The TEC22x4-3 thermostats are LONWORKS® networked devices providing control of single- or multi-stage unitary rooftop units with economizers. The TEC2204-3 is non-programmable; the TEC2264-3 adds programmability (schedules, clock). Both provide remote monitoring via BAS LONWORKS network communication for efficient space temperature control.
