Hi - after a power cut the clock on the display of C27 timer has not come on so there is no power going to it. I cannot find a separate fuse going into it - does the Honeywell C27 have the fuse inside it. I am helping a lady on her own over the phone so relying on her to feedback to me. Can you help?

Press the SET and CH buttons at the same time. The 2 outside buttons. This will restore the factory presets. Then she should be able to program the timer.

If the battery has been removed and re-installed the timer will bre running on "Reserve" and there will not be a CLOCK display. The only way to reset this is to remove the battery for an extended period of time and then install it or a new battery.
