Thermostat-control
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.)
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.
Thermostat-control in Normal Operation
As to VRV system, remote controller thermostat is set to use when shipped from factory.
Normally thermostat differential is set to setting temperature –1°C at cooling, while set to setting temperature +1°C in heating when shipped from factory.
However, the unit can be controlled only by body-thermostat when using 1 group remote controller. For cassette type indoor unit, the unit is controlled with compensation value of –2°C against body-thermostat detection value in heating operation. (Thermostat – differential can be changed from 1°C to 0.5°C with field setting. Refer to page 43 and page 44 for changing.)

Thermostat – control in Dry Operation
In dry operation, control is made based on suction temperature at the time of operation start.
Fan is driven with L flow rate during dry operation, and turned off for a period of 6 minutes during thermostat-off, and then with L flow rate. (In order to prevent humidity from rising in the room during thermostat-off.)
