This procedure is applicable only to the CBX32MV-XX-230-6-06 and higher
and all CBX40UHV models. This procedure is for configuring the heat strips so
that they will be detected by the thermostat:
• Power must be applied to the air handler but NOT to the Smart Hub.
• Disconnect any communication wiring between the Smart Hub and indoor
unit prior to electric heat discovery.
• The air handler control must be in idle mode (decimal blinks at 1 Hertz—0.5
second ON, 0.5 second OFF to use the following procedure.
1. Select field test mode—press and hold the push button until solid "–"
appears; release button. Display will blink.

2. Push and hold button and wait for the display LED to show "H" (capital H),
then release the button.
3. The air handler control cycles the indoor blower motor "on" to the selected
heat speed and stages the electric heat relays "on" and "off" to automatically
detect the number of electric heat sections. The air handler control stores
the number of electric heat sections, then automatically exits "Field Test
Mode".
4. The thermostat will now detect the heat strip information stored in the air
handler control.
5. Turn off power and connect all low voltage wiring (power and communication
to and from the Smart Hub).
6. After completing the commissioning of the system then check to see if you
have electric heat or emergency heat.
