1) Contact Grasslin UK for warranty coverage:
http://www.grasslin-controls.co.uk/contact.html

2) Reset timer and reprogram.
Move slide switch to to right 'set own program'
Then when times are programmed, move slide switch fully right to 'run own program'

3) Test that unit is receiving at least 80% rated voltage 240V x 80% = 192V

4) Buy another unit

Looking for instructions for boss therm digital centralheating programmer

Grasslin qe1 and qe2 manual does not show troubleshoot section.
http://www.grasslin-controls.co.uk/assets/graphics/static/QE1-QE2_GB%20instructions.pdf

1) Remove power to unit and see if it will reset.
2) Press reset and hold button longer
3) Manual says: SLIDE SWITCH MUST ALWAYS BE LEFT IN "RUN PRESET PROGRAMME" OR, "RUN OWN PROGRAMME" POSITION, OTHERWISE THE CLOCK WILL NOT RUN, AND NO SWITCHING WILL OCCUR.
4) Timer has stopped working. I test timers, and they all stop working one day.

That's a good old timer.

There are several programmable timers on the market.
Intermatic EJ500 is simple to install and program. Works on battery but is for incandescent light only, not for fans.

GE 15071 from Home Deport is inexpensive replacement and works with fans, lights.
Needs no battery. Uses electric circuit to operate clock.
