Electronic Timer Operation Instructions
This page was
written after I bought the timers and ended up not using them
because the instructions were not enclosed, after finally getting around to
working out how to use them I thought Id put this page up for anyone else in
same position. The timers are actually quite good once you know how to
them. Id be
interested to hear if anyone does actually use this page, if you do
why not drop
me an email to: joe.timerpage AT tozer DOT org DOT uk.
Thanks to Phil Hough for emailing information on Summer Time and CTD mode,
for info on how to reset individual programme timers, Gary Hardman

corrections and Bryan
Elliott for the blank display fix.
