Hortsmann HFT4 Mechanical Room Thermostat
Maybe a one off...
Installed and working in a few mins.. used this in a holiday unit to prevent tenants over adjusting the temperature fixed to 19oC.. The screws and pins on the unit for adjustment is quite fiddly so i wouldn't recommend to anyone wanting to adjust the temprature at all.. Hoping its a one off as the unit worked fine for 2 weeks then had to call an emergency plumber who found the unit had an electrical fault and was shorting out the heating! hope the replacement lasts longer!

Horstmann Frost Stat
Nicely constructed and tamperproof... Has the lowest temperature range available compared to other manufactureres - so is better suited for protecting boilers in garages without switching on at too high a temperature - as can happenwith the Danfoss RET Frost Stat.
