6.3.3 Description of the optional remote control functions
b1 – Elimination of the heating temperature offset
This function is useful when the thermistor is removed from the suction area of the indoor unit and installed somewhere
else. It is used when the temperature setting displayed on the remote control and the inlet air temperature of the indoor unit
are to be the same.
Settings
Actual temperature control
00 Standard setting. Selected temperature +4 °C increase
01 Offset elimination
02 Selected temperature +4 °C increase
b2 – Forced air circulation function on reaching the set temperature
This function is useful when the air in the room is stratified (hot air accumulates at the ceiling). Air stratification may occur
if LOW has been selected with the heating thermostat off. This function prevents air stratification in the room after stopping
the air conditioning system.
The circulation pump function maintains the fan speed, whether the thermostat is on or off. Hence, the air movement in the
room is kept at the same level to ensure even air distribution.
N O T E
If the indoor unit has an automatic louver, this function also remains active when the heating thermostat is switched
off.
