I have an Evohome with S-plan controlled by 2 BDR91's, I'd like to disable the 'low demand' feature (cycling the boiler 1 min in 10), as this runs even when the heating and hot water is set to 'off'. I have a wood pellet biomass boiler which takes at least 10 mins to start, so asking it to run for 1 min isn't very helpful.
