Heating control

[biggles 0]

I am trying to get my temperature sensor (Everspring width humidity sensor) to trigger the change of temperature of my water based floor heating, controlled by a Danfoss Living Connect. Tried using the heating panel, but nothing seems to happen. Tried to linked them, but the link can only control, switches. Tried with scenes, but cannot seem to find any commands for changing temperature on the Living Connect. Any suggestions?

Hi!

I am afraid that it will not work like that. You don't need to use additional temperature sensor. Just add Danfoss to some room and create proper heating schedule for zone with this particular room. Danfoss do not need any additional temperature sensor because it regulates temperature by it's own embedded temperature regulator.

The problem is that the thermostat isn't located at the same place as the room it's controlling. Or the thermostat can be hidden behind a radiator cover and get inaccurate readings. Or there are several thermostats in one room which should work together to get the optimal temperature in the room. Danfoss solves this by letting an external thermometer control the thermostas/thermostats. It would be much better if you did the same in HC2. Just add the Danfoss thermostat to the linked heating devices and the problems is solved. If the thermometer shows a to low reading, add temperatur to the Danfoss thermostat. To high? Lower it. Simple as that. Or add the possibility to add a thermometer device to the heating panel and let that one decide how to handle the setpoint in the Danfoss thermostat.

it probably would not work as danfoss has other way of working. i think HC2 sends required temp info to danfoss not tuen on/off command

danfoss does the valve open/close logics by itself

Why not?

Of course the algoritm could easily be a bit smarter, but basically this is what's needed.

ok basically this is to fool the danfoss unit, yes could work that way

I have 8 Danfoss Living connect thermostats and have the same problem as the topic starter.

I want to buy also 8 Aeon Labs 4-1 "Multisensors", and place one in every room where also an Danfoss Living connects is.

Suppose I use HC2 to set the temperature of the bedroom at 20 degrees, then the first thing that must happen is: The Danfoss Living Connect thermostat must be set to 20 degrees by the HC2. (This is no problem).

After this, the Aeon Labs 4-1 "Multisensor" must measure how many degrees the room is.

If the temperature is lower then 20 degrees, the Fibaro 2x 1,5 KW relay --> switches the heating system on.

Once the Aeon Labs 4-1 "Multisensor" measures the temperature in the chamber is equal or higher then 20 degrees, then the Fibaro 2x 1,5 KW relay switch --> turns the heating system off.

Is this possible? Or is there another way to fix this?

you don't need Danfoses. all you need is a temp sensor (Aeon or any other) and then an actuator that will simply open or close a valve AT THE MANIFOLD. you can leave those radiator valves mechanically opened all the time and steer at the manifold.

I don't agree on that, as you than can not set the temperature per room...

for instance I want my bathroom to be 22 degrees between 7 and 10 in the morning. but after that it can go down to 19... in this way you save energy and it's very comfortable.

so you do need the danfoss.

Exactly. That's how I have my system designed. I individually set the temperature and schedule of each room, and then control through the manifold/actuator to action any heat. However, if you don't have a manifold with actuators/valve servicing each room, then this would not be possible and you'd probably have to resort to the Danfoses

[pooh 2]

yeah, you need to have star connection instead of a round robin.

These dont appear to work with the HC2 (yet?), they show up as motion sensors only

This isn't posible for me, I live in Holland where it is normal to have one temperature thermostat in your living room, where you control your main temperature. If you set the temperature @ 22 degrees Celsius, and your livingroom is 22 degrees Celsius, other places in your house aren't heated anymore...

This is an very outdated system, and that's why I thought of the Danfoss / Fibaro HC2 solution.

Yes this is a very big problem! I REALY hope Fibaro will support this sensors very soon!
