HP/Aux or Dual Fuel – Dual fuel runs either
the heat pump or the aux output, depending
on outdoor temperature. The heat pump with
aux can stage the heat when required to
improve performance.
Dual Fuel: A dual fuel system
combines an energy-efficient
air-source heat pump with a
new or existing oil, gas or
propane furnace. The furnace
runs in place of the heat pump
in cold weather.
Aux (Auxiliary) Heat: When
the a heat pump can no longer
efficiently transfer heat from the
outside air, the thermostat
automatically turns on a
secondary heat source, such as
electric resistive heat.

Anticipators: (1 - 6) Low number = more frequent
cycles, faster response. High number = less frequent
cycles, slower response.
Interstage Differential: 0.5 to 8.0ºF. The proportional
temperature error to trigger the second stage.
HP Balance Point - Minimum outdoor temperature at
which the heat pump runs (requires an outdoor
temperature source).
AUX Balance Point - Maximum outdoor temperature
at which Aux heat system supplements the heat pump
(requires an outdoor temperature source)
