SiUS30-604 Outline of Control (Indoor Unit)
Function 87
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.

Ex: When heating
Assuming the preset temperature in the figure above is 75°F, and the suction temperature
has changed from 64°F to 82°F (A
→
D):
(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 64°F to 77°F (A
→
C).
Remote controller thermostat sensor is used for temperatures from 77°F to 82°F (C
→
D).
And, assuming suction temperature has changed from 82°F to 64°F (D
→
A):
Remote controller thermostat sensor is used for temperatures from 82°F to 73°F (D
→
B).
Body thermostat sensor is used for temperatures from 73°F to 64°F (B
→
A).
