Installing White Rodgers 1F95-1277

Pull the thermostat body off the thermostat base. Forcing or prying on the thermostat will cause damage to the unit.
Place base over hole in wall and mark mounting hole locations on wall using base as a template.
Move base out of the way. Drill mounting holes. If you are using existing mounting holes and the holes drilled are too large and do not allow you to tighten base snugly, use plastic screw anchors to secure the base.
Fasten base snugly to wall using mounting holes shown in Figure 1 and two mounting screws. Leveling is for appearance only and will not affect thermostat operation.
Connect wires to terminal block on base using appropriate wiring schematic.
Push excess wire into wall and plug hole with a fire resistant material (such as fiberglass insulation) to prevent drafts from affecting thermostat operation.
Carefully line the thermostat up with the base and snap into place.

White Rodgers 1F95-1277 Battery Location

2 "AA" alkaline batteries are included in the thermostat at the factory with a battery tag to prevent power drainage. Remove the battery tag to engage the batteries.
To replace batteries, set system to OFF, remove thermostat from wall and install the batteries in the rear along the top of the thermostat (see Figure 1). For best results, use a premium brand "AA" alkaline battery such as Duracell® or Energizer®. If the home is going to be unoccupied for an extended period (over 3 months) and is Battery indicator low displayed, the batteries should be replaced before leaving.

White Rodgers 1F95-1277 Power Stealing Switches

The Power Stealing Switches (Fig. 1) should be left in the "On" position for most systems. The information in the following table details the thermostat power method and switch options.

Thermostat Power Method	Switch Position/Description
Battery Powered, no 24 Volt system power available.	Switches "On", thermostat runs on batteries.
Hardwired with Battery Back-up, for 24 Volt systems with common connection from transformer to "C" terminal on thermostat.	Switches "On", thermostat runs on power directly from transformer with battery back- up.
*Battery Powered with Power Stealing Assist, for 24 Volt systems with no common connection from transformer to "C" terminal on thermostat.	Switches "On", thermostat runs on batteries and supplemental power drawn through the heat or cool circuit.

*Power Stealing Assist is very reliable to increase battery life, but on a small number of heating or cooling systems with high impedance electronic modules you may observe one of the following conditions:

The furnace draft inducer motor may run with no call for heat.
The furnace fan may turn on with no call for heat or may not turn off.
The furnace may not turn off when the call for heat ends.
The air conditioner may not turn off when the call for cool ends.

If the Power Stealing Assist method is not compatible with your system, place the Power Stealing Switches to "Off". This cancels Power Stealing Assist, operates the thermostat on batteries and corrects the condition.

(No Heat Pump) with Single Transformer

Single Stage and Multi-Stage Connections

Refer to equipment manufacturers’ instructions for specific system wiring information. This thermostat is designed to operate a single-transformer or two-transformer system. You can configure the thermostat for use with the following fossil fuel systems:

SINGLE STAGE (SS 1) gas, oil or electric.
MULTI-STAGE (MS 2) gas, oil or electric.
After wiring, see INSTALLER CONFIGURATION section for proper thermostat configuration.

Figure 3 – Heat Pump Systems

Heat Pump Connections

If you do not have a heat pump system, refer to figures 3 & 4. Refer to equipment manufacturers’ instructions for specific system wiring information. You can configure the thermostat for use with the following heat pump systems.

HEAT PUMP TYPE 1 (HP 1). Single stage compressor system; gas or electric backup.
HEAT PUMP TYPE 2 (HP 2). Multi-stage compressor or two compressor system with gas or electric backup.
After wiring, see INSTALLER CONFIGURATION section for proper thermostat configuration.
