4.4 Remote Controller Thermostat
Applicable
The remote control thermostat is only available in wired remote controllers, BRC1C62, BRC2C51, BRC1D61.
Method
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).
Condition The remote controller thermostat is not used when...
1 The remote controller thermostat malfunctions.
2 Group control is used.
3 The set temperature / air suction temperature combination is out of range. (See below graph)
