Humidification
The thermostat reads the indoor humidity level and allows the user to set a
humidification setting with or without window protection.
Window Protection
Window Protection limits the amount of humidity to prevent frost or condensa-
tion on windows. Window Protection (ISU 8050) requires an outdoor sensor.
The maximum humidity level that is allowed ("Window Limit") is displayed on the
Humidification Settings screen. The thermostat prevents frost or condensation
on windows by not allowing the humidity to go above the Window Limit when it
is controlling the humidifier. This helps inform the user as to why their humidity
setting might not be reached at times. The
Window Limit is based on the current outdoor
temperature and the user's window protection
setting.
If Window Protection is turned Off, the ther-
mostat controls the humidity level to the
user's desired humidity setting. Frost or con-
densation may appear on windows.
Dehumidification - Residential
The thermostat reads the indoor humidity level and allows the user to set a dehu-
midification setting.
When set up for dehumidification using the cooling system, an overcooling limit
can be set from 0 F to 3 F (ISU 9070). The thermostat 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.
