Applications
The TEC26x7-2 Series Thermostats are BACnet®
Master-Slave/Token-Passing (MS/TP) networked
devices that provide control of local hydronic reheat
valves, pressure dependent Variable Air Volume (VAV)
equipment with or without local reheat, or other zoning
equipment using an on/off, floating, or proportional
0 to 10 VDC control input. The technologically
advanced TEC26x7-2 Series Thermostats feature a
Building Automation System (BAS) BACnet MS/TP
communication capability that enables remote
monitoring and programmability for efficient space
temperature control.
The TEC26x7-2 Series Thermostats feature an intuitive
user interface with backlit display that makes setup and
operation quick and easy. The thermostats also employ
a unique, Proportional-Integral (PI) time-proportioning
algorithm that virtually eliminates temperature offset
associated with traditional, differential-based
thermostats.
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 TEC26x7-2 Series 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
TEC26x7-2 Series Thermostat.
IMPORTANT:
The TEC26x7-2 Series Thermostats
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.
