Immersion heater timer

[F]

No, I simply didn't want to be heating water in the middle of the day and during the night when we wouldn't use it.

[F]

He called here earlier but I had to disappoint him. He wanted two and I only had the one.

What timer did you buy?

I have fitted so few that I cannot give a recommendation. The ones I have fitted have been awkward to fit but seemed to have worked well.

Now what is the difference between these two

Volt Free contacts :-)

I haven't found one yet so have been using one of my existing electronic switches (bearing in mind earlier warnings about the plug/socket contacts).

The second , more expensive, one is a 'General Purpose Timeswitch c/w Voltage Free Contacts' and 'Switches up to 750W incandescent or halogen lighting/750W fluorescent lighting/100W compact fluorescent lighting (cfl?s). Not suitable for discharge lighting'. There is no mention of this with the other which is described as an 'Immersion Heater Timeswitch' rather than a 'General Purpose Timeswitch

c/w Voltage Free Contacts'.

Does it matter?

[Chris Hogg]

Yes, I read that. WTF are voltage free contacts? Answer here:

A relay has voltage free contacts.

[ARW]

I am hoping that Peter Andrew's :-) was because he was thinking what I was thinking

That are the same thing but one of them has a live connection wire pre installed to the volts free contact.

So, for an immersion heater application, does it matter?

[Andy Burns]

Both models have L-in and N-in terminals, additionally

the T03 model has N-out and SL-out

the T04 model has S-in and S-out

so for the T03 they probably cut one link and adding two others in the factory.

[ARW]

Look again at the instructions for the T04

"The T04 has a wire link in place and this should not be removed"

"Sin (T04 only) if volt free is not required then fit a link between L and Sin"

Seems that the instructions are at home to Mr Cockup:-).

The T04 is in the real world volts free and the T03 has SL internally connected to live.

[F]

So the cheaper one (T03) would do what I want?

Can't have it , it Arked over and and the end result was a flood.
