Hello again guys,
I was gifted a Grundfos circulation pump from a boiler hot water system recently. I am trying to adapt this pump for my fermentation cooling system. I am planning on using a BCS 460 to monitor temperatures as well as manage the workload of telling when to circulate the cold water via water pump. The Grundfos pump really only has 2 wires amounting to a positive and negative feed (basically an unwired plug). I'm guessing that the pump was told manually when to kick on via the boiler system by directly either feeding it power or lack there of. Are there any plumbing/HVAC guys out there that could shed any light on either manipulating a grundfos pump or the capabilities of using a BCS 460 to control pumps?
Any feedback is better than none, I appreciate any help!
