ISARs dont have a flow switch unless the pre heat disablement kit has been fitted. The thermistor is ridiculously sensitive to temp change in the plate, hence the problem with 'C' and 'D' cycling with a drip on a tap etc.
Chances are the OPs rads are heating with the hot tap on DV passing.
OP, run a hot tap and feel the far left pipe on the boiler..... if it gets hot thats your problem...
