my potterton netaheat timer (30 years old) comes on during the night when I?
I have a Potterton Neta heat which is 30 years old. i set the timer to come on at 6.30-8 am but during the night the boiler fires up! I wonder if it is the timer at fault and can a digital timer replace the old fashioned clock style timer?
