If the indoor heater turned OFF from ON during heating operation, the fan will keep operating for
further period of time in order to cool the heater.
Detail
∗
1. When the heater is ON, the airflow rate of the fan will be whichever is the largest between the
CFM dictated by the heater's own capacity, or the fan tap CFM determined by other controls.
∗
2. Fan residual operation will continue, even if the indoor unit is turned off with the remote
controller operation button.
9.15 Interlocked with External Equipment (FXTQ-TA Models)
9.15.1 Air Purifier (UV lamp)
When an air purifier is connected onsite, the fan is operated with the airflow rate set of the remote
controller or with the H tap.
∗
1. External input ON is an input signal to the X1M-AIR CLEANER terminal on the PCB.
∗
2. Field setting 14(24)-4. Refer to page 131.
9.15.2 Humidifier
When a humidifier is connected onsite, the fan operates with the airflow rate set of the remote
controller or with the H tap.
∗
1. External input ON is an input signal to the X1M-HUMIDIFIER terminal on the PCB.
∗
2. Field setting 14(24)-4. Refer to page 131.
