Humidity Control Features
The various humidity control features of the Thermidistat Control are explained
below. They are grouped into 2 sections, humidification and dehumidification.
Instructions on how to select each feature are given at the end of each section.
Humidification
The Thermidistat Control directly connects to a standard 24VAC humidifier to
control humidification in the home. A humidify setpoint between 10 and 46% in
2% increments relative humidity is selected by the homeowner, or all
humidification can be turned off. When humidity in home drops below setpoint,
humidifier will be turned on to raise humidity level. Humidification can only
occur while heating. See Table 2 for reference.

1. Humidify
In normal humidify, humidifier will be on if there is humidity demand
and any heating equipment is on. This will include furnace, heat pump, or
auxiliary heat.
2. Auto Humidify
Thermidistat Control will automatically adjust the humidity setpoint ac-
cording to the outdoor temperature. As the outdoor temperature de-
creases, the humidity setpoint also decreases. Settings ranging from 1 to
9, 1 being the lowest and 9 the highest, will be visible to the homeowner.
