system
In the case of the ceiling chamber system
(duct is not installed at indoor unit inlet
side and room air is sucked into the indoor
unit through the inside of the ceiling), the
thermistor inside the indoor unit may not
correctly detect the room temperature.
Heating operation: Room is not heated
because the indoor unit is easily turned off by
the thermostat.
Cooling operation: Room is too cold because
the indoor unit is difficult to turn off by the
thermostat.

thermistor with a Remote
sensor unit (optional
parts) and install the
sensor where the room
temperature can be
correctly detected
