Set up Dehumidification Away Mode
1. Select Allowed at ISU 9180. See Fig. 231.
Fig. 231.
2. Set Fan Control settings. See Fig. 232.
• On: Fan is always on.
• Automatic: Fan runs only when cooling system is on.
• Circulate: Fan runs randomly, about 35% of the time.
Fig. 232.
3. Set temperature and dehumidification settings. See Fig.
234.
• Low Limit Temperature Setting
If the cooling system is used to control humidity while
Dehumidification Away Mode is active, the thermostat
allows the cooling system to lower the indoor air to the
Low Limit Temperature Setting to reach the
Dehumidification Setting at ISU 9200.
• Temperature Setting
The temperature maintained while Dehumidification
Away Mode is active and the desired humidity level is
satisfied.
• Dehumidification Setting
The desired humidity level while Dehumidification
Away Mode is active.

Control Dehumidification Level
1. Press MENU, then scroll to select Dehumidification.
2. Press Auto to use the dehumidifier or cooling system to
maintain your desired humidity level.
3. Press Off to turn off dehumidification.
4. Move the slider bar to the humidity level you prefer, then
press DONE. The dehumidification setting range is
40–80% in 5% increments.
NOTE: When set for A/C with Low Speed Fan or A/C
with High Speed Fan, an overcooling limit can
be set from 0 °F to 3 °F (ISU 9070). The ther-
mostat uses the cooling system to reduce
humidity by lowering the temperature up to 3° F
below the current cool setpoint until the desired
humidity level is reached.
5. Press MORE SETTINGS to review or change settings for
the dehumidifier filter timer.
NOTE: If humidification and dehumidification are setup
to operate in the same system mode (Heat, Cool,
Off) and you are sensing humidity from one loca-
tion, 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 differ-
ent locations using a remote wireless indoor sen-
sor (for example, main level and crawl space), the
thermostat will allow humidification and dehumid-
ification to operate at the same time, and there is
no deadband between humidification and dehu-
midification settings.
