However, one of the OpenTRV equipped radiators (rev 1 + Conrad actuator) stays stone cold despite the valve claiming to be open at 60+. All other OpenTRV equipped radiators are fine.</div><div><br></div><div>So the question is: how do you identify the root cause and fix for such a problem? Could it be due to the valve having somehow been de-calibrated during the summer while it wasn't in use?</div><div><br></div><div>As far as OpenTRV is concerned, there are a couple of things that we could do:</div><div>- add something in a FAQ to explain how to analyse such problems</div><div>- automatically re-calibrate the first time heat is required after a long period of inactivity or do so regularly (of course assuming the root cause is a calibration one)</div><div><br></div><div>Thoughts?</div><span class="HOEnZb"><font color="#888888"><div><br></div><div>Bruno</div><div><br></div></font></span></div>
