DESCRIPTION
The technologically advanced KTEC Zoning Control
System provides efficient space temperature control for
constant volume zoning systems in multi-zone heating and
cooling applications. This cost-effective zoning control system
can operate as a stand-alone system, or it can be mapped
into a supervisory controller via a BACnet - Master-Slave/
Token-Passing (MS/TP) Bus to enable remote monitoring and
programmability within a Building Automation System (BAS).
FEATURES
• Fully scalable zoning control system meets the
requirements of small and large zoning control
systems
• BACnet MS/TP communication provides compatibility
with a proven communication network
• True stand-alone zoning control system offers
additional application flexibility
• Backlit Display offers real-time control status of
the environment in easy-to-read, English plain text
messages with constant backlight that brightens
during user interaction
• Simplified setpoint adjustment enables the user to
change the setpoint by simply pressing the UP/DOWN
arrow keys
• Configurable binary inputs provide additional inputs
for advanced functions such as remote night setback,
service or filter alarms, motion detector, and window
status
• Over 20 configurable parameters enable the zoning
control system to adapt to applications with varying
requirements, allowing installer parameter access
without opening the controller cover
