I would wonder if the circuit is not dedicated.

My Experience have taught me that anyone who does not follow UNICO s installation procedures and who does not have the manufacturer (UNICO) do the Commisioning is lost at sea without a paddle

consider yourself lucky that you got 6 years with no Maintenance.

Thank You.
