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

  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. Connect  wires  beneath  terminal  screws  on  base  using  ap- propriate wiring schematic (see figs. 2 through 4).
  3. Place base over hole in wall and mark mounting hole locations on wall using base as a template.
  4. Move base out of the way. Drill mounting holes.
  5. 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.
  6. 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.
