Example<br />
Assuming the preset temperature above is 24°C, and the suction temperature has changed from 18°C to 28°C<br />
(A --> D):<br />
(This example also assumes there are several other air conditioners, the VRV system is off, and that temperature<br />
changes even when the thermostat sensor is off.)<br />
Body thermostat sensor is used for temperatures from 18°C to 25°C (A --> C).<br />
Remote controller thermostat sensor is used for temperatures from 25°C to 28°C (C --> D).<br />
And assuming suction temperature has changed from 28°C to 18°C (D --> A):<br />
Remote controller thermostat sensor is used for temperatures from 28°C to 23°C (D --> B).<br />
Body thermostat sensor is used for temperatures from 23°C to 18°C (B --> A).<br />
TH1=Ts+12≤33˚C<br />
Differential<br />
When heating, the hot air rises to the top of the room, resulting in the temperature being lower near the floor where the<br />
occupants are.When controlling by body thermostat sensor only, the unit may therefore be turned off by the thermostat<br />
before the lower part of the room reaches the preset temperature. The temperature can be controlled so the lower part of<br />
the room where the occupants are doesn’t become cold by widening the range in which thermostat sensor in remote<br />
controller can be used so that suction temperature is higher than the preset temperature.<br />
