I have a Tempus 7 Timer says 1E:00pm both hot water and heating indicator arrows are stuck on ONCE and CONT Mon 10:EE bottom 1E:00pm both hot water and heating lights are permanently off. All buttons and indicators are frozen. Fuse is ok. I have tried pressing all 4 2nd ON and 2nd OFF buttons simultaneously but it does not reset itself. I have turned the Fused spur off and ON but battery is ok so probably not allowing a complete power down. Anyone have any ideas how to reset it or is it broken past repair?

The usual press time+ and select wasn't working, the battery inside would
prevent a full reset so this procedure does a total system reset.
Mains off
Unscrew with flat screwdriver the holding screw at the bottom of the unit
lift unit off backing plate pulling the bottom towards you
using a thin knife or a screwdriver lift off the back panel to expose the
circuit and the round backup battery
with a small bit of metal ie your screwdriver breifly touch the contact
below the battery to the outer case of the battery ( temporary short )
replace the cover, the unit is now reset to default ( you should be able to
see the display working again if you hold it at a angle )
place back on wall
tighten screw
turn on mains
