BATTERY LOCATION  
   
   
ELECTRIC HEAT OR SINGLE-STAGE  
         
   
   
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.  
                     
   
HEAT PUMP 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 ELECTRIC/GAS  
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.  
switch   on the back of the thermostat (see fig. 1) and switch it to  
   
   
HYDRONIC (HOT WATER OR STEAM)  
            
   
   
   
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.  
   
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-  
   
ATTACH THERMOSTAT BASE TO WALL  
            
   
      
1. Remove the packing material from the thermostat. Gently RATION MENU, page 4).  
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 7).  
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.

(common   problems)  
   
   
1. Blown fuse or tripped circuit breaker.  
2. Furnace power switch to OFF.  
Replace fuse or reset breaker.  
Turn switch to ON.  
3. Furnace blower compartment door or  
panel loose or not properly installed.  
Replace door panel in proper position to engage  
safety interlock or door switch.

2. SYSTEM Switch not set to HEAT.  
Set SYSTEM Switch to Heat   and raise setpoint  
above room temperature.  
3. Loose connection to thermostat or system.  
Verify thermostat and system wires are securely  
attached.  
4. Furnace Lock-Out Condition. Heat may also  
be intermittent.  
Many furnaces have safety devices that shut the  
system down when a lock-out condition occurs.  
If the heat works intermittently contact the furnace  
manufacturer or local service person for assistance.  
Diagnostic: 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 service person to verify the heating system is  
operating correctly.
