We have a narrow boat with a model 701 controller that is broke. Will your model 801 be compatible. We only want it for a timer and thermostat

Hi Carol, the Eberspacher 801 controller has been replaced by the 802 series version, very similar visually though. The 802 series, similar the 801 series does NOT have timer functionality as you wish for unfortunately. Please advise your exact heater model, perhaps send a photo of your Eberspacher heater data plate to sales@butlertechnik.com - this will allow us to recommend your best option of controller from Eberspacher's current range
