Eberspacher EasyStart controller installation.
I finely installed the Eberspacher EasyStart Timer in lieu of the ancient Espar DigiMax. The controller allows me to turn the water heater Hydronic D5 and the furnace Airtronics D2. I can read faults from both units, set time for D5 and many other options.
I must say that the English translation of the Eberspacher manual assume you donít need one because you already know, so calling it a manual is an oxymoron. Big thanks to one fellow on the Sprinter Forum for help by pointing me to 12.1 line of the controller service code to allow addition of the second (D5) heater.
