Is there a simple way to control two pumps where I can give priority to one pump? What I am trying to do is when my in slab pump kicks on it really sucks the BTU`s. If my pump for the shop kicks on the water is not hot enough to kick on the fan on the water to air heat exchanger ( even thou it`s piped into my input loop before the in floor pump ) . So both pumps run until the floor is satisfied. I would like to prioritize one pump.
Thanks
