Hydraulic balancing, disable single room control?

Oh man, I'd better say nothing about that now...

If the red ring is visible, then the motors are off. However, they may still have power. So to cut unnecessary power consumption, you can later disconnect the entire wiring. But it's best to have someone handle it who is allowed to do so. Electricity is deadly.


Yes, of course. The calculation of the system including the associated flow rates is part of his tasks (or he has to bring someone in if he can't do it himself). Without this, the system is simply not functional and I assume you ordered and paid for a working heating system.

Get the calculations from him or check your house documents; with luck, you have been given these.

Otherwise, prepare for a lot of work and possibly cold or hot rooms until everything is running again.

Writing down is okay, but placing the thermometer in the center of the room and regulating the flow to the desired room temperature and done is more sensible than a calculated hydraulic balancing.

Do you only have 6 heating circuits?

It's not about setting all the controllers to the same value.

It's about giving each room exactly the amount of flow that is needed to reach the desired temperature.

Roughly it goes like this:
Deactivate Err
Turn all Taco controllers fully on
Run 24
Now probably all rooms will be too warm
Now the heating curve is lowered, and only in the smallest step each time.
Wait 24 hours
This process is repeated until the first room is too cold.
Now in the rooms that are still too warm, the flow is reduced in the smallest steps via the Taco controllers until the temperature is correct.
Always only one room at a time and wait 24 hours after each change.

Attention: every change affects all other rooms more or less strongly, so document every step and check all rooms.

WARNING, solar inputs can distort the result.
Therefore, work only under overcast skies and wait for low temperatures so that the heating runs through.

It is simply easier when you already have the previously calculated values and they have been set. Then you no longer have to fiddle around wildly but only make minimal adjustments, and the thermal balancing is completed much faster and more easily.

No, I have 12 heating circuits.

I have attached photos of two HKVs.

Our entire house was too hot and too cold this spring (that's when we moved in)...
The heating curve on the heating system was also set to full blast with supply temperatures of good and bad...
Therefore, I can say for sure, no matter how the Taccos were set... It was definitely not correct
So I prefer to adjust the heating myself...

I also did this with the ceiling outlets of the controlled residential ventilation... That way I know everything is set correctly.

Now I know how to proceed! I will now adjust the individual rooms solely through the flow rate.
If the room should get warmer, I will increase the flow! If the room should get colder, I will decrease the flow.

I will leave the heating curve as it is for now...
