Hi Tom, I programed all 4 zones to OFF for all 7 days of the week. The clock and day of week are set ( day 2 being Monday). Reset dial to Auto and all 4 rads are switched on and the slider set at 10. Theoretically all rads should be off and cold…when in fact they are all on! The override shows 1 bar and not 4 bars. Any light you could throw on this would be most appreciated. Thanks
