Has any body got the idiots guide to setting the timer on the night heater please. 
just push the buton with the three wavy lines on it, it will come on 
Just leave it on all night as long as you don’t have it on too hot it should keep the cab at a nice steady temp.
I don’t know why they can’t be like they used to be, like an analogue alarm clock with a little red hand which you turned with a winder which determined when it came on.
At a push, I could understand that you might want to set it to come on on a Monday morning before you leave for the weekend, but who ever needs to set a night heater to come on at a certain time in three weeks’ time?
