REMOVING OLD THERMOSTAT
!
To prevent electrical shock and/or equipment damage, disconnect electri-
cal 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/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
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.

REMOVING OLD THERMOSTAT (cont'd)
If no heat anticipator/indication is showing, do not be concerned; move on to the
next step.
ATTENTION! This product does not contain mercury. However, this product may
replace a unit which contains mercury.
Do not open mercury cells. If a cell becomes damaged, do not touch any spilled
mercury. Wearing non-absorbent gloves, take up the spilled mercury and place into
a container which can be sealed. If a cell becomes damaged, the unit should be
discarded.
Mercury must not be discarded in household trash. When the unit this product is
replacing is to be discarded, place in a suitable container and return to White-Rodg-
ers at 2895 Harrison St., Batesville, AR 72501 for proper disposal.

MOUNTING AND WIRING
Do not use on circuits exceeding specified voltage. Higher voltage will
damage control and could cause shock or fire hazard.
Do not short out terminals on gas valve or primary control to test. Short or
incorrect wiring will damage thermostat and could cause personal injury
and/or property damage.
Thermostat installation and all components of the system shall conform to
Class II circuits per the NEC code.
A. Remove base from subbase: Loosen the screws on the base and remove.
B. Mount switching subbase: Use the screws provided to mount the subbase or
wallplate to wall (see Fig. 1).
C. Attach wires to appropriate terminals:
• For two wire systems (Heat Only or Cool Only). Replace subbase with wall-
plate. If you have a two-wire Heat Only system, attach one wire to R and one to
wire W. If you have a two-wire Cool Only system, attach one wire to R and one
to wire to Y. Tighten any unused terminals securely. (see Fig. 5 and 6).
• If your system has more than two wires: Use the cross reference chart to
determine correct wire connections. If you have a four-wire heat/cool system
leave the factory installed jumper between RC and RH attached (see Fig 2.). If
your system has five wires remove the factory installed jumper between RC and
RH (see Fig 3.).
• Electric heat or single stage heat pump systems: These thermostats
are configured from the factory to operate a heat/cool, fossil fuel (gas, oil, etc.)
forced air system. This is correct for any system that DOES NOT require the
thermostat to energize the fan on a call for heat. If your system is an electric heat
or heat-pump system that REQUIRES the thermostat to turn on the fan on a call
4 for heat, remove the yellow factory-installed jumper wire from the Y terminal and
connect it to the A terminal. This will allow the thermostat to energize the fan
immediately on a call for heat. If you are unsure if the heating system requires
the thermostat to control the fan, contact a qualified heating and air condition-
R
ing service person. For single stage heat pump applications (no auxillary heat),
5
install a short jumper wire (not included) across terminals W and Y. If the system
has a reversing valve connection energized in Cooling, attach it to O. If the sys-
tem has a reversing valve connection energized in Heating, attach it to B (see
Mounting Hole
Fig. 4). This thermostat will not provide multi-stage heating or cooling.
D. Mount Thermostat Base: Gently push excess wire back into the wall open-
ing and plug hole with a fire-resistant material, such as fiberglass insulation to
prevent drafts from affecting thermostat operation. Mount the thermostat base
to the subbase using the three captive screws on the thermostat base. (See Fig.
1) Tighten the screws securely. Proceed to Step #5.
Take care when securing and routing wires so they do not short to adjacent
terminals or rear of thermostat. Personal injury and/or property damage
may occur.
