TEC2102-3 N2 Networked Heat Pump Thermostat
Installation Instructions
Applications
The TEC2102-3 Thermostat is an N2 networked device
that provides control of heat pump equipment. The
technologically advanced TEC2102-3 Thermostat
features a Building Automation System (BAS) N2 Bus
communication capability that enables remote
monitoring and programmability for efficient space
temperature control.
IMPORTANT: The TEC2102-3 Thermostat is
intended to provide an input to equipment under
normal operating conditions. Where failure or
malfunction of the thermostat could lead to personal
injury or property damage to the controlled
equipment or other property, additional precautions
must be designed into the control system.
Incorporate and maintain other devices such as
supervisory or alarm systems or safety or limit
controls intended to warn of, or protect against,
failure or malfunction of the thermostat.
