ABOUT THE IQ DRIVE THERMOSTAT

• The iQ Drive Thermostat is a wall mounted controller
that accurately maintains room temperature by
controlling conventional or iQ Drive compatible
components in a heating and air conditioning
system. Easy-to-use operating modes activate
cooling equipment (heat pump or air conditioner)
during warm seasons and heating equipment (heat
pump, electric heater, gas furnace or heat pump/
electric heat combination) when the temperature
gets colder. For operating mode setup instructions,
See page 6.
• The iQ Drive Thermostat serves as the primary
controller for homes equipped with the iQ Zone
system. In such systems there will be a separate
zone thermostat in each of the zones set up, in
addition to this controller. See the iQ Zone System
Zone Thermostat User's Manual for information on
how to operate the local zone thermostats. See the
Zone Control section (page 13) for a description
of operation and features which only apply to iQ
Zone systems.
• Dehumidifi cation mode quickly removes moisture
from the air and regulates humidity levels
throughout the home. Control output for optional
humidifi er is also provided. See page 12.
• The blue backlight feature makes viewing the
screen easier at night or in poorly lit rooms. The
backlight turns on for a certain amount of time
when any one of the five buttons is pressed.
The duration that the backlight stays on can be
programmed for 30, 60, 90, 120 seconds, or ON.
See page 5.

when service is needed.
