I have a Taco SR504 that controls my secondary pumps in my primary secondary manifold.
I want to wire the primary pump so it is on demand with call for heat and starts when there is a call for heat from one of the zones.
Instructions say to put in a jumper between ZC and ZR and shows the end switch to a boiler.
I can use the End switch for pump right?
Is there a designation for which terminal is Hot or Neutral?
I thought I would wire end switch to an outlet so I can just unplug pump if I need to service it.
