Therefore, I’d be grateful if anyone could point me towards a cheap eTRV device (I’m based in the UK) that I could take apart without horrying too much about wasting money if I brake it. I found the following system which I’m looking at purchasing, but not sure if anyone has any experience with it: <a href="http://www2.westfalia.net/shops/around_the_home/heating_and_cooling/radiators_and_accessories/radiator_thermostats/637720-electronic_radiator_thermostat.htm?gclid=CjgKEAjwtZucBRD77aiiq_v4xnASJABkAg8JWBXgSX6S_EZiV_g24E7HcHxwxTQxhuIW349WnKTI-_D_BwE&art_nr=108555">http://www2.westfalia.net/shops/around_the_home/heating_and_cooling/radiators_and_accessories/radiator_thermostats/637720-electronic_radiator_thermostat.htm?gclid=CjgKEAjwtZucBRD77aiiq_v4xnASJABkAg8JWBXgSX6S_EZiV_g24E7HcHxwxTQxhuIW349WnKTI-_D_BwE&art_nr=108555</a><o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Really, the way I see it at the moment, I only really need a motorised TRV without any real controls, as I’ll be developing an AVR system to control the temperature, but I just can’t find one!<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Thanks in advance for any information.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Steven<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
