Climate Controller Heating / Cooling Mode

[Gast]

Hi everyone!

I'm having a problem with my Climate Controller / IRCv2 setup.
The loxone helpdesk told me to contact my installer, but I'm the installer ;-)

I have the following problem:
I have setup my climate controller in Mode 1, which means that it should only be able to heat (see picture).
I do this because, I don't want loxone to automatically switch my heat pump (air - water) from heating to cooling mode, I will set this up manually 2 times a year).


But even so, the Qc (cooling output) is active...

And also on my IRCv2 blocks (which are controlled by the same climate controller), the HC1 output, which I am using for my tree valve actuators, are also active (see picture).

This is not what I expected, and it screws up my regulation.

I can of course use H1 and C1 of the IRC's and throw in some logic together with the Qm (-1 = cooling, 1 = heating), but it's an ugly solution.

Loxone support told me to delete all blocks, and start from scratch, but still the same.

One more nasty thing, which I think is a bug, is the following.
The HC1 output should always be between 0..10 as in the documentation, but sometimes I get higher values. (eg 30, in picture).
I sum all these HC1 values, which in fact corelate to the valve openings, so I can use this total total valve opening value.
I use this value so I can demand heat from my heat-pump only when there is a minimum opening.
If I don't do this, I get the following:
Loxone asks for heat to the pump
My pump tries to deliver the heat, but cannot because there is to small valve opening.
My pump goes in "water flow error" state...


Any suggestions, or am I understanding this climate controller mode wrongly?

BTW: the rest of my system works perfectly, and I'm a happy loxone customer ;-).

Regards,
Tim

Hello, to be honest, I don't understand your climate system. Could you explain what do you want to do? And please, give to us all the parameters of the blocks, maybe is a wrong parameter.
I've tried to simulate your system and everything looks ok. If you want upload the software without ip address and personal data and maybe I can help you.

The last thing, according my experience, it's better buy to a Loxone's partner, because maybe he can help

Hi, I want to control my floor heating, driven by air-water pump, using the standard climate controller, intelligent room controller way.
On every sub circuit, I have a tree valve, and I can demand global heating of my pump.

In the meantime, I deleted EVERYTHING that had to do something with heating, and placed them back exactly the same from scratch.
Now everything behaves as expected...

Maybe it has something to do with the IRC's "learning" and me adjusting parameters...

Anyway my prob is solved.

Thanks!

ok, perfect!!
