POWER THE THERMOSTAT
You can choose from three methods to power the thermostat:
• Batteries only (AAA alkaline).
• 24 Vac direct connection only.
• 24 Vac direct connection with battery backup (AAA alkaline).
Wiring 24 Vac Common
• Single-Transformer System—Connect the common side of
the transformer to the C screw terminal of the thermostat
wallplate. Leave the metal jumper wire in place between Rc
and R.
• Two-Transformer System—Connect the common side of
the cooling transformer to the C screw terminal of the
thermostat wallplate. Remove the metal jumper wire
between Rc and R.
Installing Batteries
1.
Install three AAA alkaline batteries on the back of the
thermostat as marked. See Fig. 23.
BATTERIES (3)
Locate and Mount C7089U Outdoor
Temperature Sensor (Optional)
Mount the sensor where (see Fig. 25):
• cannot tamper with settings.
• there is good air circulation.
• it can measure true outdoor ambient temperature.
• surface is flat.
• wire distance between C7089U and thermostat is less than
200 feet.
Do not mount the sensor:
• in direct sunlight.
• where hot or cold air blows on the sensor. Discharge line
from an outdoor compressor unit, vent or fan causes
inaccurate temperature readings.
• where snow, ice or debris can cover it.
Use the following steps to mount the sensor:
1. Remove the sensor from the mounting clip.
2. Mark the area on the location selected for mounting the
sensor mounting clip.
3. Mount the clip.

— Pressing a locked key prompts the screen to indicate
SCREEN LOCKED for five to seven seconds.
— Pressing an unlocked key with SCREEN LOCKED active
removes SCREEN LOCKED from the display.
PARTIAL LOCKOUT 1
This mode locks all keys except HOLIDAY, OVERRIDE, and
temperature Up/Down arrows:
— User can change the temperature setpoint, but cannot
change schedule settings.
— The temporary temperature change lasts until next
scheduled period. The screen displays that time.
— User can change the temperature setpoint, but cannot
change schedule settings.
— Pressing HOLIDAY sets the temperature to the Unoccupied
setting for the selected period of time. The next Occupied
period switches back to the program settings.
— Pressing OVERRIDE sets the temperature to the Occupied

— Pressing OVERRIDE sets the temperature to the Occupied
setting for the selected period of time. The next Unoccupied
period switches back to the program settings.
— To cancel the temperature override and follow the
programmed schedule, press CANCEL.
— To unlock the screen, see Advanced Settings section.
Temperature Recovery
The thermostat is equipped with a feature to eliminate
guesswork when setting a schedule. That is, the user need not
know the amount of time for the HVAC system to bring the
space to temperature (without overshoot) prior to the
scheduled time.The thermostat manages that automatically.
Simply set the program schedule to the desired time to have
the space at comfort temperature. In addition, program the
temperature to this comfort temperature. The thermostat
activates the heating or cooling at the proper time to reach the
scheduled temperature at the scheduled time.
NOTE: The setpoint changes gradually to use economical
stages and avoid overshoot.
63-2625—04
20
For example—the space will be occupied at 8:00 AM and the
desired temperature is 70°F. Set the OCC 1 period for 8:00 AM
and 70°F. The thermostat turns on the heat prior to 8:00 AM to
raise the temperature to 70°F by 8:00 AM.
The thermostat provides an alert that the heating or cooling
system is coming on before a scheduled time by displaying
“Recovery” on the screen.
Minimum-Off Timer Compressor Protection
The thermostat has an adjustable Minimum-Off Timer that can
be set from zero to five minutes (Factory Setting—five
minutes). The Minimum-Off Timer can be bypassed through
the Installer System Test or it can be bypassed permanently by
setting the Minimum-Off Timer to 0 minutes in the Installer
Setup. The Minimum-Off Timer is activated after the
compressor turns off:
— If the thermostat is system powered (common wire), the
Minimum-Off Timer is also activated upon initial startup and
after power interruptions.
— If there is a call for cooling or heating during the MinimumOff Time, the thermostat displays “Wait.”
— When the Minimum Off Timer expires, “Cool On” or “Heat
On” (heat pumps only)” appears solidly in the display and
the compressor and fan turn on.
