in THE MAIN WALL

Like the title states getting an f07 error code= exhaust temp too high. Domestic hot water works fine but won't make any hot water for the heating baseboards. 2 zones neither work, taco controller lights on calling for heat, natural gas unit. Please help getting some warm weather the next couple of days and want to get this fixed before the cold comes back. Thanks

    You may have air in the radiator system. Do you know how to purge air from your radiators?

    After you make that expensive repair and you still have the same problem, What will you check next?

    I do know how to purge the radiators, my only concern is the error code, would air in the radiators result in an error code regarding the exhaust temp? I haven't been able to get home yet and investigate, just looking for potential areas to look into

    Thank you for the response ahead of time it is greatly appreciate.
