RTAC Communication Loss Fan Control - AdaptiView Upgrade

Issue:

Communication Loss with Fan Control after upgrading an RTAC unit with low ambient capability

Resolution:

• Communication Loss due to incorrect setting for air flow steps...see snapshot below
• Airflow Variable Speed Fan for Circuit 1 and Circuit 2 needs to be "0"
• Air Flow Step 4 for Circuit 1 and Circuit 2 needs to have a value
• The default values are likely not correct for your unit. These values must be derived from the original CH530 configuration. See example below
• This should resolve the Communication Loss diagnostic
• Note: This does not apply to units with the CH530 control
