Fibaro Heat Controller and Heat Activator not working properly

[marlo 2]

I'm new to the Fibaro system but I'm quite disappointed. The problem is how the Heat Controller works. I have installed this heating system on one floor of the house and I also bought it on the other floor but I don't know if I will install it for these problems. I'll probably sell it because it's a disaster. I expected better software processing from these systems. Fibaro presents itself as a top on the smart market, but my disappointment is great. With such a large financial investment.

Issue # 1:
When I set all heads to OFF, sometimes the Heat Activator does not turn off because some heads still make a request for heating even when it is turned off. Check image:

Issue # 2:
When I return all the heads to the weekly plan, sometimes some head does not take over the temperature from the weekly plan but sets a different temperature I don't know how. I will solve this only by manually setting the given head to a certain temperature and then returning it and then it will take over the temperature from the weekly schedule.

 

Issue # 3:
The hysteresis on these heads works strangely.
When I have set the temperature to 21 ° C, the hysteresis is about 2 to 3 ° C, which means that when it reaches the desired temperature, then it regulates only in the range of 19 to 20 ° C and does not reach the desired temperature.

 

Issue # 4:
The graph of temperature and setpoint temperature shows values that I do not understand.
When I have set the temperature to 22 ° C, the request is drawn in a special way and shows the desired temperature of 22.5 ° C. Even when the head is off, the setpoint is displayed in the graph as a temperature that is not even in the weekly schedule.

One more question? Does anyone know what this graph is and why it can't be displayed?

The problem is, this does not work. I have 16 of those Fibaro Heat Controllers and usually at least one of the has "heatRequired": true even if the demanded temperature is lower then current temperature (e.g. demanded 10 °C, current 17°C). The other problem is the Heat Controller is often closed when "heatRequired": true so the Heat Pump is working against a closed valve.

Interesting... from my observations I can say "heatRequired": true works quite properly (if true, then valve is usually opened), but I'll keep eye on that. Anyway it looks like neither hysteresis, nor "heatRequired": true "heatRequired": true is ultimate solution, because both of them can be broken and over/underheat boiler 🙁

 

PS: In parallel, I bought few Eurotronic Spirit Z-wave heads and testing them with the intention of getting rid of Fibaro Heat Controllers.

For example now:

 

Current temperature: 21,2 °C

Demanded temperature: 20,5 °C

heatRequired: true

 

This is the better case. Sometimes there is heatRequired: true for those with demanded temperature = 10 °C and current temperature around 18 °C...

Hello,
Is there already an effective solution that solves the above problems?
The second issue is whether the thermostatic head can be paired with the temperature sensor in the motion sensor? There, too, there is a measurement of tempreature and the location is usually better. Is only a dedicated sensor an option?

Up. 🙂

Hi, I just downloaded your QA for testing.

Looks it works great.

I just have one small question - for now it shows on dashboard generic icon (box with ? mark), so it is hard to tell if heating is active or not.

Is it a way to have a heating status displayed somehow on this icon on dashboard?

That is indeed what I have seen. The heatrequired parameter was telling the system it requires heat, but the valve was closed and the boiler simply kept on going.... good to have at least 2 heaters without these valves so it can flow. But I tell you.... it got hot!!!!!

With this solution above, I never got into that trouble even since. Works like a charm!!

The overall heating logic behind these Fibaro radiator heads is somewhat disaster..Either nobody knows how they work, what is the hysteresis behind it, or it just doesn twork at all. Not opening the valve when it should and vice versa.

I am just wondering, why not a single response here from any Fibaro developer..

Hello everyone,

 

I'm bringing up the subject, I got trapped like everyone else, and in 2024 it's still not resolved, it's a disaster...

At home the problem is that the heat activator activates and deactivates every 5 seconds the contact of my heating system, I called the output “TEST” and activated the notifications to see how it reacts and it's clearly bad.

 

Have you had any feedback since?
