OUTSIDE AIR SERIES
TEMPERATURE TRANSMITTER
Installation & Operation Instructions
GENERAL INFORMATION
The ACI Outside Air Series sensors and transmitters
are single point sensors that output 4-20 mA with an
optional voltage signal output of 1-5VDC or
2-10VDC signal to BAS or controller. All ACI/TT and
TTM temperature transmitters can be powered from
either an unregulated or regulated 8.5 to 32 VDC
power supply.
MOUNTING INSTRUCTIONS
For optimal temperature measurement, follow
these tips:
• Avoid mounting to chimney walls, above
windows, above vents, near doors, or dampers.
• Mount at least 1'-2' (0.3-0.6 m) below eave to prevent
thermal radiation from affecting performance –
see FIGURE 2 (p. 2).
• Mount at least 4' (1.22 m) above ground to prevent
thermal
radiation
performance.
• Mount in shade on North side of the structure to
minimize sun exposure.
hemisphere the South side of the building is
where the sensor should be mounted.
• The plastic tube that houses the sensor must be
pointed down to avoid debris, water, or ice
potentially a ecting sensor performance.
Attach the base directly to the wall. Mounting holes
are located at the corners of the housing – see
FIGURE 1 (right). Drill pilot holes for the mounting
screws. Use the enclosure mounting holes as a
guide, or use the dimensions listed below to
measure out. Install the PG11 watertight fitting
supplied with the sensor if not using conduit. The
outer knockout ring (PG 11/16) on housing
should not be removed when using a ½" NPT
conduit fitting.
Take care when mounting. Sensors should not be
placed in direct sunlight, or any other potential heating
or cooling sources that could a ect temperature being
sensed.
