    I have a 12 year old Narrowboat with a Thermotop C unit, it was installed with the rather basic controller and I wanted something with more timer options. I contacted PB and they were able to recommend this part, installation was easy as it plugged straight into the connector for my old controller. The only thing is the controller skipped the setup where you select the heater model, which threw me for a bit as I got error code T12. This was due to the default heater settings, which weren’t for my model (thus the wbus error). If you get this same issue be sure to google how to change the heater model if it doesn’t match the one in the settings screen. Other than that, I love this new controller, much more up to date!
