All Heat Pump Lockout Mode
AZ6500 Series ONLY.
The Heat Pump Lockout is controlled through
the Auxiliary Set mode. When this Auxiliary
Set button is on, the control will run in electric
resistance heat (Stage 3) mode only, with the
heat pump operation (Stage 1 and 2 heating) off.
When the Auxiliary Set button mode is off, the
heat pump is allowed.
The heat pump lockout mode is utilized in the
Class 2 mode.
NOTE
: If the Heat Pump Lockout mode and
Boost Heat mode are both selected as active in
the auxiliary settings, the Heat Pump Lockout
mode takes priority, and Heat Pump modes
remain off.
Boost Heat Mode
AZ6500 Series ONLY.
When the Boost Heat Auxiliary Set button is
enabled and the outdoor temperature is above
25°F, the first stage heat (heat pump only) is
locked out.
It will be controlled through an Auxiliary Set
Button mode. Staged Heating selection logic and
Resistance Heat Lockout mode have priority over
this function.
This Boost Heat setting is used to provide
supplementary heat to the heat pump operation
in conditions where the heat pump only operation
(Stage 1 heat) is not sufficient to maintain a
consistent comfortable room temperature for the
consumer.
Fan Only Mode
: All models
In the Fan Only mode, the indoor fan runs
continuously at the fan speed selected (High or
Low). All other loads are de-energized.
