I lived in Amman for awhile...from what I hear, it has grown considerably since I left. Around the 8th circle, it was still desert and Allia had not opened yet (but was almost done).
Most thermostats here are designed for 24vac. There are some that will work on higher voltages. You need to determine what voltage is being switched, then you'd have a chance of picking one that should work. A thermostat is basically just a switch, but you need one that can work at the voltage and current needed at the switch. You may need a line-voltage switch (which would be around 220vac). The voltage was very volatile when I was there, fluctuating radiacally.
If you are handy, you could use a low-voltage thermostat to control a contactor or relay if it is switching much current rather than trying to find a thermostat that would work. Depends on what's available.
