Auxiliary sensor kit contents:
Auxiliary sensor mounted in sensor box with 86” of sensor cable.
Three (3) mounting screws.
Four (4) cable clamps and clamp screws.
Mounting the auxiliary sensor
a) Disconnect the POWER from the furnace.
b) Find a location in the plenum down-stream of the air conditioning coil or auxiliary heating
unit to mount the auxiliary temperature sensor. This location should be centrally located in
the air stream of the plenum and far enough from the A/C coil or heat source, so that the
auxiliary sensor senses an even temperature from the coil. On a wood furnace the
sensor should be located as high up the supply plenum as possible. The minimum height
of 10” above the cabinet and centrally on the side of the plenum. Also make sure that
the cable from the auxiliary sensor will reach back to the wiring channel on the
furnace and that the cable can be routed to avoid contact with any extremely hot
surfaces (i.e. flue pipe).
c) In the plenum location chosen, drill a 7/8” hole or construct a hole large enough to insert
the auxiliary sensor into the plenum. The sensor probe should not touch the plenum metal
when the box is mounted to the plenum.
d) Remove the cover from the sensor box. Using the three screws provided mount the
sensor box to the plenum through the three pilot holes in the sensor box. IMPORTANT:
Ensure that the SENSOR ORIENTATION is correct with the AIRFLOW arrow. See sensor
mount in sensor box.
e) Place the cover back on the sensor box.
f) Remove the cover from the wiring channel on the furnace.
g) Locate the 5/8” hole with the black plug on the wiring channel and remove the plug. (Plug
can be discarded).
h) Fit the end of the sensor cable through the 5/8” hole and make the cable connection to
the auxiliary sensor female plug on the circuit board (note plug release tab orientation).
i) Press the strain relief bushing on the auxiliary sensor cable in to the 5/8” hole.
j) Replace the wiring channel cover.
k) Reconnect the power to the system and test the system. When the power is reconnected
this RESETS the circuit board to recognize that the sensor is connected.
