Replace Thermostat

Hi,

I have a bottle cooler (FOGEL) with a Danfoss ct-35-d thermostat that is not working.

I got a replacement TGM K50-T1127 thermostat. Should work fine. But only one little problem, the wires were removed without me seeing how they were connected.

There are two red wires, one white and one black. On Both thermostats there are four pins. one stating #3, one stating #4 and two other pins without # that are one and the same for they are part of the metal casing of the thermostat. I know that the red wires control the compressor ,the black and white are the electric fan that circulates the air inside.

PLs. advise on how to connect the wires.

Thanks in advance.
