nVentilating fan control from remote controller

[Function]

The start/stop operation can be operated from the wired remote controller when air to air heat exchanger or ventilating fan is installed in the system.

The fan can be operated even if the indoor unit is not operating.

Use a fan which can receive the no-voltage A contact as an outside input signal.

In a group control, the units are collectively operated and they can not be individually operated.
