■ The Energy Efficient Recovery (EER™) feature looks ahead up to 2 hours prior to the end of
the set-back (or set-up) period to begin monitoring system performance and calculating
when to turn on the system. It also determines whether the auxiliary 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 EER™
feature will lock out the auxiliary stages until 30 minutes prior to the upcoming setpoint time
to utilize the most energy efficient heat pump (first) stage. The auxiliary stages of heating and
cooling will be available during this lock-out period to maintain the setpoint temperature
should the heat pump not be able to keep up with the heating or cooling demand.
■ To control the system, press the SYSTEM switch until HEAT, COOL, EMER, or AUTO appears
in the display. The thermostat will not properly control the system to your desired setpoint
temperature unless it is in one of these operating modes.
■ The EMER (emergency) mode of heat can be manually selected to bypass heat pump oper-
ation and switch to auxiliary or emergency stages of heating to control setpoint temperature.
■ To enter AUTO, you must first be in PROGRAM mode. Press PROG/MAN button until
PROGRAM appears in display. Then press SYSTEM button to enter AUTO.
■ The QuickSet™ feature programs each individual day simultaneously with the identical
program. Each and every day can then be individually modified to suit specific
needs/desires.
