The TEC26x6(H)-4 and TEC26x6H-4+PIR Series 
Thermostat Controllers are BACnet® Master-Slave/
Token-Passing (MS/TP) networked devices that 
provide control of two- or four-pipe fan coils, cabinet 
unit heaters, or other equipment using on/off, floating, 
or proportional 0 to 10 VDC control input, three speeds 
of fan control, and dehumidification capability. The 
TEC26x6H-4+PIR Series Thermostat Controllers have 
occupancy sensing capability built into the device. 
These devices maximize up to 30% energy savings in 
high-energy usage light commercial buildings, such as 
schools and hotels, during occupied times by using 
additional standby setpoints. See the Occupancy 
Sensor Operation – TEC26x6H-4+PIR Series 
Thermostat Controllers section for more information.
