[QUOTE="jl-heating, post: 61868, member: 1917"] The reasoning for three cores to the tank stat (heat call and heat satisfied). call to open valve, satisfied to close valve. The reasoning for the heating off output needed at the programmer programmer goes off on timed and shuts the valve on grey. Where does the valve default to when everything is off. default is closed on heating . How does it stall at the mid position, god knows how but when both hot water/heating are calling valve is central. What the exact functions of putting supplies to various colours at the valve blue, neutral. g/yellow, earth white, 28 mm only. grey, satisfied/hot water only orange. power to boiler/pump when heat calling and stats calling heating and hot water.
