Emerson White Rodgers 1F97-1277 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 backup. |
*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.
