Cooling The diagram below shows the operation range of the set temperature / air suction temperature
combination in cooling operation:
Example: Assuming the preset temperature above is 24°C, and the suction temperature has
changed from 18°C to 30°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 23°C (A --> C).
remote control thermostat sensor is used for temperatures from 23°C to 27°C (C --> E).
Body thermostat sensor is used for temperatures from 27°C to 30°C (E --> F).
