INSTALLATION
REMOVE OLD THERMOSTAT
1. Shut off electricity at the main fuse box until installation is
complete. Ensure that electrical power is disconnected.
2. Remove the front cover of the old thermostat. With wires
still attached,
remove wall plate from the wall. If the old
thermostat has a wall mounting plate, remove the thermostat
and the wall mounting plate as an assembly.
3. Identify each wire attached to the old thermostat using
the labels enclosed with the new thermostat.
4. Disconnect the wires from old thermostat one at a time.
DO NOT LET WIRES FALL BACK INTO THE WALL.
5. Install new thermostat using the following procedures.
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 nonabsorbent 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 suit-
able container. Refer to www.white-rodgers.com for location to
send product containing mercury.
ATTACH THERMOSTAT BASE TO WALL
1. Remove the packing material from the thermostat. Gently pull the
cover straight off the base. Forcing or prying on the thermostat
will cause damage to the unit.
2. Connect wires beneath terminal screws on base using ap -
propriate wiring schematic (see figs. 2 through 4).
3. Place base over hole in wall and mark mounting hole loca -
tions on wall using base as a template.
4. Move base out of the way. Drill mounting holes.
5. Fasten base loosely to wall, as shown in fig. 1, using two
mounting screws. Place a level against bottom of base,
adjust until level, and then tighten screws. (Leveling is for
appearance only and will not affect thermostat operation.)
If you are using existing mounting holes, or if holes drilled
are too large and do not allow you to tighten base snugly,
use plastic screw anchors to secure subbase.
6. Push excess wire into wall and plug hole with a fire-resistant
material (such as fiberglass insulation) to prevent drafts from
affecting thermostat operation.
ELECTRIC/GAS JUMPER (Fan Option)
Read the following information before clipping the nonelectric
heat jumper. If you are unsure of your application, contact a
qualified service person.
If your emergency or auxiliary system will energize the blower, then
jumper, W904, on the thermostat base must be cut (see fig. 1).
If your emergency or auxiliary heat system requires that the
thermostat energize the fan circuit, do not cut jumper W904.
OPTIONAL BATTERIES
With two "AA" batteries installed, your thermostat will continu -
ously display the temperature during a loss of AC power.
O/B TERMINAL SWITCH SELECTION
The O/B switch on this thermostat is factory set to the “O”
position. This will accommodate the majority of heat pump ap-
plications, which require the changeover relay to be energized
in COOL. If the thermostat you are replacing or the heat pump
being installed with this thermostat requires a “B” terminal, to
energize the changeover relay in HEAT, the O/B switch must be
moved to the “B” position.
