The display indicates how many hours have been
requested in the bottom left hand corner. Hot Water
can be temporarily switched on in the same way, using
the +HR button on the right of the display.
Power interruption
In the event of a mains supply failure, the back-up battery ensures the programmer
continues to keep time and retain your stored programme. The screen will go blank, but will
return when power is restored.
Resetting the programmer
Press the reset button with a non-metallic pointed tool to restore the built in programme plus
the time and date. The display will then show the current state of the configuration switches.

versa.
