Applications
The TEC2664Z-3 Rooftop Controller is a
BACnet® Master-Slave/Token-Passing (MS/TP)
device that operates with a Johnson Controls®
TEC2647Z-3 or TEC2647Z-3+PIR (occupancy sensor
model) Zone Controller to provide efficient space
temperature control in constant volume zoning
systems. This technologically advanced rooftop
controller provides a proportional 0 to 10 VDC control
output to the bypass damper of a rooftop unit based on
the sensed pressure in the duct, and controls up to
two stages of heating and two stages of cooling.
The TEC2664Z-3, TEC2647Z-3+PIR, and
TEC2647Z-3 Controller combination can operate as a
stand-alone zoning system or it can operate with a
Building Automation System (BAS) that enables
remote monitoring and programming in networked
zoning systems.
The TEC2664Z-3 Rooftop Controller features an
intuitive user interface with backlit display that makes
setup and operation quick and easy. The rooftop
controller also employs a unique,
Proportional-Integral (PI) time-proportioning algorithm
that virtually eliminates temperature offset associated
with traditional, differential-based rooftop controllers.

IMPORTANT:
The TEC2664Z-3 Rooftop Controller
is intended to provide an input to equipment under
normal operating conditions. Where failure or
malfunction of the rooftop 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 rooftop controller.
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.
