HUMIDITY CONTROL

This thermostat can control the relative

humidity (RH) in your home when you

have an additional humidifier and/or

dehumidifier installed. Dehumidification can be achieved one of two ways, either

with a whole-home dehumidifier or with your air conditioning equipment

1

See page 26 for details. If a humidifier is installed, it can be controlled in one of

two modes, Automatic or Manual These

settings are configured by your installer.

Automatic Humidifier
In automatic mode, you will receive an optimal amount of humidity so that your home and its furnishings are protected from the damaging effects of excessively high or low humidity during the heating season The thermostat automatically adjusts your home’s RH based on the outdoor temperature This temperature is measured by a sensor attached outside your home

The humidity setting needs to be set initially to meet your home’s conditions Please follow these steps when adjusting your control

1. Touch Humidity Control to open the Humidity Control Select screen

2. Touch Humidifier to open the Humidifier

2

Control screen

3. The normal humidity range is 3-5 Use setting 3 initially

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

During the coldest portion of your first
heating season, minor adjustments may be necessary to prevent window condensation This will depend on your home’s construction

The relative humidity in your home will then be accurately controlled to meet your needs and should not need further adjustment during future heating seasons

3

25

INDOOR AIR QUALITY FUNCTIONS

HUMIDITY CONTROL (continued)
Manual Humidifier
In manual mode, it is important to anticipate a drop in outdoor temperature and to reduce the setting accordingly to avoid excessive condensation Use the table on the right side of the Humidifier Control screen to determine the proper RH setting
4. Touch the or arrows to adjust the RH accordingly, and then touch Done when finished.
Dehumidification
The thermostat will allow you to set the desired RH level in your home and can be used to turn dehumidification on or off.
5. Touch the arrow to increase the amount of humidity the dehumidifier will allow. The air will be less dry and the dehumidifier will run less.
6. Touch the arrow to decrease the amount of humidity the dehumidifier will allow. The air will be less humid and the dehumidifier may run more
If dehumidification is done with the air conditioner, the thermostat will cool up to 3°F beyond the cooling setpoint for dehumidification.
NOTE: Overcooling may not be sufficient to meet the dehumidification setpoint.
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
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.

4
5 6
Energy Saving Tip #1: 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. Set the Dehumidifier Control to Off when you open your windows Energy Saving Tip #2: If your home will be unoccupied for an extended period during the summer, set the Dehumidifier Control setpoint to 60% RH and your cooling setpoint as high as you feel comfortable. Consult 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 while you are away.
