Replacement for ancient boiler timer

carveone

Hi all,

My parents have an gas central heating system which consists of a big cabinet made in Germany somewhere with a separate pump. There are two power leads to two plugs switched by an ancient Venner timer. I say this because I'm not sure how much current this thing needs to switch!

The Venner has given up the ghost and I'm wondering is there a recommended replacement. The Venner had two on/off periods controlled by tappets around a moving dial. Simple to use and set. More importantly, simple to override with an on/off switch - switching it on would stay on until the next off tappet switched it off. That way people don't forget and leave it on.

The electronic ones seem a bit complicated and I'm not sure can they switch the required load (I should find out I suppose). In my place, there's a APT mechanical timer switch which does the job pretty well other than not turning itself off. Are they still available?

Thanks.

Apt time clocks are still available theyre basic but they do what it says on the tin

But an apt clock wont switch off automatically when in overide which is what your looking for right??? You could put in a basic switch beside the apt clock for overide purposes instead of using the built in function on the timeclock and just connect it to a standard timer module which can be set to whatever you require. Sounds easy enough and bullet proof to use once the timer is set to the maximum overide time. Somebody else might know of a better way here without using the (complicated) electronic clocks which can be very troublesome for the older generation!!!!

I replaced my apt timer with a seven day, twice a day electronic switch, with a one-hour boost. Getting the wiring right was the challenge as the instructions were poor

If you want something simple to use with a hourly boost feature I'd go with the horseman c11 , it's digital but a very simple , basic time clock . Cost about 60 euro-ish

Thanks for the suggestions. There's the Horstmann 425 in there too which might do the job. I'll see what they're comfortable with...
