No just put it on a timer FCU and set the timer for the periods you want it to turn on and off. Obviously the periods you wish to time will be set when your heating is turned off via the time clock/programmer.
Yea but as I said before, if someone decides to turn the central heating on manually (which we do all the time) and this overrides the timer, the element is still going to be on for no reason if its within the time its set to be on.
