REPLACE BATTERIES WHEN
INDICATOR APPEARS
N O T E
When replacing batteries, you have
approximately 1 minute before programs are lost.
N O T E
If you have an electric system and the blower does not operate after
installation, find the electric/gas heat selector on the back of the body.
Move the selector to the ELEC position.
WARNING: Use Energizer ® or DURACELL ® Alkaline Batteries Only.
INSTALLING BATTERIES
The Unit requires batteries to operate your furnace
and retain its programming in memory. Replace
the batteries when the REPLACE indicator
appears in the display or at least once a year.
The Unit alternately displays the current time and the room temperature.
It also displays the day of the week and the currently active program
period that is controlling the temperature: MORN, DAY, EVE, or NIght. The
set point temperature will appear in the right side of the display. In the
winter, set the system switch to HEAT to control your heating system. In
the summer, set the switch to COOL to control your air conditioner. In
spring and fall or when windows are open, you can set the system switch
OFF. Setting the FAN switch to AUTO automatically runs your system’s
fan during heating and cooling. Setting the FAN switch to ON runs your
system’s fan continuously even without heating or cooling.
N O T E
The FAN switch works only if your system
provides a wire for the Unit’s “G” terminal.
OPERATION
This thermostat is “armchair programmable” You can make any
program or setting changes with the thermostat body off or on the
wall thermostat base.
1. Remove fresh batteries from their carton.
2. Remove body of thermostat as described at bottom of first column.
3. Remove the battery clip and batteries.
4. Install two new Energizer
® or DURACELL ® "AA" size alkaline
batteries in the battery compartment. Observe the polarity marking
shown in the clip.
5.Place body back on the wall. Hook the bottom of the body onto the
base, swing the body up, and snap the body onto the base.
Installation is now complete. Be sure to turn the power back on to your
heating and /or air conditioning system. If this is the first time you are
installing batteries, the thermostat will display “SUN 12:00 AM”. Within
90 seconds the thermostat will begin to display the room temperature
alternately with the time. To correct the display, see “Setting the TIME
and DAY,” after you set the programs.
