And assuming suction temperature has changed from 30°C to 18°C (F --> A):
Body thermostat sensor is used for temperatures from 30°C to 25°C (F --> D).
Remote controller thermostat sensor is used for temperatures from 25°C to 21°C (D --> B).
Body thermostat sensor is used for temperatures from 21°C to 18°C (B --> A).
Heating The diagram below shows the operation range of the set temperature / air suction temperature
combination in heating operation:
Preset temperature
(Ts)
Example Assuming the preset temperature above is 24°C, and the suction temperature has changed
from 18°C to 28°C (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 18°C to 25°C (A --> C).
Remote controller thermostat sensor is used for temperatures from 25°C to 28°C (C --> D).
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).
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.
