I only came across this very recently, it has several circ pump functions, one of which is, if selected, will control the dT by changing the pump speed. It defaults to 20C but is selectable, a very nice feature.
Has anyone got one of these and are using this feature?
Also do these boilers like the older ones maintain the ignition settings for up to 60 secs before allowing modulation, causing frequent cycling due to the flow temperature exceeding the target temperature by 5C if the heating demand is very low like UFH, all/most gas boilers fire up at ~ 65% of rated output but allow modulation almost instantly after firing up.
