Many thanks for another great video, so thoroughly explained! I was worried why my motorised valve was hot at 6:15 when everything was off, and now I know why (but not really happy about it). Still not fathomed out why my boiler shuts down for 10 mins when the valve changes over from HW to heat🤔

amazing! I got stuck today trying to determine which wire did what on a three port valve. Thank you so much for the comprehensive and clear explanation.
