TEC2003-3 Multi-Stage Wireless Thermostat Controller Installation Instructions

1

Applications

The TEC Series Wireless Thermostat Controller 
System provides wireless networked control of 
Heating, Ventilating, and Air Conditioning (HVAC) 
equipment on a Building Automation System (BAS) 
that enables remote monitoring and programming. This 
TEC Series System integrates into a supervisory 
controller using BACnet® Internet Protocol (IP) or 
BACnet Master-Slave/Token-Passing (MS/TP) 
communications.

TEC20 Coordinators allow the supervisory controller to 
communicate with multiple TEC Wireless Thermostat 
Controllers.TEC200x-3 Series Wireless Thermostat 
Controllers provide networked control of a variety of 
staged equipment. TEC2003-3 Multi-Stage Wireless 
Thermostat Controllers control multi-stage packaged 
heating/cooling equipment.

The wireless mesh network uses ZigBee

 technology 

to enable remote monitoring and programming and to 
enhance reliability by providing redundant transmission 
paths through other TEC Wireless Thermostat 
Controllers, creating a resilient, self-healing mesh 
network.

IMPORTANT:

The TEC2003-3 Wireless 

Thermostat Controller is intended to provide an input 
to equipment under normal operating conditions. 
Where failure or malfunction of the thermostat 
controller 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 controller. 

This equipment has been tested and found to 
comply with the limits for a Class A digital device 
pursuant to Part 15 of the FCC Rules. These limits 
are designed to provide reasonable protection 
against harmful interference when this equipment is 
operated in a commercial environment. This 
equipment generates, uses, and can radiate radio 
frequency energy and, if not installed and used in 
accordance with the instruction manual, may cause 
harmful interference to radio communications. 
Operation of this equipment in a residential area is 
likely to cause harmful interference, in which case 
the user will be required to correct the interference 
at his/her own expense.

RF Transmitters: Compliance Statement 
(Part 15.19)

This device complies with Part 15 of the FCC Rules. 
Operation is subject to the following two conditions:

1.

This device may not cause harmful interference, 
and

2.

This device must accept any interference 
received, including interference that may cause 
undesired operation.

Warning (Part 15.21)

Changes or modifications not expressly approved by 
the party responsible for compliance could void the 
user’s authority to operate the equipment.
