General Functionality ESIE05-032–12 Part 2 – Functional Description312451.8 Using Conditions for Remote Controller ThermostatApplicable 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 sensorcan 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 temperaturecombination in cooling operation:Example Assuming the preset temperature above is 24°C, and the suction temperature has changedfrom 18°C to 30°C (A --> F):(This example also assumes there are several other air conditioners, the VRV system is off, and thattemperature 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).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.
