4. Select a Geothermal Forced Air Option. For example,
if Geothermal Forced Air is used for both heating and
cooling, select the "Heating and Cooling" option. See
Fig. 172. Other options are "None" (Geothermal
Forced Air is not used) and "Cool Only" (Geothermal
Forced Air is only used for cooling).See Fig. 172.

Humidification

The thermostat reads the indoor humidity level and allows
the user to set a humidification setting with or without
window protection.
The thermostat can be set up to control a humidifier in any
system mode in the Installer Setup (ISU 806). A discharge
air sensor is required to humidify in the cool mode.
If humidification and dehumidification are setup to operate
in the same system mode (Heat, Cool, Off) and you are
sensing humidity from one location, the thermostat will
automatically enforce a 15% deadband between the
humidification and dehumidification settings. The
thermostat will automatically switch between
humidification and dehumidification to maintain the
desired humidity level.
If humidification and dehumidification are setup to operate
in the same system mode (Heat, Cool, Off) and you are
sensing humidity from two different locations using a
remote wireless indoor sensor, the thermostat will allow
humidification and dehumidification to operate at the
same time, and there is no deadband between
humidification and dehumidification settings.
Window Protection
Window Protection limits the amount of humidity to
prevent frost or condensation on windows. Window
Protection (ISU 805) requires an outdoor sensor.
The thermostat prevents frost or condensation on windows
by not allowing the humidifier to run above a certain level.
To prevent frost or condensation, the thermostat may turn
off the humidifier before the humidity setting is reached.
To adjust the Window Protection setting, press MENU,
scroll down and select Window Protection. Window
Protection is set on a scale from 1-10. A setting of "1"
represents poorly insulated windows and a setting of "10"
represents well insulated windows. A lower number
automatically reduces the humidity to help prevent frost or
condensation on your windows. Use a higher number if
indoor air seems too dry. To prevent frost/condensation on
