Heat Controller keeps valve closed, but does report heat is needed to Heat Activator plugin

[Mondeo 0]

Hello everyone, I am new here and I have a house set up with a lot of Zwave stuff and recently bought many Heat Controllers.

 

10+ Heat Controllers, one radiator always open (No pressure problem) All works fine when temperatures have dropped significantly overnight. My problem arises when temperatures need to be kept constant. The Heat Activator plugin does switch on the boiler when one or more Heat Controllers demand heat. But when the boiler starts, it short-cycles due to the fact the valve on the radiators do not open. Radiators stay coldish. Not a great situation.

 

Is there something i missed? Calibration problem? (It doesn't show in HC3)

I think this is a general problem of those Heat Controllers. I like them but this is something that makes them not usable.

 

For example now, I have one with the required temperatue of 10°C, the current temperature is 17,7°C, but it reports "Heat Required", the valve is closed and the Heat Activator is on.

 

No solution for months.

a similar problem, 12 heat controllers, fibaro doesn't want to give support

I have similar (and other problems with them) but have another question to ask you for help:

How do you see if the “heat is required” and  what is the status of the valve?

 

i have Home Centre Light and maybe that is why I cannot see it? Or there is a way and I just don’t know it.

Hey Janusz,

 

Devices, advanced section of the Heat Activator Plugin on a HC3. Just doesn't work properly. Somewhere on this forum there are talks about Eventrunner4 rules. Giving that a try. So far not very steady temperature control, but hopefully I will get it working.

 

Status on the valve would be a great thing to know. That would solve a lot of troubles I think.

I have posted some suggestion to similar problems in other topic, maybe you guys can try it too.

Just try to not use requiredHeat property.

Instead check the setpoint and the temperature with dedicated calls and compare the result.

setpoint = fibaro.getValue(raidatoID,"heatingThermostatSetpoint")

temperature = fibaro.getValue(sensorID,"value")

If setpoint > temperature then

..do whatever you want

end

You're correct, I do something similar.

But it's still a work arround . The functionality doesn't funtion. I have car with start motor, but every morning I have to push it to start so I can drive. ?

hello, have you solved the problem? 

 

is there a guide to how to correcly use thermostatic head + heat pump and more thermostats?

 

thank you

I admit being a total newbie on this issue, but can anyone please confirm the status of this functionality?

Hi there,

I have experienced similar problem and posted my experimental Quick App in this post:

It might help resolve your issue.
