For my woodworking shed I would like to measure the outside temperature and keep the inside temperature 1 degree above (the outside tempurature).
For example: when the outside temperature is 5 degrees, a heater must increase the inside temperture to 6 degrees and then stop heating.
Cooling is not important as long the inside temperature is higher than the outside temperature.
Can I achieve this with the STC-3008?
Thanks for ypur response!

Hi Khalid,
This depends on what you mean. Do you mean a fridge with 2 different temp zones, like a domestic fridge where you can set the fridge temp as well as the freezer temp separately? Well first you need so find out how those 2 temps are effected. E.g. some big fridges have 2 compressors running independently, then it is easy. Others have 1 compressor, and a valve that sends coolant to 1 side or the other. Now you need to figure out which way it goes when the valve is not powered, so that you can determine how to wire it up. One thermostat will typically control the compressor, and the other the valve. But in that way when the valve goes on because that side needs cooling, nothing will actually happen until the other side also needs cooling and thus switches on the compressor. This can be solved with simple use of a basic relay so that both thermostats can switch on the compressor, but only one also switches on the valve. Hope this makes sense

Please see the last sentence of my comment below

I think the explanation of the temp setting can be simpler (but I must still refine that simpler explanation). I understood the device by reading the Chinglish & playing with it.
This unit is great as a replacement controller in camping fridges with dual compartments (with no space for 2 single controllers).
But the way of setting the temp is a bit odd and also makes it easy for an owner to mess it up, accidentally end up in heating mode, and not understanding what is happening.

I would like to add:
Press the 2 Up Arrow simultaneously for 3 seconds: Enter the Setting Mode as in the manual (and on this page)
Press the 2 Down Arrow simultaneously for 3 seconds: Reset the device & all settings as on this page
Press the Up & Down Arrow of 1 side simultaneously for 3 seconds: Enter a setting mode for calibration of the temp reading on that side.

Regards
