Installing Remote Indoor Temperature/Humidity Sensor(s)
One remote indoor temperature/humidity sensor and 35' of 18 gauge 5-conductor shielded cable is included with the
controller. This sensor must be installed for proper operation. Mount the temperature/humidity sensor in a location
least likely to be affected by open doors, rack-mounted fans, radiant heat sources, etc. Locating the sensor between
both return grilles is often the best location, but every installation is unique. Location height should be approximately
60" above the floor. The sensor should be installed on a 2" x 4" junction box to allow for control wire conduit (see
Figure 21). Use shielded cable to connect to controller.
1. Connect wires from the 18 gauge shielded cable to terminals #12, #13, #18, #19 and #22.

2. Connect the other end of the shielded cable to the sensor
terminals. Be sure wires are connected to proper terminals
as shown in table above. Sensor jumpers need to be
positioned for 0-1 V. With sensor oriented as shown in
image to right, move both jumpers to left position (DP1 and
DP2 set to OFF).
This applies to all temperature/humidity sensors connected
to the LC controller.
Sensor is best mounted on a junction box, and it is
recommended that the cable be in conduit.
