For helping the customer
Over the past few years, we have received numerous emails from customers seeking help to get their failed heat pumps working again. A common issue we've encountered is with the controller of the SDDC dc inverter heat pump, which has been prone to failure.
Unfortunately, the controller for the SDDC heat pump is no longer being produced. If your SDDC heat pump was manufactured earlier than 2018, we may not be able to provide much support. In such cases, we recommend considering the purchase of a new heat pump.
However, we are pleased to announce that we are still producing new SDBW heat pumps. If you need new SDBW heat pump, or need assistance, please don't hesitate to reach out to us for help.
