n ROOM TEMPERATURE SENSORS
This unit is suitable for either drywall mounting or junction box mounting. The room sensor is provided with screw
terminal blocks for all connections. Remove the cover from the unit and mount the housing base to the wall using the (2)
6/32" x 1" machine screws. Replace the cover and tighten down, using the (2) 1/16" Allen Screws located on the bottom of
the enclosure.
n DUCT AND DUCT AVERAGING SENSORS
Duct temperature sensors - drill a 3/8" hole in the duct and insert the probe through the hole until the foam pad is tight to
the duct. Now insert the (2) screws through the mounting holes in flange and tighten until the unit is held firmly to the
duct.
Duct Averaging sensors - Drill a 3/8" hole in the duct and insert the averaging element through the hole until the foam pad is
tight to the duct. Now insert (2) screws through the holes in the mounting flange and tighten them until the unit is held
firmly to the duct. The sensor should then be strung in a criss-cross pattern throughout the duct (see Figure #2) using the
mounting clips provided, in a pattern that covers the greatest surface area of the duct, to insure that there is no stratification.
When bending the copper tubing, be careful that you use a gradual bend and that you DO Not kink the copper tubing.
n FLUID IMMERSION TEMPERATURE SENSORS
The ACI Fluid Immersion-type sensors are provided with a 2 ½", 4", or 6 ¼" insertion length, 304 series stainless steel
thermowell. The thermowell has a 1/2" NPT external or process thread and a 1/2" NPT internal or instrument thread. Heat
transfer compound may be used but it is not necessary.
n STRAP-ON TEMPERATURE SENSORS
The ACI Strap-On sensors, are provided in a NEMA 1 rated junction box with an adjustable 2" to 5" pipe clamp. The unit
should be mounted on the bottom side of the pipe to ensure proper heat transfer and a true temperature reading. Heat
transfer compound and insulating the sensor will help the overall accuracy of the sensor. By ordering extra straps and
fastening them together, it is possible to make them fit larger pipes.
n OUTSIDE AIR TEMPERATURE SENSORS
The ACI Outdoor Air temperature sensors are provided in a weatherproof enclosure. An optional weatherproof Aluminum
Bell Box or NEMA 4X Polycarbonate enclosure is also available upon request for an additional charge. All of the mounting
hardware is provided with the sensor. Be sure to mount the sensor out of direct sunlight, with the sensor probe pointing
downward.
n STAINLESS PLATE TEMPERATURE SENSORS
The ACI Stainless Plate temperature sensors are mounted on the back of a 1 Gang stainless steel plate. The foam pad will
insulate the sensor from any drafts in the wall. (2) 6/32" x 1" machine screws are provided for junction box mounting.
Be sure that the sensor is not mounted on an outside wall, due to the extreme temperature changes from either drafts or heat
transfer.
