4.4.5 Optional Functions of Remote Control Switch
(1) Removal of Heating Temperature Calibration
This function is utilized when the temperature settings of the remote control switch and the suction air
temperature of the indoor unit are required to be equal.
In standard heating operation, the suction air temperature is higher than the room temperature,
therefore the suction air temperature is calibrated -4°C.
(Indicated Setting Temperature = Inlet Air Temperature -4°C Return to 0°C)
This is useful when the thermistor at the suction side of an indoor unit is removed and installed in
another place.
The indicated setting temperature and the suction air temperature after removal of heating
temperature calibration are as shown below.
(2) Circulator Function at Heating Thermo-OFF
In case that the fan speed is changed to “LOW” tap at heating Thermo-OFF, there is a case that the
room air is stratified because warm air stagnates near the ceiling. In this case, it is recommended
that the circulator function explained below be utilized.
<Circulator Function>
The function keeps the fan speed at thermo-OFF at the same level as thermo-ON. In this case, air
movement in the room will be kept on the same level as thermo-ON, ensuring a homogenous air
distribution. In the case that an Auto Louver is equipped, this operation will be also held on when the
heating is turned thermo-OFF.
NOTE:
Perceptions of coolness, heat and air flow are subject to personal tastes and behaviors. It is therefore
recommended to discuss this with customers thoroughly and then to set the unit accordingly.
(3) Enforced 3 Minutes Minimum Operation Time of Compressor
When a compressor frequently starts and stops in short intervals, this function should be used to
guard the compressor. By setting this function, the mode of a minimum 3 minutes operation will be
added. (The mode of a minimum 3 minutes stoppage is standard.)
In case of SET-FREE, this function is standard even when setting is not available.
NOTE:
When the safety device is activated or the “ON/OFF” switch is pressed, the compressor is stopped
immediately.
