Thermostat or Danfoss Living Connect

Other Devices & Integrations Climate Control & Temperature Sensors
1

Hi,

I am new in buying z-wave devices (as you may have figured by my so many questions in this forum). In my apartment, I have 3 rooms, each with a radiator, and in the main bedroom there is an analog thermostat, that controls the temperature of all rooms that have the radiator opened.

  1. I wanted to know what recommendations (pros-cons) there was, in buying 3 Danfoss Living Connect, so I could control each radiator vs changing my analog thermostat with a digital z-wave thermostat.

  2. Are both products dependent on each other, or are they one or the other?

  3. Is there any technical detail I have to be aware off when looking for thermostats or danfoss products?

Thanks in advanced.

If you do a search on the forum, there are lots of comments about the Danfoss (including from myself), there are quite a few issues which you should read about. I think these issues might have been solved with new firmware but I am not sure.
To the general question, I have a similar setup although in a house (which should not make a difference though), I have a main thermostat, which I have replaced with a zwave one. That turns the heating on and off, I generally leave it at one temperature when the heating should be on, and a very low one to turn the heating off. I then use my radiator valves (I use StellaZ, again you can find a lot of information on those too on here) to turn my rooms on and off. I find this setup works very well for what I want to achieve. But as general as you have posted the question it is hard to give you more specific advice. You should post what you actually want your system to do. You might not need all the rad valves, that all depends what your setup is and what you arte trying to do. So a lot more information needed.

Thanks mikee123!

In your configuration, I understand the use of the Thermostat to control all rooms, but the StellaZ in the radiators, do you use them independantly from the Thermostat? Or is it used when you only want to control individual radiators and not the full house?

Basicly my question and my doubt is regarding using thermostat+radiator valves or just thermostats? The uses of Danfoss I have already read and understood.

I use the thermostat to turn on and off the heating. Some rooms, hallway and porch for example are always on (when the heating is on). I use the rad valves to just control rooms better. For example my living room does not get used during the day, so even with the heating on, the living room rad valve comes on about 1 hour before i come home from work (automatically via a PLEG schedule with manual override). The kitchen rad valve is on all day, but after we had dinner and when my wife is finished in the kitchen i manually turn off the rad. My study is another room which is off all day (again all of those have a manaual override) and comes on for 2 hours in the evening . So i have schedules for many rooms, which are basically heated independent from the general heating. So even though the house heating is on, only the rooms i need to be warm are being heated. That should save some energy i think as you are not heating the whole house but just the rooms you use. And this is all fairly automated via PLEG schedules and some more logic, and all with a manaual override, i use a multiswitch for all my rads where i can see if they are on, and i can turn them on/off manaully as well if desired. I turn of the house heating (main thermostat) automatically when we both leave the house with geofencing. So possibilities are endless.

Thank you again mikee123!! Very clear explanation! now I understand the uses of thermostat nad/or rad valves!!!

That georeference is one thing I want to learn more about (will be looking in the forum for this)!!
