I have storage heaters with 2 controls input and boost control. I put the input up to 3 last night and the boost was on 0 and woke up this morning and it was already warm in the room the heat was already coming out? Is this right? I thought i had to put the other control on during the day to release the heat. Its a dimplex storage heater model xt24 series g. Does anybody know how to work these? Thanks
