TEC2101-3 N2 Networked Single-Stage Thermostat Installation Instructions

1

Applications

The TEC2101-3 Thermostat is an N2 networked device 
that provides control of single-stage heating/cooling 
equipment. The technologically advanced TEC2101-3 
Thermostat features a Building Automation System 
(BAS) N2 Bus communication capability that enables 
remote monitoring and programmability for efficient 
space temperature control. 

North American Emissions Compliance

United States

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 is required to correct the 
interference at his/her own expense.

Canada

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.

Installation

Location Considerations

Locate the TEC2101-3 Thermostat:

on a partitioning wall, approximately 5 ft (1.5 m) 
above the floor in a location of average 
temperature

away from direct sunlight, radiant heat, outside 
walls, behind doors, air discharge grills, stairwells, 
or outside doors

away from steam or water pipes, warm air stacks, 
unconditioned areas (not heated or cooled), or 
sources of electrical interference

Note:

Allow for vertical air circulation to the 

TEC2101-3 Thermostat.

IMPORTANT:

The TEC2101-3 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.
