Temporary Program Override
The Model 5200 is equipped with an auxiliary heat option switch which is set at
installation for either an electric or fossil fuel (gas, oil or propane) auxiliary heat source.
For heat pump units with an electric auxiliary stage, both the first and second stages of
heating will run when a call for second stage heat is made. For heat pump units with a
fossil fuel auxiliary stage, the first stage will be locked out one minute after a second
stage heat call, and the second stage alone will be used.
1. Press and hold the or button. The current setpoint temperature will be displayed
in the place of the current room temperature, and the indicator SET TEMP will be displayed.

when the or button is released. Continuing to
hold the or button for 3 seconds or longer will
allow the user to temporarily override the current

Adaptive Recovery Mode (ARM™)
This thermostat is equipped with a special feature to maximize your energy savings by
utilizing the most effective source of heating or cooling to meet your program needs during
recovery from setback (or setup) temperatures. Our Adaptive Recovery Mode (ARM™) feature
is designed to automatically calculate when to turn your first (heat pump) stage of your
multi-stage heating or cooling system to meet your upcoming comfort setpoint temperature
setting. While in normal operating mode, this feature will start calculating the start time for
your first stage (heat pump) two hours prior to the upcoming comfort setpoint temperature.
During this two hour time period it will monitor performance and control your system staging
requirements. The second (auxiliary) stages of heating or cooling will be available during this
2-hour period if required to meet extraordinary heating or cooling requirements.

The Recirculating Fan Mode provides more even temperature distribution and improves
indoor air quality by circulating air through the furnace filtration system more often. The
Recirculating Fan Mode can be selected by moving the fan switch to the recirculate position
( ). If no call for heating or cooling occurs within the fan off cycle set in section 4.3.5,
the fan will run for 12 minutes. The highest setting, 120 minutes (factory default), will run
the fan least often – 9% minimum run time. The lowest setting, 40 minutes, will run the fan
