MajorTech MTD8 Digital Geyser Timer

Our new office at 43 1st Avenue in Newton Park was using almost 3 times the amount of electricity as the previous office.

It took us a while to found the cause as all the equipment was still the same. 

Turns out we have a much bigger geser and left unattended it uses around 24 units of electricity a day.  

We looked around at some of the heavy duty timers as the standard pool timer at 10amp is not enough for a geyser and would melt.


We found the Majortech MTD8 Digital timer with 8 on/off programmable settings that can run up to 20A.   We did not find the manual that was supposed to be in the box.A quick email later and a very prompt response from majortech and we have the PDF version of the manual.

I am sharing it here in case I lose it or anyone else is looking for it as the manual is not posted on their website.

We have set the geyser to be on from 4am to 6am and off the rest of the day and so far we still have hot water.

    thanks for the info.. on the paperwork that comes with the timer they’ve omitted the most important instruction… the one that refers to switching on and off before setting to auto otherwise timer wont work once again thanx

    the figures around the centre figures are to small for a 1936 eye. The instruction leaf is also in very fine print. Could you send one for me via e.mail. product = mtd 8

    Thank you

    Is there a programable bypass or must I make use of another line for a bypass. That is in case when you need to switch a light on during off periods? Perhaps you could add a manual bypass switch to the timer

    Would it be harmfull to the timeswitch if it get backfeed on the live output from a bypass switch.

    I would not suggest a bypass as I do not think there is enough protection against backfeed. A bypass is not necessary as you can manually turn the switch on and off using the front panel buttons on the timer. Check the power rating on whatever you are connecting to make sure it does not exceed 16A.

    Download the PDF from the bottom of the post. The writing and the pictures are bigger. My timer never came with an installation leaflet and I battled to find the manual. That is why I shared it when I was sent it.

    Hi David

    You are a star. You gave me the full picture. The instructions that was in the box did not contain the part of the manual switch – printed in red.
    The bypass could be installed provided that you make use of a two throw switch which would prevent the backfeed on the live wire.

    I am trying to understand the use of wire connection point 3. Is it a “blank” connection point or for what is it used?

  12. david said on May 24th, 2012 at 3:49 pm:

    Just checked ours. Ours is blank. The neutral comes directly from the DB.
