1
WIRING AND MOUNTING  
Disconnect power supply before making wiring connec-  
tions to prevent electrical shock and equipment damage.  
All wiring must comply with applicable electrical codes,  
ordinances and regulations. Use copper wire only. Make  
sure that thermostat electrical rating is sufficient for current  
requirements of controlled equipment, and that listed volt-  
age matches power supply.  
condition.  
2
. Check the ratings given in the instructions and on  
the product to make sure the product is suitable for your  
application.  
3
. Installer must be a trained, experienced service  
technician.  
4. After installation is complete, check out product op-  
eration as provided in these instructions.  
T451A/T651A THERMOSTATS (Fig. 3)  
T451A/T651A Thermostats mount vertically on a 2 x 4  
in. or 4 x 4 in. junction box. See Fig. 3. Use 2 x 4 in. cover  
plate with 4 x 4 in. junction. For horizontal mounting, the  
appropriate horizontal faceplate is required. Horizontal  
with thermometer and horizontal blank faceplates are  
packaged with the T651A2028 SUPER TRADELINE  
model. For additional faceplates or T451 applications, see  
Accessories. When replacing old style T451A/T651A, use  
a wallplate to cover previous wall marks. This wallplate is  
packaged with the T651A2028 SUPER TRADELINE  
model. For T451 applications, see Accessories.  
CAUTION  
!
Disconnect power supply before making wiring  
connections to prevent electrical shock and equip-  
ment damage. Use copper wire only.  
LOCATION  
Select the same location as control to be replaced, or  
select a new location about 5 ft. [1.5 m] above the floor, on  
an inside wall where there is good air circulation at average  
room temperature.
