The TEC2604-4 and TEC2604-4+PIR Thermostat
Controllers are BACnet® Master-Slave/
Token-Passing (MS/TP) networked devices that
provide control of single- or multi-stage unitary rooftop
units with economizers. The TEC2604-4+PIR
Thermostat Controller provides advanced active
occupancy logic that automatically switches occupancy
from Occupied to Unoccupied as required by the
presence of local activity. See the Occupancy Sensor
Operation – TEC2604-4+PIR Thermostat Controller
section for more information.
