  2. Remove the front cover of the old thermostat. With wires still attached, remove the 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 the 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 that 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 that 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. Refer to www.thermostat-recycle.org for a location to send products 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 the base using the appropriate wiring schematic (see figs. 2 through 4).
  3. Place base over the hole in wall and mark mounting hole locations on wall using base as a template.
  4. Move the base out of the way. Drill mounting holes.
  5. Fasten the base loosely to wall, as shown in fig. 1, using two mounting screws. Place a level against the bottom of the 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 the holes drilled are too large and do not allow you to tighten base snugly, use plastic screw anchors to secure sub base.
  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)

EMERSON-White-Rodgers-1F89-211-Non-programmable-Electronic-Digital-Heat-Pump-Thermostat-fig.1
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 the 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 continuously 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 applications, 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.
