Control of Indoor Unit Si30-408
28 Basic Information
4. Control of Indoor Unit
4.1 Thermostat-control
4.1.1 Operation Range of Remote Controller Thermostat
Room temperature is controlled by remote controller thermostat side and suction thermostat
(body-thermostat) on indoor unit side.
(However, when remote controller thermostat is set to "Not used " with field setting, the unit can
be controlled only by body-thermostat.)
Note: When the outdoor air (OA) mixed with indoor air is sucked, the room temperature may happen
to be out of the set temperature because the air temperature is out of the area of "operation
range of remote controller thermostat ". In such a case, install the remote controller thermostat
in the room where there is no influence of outdoor air.
