FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY  
BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE  
PERSONAL INJURY AND/OR PROPERTY DAMAGE.  
DESCRIPTION  
This wall-mounted, low voltage thermostat maintains  
room temperature by controlling the operation of heating  
and cooling systems. The user may program up to four  
time/temperature settings per 24 hour period. The ther-  
mostatstoresindependentheatingandcoolingprograms  
for each day of the week. The thermostat will store both  
heating and cooling programs simultaneously. Three  
"AA" Energizer® batteries will maintain the stored pro-  
gram for approximately one year, if incoming power  
should fail. If power failure is extensive and the program  
is lost, after power restoration, the thermostat will auto-  
maticallymaintainafactorypreprogrammedheatingtem-  
perature of 64°F or a cooling temperature of 82°F.

1. Remove the packing material from the thermostat.  
Place the fingers of one hand on the center top and  
bottom portion of the thermostat. Grasp the subbase  
in the other hand on the top and bottom center, and  
gently pull straight out (see Fig. 2). The thermostat  
has pin and socket connectors. Forcing or prying on  
the thermostat will cause damage to the unit.
