Hi i know grazzlin do a 24hour timer and every white switch is 15mins.
But what i am after is a timer with minutes an seconds.
So for instants i can set a machine to run for 20mins and defrost for 30seconds,and repeat this.
Do such timers exist?

You will need a microprocessor-based device with a change over contact that will operate two relays, one for the defrost and another one for cooling through a thermostat contacts.
BTW, its grasslin and now it called Itermatic.

I'm an Ex-fridgie and new to air con but I have never seen so many dead timers, Grasslin timers, can't be programmed and won't hold information. I suspect the batteries are dying. Is anyone else having the same problem??
