REMEMBER, this thermostat includes an automatic compressor protection
feature to avoid potential damage to the heat pump system from short cycling (See
Compressor Protection).
6.4
Efficient Recovery Mode (ERM™)
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 Efficient Recovery Mode (ERM
™
) 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.
6.5
Compressor Protection
This thermostat includes an automatic compressor protection feature to avoid potential
damage to the heat / cool system from short cycling. This thermostat automatically provides
a 5-minute delay after turning off the heating or cooling output to protect the compressor.
NOTE: The installer can reset the thermostat and bypass the compressor protection
features by pressing the RESET button. This will erase all entered programs, current
time of day, day of week and other user settings and should only be used during
installation for testing purposes or to reset a thermostat to regain normal operation.
This will return all Thermostat settings to their default values. The user will have to
re-program all of the erased settings.
6.6
High Temperature Safety Switch
While the thermostat is in the HEAT mode of operation (selector switch in the HEAT position),
the thermostat will mechanically turn-off if the room temperature raises higher than 99˚F
(37˚ C). There is also a software feature that will automatically turn-off the thermostat in
HEAT mode if the temperature raises higher than 93˚ F (34˚ C).
WARNING!
Press RESET button using a paper clip or a small pencil tip. This will reset the
thermostat and return all settings to their default values. Verify your thermosta t is
controlling your system, see Testing Your New Thermostat. If the problems still persist,
call a professional service technician immediately to verify proper system operation.
