Operation Range of Remote Controller Temperature
Sensor
Room temperature is controlled by the remote controller temperature sensor and return-air
temperature sensor (unit-mounted temperature sensor) on the indoor unit. When the remote
controller temperature sensor is set to
Not Used
in a field setting, the unit can be controlled only by
unit mounted temperature sensor (or remote sensor).
Note:
Cooling
When between the room temperature and the setpoint temperature, fine adjustment control
can be achieved using the unit-mounted temperature sensor.
.
If the return-air temperature is close
to the set-point temperature, the sensor mounted in the remote controller in the occupied space is
used.
Ex: When cooling
(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.)
Unit-mounted temperature sensor is used for temperatures from 64°F to 73°F (A
→
C).
Remote controller thermostat sensor is used for temperatures from 73°F to 81°F (C
→
E).
Unit-mounted temperature sensor is used for temperatures from 81°F to 86°F (E
→
F).
And, assuming return-air temperature has changed from 86°F to 64°F (F
→
A):
Unit-mounted temperature sensor is used for temperatures from 86°F to 77°F (F
→
D).
Remote controller thermostat sensor is used for temperatures from 77°F to 70°F (D
→
B).
Unit-mounted temperature sensor is used for temperatures from 70°F to 64°F (B
→
A).
NOTE:
When outdoor air (OA) and indoor return air are mixed, the room temperature may differ from the
set-point temperature because the air temperature is out of the area of
operation range of the remote con-
troller temperature sensor
. In this event, install the remote sensor (KRCS01-1) in the room where there is
no influence of outdoor air.
