1. Shut off electricity at the main fuse box until installation is  
complete. Ensure that electrical power is disconnected.  
2. Remove the front cover of the old thermostat. With wires  
still attached, remove wall plate from the wall. If the old  
thermostat has a wall mounting plate, remove the thermo-  
stat and the wall mounting plate as an assembly.  
3. Identify each wire attached to the old thermostat using  
the labels enclosed with the new thermostat.  
4. Disconnect the wires from old thermostat one at a time. DO  
NOT LET WIRES FALL BACK INTO THE WALL.

Mercury must not be discarded in household trash. When the  
unit  this  product  is  replacing  is  to  be  discarded,  place  in  a  
suitable container and return to White-Rodgers at 9797 Reavis  
Road, St. Louis, MO, 63123-5398 for proper disposal.  
BATTERY LOCATION  
2 "AA" alkaline batteries are included in the thermostat at the  
factory with a battery tag to prevent power drainage. You must  
remove the battery tag to engage the batteries.  
ELECTRIC HEAT SYSTEMS  
This thermostat is configured from the factory to operate a heat/  
cool, fossil fuel (gas, oil, etc.), forced air system. It is configured  
correctly for any system that DOES NOT require the thermostat  
to energize the fan on a call for heat. If your system is an electric  
heat or heat-pump system that REQUIRES the thermostat to  
turn on the fan on a call for heat, locate the GAS/ELECTRIC  
switch on the thermostat base (see fig. 1) and switch it to the  
ELECTRIC position. This will allow the thermostat to energize  
the fan immediately on a call for heat. If you are unsure if the  
heating/cooling system requires the thermostat to control the  
fan,  contact  a  qualified  heating  and  air  conditioning  service  
person.  
If  BATT  is  displayed,  the  batteries  are  low  and  should  be  
replaced  with  fresh  "AA"  Energizer®  alkaline  batteries.  To  
replace batteries, install the batteries along the top of the base  
(see Fig. 1). The batteries must be installed with the positive (+)  
end to the left.  
HYDRONIC (HOT WATER OR STEAM)  
HEATING SYSTEMS  
This  thermostat  is  set  to  operate  properly  with  a  forced-air  
heating  system.  If  you  have  a  hydronic  heating  system  (a  
system that heats with hot water or steam), you must set the  
thermostat to operate properly with your system. Change the  
second option in the configuration menu to SL (see CONFIGU-  
RATION MENU, page 4).  
ATTACH THERMOSTAT BASE TO WALL  
1. Remove the packing material from the thermostat. Gently  
pull the cover straight off the base. Forcing or prying on the  
thermostat will cause damage to the unit. If necessary, move  
the electric heat switch (see ELECTRIC HEAT SYSTEMS,  
above).  
CHECK THERMOSTAT OPERATION  
If  at  any  time  during  testing  your  system  does  not  operate  
properly, contact a qualified service person.  
2. Connect  wires  beneath  terminal  screws  on  base  using  
appropriate wiring schematic (see figs. 2 through 4).  
Turn on power to the system.  
3. Place  base  over  hole  in  wall  and  mark  mounting  hole  
locations on wall using base as a template.  
Fan Operation  
4. Move base out of the way. Drill mounting holes.  
If your system does not have a G terminal connection, skip to  
Heating System.  
5. Fasten base loosely to wall, as shown in fig. 1, using two  
mounting  screws.  Place  a  level  against  bottom  of  base,  
adjust until level, and then tighten screws. (Leveling is for  
appearance only and will not affect thermostat operation.) If  
you are using existing mounting holes, or if holes drilled are  
too large and do not allow you to tighten base snugly, use  
plastic screw anchors to secure subbase.  
1. Move fan switch to ON position. The blower should begin  
to operate.  
2. Move fan switch to AUTO position. The blower should  
stop immediately.  
6. Push excess wire into wall and plug hole with a fire-resistant

2) Select  FA or SL (Fast or Slow) Heating Cycle Rate - The  
FA setting is frequently used for gas, oil or electric heat. The  
SL setting produces a longer heating cycle which is nor-  
mally  for  hot  water  or  steam  (hydronic)  systems.  Both  
settings  produce  very  accurate  temperature  control  and  
can  be  set  to  your  personal  preference.  FA  cycles  the  
system just under 1°F and the SL setting cycles at approxi-  
mately 1.5°F.  
3) Select Display Backlight (d-L OFF or ON) - The display  
backlight improves display contrast in low lighting condi-  
tions. Selecting backlight ON will keep the light on for a  
short period of time after any key is pressed. Selecting OFF  
will keep the light off.  
OPERATING FEATURES  
Now  that  you  are  familiar  with  the  thermostat  buttons  and  
display, read the following information to learn about the many  
features of the thermostat.  
 SIMULTANEOUS  HEATING/COOLING  SETPOINT  
STORAGE — You can enter both your heating and cooling  
setpoints at the same time. There is no need to change the  
thermostat at the beginning of each season.  
 CONFIGURATION  MENU   Allows  you  to  customize  
certain thermostat options.  
4) Select filter replacement run time - The thermostat will  
display FILTER after the selected time of operation. This is  
a reminder to change or clean your air filter. This time can  
be set from 0 to 1950 hours in 50 hour increments. A  
selection of 000 will cancel this feature. When FIL-  
SETTING THE THERMOSTAT  
This thermostat is very easy to operate. Set the SYSTEM switch  
to  either  HEAT  or  COOL  then  press  
  or  
  until  the  
temperature you want to maintain is shown on the right side of  
the display. If you want to turn the system off, just move the  
SYSTEM switch to OFF.  
TER is displayed, you can clear it by pressing    
 and  
  at  the  same  time.  This  resets  the  timer  and  starts  
counting the hours until the next filter change.  
5) Select Compressor Lockout (LOC OFF or ON) - Select-  
ing LOC ON will cause the thermostat to wait 5 minutes  
before turning on the compressor if the heating and cooling  
system loses power. It will also wait 5 minutes minimum  
between cooling cycles. This is intended to help protect the  
compressor from short cycling. Some newer compressors  
already have a time delay built in and do not require this  
feature. Your compressor manufacturer can tell you if the  
feature  is  already  present  in  their  system.    When  the  
compressor time delay occurs it will flash the (snowflake  
icon) for about five minutes then turn on the compressor.  
The  FAN  switch  controls  the  fan  operation.  When  the  FAN  
switch is set to AUTO, the fan will cycle with the furnace or air  
conditioner. When the FAN switch is set to ON, the fan will run  
continuously, regardless of SYSTEM switch position.  
TROUBLESHOOTING  
Reset Operation  
If a voltage spike or static discharge blanks out the display or  
causes erratic thermostat operation you can reset the thermo-  
stat by pressing  
,  
 and move the SYSTEM switch from  
6) Select Temperature Display Adjustment (4 LO to 4 HI)  
-  Allows  you  to  adjust  the  room  temperature  display    
higher or lower. Your thermostat was accurately calibrated  
at the factory but you have the option to change the display  
temperature to match your previous thermostat.  
OFF to HEAT at the same time. This also resets the factory  
defaults to the configuration menu. If the thermostat has  
power,  has  been  reset  and  still  does  not  function  correctly  
contact your heating/cooling service person or place of pur-  
chase.  
7) Select Temperature DIsplay (°F or °C)  - Changes the  
display readout to Celsius or Fahrenheit as required.  
Batteries  
8) Select Stage Fast (ON or OFF) - When selected ON, the  
second stage starts as soon as the setpoint temperature is  
manually raised 3°F in heat or lowered 3°F in cool from  
room temperature. When selected OFF, the second stage  
will delay approximately 15 minutes before starting.  
For optimum performance, we recommend replacing batteries  
once a year with fresh "AA" Energizer® alkaline batteries.

If the heat works intermittently contact the furnace  
manufacturer or local service person for assistance.  
Diagonistic: Set System Switch to Heat and raise  
the setpoint above room temperature. Within a few  
seconds the thermostat should make a soft click  
sound. This sound usually indicates the thermostat  
is operating properly. If the thermostat  does not  
click, try the reset operation listed above. If the  
thermostat does not click after being reset contact  
your heating and cooling service person or place  
of purchase for a replacement. If the thermostat  
clicks, contact the furnace manufacturer or a
