Emerson 1F95-0671 Power Stealing Switch

The Power Stealing Switches (Figure 1, rear view) 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:

  1. The furnace draft inducer motor may run with no call for heat.
  2. The furnace fan may turn on with no call for heat or may not turn off.
  3. The furnace may not turn off when the call for heat ends.
  4. 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.

Emerson 1F95-0671 Programming & Configuration Items

Programming and Configuration Items

  1. "System On" indicates when heating or cooling stage is energized. "System On +2" indicates when addi tional stages are on.
  2. The word "Hold" is displayed when the thermostat is in the HOLD mode. "Temp" is displayed when the thermostat is in a Temporary HOLD mode.
  3. Displays "Change Filter" when the system has run for the programmed filter time period as a reminder to change or clean your filter.
  4. Displays "Set" for setpoint when in Run Program mode.
  5. Displays System Mode (Heat, Em, Auto, Cool, Off) or Time in menu mode.
  6. Displays Fan mode (On, Auto) "Prog FAN On" or "Run Sched" in Menu mode.
  7. Displays "Run Schedule", "Schedule", or "Menu".
  8. Displays "Save" when Cool SavingsTM is working.
  9. Displays "Heat Pump" when system is configured as Heat Pump thermostat.
  10. Displays "Hold" in programmable mode when not in Hold mode. Displays Light Bulb in non-programmable mode.
