JANUARY 2008 UCCS STANDARDS 15950-35
L. For all applications utilizing outside-air, relief, isolation or exhaust dampers; install an E/P
to automatically close the dampers when its associated air-handling unit or fan is turned off.
The E/P shall be wired (not thru software) so the damper is closed when the fan or AHU is
turned off with the starter switch in the OFF or AUTO position (or in either the Bypass or
VFD modes when a variable-frequency drive is used.) The dampers shall open, or return to
automatic control, as required, when the fan or AHU is turned on, whether the started
switch is in the HAND or AUTO position (or in either the Bypass or VFD modes when a
variable-frequency drive is used.)
M. Layout of Points on Controllers: The points on controllers shall be coordinated for approval
by the UCCS HVAC Shop.
N. Animal-holding areas:
1. Shall be monitored to provide an alarm when University specified (adjustable)
temperaturesare is out of range.
3.06 CONTROL DEVICE LOCATIONS
A. Room thermostats and sensors shall be mounted 5'-0" above finished floor unless otherwise
noted on drawings.
B. Outdoor-temperature-sensing bulbs and sensors shall be located generally on a northern
exposure, in a shaded location, preferably in a place where there is a continuous stream of
outside air over the sensor, unless shown otherwise. Provide sun shield for temperature
sensors. All locations shall be pre-approved by the Owner's Representative.
C. Provide wind-dampening "weatherhead", with insect screen on outdoor-atmospheric-
pressure-sensing point and mount at least 3' above the highest roof structure to minimize
false readings due to wind direction and/or eddies.
D. Remote control devices not in local panels shall be accessible for adjustment and service -
below 6’ above finished floor whenever possible.
E. Locate all control devices wired by the Electrical Contractor under Division 16.
F. Outdoor-relative-humidity-sensing elements shall be located generally on a northern
exposure, in a shaded location, preferably in a place where there is a continuous stream of
outside air over the sensor, unless shown otherwise. Provide a sun shield. If there is an
existing or new dry-bulb temperature sensor, mount the humidity sensor next to the tem-
perature sensor. All locations shall be pre-approved by the Owner's Representative.
G. Freezestats shall be mounted downstream of the first steam or hot water coil of an air-
handling unit. Freezestat locations shall be pre-approved by the Owner's Representative.
H. Use averaging sensors
