THERMOSTAT FEATURES

REMOVING OLD THERMOSTAT

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 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.

If no heat anticipator/indication is showing, do not be concerned;

move on to the next step.

What to do if my White Rodgers Thermostat has no heat?

  If your White Rodgers Thermostat isn't producing heat, there are several potential causes: * A blown fuse or tripped circuit breaker: Replace the fuse or reset the breaker. * The furnace power switch is OFF: Turn the switch to ON. * The furnace blower compartment door or panel is loose: Replace the door panel in the proper position. * The pilot light is not lit: Re-light the pilot. * There is a loose connection to the thermostat or system: Verify the thermostat and system wires are securely attached. * The thermostat or heating system requires replacement or service: Have a qualified service person check the system. If the heating system is capable of operation and the no heat condition persists, replace the thermostat.
