Installation, Remove OLD Thermostat | White Rodgers 1F81-71 specification

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.

PRE-INSTALLATION SET-UP

1.Remove the packing material from the thermostat.

2.This thermostat is configured from the factory to operate a heat/cool, fossil fuel (gas, oil, etc.), forced air system with up to 2 stages of heat and 2 stages of cool. It is configured correctly for any system that DOES NOT require the thermo- stat to energize the fan on a call for heat.

If your system is an electric heat or heat-pump system that REQUIRES the thermostat to turn on the fan on a call for heat, locate the GAS/ELECTRIC switch on the back of the thermostat (see fig. 1) and switch it to the ELECTRIC position. This will allow the thermostat to energize the fan immediately on a call for heat. If you are unsure if the heating/ cooling system requires the thermostat to control the fan, contact a qualified heating and air conditioning service person.

3.Two jumpers are also located on the back of the thermostat, so that you may customize the thermostat to meet your individual preference (see fig. 1). In most applications, the factory jumper settings provide the most comfortable and convenient thermostat operation.

Jumper wire W905 determines how fast the system cycles on and off, based on temperature change. As shipped from

the factory, the thermostat will maintain a very consistent room temperature, usually within 1°F of the thermostat setting. To achieve a slower on and off cycle, providing a slightly wider temperature span, cut and separate jumper wire W905.

Jumper wire W903 controls the Energy Management Recov- ery (EMR) feature. EMR allows the thermostat to energize the heating system up to 30 minutes before the time pro- grammed into the thermostat. The thermostat will then energize the system to gradually raise the temperature to your programmed temperature by using the most efficient stage of heat practical.

For example, assume that the thermostat is programmed overnight to 66°F and the room temperature is 66°. If the next program is 7 AM, 70°F (an increase of 4°), the thermostat will

start the system 30 minutes before 7 AM. If the temperature is in the room is within 2°F of your next programmed temperature, the thermostat will not start the system early.

DO NOT clip jumper wire W903 unless you wish to perma- nently disable the EMR feature.

INSTALLING THE THERMOSTAT

1.Gently remove the cover by pulling it straight off the base. Forcing or prying on the unit may cause damage to the unit.

2.Remove the battery tab. With the batteries installed, the Armchair Programming feature allows you to program the thermostat before installing it on the wall.

3.Pull wires through the hole in the thermostat base and place the base over the hole in the wall. Mark mounting hole locations on the wall using the base as a template.

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

5.Fasten the base loosely to the wall, as shown in fig. 2, using two mounting screws. Place a level against the bottom of the base, adjust until level, and then tighten the screws. (Level- ing 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 the base snugly, use plastic screw anchors to secure the base.

6.Check that the system is turned off. Connect the wires beneath the terminal screws on the base using the appropri- ate wiring diagram (see figs. 3 through 5).

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.
