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 DI is used.
When the system is in OFF mode, the contact will
remain in its unoccupied status independently of the
occupied / unoccupied schedule.

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.
