The excess condensation occurs because the indoor relative humidity is higher than what the home can support for the current outdoor temperature.
To adjust the humidity setting, simply rotate the control knob to the desired setting.
Provided the HVAC system fan is operating and the humidification level is lower than the new set point, the manual humidistat will activate the humidifier. ProductSiteLaunchDate : 2022-09-24T01:06:46.083Z RoomType : Living Room UnspscCode : 52141500
