Fibaro Heat Controller and Heat Activator not working properly

Question

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?

Hi @marlo,

 

Got the same issue's.

Also if the heads are demanding no heat, the heat activator keeps the heater switch on, or after a reboot if I switch manualy set the heater switch to off, it will never switch on again.

I'm waiting for the next update of the HC3. If this next release has no update for the heat activator, I will contact Fibaro support, see what they have to say about this issue.

But good to know I'm not the only one with these kond of problems.

I though about using the heat activator instead of a script that I had running. However, when I looked at which heat controllers it thought should be active - it was much less reliable that a script.
