Thanks sam. original was honewell so client got BG to replace but they changed to drayton. i thought (clutching straws ) this may have altered something so i fitted new honeywell. sort of cancelled out any incorrect wiring prob by fitting stopcock after 3port on CH flow and shut it to prevent any flow either way.
