*1 While the heater is on, the fan will operate at high speed regardless of the fan setting on the remote controller
*2 Heater will not operate during all error modes. Heater will only operate during a communication error between indoor unit and outdoor unit
Note: When CN4Y is used the fan is off when CN24 is energized which is only for use with supplemental heat that is not in the duct.
By setting the Mode No. 23 in the Function Table in section 9-1, the following patterns of fan control will become possible.
Fan control patterns
* If a heater is installed in the duct, do not use Panel heater connector. By doing so, the fan will turn off
when the heater is on, which may result in fire.
*1 While the heater is on, the fan will operate at high speed regardless of the fan setting on the remote controller.
*2 While the heater output is on in the Function Ta ble in section 9-1, the heater will be ON except when the unit is in
