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 of the anticipator setting on 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.

This thermostat is easy to operate. After power is turned on, use the system switch to
select either heating or cooling, or to turn the heating/cooling system off. Use the fan
switch to control fan operation. When the fan switch is in the AUTOAUTO

AUTO position, the fan will
cycle with the heating or cooling system (the fan will not run if the system switch is in the
