Another occasion is in the bathroom when I open the window to get rid of the fug that is clouding the mirror. the cold air causes it to display ‘window’ and set to 5 degrees, for 30 minutes.</div><div class=""><br class=""></div><div class="">Both of these examples are entirely correct and makes me think the Evohome system is well designed.</div><div class=""><br class=""></div><div class="">I recommend you buy an Evohome system and install it in your house. You will then understand what you are up against.</div><div class=""><br class=""></div><div class="">Regards,…………..Chris.</div><div class=""> <br class=""><div><blockquote type="cite" class=""><div class="">On 27 Jan 2017, at 17:29, Damon Hart-Davis <<a href="mailto:dhd@exnet.com" class="">dhd@exnet.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div class="">Hi,<br class=""><br class=""><blockquote type="cite" class="">On 27 Jan 2017, at 16:27, Chris Skerry <<a href="mailto:angela.skerry@gmail.com" class="">angela.skerry@gmail.com</a>> wrote:<br class=""><br class="">Hi,<br class=""><br class="">I have your competitive product - Evohome. <br class=""><br class="">In the early morning I can hear a little whirring noise, followed by the noise of pipes expanding against the joists. <br class=""><br class="">Its not obtrusive, and usually I am asleep.<br class=""><br class="">One thing the Evohome TRV does is to shut down to 5 degrees if it detects a sudden drop in temperature = door or window open.
