TEC2604-4 and TEC2604-4+PIR BACnet® MS/TP Networked

Multi-Stage Economizer Thermostat Controllers Installation Instructions

Applications

The TEC2604-4 and TEC2604-4+PIR Thermostat

Controllers are BACnet® Master-Slave/

Token-Passing (MS/TP) networked devices that

provide control of single- or multi-stage unitary rooftop

units with economizers. The TEC2604-4+PIR

Thermostat Controller provides advanced active

occupancy logic that automatically switches occupancy

from Occupied to Unoccupied as required by the

presence of local activity. See the Occupancy Sensor

Operation – TEC2604-4+PIR Thermostat Controller

section for more information.

The technologically advanced TEC2604-4 and

TEC2604-4+PIR Thermostat Controllers feature a

Building Automation System (BAS) BACnet MS/TP

communication capability that enables remote

monitoring and programming for efficient space

temperature control.

The TEC2604-4 and TEC2604-4+PIR Thermostat

Controllers feature an intuitive user interface with

backlit display that makes setup and operation quick

and easy. The thermostat controllers also employ a

unique, Proportional-Integral (PI) time-proportioning

algorithm that virtually eliminates temperature offset

associated with traditional, differential-based

thermostat controllers. Economizer functions include a

0 to 10 VDC control signal, dry bulb changeover

strategy, adjustable minimum position, and mixed air

setpoint control.

Installation

Location Considerations

Locate the TEC2604-4 or TEC2604-4+PIR Thermostat

Controller:

• 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, outside doors, air discharge grills, or

stairwells, and from behind doors

• away from steam or water pipes, warm air stacks,

unconditioned areas (not heated or cooled), or

sources of electrical interference

For integrated Passive Infrared (PIR) models, be sure

that the thermostat controller is located centrally, where

occupant movement is frequent.

IMPORTANT: The TEC2604-4 and

TEC2604-4+PIR Thermostat Controllers are

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.

toutes les exigences du Règlement sur le matériel

brouilleur du Canada.
