Looking at some munchkin piping diagrams and was wondering wheather with the vision one controoler when a call for domestics hw is the primary systems pump engernized or not from there diagrams i would gather not the reasons for is should the pump be piped before the boiler pump or after like the zone pumps or does in some way effect the proper operation of the munchkin 1st one waiting for the vision one controller and as for the tt wires in the juction i gather they can be conected to the aux terminals of any cicr relay ex taco sr503 thanks for any input clammy peace

Yes

the boiler pump shuts down on call for DHW. The vision will let you set a time limit for DHW, then go back to space heating. Pipe it like the manual shows, don't forget check valves, it will work just fine. Bryan

Thanks bryan i was just wondering because one of the older munchkin perferred piping arrangement does not show the pump being piped before the boiler pump and shows the boiler pump pumping away and the new diagrams show it pumping into the unit and the dhw pump is piped before it thanks for the help will post upon completion peace clkammy
