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.

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)

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.
