All tstats I've seen had installation instructions.
I'm not sure of the color, but 2 of the wires are in, and 2 are out on the tstat. It should say on the tstat itself.

The in (line) wires connect to the source conductors. The out (load) conductors go to the radiator). The supply has to go from the breaker to the Tstat, then to the radiator. If the supply goes to the radiator first you will need 2 12-2 lines between the radiator and the Tstat.

I assume we're talking about a 220V radiator, a 2-pole 220V Tstat and of course a 220V supply (2-pole breaker).

Please confirm what you have first before you start anything. You don't want to short a 220V line.

Thank you trinitro for prompt reply.
I am relocating used thermostat. Previous connections had other baseboard heaters on the circuit. Now i will have only one heater (2000w).(220v)
I am assuming that power source will be connected to one side of this 2 pole tstat(one black and one red wire). I will join wire from rad to the right side of the tstat ( the other black and red wires)?????

Almost. The line connects to either the black OR the red wires on the T-stat. Not to one of each. I believe the black is the line, and the red is the load, but double check the writings on the Tstat.
