Single Proportional Output and One-Speed Fan Control

Installation Instructions

TEC2145-4
Applications
The TEC2145-4 Thermostat Controller is an
N2 networked device that provides control of two-pipe
fan coils, cabinet unit heaters, or other equipment
using a proportional 0 to 10 VDC control input and
one-speed fan control.
The technologically advanced TEC2145-4 Thermostat
Controller features a Building Automation System
(BAS) N2 Bus communication capability that enables
remote monitoring and programming for efficient space
temperature control.
The TEC2145-4 Thermostat Controller features an
intuitive User Interface (UI) with backlit display that
makes setup and operation quick and easy. The
thermostat controller also employs a unique,
proportional control algorithm that virtually eliminates
temperature offset associated with traditional,
differential-based thermostat controllers.
IMPORTANT: The TEC2145-4 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.

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 will be 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 TEC2145-4 Thermostat Controller:
on a partitioning wall, approximately 1.5 m (5 ft)
above the floor in a location of average
temperature
away from direct sunlight, radiant heat, outside
walls, outside doors, air discharge grills, or
stairwells; or from behind 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
TEC2145-4 Thermostat Controller.
