Has anyone tried useing a Taco pump relay (with priority) to look after indirect, or is the Viessman control the only option.



Thanks, Dobber

    Which Boiler

    Are we talking Vitodens 100? If so, simple...Using a Taco Zone Control EXP version add theTaco PC600 post purge card. Gives you a seperate XX to take back to DHW on the Vitodens 100 to get the boiler into high fire. You wire the zone control no different than if using a conventional boiler. Make sure you leave the priority switch in the on position. The zone control will pick up the card once it is plugged in and run priority within itself. The Vitodens will shut down RT and go into high fire once DWH receives the signal.
