Unoccupied Timer Disable
It might be preferable for the local area to stay out of
Unoccupied mode and always stay at the Stand-By
occupancy level when no activity is present. In
instances when areas always need to be in Stand-By
mode, ready to respond to demand at any given point
in time, we recommend disabling the Unoccupied timer.
When the local PIR occupancy routine is running at the
thermostat controller, the zone drifts into Unoccupied
mode when the Unoccupied timer is set above its
factory default value of 0.0 hours.
For more information on occupancy sensor operation,
refer to the TEC2x45-4, TEC2xx6(H)-4,
TEC2xx6H-4+PIR, and TEC2xx7-4 Series Thermostat
Controllers Application Note (LIT-12011594).
