maximum power will be applied for 30 minutes.
9.3.2. Dry Operation
9.3.2.1. Thermostat Control
The unit can be operated in the Scrolling Dry Operation by selecting Cooling DRY mode with the DRY button on the remote
controller.
[Thermostat-OFF Temperature] = [Intake Air Temperature] - [Remote Controller Setting Temperature] > -2.0°C
When Room Temperature exceeds Thermostat-OFF Temperature for 3 minutes or more, it turns to Thermostat-OFF.
The fan speed setting is selectable.
9.3.3. Heating Operation
9.3.3.1. Thermostat Control
[Thermostat-OFF Temperature] = [Intake Air Temperature]
- [Remote Controller Setting Temperature] > +2.0°C
[Thermostat-ON Temperature] = [Intake Air Temperature
after 2 minutes] - [Remote Controller Setting Temperature]
< +2.0°C.
When Room Temperature
Temperature for 3 minutes or more, it turns to Thermostat-
OFF.
When operation in rated power continues for 3 minutes or
more, it turns to the maximum power.
Five stages manually and one stage automatically (QUIET). (Same as Cooling mode.)
