2-stage Furnaces
» Refer to the How to Wire a Humidifier to a Daikin Furnace section
under Installing the
Daikin One+ smart thermostat section for
details on wiring a humidifier directly to a furnace.
» For 2-Stage furnaces, the Daikin One+ supports ‘humidifier relay’
settings with the following options:
– ON: The humidifier is turned on when heat demand and
humidification demand are present.
– OFF: The humidifier remains off (the relay never closes).
» For modulating furnaces, the humidifier is turned ON whenever heat
demand and humidification demand are present.
