Mount the thermostat horizontally on the wall:
1. Pull the wires through the wire hole on the wallplate.
2. Position the wallplate on the wall with the arrow pointing
up. Level the wallplate for appearance only.
3. Use a pencil to mark the mounting holes.
4. Remove the wallplate from the wall and drill two 3/16 in.
holes in the wall (if drywall) as marked. For firmer
material such as plaster, drill two 7/32 in. holes. Tap the
wall anchors (provided) into the drilled holes until flush
with the wall.
5. Pull the wires through the wire hole on the wallplate and
position the wallplate over the wall anchors.
6. Insert the mounting screws into the wall anchors and
tighten.

NOTES:
1. When used in a single-transformer system, leave
metal jumper wire in place between Rc and R. If
used on a two-transformer system, remove metal
jumper wire between Rc and R.
2. Common wire is optional when thermostat is used
with batteries. When using separate transformers
for heating and cooling, the common must come
from the cooling transformer.
3. If thermostat is configured for a heat pump in the
Installer Setup, configure changeover valve for
cool (O-factory setting) or heat (B).
4. Reference economizer literature for wiring details.
When set for economizer operation, the A terminal
provides the occupancy signal. (Power indicates
occupied.)
5. Sensor wires must have a cable separate from the
thermostat control cable.
63-2635—2 6
Terminal “A” Wiring Details for Economizers
— Wire the A terminal to the W7212 “N” terminal, or the
W7459 “TR” terminal.
— When using dual transformers at the thermostat, the cooling
transformer must power the economizer.
— The A signal is powered from the R terminal and energizes
the economizer to signal occupied status and drive the
damper to the set minimum position.
