I recently added a second floor addition. For the radiant floor system my plumber installed a Rinnai C85 tank less heater with 3 circulatory pumps. The entire floor is considered one zone even though there are several loop circuits to heat the floor evenly.
My question is how to hook up the TACO SO 503 controller (that he told me to purchase) to a thermostat that triggers all three pumps to come on at the same time? So far I have only been able to get it to turn one at a time. My plumber is a considerable distance away (for him) and has been less than forthcoming with info or when he's likely to show. I'm trying to get this done so I can move upstairs to so I can finish the downstairs.
I appreciate any advice and I will check back this evening. Thank you.
