Using Conditions for Remote Controller Thermostat

Applicable The remote control thermostat is only available in wired remote controls.
Method The remote control sensor is standard disabled for sky-air units. The use of the remote control
sensor can be enabled by changing field setting 10(20)-2-02 to 10(20)-2-01.
Conditions The table below contains the condition in which the remote control thermostat is not used:

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 controller 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).
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).
