TEC2100 Series Networked Thermostats
The TEC2100 Series of thermostats is a family of
highly advanced thermostats specifically designed for
control of equipment such as rooftop units (with and
without economizers), heat pumps, and single and
multi-stage heating/cooling equipment. The TEC2100
features Metasys® system N2 Bus communication
capability that enables remote monitoring and
programmability for efficient space control. The
TEC2100 used an intuitive, plain text, menu driven
backlit display that makes setup and operation quick
and easy.
The TEC Series includes four models: Single-stage
(TEC2101-1), Heat Pump (TEC2102-1), Multi-stage
(TEC2103-1), and Economizer (TEC2104-1). All
thermostats use a unique proportional control
algorithm that virtually eliminates temperature offset
associated with traditional differential-based
thermostats.
