Danfoss RET230P Room Thermostat
If you just want a replacement thermostat without wireless control then i highly recommend this one.
its modern and clean with a slightly retro look about it.
installation is easy, i replaced an old 2-wire Sunvic mechanical thermostat so live went to live and the old return to NO, then its just a case of providing a link between live and common and adding a neutral, easily done by using 3core cable, took me about 20 minutes, although fitting 2 wires into the live terminal was a little tricky (a secondary terminal for the link would have been ideal but you could provide this outside.
its an electronic thermostat so uses a little PCB with a thermistor instead of a bimetallic strip, should be more accurate.
also has an internal relay for switching which gives you the comforting 'click' to know its actually working
its also class 2 so no need to provide an earth.
highly recommended :)

Another incorrect spec - 3A
As per the Siemens model also being incorrectly listed as 10A, this RET230P model is "3(1)A" rated, not 10A as listed here.
see the instruction manual hosted on the screwfix site !
