One follow up question: you indicate that voltage boosting can be removed (Settings -> Advanced, and set the ‘Boost Time’ to 0) if driving a relay. On the other hand, if I understand correctly, it is probably required to drive a valve. As far as I can tell, the setting is global (applies to all stations). If I am going to drive both valves on some stations and relays on others, I expect I should keep the Boost Time to a non-zero value, under the expectation that it is required to successfully drive valves, and it will not impact relays overly negatively?
