Hello Everyone,
First some information, I hope it's clear;
I have a Burnham ES2 Gas Boiler with a Taco SR502 switch, there are two Taco 007-F5 pumps connected to the boiler. One pump is connected to a thermostat that controls a single loop around the first floor with radiators. The other pump is connected to the Taco SR 502 switch but not too a thermostat, in fact the loop that connects to the second pump was never completed. It goes around the basement but where the pipes meet the corners the elbow are missing on the pipes. The last homeowner probable wanted to put radiators on the 2nd floor, he died before it was completed. When I opened the ballvalve I heard water pouring into the basement and shut it off. I opened the Taco SR 502 switch and the 2nd pump is wired up with power and ready to go.
Now to my question. I bought a Caleffi 172 Manifold Mixing Station with High Efficiency pump. Rather than adding radiators to the 2nd floor I want to add hydronic radiant heat to two rooms on the first floor.
1.HOW DO I WIRE UP THE MIXING STATION PUMP ( I KNOW HOW TO WIRE UP THE POWER)?
2. WHICH PUMP GETS THE THERMOSTAT WIRES?
I not sure how to set this up so the call for heat goes to the correct pump.
Any help would be really appreciated.
Thanks,
Brian
