REMOVING OLD THERMOSTAT
To prevent electrical shock and/or equipment damage,
disconnect electrical power to the system at the main fuse
or circuit breaker until installation is complete.
Before removing wires from old thermostat's switching subbase,
label each wire with the terminal designation it was removed
from. Some models also include an adaptor plate to cover
unpainted surfaces. Thermostat wires pass through the adaptor
plate center opening.
1. Remove Old Thermostat: A standard heat/cool thermostat
consists of three basic parts:
a. The cover, which may be either a snap-on or hinge type.
b. The base, which is removed by loosening all captive screws.
c. The switching subbase, which is removed by unscrewing the
mounting screws that hold it on the wall or adaptor plate.
Make a note here
the old thermostat for future reference and use in step 5.
The heat anticipator pointer, if adjustable, will be set at one of a
series of numbers representing the current rating of the primary
control in your furnace. The number will be one of the following:
.2, .4, .8, etc. or 0.2, 0.4, 0.8, etc.
If no heat anticipator/indication is showing, do not be concerned;
move on to the next step.
