Replacing APT timer with Flash timer

Johnny Bitte

Hi All,
Hoping someone can help me with this as I'm stumped.

A couple of weeks ago our APT heating timer stopped working (the clock no longer turns)

Bought a Flash timer today as I ve been told its a straight swap.

Now there appears to be some difference to the wiring and can't figure it out.

The APT, has 3 inputs where all the neutrals are together and the live are in the other 2 along with the black???

Any help would be great

live input(2 on apt timer )into 1
neutral input into 2 (see can you use neutrals off the same cables as above)
live out (1 on apt timer)into 4

make sure power is off

Those APT timers seem to be very troublesome. The fact that they're everywhere doesn't help matters either

I've replaced numerous APT timers troughout the years. they seem to be a disaster. I always use the Flash timers. never had any problems with them:)

ya.the failure-rate is high alright with the apt.They're convenient to wire, if only they'd stay workin!!

Hi

I'm looking for help with the opposite of the OP.

Our flash heating timer clock has stopped working and i have an APT to replace it with.

The flash has 4 inputs - live in(1), netural in(2), netural out(3), live out(4)

The APT, has 3 inputs live out (1), live in (2), netural (3)

What is done with the two neturals do they both go into the netural input in the apt? Any help appreciated.

Many thanks

yes the 2 neutrals are connected together. this is why the flash is better, because it is double pole where the live and neutral are disconnected when it switches off (eg a shower or cooker switch). the APT is single pole ( only the live is disconnected in the off position.. just like a switched socket).

The Flash isn't a double pole, there is a link between the incoming and outgoing neutral connections afaik.
What is true though is that the Flash seems to be better than than the APT and cheaper too, in my local wholesaler

we sell both apts and the flash equivilent. we sell prob twice the amount of apts as flash and we get back way more faulty apts then flash. there is a newer upgraded version of the apt out now and its offered with longer warrenty then the old, its also a bit more aesthetically pleasing to look at.
