Emerson White Rodgers 1F86-0244 Thermostat Manual
This thermostat is intended for use with a low voltage NEC Class II system. Do not use this thermostat with a line voltage system. If in doubt about whether your wiring is millivolt, line, or low voltage, have it inspected by a qualified heating and air conditioning contractor or electrician. Do not exceed the specification ratings. All wiring must conform to local and national electrical codes
This control is a precision instrument, and should be handled carefully. Rough handling or distorting components could cause the control to malfunction.

White Rodgers 1F86-0244 INSTALLATION
REMOVE OLD THERMOSTAT
- Shut off electricity at the main fuse box until installation is complete. Ensure that electrical power is disconnected.
- 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.
- Identify each wire attached to the old thermostat using the labels enclosed with the new thermostat.
- Disconnect the wires from old thermostat one at a time. DO NOT LET WIRES FALL BACK INTO THE WALL.
- Install new thermostat using the following procedures.
ATTACH THERMOSTAT BASE TO WALL
- 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.
- Place base over hole in wall and mark mounting hole locations on wall using base as a template (see Fig.1).
- Move base out of the way. Drill mounting holes.
- Push wires through opening in thermostat base.
- 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.
- Connect wires to terminals on base using appropriate wiring schematic (see figs. 2 through 4).
- 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.
