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.
1. Remove Old Thermostat: A standard heat thermostat consists
of two basic parts:
a. The cover, which may be either a snap-on or hinge type.
b. The base, which is removed by unscrewing the mounting
screws that hold it on the wall or adaptor plate.
Make a note here
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.
