READ THESE INSTRUCTIONS BEFORE YOU BEGIN INSTALLATION
All ACI thermistors and RTD Room or Space temperature sensors are both non-polarity and non-position sensitive. All
thermistor type room units are supplied with a two-pole terminal block and all RTD's and 592 temperature sensors will be
supplied with either a two or three-pole screw terminal block. ACI Recommends the use of 18 to 20 AWG twisted pair wire or
shielded cable for all sensor installations.
n TROUBLESHOOTING
Sensor reads 0 ohms or very low
Sensor reads infinity or very high
Erratic readings
No Voltage or Current Ouput
No Voltage Signal Output (592-10K)
Sensor or wires are shorted together
Sensor or wires are open
Bad wire connections - Condensation or Moisture problem
Check Power Supply Voltage
Touch sensor and verify that the voltage output increases with
Voltmeter from (-) to (3W) Terminal (Reading in VDC)
Measure Current output changes from (-) to Controllers Input Terminal
(Reading in uA)
No Current Signal Output (592)

n MOUNTING INSTRUCTIONS
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 in the lower right
and left hand corners of the enclosure.
