4-1. Control Functions

1. Indoor Air Temprature Control
The thermostat is switched on and off in accordance with
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
The settings at factory shipment during heating operation are as follows:
Wall-Mounted type : 2
Floor Standing type : 0
All other types (4-way types, Concealed types, etc.) : 4
This function acts as the coeffi cient for adjusting differences in temperature caused by the height of the living
space from the fl oor to the ceiling (the temperature at ceiling height is higher) during heating operation.
The setting can be modifi ed between 0

(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) The thermostat will not be switched off by indoor air temperature control and operations will continue during
the test operation mode.
2. Compressor Frequency Control
The frequency of the compressor's inverter is limited by either of the following controls depending on whether the
cooling or heating mode is in operation.
Cooling Mode :
· Indoor air temperature control
· Maximum and minimum frequency control
· Current release control
· Cooling high-load prevention control
· Cooling freeze prevention control
· Discharge temperature control
1) Indoor Air Temperature Control
By the control method, not only the thermostat is switched on and off, as explained above section " 1.
Indoor air Temperature Control ", but also the frequency of the compressor's inverter is controlled in
accordance with
When T is high (not yet reached the temperature set
with the remote controller).
When T is low (approximately +1.0 or less in the
cooling mode or approximately -1.0 or more in the
heating mode).
When the indoor air temperature is rising in the cooling
mode and dropping in the heating mode.
When the indoor air temperature is dropping in the
cooling mode and rising in the heating mode.
* The fl uctuations of the compressor inverter frequency adjustments are calculated taking into account not only
but also-fl uctuations in indoor air temperature.
