Room temperature detection temperature compensation during heating

With the standard specification, the compressor is turned ON/OFF with the thermostat setting temperature. When the thermostat
is likely to turn OFF earlier because the unit is installed at the ceiling where warm air tends to accumulate, the setting can be
changed with the wired remote controller indoor unit function "
at one of the setting temperature +3, +2 or +1°C in order to improve the feeling of heating. The setting temperature, however,
has the upper limit of 30°C.

Return air temperature compensation

This is the function to compensate the deviation between the detection temperature by the return air temperature thermistor and
the measured temperature after installing the unit.
1) It is adjustable in the unit of 0.5°C with the wired remote controller indoor unit function "RETURN AIR TEMP".
• +1.0°C, +1.5°C, +2.0°C
2) Compensated temperature is transmitted to the remote controller and the compressor to control them.
Note (1) The detection temperature compensation is effective on the indoor unit thermistor only.
