Geyser timer replacement question

[yousuf2217]

I'm replacing my current geyser timer (which is a MajorTech MTD8), as the internal battery no longer works, and doesn't store my settings after the power goes out.
I've purchased the following new timer to install:

WiFi Smart Timer & Electricity Meter TWSTM2 (911-02016)

911-02016

It was quick job replacing it as the wire setup was already there from the previous timer, however, I just have a question on the 'bridge' that was wired between the Live-in and Live-out ports on the old switch (see attached diagram of the manual of the MTD8).
What is the purpose for bridging these 2 ports? And should I be bridging the Live in and out ports on my new timer as well?

Just chuck it in the bin, there is no point in having a timer. Get an electrician to do the wiring for you.

If the IN and OUT were bridged, then the timer would have no function
The timer is a switch
On = IN and OUT connected
Off = IN and OUT not connected

Wiring is straightforward. You combine the neutrals, that is all

A Geyserwise is a better device for your application, and much more flexible. About R1200

but it's just the live that's bridged?

thats not a bridge as in a bypass.your top contacts only supply the timing circuit ,to get power to the relay, you need to put power on the common at the bottom and use either the N/C or N/O contact.in other words your switched side of the relay could switch any voltage aside from mains .6v 12v 220 v etc

not a bridge as in a bypass its just an indication of how to get power to the common on the relay .

IE you could put a lamp on 3 to show you when the geyser timer is powered off to the element

Technically by law you not allowed to do that wiring yourself unless you can provide a coc for it

nah.people misread sans 10142 .to many people get conned by unscrupulous sparkys because they dont know the regulations .you only need to update your c.o.c if you have extended or rewired or added onto a circuit and only then do you c.o.c the additions .by changing a timer or socket outlet you arent modifying anything .we would be very rich if it was infact such and pool companys would make a killing as well as plumbers when they replace an element

also when you do a c.o.c you have to disconnect or remove lamps .elements .timers etc because the testers will blow the circuits inside .

I took battery out, wire new one out side, working like a dream.
