In older pre-beta versions of the firmware a heat demand of less than 10% would trigger the heating relay (for sub minute lengths of time) but not the boiler relay at all. Has this changed in the current beta versions ?
I don't think anything has changed in low load operation sub 10% (1 min in 10min, 6 cph) the cycle rate is sacraficed to maintain a min on time
