WIRING INSTRUCTIONS
ACI recommends 16 to 26 AWG twisted pair
wires or shielded cable for all sensors.
Signal wiring must be run separate from
low and high voltage wires (24/120/230
VAC). All ACI thermistors are non-position
sensitive. All thermistor type room units are
supplied with a two-pole terminal block.
The number of wires needed depends on
the application. All wiring must comply
with all local and National Electric Codes.
Note:
When using a shielded cable, be sure
to connect only (1) end of the shield to
ground at the controller. Connecting both
ends of the shield to ground may cause a ground loop. When removing the shield from the sensor end,
make sure to properly trim the shield to prevent any chance of shorting.
Wiring Instructions for optional ACI/LCD
The optional ACI/LCD must be powered with either a 24 VAC or 9-35 VDC power source. The ACI/LCD uses
a half-wave bridge rectifier to convert the AC voltage to a useable DC voltage. Two separate cables must
be pulled for the ACI/LCD to work properly. One 2 conductor 18 to 22 AWG shielded cable for the supply
voltage and a second 18 to 22 AWG 2 to 4 conductor shield cable for the Temperature sensor, Set Point and
Override Outputs to the controller. ACI recommends18 to
22 AWG twisted pair wires or shielded cable for all sensor
installations.
