In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
I recently had a radiant zone added to my existing baseboard system. The manifold came with a i-Link SP-81. The existing aquastat/controller is a Honeywell 8148a with Taco Zone Sentry valves. . The tech plans to wire the tt from the i-link to the tt on the 8148a . Is this proper as the tt from the zone valves is already connected?
