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:
Example: Assuming the preset temperature 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).
