I have the same issue with the bathrooms: "Bathroom is cold" "No it's 20 degrees in there" "The floor is cold" "That's because it has reached it's temperature and the UFH has turned off" 2 Link to comment Share on other sites More sharing options...

Do you have a model number? I will try and dig out the paperwork, I don’t think it’s changeable, also it’s not a dry contact type and I blew the ASHP main board so modified it to dry contact.

joe90 Posted February 7, 2021 Share Posted February 7, 2021 @ProDave it’s a Wunda wired stat, can’t find any instructions or spec on their website, might give them a call in the morning to see I can get any info from them. Just found another stat (spare from electric UFH) again with no instructions or box ?♂️ (It is dry contact tho ?). Link to comment Share on other sites More sharing options...

The duty engineer says "I'll put that up 2degC, doing it as we speak, I'll phone you in half an hour". Half hour later he phones back and the tenant thanks him, much warmer etc. Truly impressive as he hasn't even touched the BMS computer to do it ? 1 Link to comment Share on other sites More sharing options...

Bramco Posted February 8, 2021 Share Posted February 8, 2021 22 hours ago, joe90 said: my stat has a 3’ hysterisis , means it switches when 3’ difference is felt. Set to 21’ it switches off at 22.5 but switches on at 19.5, really need to find one that’s got a 1’ hysterisis I know @joe90 has worked out how to set the hysteresis on his stat to 1' but ..... What simple stats are out there without all the programmable stuff which have 1' or lower hysteresis. Just simple old fashioned stats.
