REMOTE PROBE HUMIDITY/
TEMPERATURE TRANSMITTER
SERIES
Installation & Operation Instructions

GENERAL INFORMATION

The A/TT Remote Probe 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.
The sensor is designed for use with electronic
controllers in commercial heating and
cooling building management systems. All
A/TT temperature transmitters can be
powered from either an unregulated or
regulated 8.5-32 VDC power supply.
The A/RH Remote Probe Series sensor is a
relative humidity transmitter that can be
powered with either an AC or DC supply
voltage. The RH Remote Probe transmitter is
eld selectable with a 4-20 mA, 0-5 VDC, or
0-10 VDC output signal that is equivalent to 0
to 100% RH. All RH units are shipped from the
factory set to 4-20 mA output.
For optimal readings, follow these tips:
• Do not install on external walls.
• Avoid air registers, di users, vents, and windows.
• Eliminate and seal all wall and conduit penetrations. Air migration from wall cavities may alter temperature readings.
• Do not install near heat sources. eg: lamps, radiators, direct sunlight, copiers, chimney walls, walls concealing
hot-water pipes.

MOUNTING INSTRUCTIONS

Remote Probe sensors may be mounted using a 3/4" mounting clip on walls or with cable ties. The sensor
should be mounted in an area where air circulation is well mixed and not blocked by obstructions.
The RH Remote Probe includes a Black Rubber Cap that ts over the sensor lter. This cap should be placed
on the sensor lter during wet/wash down processes. The cap must be removed for normal operation.

TRANSMITTER MOUNTING

Attach the base directly to the wall by rst drilling pilot holes for the mounting screws. Alternatively, you
may refer to the dimensions listed in FIGURE 1 (top) to measure out.

SENSOR MOUNTING

To x the probe on a wall, ACI recommends a height of 48-60" (1.2-1.5 m) o the ground and at least 1.5' (0.5
m) from the adjacent wall. Slide the sensor probe through the mounting clip - see FIGURE 2 (p. 2). Drill a
screw through the socket and tighten to the wall. Refer to Wiring Instructions (p. 2-4) to make necessary
connections.
