Homebase Electronic Timer Operation Instructions


Homebase electronic twenty 20 program timer



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 I’d put this page up for anyone else in the
same position. The timers are actually quite good once you know how to program

them. I’d 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,

Mike England for info on how to reset individual programme timers, Gary Hardman

for CTD mode corrections and Bryan Elliott for the blank display fix.

To clear timers

To clear a single timer and reset it to" --:-- "press the 'finger' button.



Once programmed the timer can be set using the triangular button with the picture of a finger,
there are three basic modes

  1. OFF: always off
  2. ON: always on
  3. AUTO switches off and on based on the set timers.
    When AUTO OFF is shown the timer socket is currently off, when AUTO ON is
    shown the timer socket is currently on.

    (On the LCD display 'Auto' with 'on' or 'off' means that the timer will switch on and off
    according to the settings you've made; when it shows 'auto on' it just means that the
    timer output is currently switched on, and when it shows 'auto off' the timer output is
    currently switched off.


Random Delay Start Mode (RND)

Random Delay Start mode delays the programmed start and finish times by between 2 and 32 minutes,

this can be used to give the impression that a timer is not being used to turn lights on and off.

  1. Press the RND button to enable or disable random mode.
  2. If random mode is set "RND" appears on the right hand side of the display, blank in normal mode.

set CTD mode:

  1. In normal mode, press '<-' to enter CTD mode
  2. Press 'SET' and the '<-' and '->' keys to preset the countdown time (in the same way
    as for the timer modes above)
