I have Munchkin 140M R2 with a 925 Control Board. The way it was originally piped it appears to have Primary circulator Taco 0010-F3 without IFC on the return side. Currently, the indirect hot water tank is coming off the Secondary piping and using a Taco 007-F5. There are also 5 additional zones using Taco 00R-F6-1IFC pumps.
What I would like to do is repipe the indirect Super Stor hot water tank and potentially use the Vision 1 system with outdoor reset. According to the manuals it says to use Taco 0011 with IFC on the boiler supply side for the Super Stor, While the primary circulator pump should be a Taco 0010 with IFC piped on the return side.
Does anyone know if it would be possible to use the existing Taco 007-F5 without the IFC and pipe it directly off of the supply side of the boiler. Or is this pump too small or won't work because it is missing the IFC? It would be a short run of pipe. Most like a tee off the supply, then circulator, then a short run to a ninety into the Super Stor and then similar piping back out to the Return side on the boiler. Also, will the fact the Taco 0010 primary circulator pump on the boiler return not having an IFC cause problems? Just trying to use what I already have available.
Also, If I don't use the Vision 1 will this piping still work if the hot water tank calls for heating? So basically, repipe as I mentioned above and then have both the Primary 0010 circulator running on the return side of the boiler at the same time as the Taco 007 running on the supply side pushing into the hot water tank?
Thanks in advance for any insight anyone can provide!
