I assume it's not a freezer.

So, you set the thermostat to +5 degrees for the fridge interior. This means when it's 6 degrees or more, the compressor will come on.

Now comes the stupid part:

When it's 4 degrees, the compressor will NOT come on.

When it's 0 degrees, the compressor will NOT come on.

When it's -100 degrees, the compressor still will NOT come on.

Time for some lateral thinking here!

If you put a big electrical heater in the fridge interior, then the compressor will run!;)

Do I get the prize?

OK then, what if I was to change the thermostat to a freezer one?

And if the outside temp was below 0 deg Fahrenheit I would use additional heating

No, trigger point of 5 degrees CENTIGRADE is correct, but you want the relay to MAKE contact below the trigger point. The freezer thermostat will make contact when it's warm, like 15 degrees.
You don't want to heat the shed when it's nice and sunny outside. What you need is a frost stat.

Tower RFS Frost Stat - STTRFSN
Thermostat for frost protection - SPST

* Range: (-5degC to +15degC)
* 10a resistive load (2a inductive) at 240VAC.
* Accelerator heater.
* Neon Indicator.
* Single Pole - Single Throw.
* Differential 0.5degC.
* Surface Mounting.

just a thought, years ago, I had to make a heatbox for a welder, to keep his welding rods dry, I wired two lampholders and put two 60 Watt bulbs inside a metal box, the box had a vent across the top and slots to both sides to allow air movement, it was left switched on inside a site shed overnight and during the winter heated the shed sufficiently...albeit for workmen, 120 Watt heater.

If you put low energy bulbs in that would be even better ( In comming!!!!)

Best thing is, if you leave the door open in summer, then it will cool the shed too!!

How to keep the chill of your shed during the colder months.
Find an old fridge.
Cut a hole in the side of the shed the same size as the fridge.
Install the fridge with the rear facing into the shed and seal any gaps.
Remove the door of the fridge.
Ask a qualified electrician to bypass the built-in fridge stat and install a room thermostat inline on the powercord and secure to the wall well away from the fridge.

PLUG IT IN (via an RCD powerbreaker plug) ! Voila!
Optimal settings can be found using the room stat and will ensure the fridge motor does not experience more prolonged running than in normal surroundings.....SIMPLE !!!

Problem with that is the Compressor will cut out on thermal overload.


By-pass the thermal cutout.....compressor goes BANG!!!!
