Functions
Heating
When heating, the hot air rises to the top of the room, resulting in the temperature being lower near the
floor where the occupants are. When controlling by body thermostat sensor only, the unit may therefore be
turned off by the thermostat before the lower part of the room reaches the preset temperature. The
temperature can be controlled so the lower part of the room where the occupants are doesn't become cold
by widening the range in which thermostat sensor in remote controller can be used so that suction
temperature is higher than the preset temperature.
Assuming the preset temperature in the figure above is 24˚C, and the suction temperature has
changed from 18˚C to 28˚C (A → F):
(This example also assumes there are several other air conditioners, the VRV system is off, and that
temperature changes even when the thermostat sensor is off.)
Body thermostat sensor is used for temperatures from 18˚C to 25˚C (A → C).
Remote controller thermostat sensor is used for temperatures from 25˚C to 28˚C (C → E).
And, assuming suction temperature has changed from 28˚C to 18˚C (D → A):
Remote controller thermostat sensor is used for temperatures from 28˚C to 23˚C (D → B).
Body thermostat sensor is used for temperatures from 23˚C to 18˚C (B → A).
