Install the Thermistor Probe
1. Route the length of field-supplied copper wire needed
to connect the thermistor probe from the evaporator
coil to the input lead. (This wire may be 18–14 AWG
shielded or unshielded up to 400 ft (121.92 m) long)
Note:
The field-supplied wires may run along with the
power wires through existing or new conduit.
2. Connect the input lead to the
I
CUBE™ module as
shown in FIG. 6. The input lead may be inserted into
any of the four connectors on the
I
CUBE™ module.
Note:
Make sure the input pins are properly aligned with
the input lead connector.

3. Route the input lead above the tab and around the
I
CUBE™ module as shown in FIG. 7.
4. Cut the input lead to the appropriate length:
–
For enclosure installations, cut the input lead length
to ensure the connection is inside the enclosure as
shown in FIG. 7.
–
For bracket installations, cut the input lead to an
appropriate length inside the condensing unit control
panel.
5. Use the provided wire connectors to connect the input
lead to the routed 18–14 AWG shielded or unshielded
field-supplied wire.
