I have an older 2006 coach. It uses the 5 button dometic controller to control 3 15K heat pumps and the aquahot furnace.
If I want to use the newer 10 button controller, I must purchase 3 new heat pumps and upgrade the furnace controller.
The new 10 button controller is incompatible with older dometic interface controllers.
Here is a link to the new furnace controller.

Newmar discussion areas on other forums discuss this issue. I tried to post a picture of my controller, mounted under a sink, but could not.
You are confusing some things. YES, the 5 button controller board will ONLY work with a 5 Button wall tstat. You CANNOT mix any part of the 5 button system with a 10 button system. You only have to upgrade to a 10 button if you purchase NEW Penguin's. The Penguin's come with onboard 10 button control boards. They make a 10 button to 5 button adapter kit board replacement for the new Penguin's. To make the NEW Penguin work with a 5 button tstat. Newmar used a separate Dometic Board in a galvanized Box to utilize operation of the AC/Heat system to come on when NOT in the RV. Like to engage the Genset when you were away and you wanted to have the Roof AC come on when the temp in the RV was too hot. THAT is what that board under the sink is used for. IF you have a separate ON/OFF switch system JUST for your Webasto/Aqua Hot, that must be turned ON to utilize Hydronic heating controlled by the Dometic wall tstat system. Do you have a separate switch system just to turn on the Aqua Hot in your unit? Remember, the OP states he try's to start the Webasto but it fails to ignite. This would NOT be caused by the Dometic system. Remember he states he HAD the Webasto switch ON and the motor ran but did not ignite. Doug
