I have an H&M water boiler which fires right up when stat calls for heat. Boiler responds to honeywell aqua stat as far as turing on and off when water temp is reached. The pump and boiler continues to run after wall stat reaches set room temp. room stat set at 62 boiler and pump still running at 64'. i lowered aqua stat to 150, boiler does respond to the different temp setting. gages (altitude) 10 to 12lb black needle, 40lb red needle hot.contacts are spotless on aqua stat and on relay which is hooked onto a transformer.
how do i get system to shut down when room stat is reached?
