If you have a heat pump HVAC system:
Heat pump with AUX heat (Fast Recovery)
Heat pump with AUX heat (Efficient Recovery)
Heat pump no AUX heat
Note: For two-stage systems your thermostat can recover from a temperature
setback in two ways:
•
Fast Recovery - this uses your 2nd stage to bring the house to target
temperature. This may use slightly more energy.
•
Efficient Recovery - This uses the 2nd stage to bring your house to within a
few degrees of the target temperature and then uses the 1st stage to go the
last bit. (Refer to the Operating Guide for information about setting the
differential). This is more efficient.
