6. Replacement AHC Configuration – 24 volt mode
Replacement AHC boards need programmed and will
not run without configuration IN 24 Volt Mode. There are
2 ways to perform the configuration. 1 of the methods
is required to get the unit running. Combining 2 or more
methods will result in unwanted operation.
1. The most complete configuration will be accomplished
using the Diagnostics Mobile App. In this app, there
are configurations for the model number, blower delays
and accessories.
2. There is a Button Press method to configure the size
of the air handler and is accomplished by pressing
the S1 button on the bottom of the control board in a
sequence explained in this document.
Only 1 of these methods should be used.
After conguration, power cycle the air
handler.

7. Button Press AHC Configuration Method: Method #2
Replacement AHC will need to be configured for unit size. Airflow will be set at 400 cfm/ton based on unit size configura-
tion. These configurations can be done through the Diagnostics Mobile App with no manual steps or can be done manu-
ally without the Diagnostics Mobile App.

not been pressed for 2 seconds, Red LED will an-
nounce successful programming.
After conguration, power cycle the air
handler.
Red LED will turn on for 5 seconds announcing the
configuration has been stored in NV memory cor-
rectly. Red LED will be on for only 2 seconds if not
stored properly. Programming is complete.
8. Replacement AHC Configuration – LINK Communicating Mode:
The System Controller (SC360) will load important parameters in communicating mode and no interaction is necessary
when replacing the AHC. IF the AHC and the System Controller (SC360) need replaced at the same time - contact your
local FSR or technical support agent.
