4-12-1. Indoor Air Temperature Control
The thermostat is switched on and off in accordance with
T= (Indoor air temperature) - (Temperature set with the remote controller)
In the body thermostat mode
(setting at factory shipment)
In the remote controller thermostat mode Indoor air temperature = (Remote controller sensor)
* Shift Temperature
Only valid during heating operation. Set at 0 °C during cooling operation.
The settings at factory shipment during heating operation are as follows:
Wall Mounted type : 2°C
Floor Standing type : 0°C
All other types (4-way types, Concealed types, etc.) : 4°C
This function acts as the coefficient for adjusting differences in temperature caused by the height of the living
space from the floor to the ceiling (the temperature at ceiling height is higher) during heating operation.
The setting can be modified between 0°C and 6°C with mode [06] (Simple Settings Function) on the remote
controller.
: Thermostat ON
: Thermostat OFF
(1) Once the thermostat has been switched on, it cannot be switched off again by indoor air temperature control for
a period of 10 minutes.
(2) Once the thermostat has been switched off, it cannot be switched on again for a period of 3 minutes.
(3) When in the test run operation mode, the thermostat will not be switched off by indoor air temperature control
and the operation will continue.
