Thermostat Sensor in Remote Controller SiUS34-801A_b
288 Indoor Unit
Heating
When heating, the hot air rises to the top of the room, resulting in a lower temperature near the
floor where the occupants are. When controlling by return air sensor only, the unit may cycle off
before the lower part of the room reaches the preset temperature. The temperature can be
controlled so that the lower part of the room, where the occupants are, does not get cold. This can
be accomplished by widening the thermostat sensor’s range in the remote controller so that the
return air temperature is higher than the preset temperature.
Ex: When heating
Assuming the preset temperature in the figure above is 75°F, and the return air 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.
Return air 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 return air 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).
Return air sensor is used for temperatures from 73°F to 64°F (B
