Prog rec Progressive recovery enabled
Default value = Off
Progressive recovery is automatically
disabled if DI 1 and / or DI 2 are
configured remote NSB
Off, = no progressive recovery
The programmed occupied schedule time is the time at which
the system will restart.
On, = progressive recovery active.
The programmed occupied schedule time is the time at which
the desired occupied temperature will be attained. The
thermostat will automatically optimize the equipment start
time.
In any case, the latest a system will restart is 10 minutes prior
to the occupied period time.
Heat Pump models only
high bp High balance point
Default value = 90 °F ( 32.0 °C )
Function will only be enabled if OS
(outside air temperature sensor) is
connected.
In Heating or Auto mode, it is the outside air temperature
value at which the auxiliary heat will be cut off. Above that
value, only the heat pump will be used to maintain the heating
setpoint
34 to 90 °F ( 1.0 to 32.0 °C )
low bp Low balance point
Default value = -12 °F ( -24 °C )
Function will only be enabled if OS
(outside air temperature sensor) is
connected.
In Heating, Cooling or Auto mode, it is the outside air
temperature value at which the heat pump operation will be
cut off. Below that value, only the auxiliary heat will be used
to maintain the heating setpoint
-40 to 30 °F ( -40 to -1.0 °C )
Comf/eco
Comfort or economy mode
Default value = Comfort
Sets the operation and interaction mode of the heat pump
with the auxiliary heat.
Comfort mode. In Heating mode.
If the heat pump is not able to satisfy the heating setpoint, the
auxiliary heat will be energized to satisfy the same heating
setpoint.
Economy mode. In Heating mode.
If the heat pump is not able to satisfy the heating setpoint, the
auxiliary heat will be energized to satisfy only when the
temperature has dropped 2.0 °F ( 1.1 °C ) below the heating
setpoint. Selecting economy mode will add a deadband
between the heatpump & auxiliary heat in heating mode. The
actual temperature maintained will be lower than the true
heating setpoint to maximize the heat pump operation.
When the outdoor air temperature drops below the low
balance point, the deadband will be eliminated and the
auxiliary heat will maintain the true heating setpoint alone.
Economy mode. In Emergency mode.
If Emergency heat mode is selected, the setpoint maintained,
will be the heating setpoint.
re valve Reversing valve operation O/B
Default value = O
Heat pump reversing valve operation
O will energize the valve in cooling operation.
B will energize the valve in heating operation
O or B
