In March 2025, customers were informed that the integrated network interface that was purchased with the heating solution would be deactivated and would cease to function, citing that the warranty period had elapsed on the affected products. Affected customers should buy a different interface for remote control called a &amp;quot;Vitoconnect&amp;quot;, which does not offer equivalent functionality.

The manufacturer usually does not repair logic boards, but only replaces them when they fail (even if it is just a 5 ct component) at costs of several hundred to a thousand Euros per board, making many repairs unnecessarily cost prohibitive, leading people to replace entire heating installations even when it wouldn&amp;#039;t be necessary.&lt;br /&gt;
