Humidity Control Screen for Humidification in Automatic Mode  
In automatic mode you will receive the optimum  
amount of humidity so that your home and its  
furnishings are protected from the damaging effects  
of excess condensation or low humidity during  
heating season. The thermostat automatically adjusts  
your home’s relative Humidity based on the outdoor  
temperature.  
The humidity setting needs to be set initially to  
meet your home’s conditions. Please follow these  
steps when adjusting your thermostat.  
HUMIDIfICATIon sETPoInT  
HUMIDIfIEr ADJUsTMEnT  
1. Adjust the humidity setting to “3” which is within  
normal range. During the next 24-48 hours it may  
be necessary to adjust the setting for more or less  
humidity, depending on your personal comfort and  
home’s requirements.  
The Humidity Control screen is used to access control for  
both humidification and dehumidification.  
If humidification is installed it can be controlled in two  
modes, automatic or manual.  
2. During the coldest portion of the first heating  
season, minor adjustments may be necessary. This is  
dependent upon your home’s construction.

accurately controlled to meet your needs and should not  
need further adjustment during future heating seasons.

Energy Saving Tip #1:  
If dehumidification is installed the thermostat can  
be configured, through the installer set-up, to control  
dehumidification with either a whole home dehumidifier  
or with the air conditioner (cooling unit).  
your comfort is the best measure of how to adjust  
your setting. When first installed, your dehumidifier  
has to remove all the moisture that is initially in your  
home. The home acts like a sponge so the moisture in  
the materials of your home is at the same level as the  
air. After drying the air, the materials of the home will  
release the moisture back into the air until they are  
again at the same level. As a result, it is not uncommon  
for dehumidification to operate for an extended period  
of time when it is first installed.  
Energy Saving Tip #2:  
Adjust the setting to be as high as is comfortable to  
reduce dehumidification run time – if it feels clammy or  
smells damp or moldy lower the setting. To save energy,  
turn the dehumidifier control OFF when you open your  
windows just as you would with air conditioning.  
If vacating your home for an extended period in the  
summer, set the Relative Humidity at 60% and set  
the cooling setpoint as high as you are comfortable  
setting it to in cooling mode. Consult with appropriate  
professionals regarding the highest temperature that  
is safe for your pets or possessions. This will keep  
the humidity at a controlled level to help prevent mold  
while minimizing the amount of the cooling energy  
used. Vacation hold is a convenient way to adjust the  
dehumidification and cooling setpoint when you will  
be away.  
The thermostat will allow you to set the desired humidity  
(% relative Humidity) level in your home and can be used  
to turn the dehumidification On or Off.  
Use the dehumidification adjustment to set the  
dehumidification setpoint to 60% when first installed.  
Allow dehumidification to run until the initial setpoint  
is reached, before deciding if you want to change the  
humidity setting.  
Raise the setting if you prefer the air to be  
less dry; this will reduce the amount of time that  
dehumidification runs.  
lower the setting if you prefer the air to be  
more dry; this will increase the amount of time that  
dehumidification runs.
