PIR APPLICATION GUIDE FOR TB7200 AND TB7300 SERIES THERMOSTATS
63-4526—01 4
• Unoccupied Timer Disable: In certain application cases, it may be desired to never let the local area enter the unoccupied
mode and always stay at the stand-by occupancy level when no activity is present.
This allows for advanced flexibility when used in conjunction with a network or in cases when areas always need to be on
stand-by status ready to respond to demand at any point in time.
Fig. 1. Unoccupied timer set 6 Hours and stand-by timer set to 2 hours
When the local PIR occupancy routine is running at the thermostat, the zone will drift into unoccupied mode when the unoccu-
pied timer is set above
its factory default value of 0.0 hours
Fig. 2. Unoccupied timer set 0 Hours and stand-by timer set to 2 hours
When the local PIR occupancy routine is running at the thermostat, the zone will never drift into unoccupied mode when the
unoccupied timer is set to its factory default value of 0.0 hours
• Network Priority and Local Occupancy Routine: The internal PIR occupancy logic implementation in conjunction with
network commands has been conceived to give the most flexibility while allowing for simple implementation and use.
