• 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.
