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 dis- carded.

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-Rodgers at 9797 Reavis Road, St. Louis, MO, 63123-5398 for proper disposal.

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 appropriate wiring schematic (see figs. 2 through 4).

3.Place base over hole in wall and mark mounting hole locations 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 maintain time and continuously display the temperature during a loss

ENERGY MANAGEMENT RECOVERY

(EMR)

When the EMR feature is activated the thermostat's microcom- puter calculates the time it will take to change the room temperature to the next heat or cool program setting. Then the thermostat will start the system before the next programmed period so that the desired temperature is reached at or near the beginning of the period (the thermostat calculates 15 minutes for every 1°F temperature change). This minimizes the use of auxiliary stages during the transition period to reduce energy costs.

For example: The thermostat is programmed to provide an overnight heating temperature of 66°F, and during the next program period, beginning at 6:00 AM, the programmed tem- perature is 70°F. With EMR activated, the thermostat will auto- matically start the heating system at 5:00 AM, so that the programmed temperature of 70°F is reached by about 6:00 AM.

If the overnight room temperature drops only to 68F°, the thermostat will start the system at 5:30 to reach the programmed temperature of 70°F at 6:00.

The thermostat is shipped with the EMR feature active, which means that the thermostat will start the heating system before the beginning of the next program period. This feature provides better efficiency by allowing gradual temperature changes using only the first stage of heat.

To deactivate the EMR function, see the Configuration menu on Page 5). The thermostat will then wait until the programmed time to start the system for a temperature change.

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 ener- gized in COOL. If the thermostat you are replacing or the heat pump being installed with this thermostat requires a “B” termi- nal, to energize the changeover relay in HEAT, the O/B switch must be moved to the “B” position.
