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.
