White Rodgers 1F72 Mounting and Wiring
Electric/Gas Jumper (Fan Option)
If your emergency or auxiliary system will energize the blow- er, then jumper W906 on the thermostat base must be cut (see fig. 1). If your emergency or auxiliary heat system requires that the ther- mostat energize the fan circuit, do not cut jumper W906. If you are unsure of your application, contact a qualified service person.
°F or °C Selection
The factory default setting for temperature display is Fahrenheit. If you want the temperature in Celsius, clip jumper W904.
Fast or Slow Cycle Selection
The factory default setting is fast cycle, which cycles 1st stage at approximately 1.2°F and 2nd stage 0.75°F. If you prefer slow cycle, clip jump W905. The 1st stage and 2nd stage would be 1.5°F and 1.2°F respectively.
Energy Management Recovery (EMR)
This thermostat is set to operate with EMR. This causes the thermostat to start the heating or cooling system early to have the room temperature reach the program setpoint at the time the period is to start. To disable EMR, clip jumper W903 (see Fig. 1).
O/B Terminal Switch Selection
The O/B switch on this thermostat is factory set to “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.
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.
- Connect wires beneath terminal screws on base using ap- propriate wiring schematic (see figs. 2 through 4).
- 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.
- 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 appear- ance 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.
- Push excess wire into wall and plug hole with a fire-resistant material (such as fiberglass insulation) to prevent drafts from affecting thermostat operation.
Battery Location
This thermostat does not require batteries to operate. The 2 “AAA” alkaline batteries are for the thermostat to remember the programming if AC voltage is lost. If the display shows BATT or when AC power is not present, the batteries are low and should be replaced with fresh “AAA” alkaline batteries. For best results, replace all batteries with new premium brand alkaline batteries such as Duracell® or Energizer®. To replace the batteries, install the batteries along the top of the base (see fig.
1). The batteries must be installed with the positive (+) ends to the right.
