Air-water heat pump current consumption and data

No. That depends on the installed heating circuit distributor and not on the actuator. It only presses the "Pinöpel" for open/close.

By the way, today I looked at the datasheet of my actuators for fun. Operating power 2W, which would mean 42W standby consumption over the whole year for my 21 heating circuits if I turn all thermostats to MAX. They actually get much warmer in the open position than my heating circuits.



Quick measure is now to turn all thermostats to frost protection=MIN and set the actuator manually to open. I will observe the standby consumption of the house when the heat pump cycles again.

I also have the same actuators. I only have 13 heating circuits, but I also turned the ERRs in the rooms way down to frost protection and set the actuators to manual. The actuators no longer get warm like before.

However, with some valves, you can adjust how far the actuator opens and how far the pin sticks out.

Actuators no longer get warm like before.

I would even go so far as to claim that they get at most as warm as the connected HKV.

I don’t understand how there can be a review in the big flow about these parts that praises the normally closed position.

With some valves, you can adjust how far the actuator opens and how far the pin sticks out.

But not with this actuator. It can only be open/closed. And to adjust the flow in the open state, you then need the sight glass or the "number of turns," although the latter is, in my opinion, real botching. The flow also decisively depends on the heating circuit behind it. Long/short, narrow/large bend radii, pipe diameter, etc.

How can I adjust the liters of the heating circuit here? Where do I have to turn?

Looks like a Logafix heating circuit distributor from Buderus. There are data sheets available on the internet. But you can also clearly see that your heating technician was just "too lazy" to install/buy the sight glasses.

I correct myself, it apparently can actually be bought that way. However, I would be very surprised if on your HCD a blind plug would not simply need to be unscrewed to retrofit the sight glasses.

PS: Sorry for the formatting, I'm too lazy to figure out how to change it after copy & paste ;)
