Applications

The TEC2104-3 Thermostat is an N2 networked device 
that provides control of single- or multi-stage unitary 
rooftop units with economizers. The technologically 
advanced TEC2104-3 Thermostat features a Building 
Automation System (BAS) N2 Bus communication 
capability that enables remote monitoring and 
programmability for efficient space temperature 
control.

Installation

Location Considerations

Locate the TEC2104-3 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 

TEC2104-3 Thermostat.

IMPORTANT:

The TEC2104-3 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. 

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.

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.
