The TEC21x6(H)-4 and TEC21x6H-4+PIR
Series Thermostat Controllers are N2
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 TEC21x6H-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.
