Heating Panel with Danfoss not working

[rog 2]

I am going crazy. I have two Danfoss Living connect valves as I want to test what is possible with them.

Now, I could easily connect them to a room. I can control them via the Devices panel. I can set the target level via LUA (and get it back). Everything works fine.

So, I created a heating panel, added a zone and the room of the Danfoss valves to the zone and guess what - nothing happens.

If I use the manual setting in the Heating Panel, nothing happens.

What do I do wrong?

That should work. Maybe this is a bug...

In version 3.6 I never had issues with Heating Panel. When I upgraded to version 4.x I had problems and couldn't adjust the temperature manual by thermostat anymore, it was overwritten by the heating panel/

That's why I created a scene to set my temperature and schedule it. I never used the Heating Panel in 4.x anymore.

 

Edit:

I see there are some more with problems. There is a bug filled for that.

The one thing I think most of you are misunderstanding about the Danfoss devices is that they are "thermostatic radiator valves" - they are not a "thermostat". In other words - you cannot use it to turn the heating on or off; you can only use it to open or close the radiator valve depending on the configured temperature. Unlike a thermostat, the Danfoss device also does not report back the actual room temperature. So it is really one-way traffic on that front.

 

The configured temperature can be set via the heating panel just fine - but the Danfoss is a pull-only device, so you have to wait for the Danfoss to "wake up" and collect the new temperature setting from the HC2. You can fine-tune this by configuring the "Wake up interval (s)" value on the "Advanced" tab of the device in HC2. A wake up interval of lower then 300 (5 minutes) will drain the battery really quick.

 

You can use a scene to detect when the configured temperature on the Danfoss was modified and then turn your heating on or off based on that - but without a temperature sensor in the room you will not be able to detect when the room is warm enough.

 

In my personal opinion the Danfoss devices are also a bit problematic to use as a way to set the desired room temperature because typically your radiators are not very well positioned for easy access. So in the ideal scenario you have a Danfoss valve on every radiator in every room and a Secure SRT-321 room thermostat in every room as well. You will then still need to do a fair bit of LUA coding because although you can create a nice heating schedule via the Heating Panel, the Heating Panel cannot properly control a single boiler when there are multiple rooms that want to turn the boiler on or off independently of each other. You may find that one room turns the boiler off while the other room is still not warm enough...

 

Getting this to work is a lot easier when you have a couple of Fibaro switches available that you can use as "dummy" devices - in that case you can add multiple linked devices, one for each room. Also in that case you will still need some LUA code to manage your single boiler.

I disagree with the main point of martijnt. The best solution is to use a Danfoss LC thermostat in every room. Set the boiler to a fixed temperature, or use an outdoor probe to adjust the water temperature. Do not use a "main thermostat". The main thermostat and the individual thermostats will "fight each other". Several topics exist, so I am not going to repeat. And though there may be not a consensus, I have tried all different setups and using and "outdoor probe plus no main thermostat" gives me the best comfort level of all setups. And no lua coding needed.
