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 suitable container. Refer to www.white-rodgers.com for location to send the 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.Place base over hole in wall and mark mounting hole locations on wall using base as a template (see Fig.1).

3.Move base out of the way. Drill mounting holes.

4.Push wires through opening in thermostat base.

5.Fasten base loosely to wall 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.Connect wires to terminals on base using appropriate wiring schematic (see figs. 2 through 4).

7.Push excess wire into wall and plug hole with a fire-resistant material (such as fiberglass insulation) to prevent drafts from affecting thermostat operation.

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.

FAN (ELE/GAS) SWITCH

For Electric Heat, heat pump or any system that requires the thermostat to turn on the blower on a call for heat– place the FAN (Ele/Gas) switch (Fig. 1) in the ON position. For Auxiliary and Emergency Heat systems that have a fan control to turn on the blower (independent of the thermostat) place switch in the OFF position.

BATTERY LOCATION

“AA” Alkaline Batteries

Two “AA” alkaline batteries are installed in your thermostat with a battery tag to prevent power drainage. Prior to use, open the battery door and remove the battery tag. To open, pull the battery door as shown by the arrow and lift open. The two “AA” batteries will operate all functions or maintain time and continuously display the temperature during a loss of AC power. Installed batteries will also allow programming prior to installation. To replace batteries, pull the battery door shown by the arrow and lift open. Using the polarity indicated inside the battery door, insert the batteries. To close the battery door, swing the door down while pulling in the direction of arrow. Once fully down, snap the door back into position.

Thermostat can be powered by system AC power or Battery. If is displayed, the thermostat is battery powered.Ifis not displayed, thermostat is system powered with optional battery back-up. When battery power remaining is approximately half,

the will be displayed. When “Change ” is displayed, install fresh “AA” alkaline batteries immediately. For best results, use new premium brand alkaline batteries such as Duracell® or Energizer®. We recommend replacing batteries every 2 years. If the home is going to be unoccupied for an

extended period (over 3 months) and is displayed, the batteries should be replaced before leaving. When less than two months of battery life remain, the setpoint temperature will offset by 10 degrees (10 degrees cooler in Heat mode / 10 degrees warmer in Cool mode). If offset occurs, the normal

setpoint can be manually reset with or . Another offset will occur within two days if batteries are not replaced. To replace the batteries, set system to OFF.
