The local series fan within the terminal unit operates whenever the unit is in
the occupied mode. The volume of air delivered to the VAV zone is constant,
but the temperature of the delivered air varies. As the zone requires less
cooling, the primary air damper closes. As the primary air damper closes,
the air mixture supplied to the zone contains less cool air and more warm
plenum air. Remote heat or terminal reheat can provide additional local
heating.
Auxiliary Temperature Sensor
The auxiliary temperature sensor allows the operator to monitor air tem-
perature leaving a reheat device or measure duct temperature for automatic
operation of a standalone UCM.
Zone Temperature Sensors
Five zone temperature sensor configurations are available:
• sensor only
• sensor with adjustable setpoint and communications jack
• sensor with night setback override button, cancel button, and communica-
tions jack
• sensor with adjustable setpoint, night setback override button, cancel
button, and communications jack
• sensor with digital display, adjustable setpoint, night setpoint override
button, cancel button, and communications jack
CO
2
Sensor
A CO
2
sensor may be connected to the UCM damper control to sense CO
2
levels in the space. This signal is communicated to the CCP for demand
ventilation calculation and control.
Occupancy Sensor
A normally open occupancy sensor contact may be connected to the UCM
damper control binary input to indicate zone occupancy.
Operator Display
A ¼ VGA monochrome LCD touch screen display is installed on the CCP. This
display provides setup, diagnostic, and seven-day scheduling functions to
the system.
