Evohome - Boiler firing with no demand
Why is it that even after the demand for heat has fallen to zero, minutes later my boiler is asked to fire? At best this is wasting money, and in the worst case scenario there is a danger of the boiler locking out due to overheat. (Purple line demand, green boiler being asked for heat, red is just an indicator of water temperature, and due to the way it is collected, has a small delay)
This particular plot is taken at a time where I turned off (via override) the last active zone. Not sure if that has any bearing on not.
