Energy Efficient Recovery
The energy efficient recovery feature looks ahead up to 2 hours prior to the
end of the setback (or set-up) period to begin monitoring performance and
calculating when to turn on your system. It also determines whether the aux-
iliary heat or cool stages should be activated prior to setpoint time to meet
your chosen setpoint temperature. The thermostat will indicate “EER” in the
display when this program feature is active. The energy efficient recovery
feature will lockout the auxiliary stages until 20 minutes prior to upcoming
setpoint time to utilize the most energy efficient first stage. The auxiliary
stages of heating and cooling will be available during this lock-out period
to maintain the setpoint temperature should the system not be able to
keep up with the heating or cooling demand.
