TEC20x6(H)-2 Series Wireless Thermostat Controllers with Two Outputs,

Dehumidification Capability, and Three Speeds of Fan Control

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. TEC20x6(H)-2 Series Wireless Thermostat 
Controllers control 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 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.

Series Wireless

 

Thermostat Controllers are 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.

This Class (A) digital apparatus meets all the requirements 
of the Canadian Interference-Causing Equipment 
Regulations.

Cet appareil numérique de la Classe (A) respecte toutes 
les exigences du Règlement sur le matériel brouilleur du 
Canada.

RF Transmitters: Industry Canada Statement

The term 

IC

 before the certification/registration number 

only signifies that the Industry Canada technical 
specifications were met.

Le terme « IC » précédant le numéro d'accréditation/
inscription signifie simplement que le produit est conforme 
aux spécifications techniques d'Industry Canada.
