Hi guys
This is a bit old for me to help my mate out, he has a AMF venner time clock with a F25 stat fitted and wondered what you replace these old time clocks with and are any alterations required with the wiring, i myself have never come across venner time clocks.

Hope you can help
Kind regards
Lrac

the old vennner/f25 stat were common on the old searle evaps.The f25 was a defrost termination/fan delay stat.the venner had a relay that switched the fan.We usually replace the old timeclock with a Ranco or similar timeclock with auxillary contacts for the fan delay. I don`t know of one with a built in termination facility..it is usually by a klixion type switch affixed to a coil.I suppose that an l.p. switch can be wired to terminate defrost and also delay fan cut in.

probably best bet, is to ditch the old and fit an electronic module with all the functions built in..elliwell 971..2 probe.

The best bet is to replace all the controls with an Elliwell or similar with defrost control etc built in.
