ADD-ON
Any furnace can only have one additional appliance added to the ductwork. Other
items which do not drastically reduce the air flow are allowed.
2.6 MAX/EVO
AC/AUXILIARY SENSOR INSTALLATION
Mandatory for
MAX
series furnaces when equipped with an A/C coil. Optional for
EVO
series
furnaces when equipped with an A/C coil, defaults to full speed on A/C if not installed.
AC/Auxiliary sensor kit contents:
AC/ Auxiliary sensor mounted in sensor box with 86” of sensor cable.
Three (3) mounting screws.
Four (4) cable clamps and clamp screws
Mounting the AC/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 AC/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 approximately 10” above the cabinet and centrally on the
side of the plenum.
Also make sure that the cable from the AC/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 AC/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.
