Loosen the terminal screws and slip each wire  
beneath its matching terminal. The shape of the  
terminals permit insertion of straight or wraparound  
connections. See Fig. 5. Tighten the terminals.  
Fig. 3. Mounting wallplate to wall.  
Remove the wallplate from the wall and drill two 3/16-  
in. holes in the wall (if drywall). For firmer wall material  
such as plaster or wood, drill 7/32-in. holes. Gently tap  
provided anchors into the drilled holes until flush with  
the wall.  
Reposition the wallplate, pulling wires through the  
wiring opening. Loosely insert the mounting screws  
into the holes.

All wiring must comply with local electrical codes and  
ordinances. If unsure about household wiring  
procedures, call your local heating and air conditioning  
contractor.

Plug the hole in the wall with insulation to help prevent  
drafts from adversely affecting thermostat operation.  
Refer to the labels you placed on wires when you  
removed your old thermostat.  
The CT3451 Thermostat is powered with 3AA alkaline  
batteries and is adaptable to most 18 to 30 Vac heating-  
cooling systems. Refer to Fig. 6 through 10 for typical  
system wiring diagrams.  
Match the letter of your old thermostat wire with the  
terminal of the corresponding letter on your new  
thermostat. Refer to Fig. 4.

position. This is the correct setting for most systems. If  
you have an electric heat system, set the switch to the E  
(electric) position. The E setting allows the fan to turn on

NOTE: The thermostat shows a “bAtLo” message on  
the digital display to alert the homeowner one to  
two months before the batteries run out com-  
pletely.  
6 MOUNT THERMOSTAT TO

IMPORTANT  
Homeowner should replace the batteries once a  
year to prevent leakage and/or the heating/cool-  
ing system from shutting down due to lack of  
battery power in the thermostat.

Display shows flashing or steady “bAtLo.”  
The batteries are low; replace them as soon as possible.  
Temperature change occurs at the wrong

Heating does not come on.  
Check that the System switch is set to Heat.  
Check the system fuse or circuit breaker and replace or reset, if  
necessary.  
Check for correct wiring and good connections.  
If display is blank or displays “bAtLo,” install fresh batteries.  
Allow time for the furnace to heat up and the fan to come on  
before checking for heat at the register.  
If the temperature setting is higher than the current room
