stages
H lock
Outside air temperature heating
lockout
Default value = 120 °F ( 49 °C )
Disables heating stage operation based on outdoor air
temperature.
Function will only be enabled if OS ( outside air temperature
sensor ) is connected.
From -15 °F up to 120 °F ( -26 °C up to 49 °C )
C lock
Outside air temperature mechanical
cooling lockout.
Default value = -40 °F ( -40 °C )
Disables cooling stage operation based on outdoor air
temperature.
On economizer model, free cooling will not be disabled by this
function.
Function will only be enabled if OS ( outside air temperature
sensor ) is connected.
From -40 °F up to 95 °F ( -40 °C up to 35 °C )
Unocc TM
Unoccupied Timer value
Default 0.5 hours
Time delay between the moment where the thermostat toggles
from occupied to unoccupied after the last movement has
been detected by the
PIR motion detector.
Range is: 0.5 to 24.0 hours in 0.5 hour increments
2/4event
Number of events configuration
Default value = 2 event
2 events, will set up programming for the following
Event 1 is for Occupied setpoints
Event 2 is for Unoccupied setpoints
4 events, will set up programming for the following
Event 1 is for Occupied setpoints
Event 2 is for Unoccupied setpoints
Event 3 is for Occupied setpoints
Event 4 is for Unoccupied setpoints
aux cont
Auxiliary contact configuration
Default value = N.O. normally open
This contact can be used to energize peripheral devices such
as: lighting equipment, exhaust fans, economizers, etc.
This contact will operate in parallel with the internal
occupied/unoccupied schedule of the thermostat or the
remote NSB contact if DI1 or DI2 is used.
When the system is in OFF mode, the contact will remain in
its unoccupied status independently of the occupied /
unoccupied schedule.

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
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
