Got myself a programmable TRV, first impressions

vvzzvvzz Member Posts: 39
So I recently discovered that Danfoss makes a programmable TRV head. I have a constant circulation system with regular mechanical TRVs. I'm not a huge fan of Nest style smart thermostats (especially since they are usually installed on top of antiquated system controls) or systemwide setbacks, but I do like to sleep at around 60 degrees.

I don't think they are officially offered in the US, so I got one off european eBay. It's called Danfoss Living Eco:

It includes RA mounting adapter which goes right over regular danfoss valve body. It came with two basic programs(one with just night setback, and one with night+workday setback) Those can be changed but I didn't even bother because the defaults work well for me. The whole install took less than 10 mins.

The plastic housing feels kind of cheap, but also it's one of those set and forget things. The unit works well and seems to do a good job maintaining the programmed temps.

    What kind of batteries does it use? How long should we expect them to last?

    It takes 2 AA batteries. I think manual said they should last for over a year.

    Is it quiet?
    I have a Caleffi and Heimeier and they both have a fairly loud gear train noise. They act as a setback TRV and alarm clock!

    Seems they all read metric units only, too.

    It's definitely audible, but didn't seem bothersome. I live in a city though, close to airport, so my noise tolerance is high.
