12 volt timer for fridge

Rusty ,

I have one on my Autofridge that I bought from - The 12 Volt Shop - at Auburn in Sydney .If you cannot find the number , let me know and I will look it up in the phone book for you .

It lets me put it on for an hour ( or whatever ) in the morning and the same in the evening . It can be overridden easilly .

I kept forgetting to turn it off too .

Cheers ,

Willie .

Hi,
I'm a little confused - doesn't an autofridge have a thermostat which automatically turns it on and off according to cabinet temperature? Doeasn't sound very "auto".

Any large electrical retailer will have 12volt dc 24hour time clocks in their catalouges anfd will be able to order them in.

Thanks, looks too easy-- off to Jaycar for some more spending.....
Gerry-- auto as in automobile I guess. There are 2 ways to operate such a beast. 1) Set the thermostat on (say) 1 or 2 and leave it on and plugged in and this will maintain temp but with compressor running as needed to maintain the "ice bank". I understand this would use some 16>20 ah per day (yes I know this will depend on ambient, load, how many times the lid is open and etc but this is a roughy from what I can glean)
2) Set the thermostat to full on, plug in for 24>48 hours before leaving home to freeze down the unit, then turn on for an hour or so morning and evening (away from peak ambient temps) which rebuilds the "ice bank" to maintain the temp in the cabinet but only draws 4>8 ah per day (same dependencies as above).

Using the first method I can run the autofridge for 2.5 days on my reserve battery(car not running at all), using the second method I have gone 5 days so far and temp inside cabinet <5C at all times. Now logic says to me that the total load will determine when/how long the compressor is needed to run and thus power useage, regardless of the method used. But I know the above results apply cause I have tested them under "controlled" conditions.
