Heat System Type: Heatpump 1 or 2 Stages
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.
NOTE: You can set the HP or Aux Balance Point
from 0º to 90º, or select OFF to disable heat pump,
Aux lockouts.

Cold Weather Compensation: Modifies the
humidifier output to prevent condensation on the
windows. Requires an outdoor temperature
source (CHV-THSAT, or CHV-TSTAT with CHV-
RTHS, CHV-RTS, or CHV-RSS).

Heat Pump, 1 or 2 Stages, Aux Heat or Dual Fuel

Press and hold the MODE and VIEW buttons simultaneously for five seconds to
enter the setup mode.
Dual Fuel: A dual fuel system
combines an energy-efficient
air-source heat pump with a
HPump
new or existing oil, gas or
2
propane furnace. The furnace
HP/Aux
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.

Intrstg Differential:
HP Balance Pt:
AUX Balance Pt:
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)
