• It can obtain the humidifying signal linked to the heater
operation of the air conditioners.
• Temperature sensors for the air conditioners are provided as
standard equipment at the intake port of the indoor unit and
two locations of the wired remote controller. The function
selection from the wired remote controller can be used for
switching.
• If the sensor in the intake port of the indoor unit is replaced
