G'day Vern,

This product has been discontinued for a number of years now so I can't speak from personal experience unfortuantely, however I did find a copy of the instruction booklet online. My best advice would be to make sure the units are close to each other (within 100m), and then maybe to take the batteries out, wait ten seconds, and then put them in again, ensuring you do not press any keys until they have connected, as this will intefere with the connection process. 

Hope that helps!

G'day Martin,

We havent stocked these for years, and they are now discontinued, so I'll do my best to remember!  I believe its dependant on the clock setting. The 24hr time automatically defaults to Fahrenheit, whilst the 12hr time automatically defaults to Celcius.  You should be able to hold down the "Set" button to cycles through the different clock options.

G'day Peter,

The Wireless Fridge Thermometer and Clock only displays the temerature but can't actually control the fridge sorry. 

G'day Garry, 

I've just spoken to Evakool, and they've told me that the Wireless Fridge Thermometer and Clock is designed to be used with just one unit at a time.

If you use it with two units side by side it will only read one of them, and it's likely you're not going to be able to tell which if that makes sense.
