As you have found having a S/Y Plan plus Boiler Relay system will not work.
It was never designed/intended/published to work in this way.
Regarding cycle rates on an S/Y Plan plus HR92 zoned system an explanation is being prepared.
When I have something that can be easily explained and understood in laymans terms I will share it.
Very interesting, thanks - I look forward to your further info.

Did this ever happen Top Brake? I think it probably relates to the short-cycling thread elsewhere.
