What flow temperatures are you currently running?

Is the Apple Watch also hanging on the north side of the house wall? :D

Thank you for the hint. I didn’t know that yet. At the moment, however, I am satisfied with the indoor temperatures, that the interaction between measurement, electronics, and hydraulics seems to work. So actually it doesn’t really matter what the thing on the facade is measuring for now?

Parallel shift should be the setpoint in Sensocomfort when the room activation is deactivated. The standard is 20°C and I’ve increased it to 21°C.

Defrosting is estimated via the Smartmeter. Whenever I observe defrosting outside, I see a drop in power consumption followed by a peak when it overcompensates for the cooled return temperature.

The base load of my house is just under 2kW at these temperatures. Of that, 1.2-1.5 is the heat pump and 250W other devices. So I guess 400W for the ventilation preheating coil.

Edit: please don’t check the math in detail. very roughly ;)
Edit2: according to the Smartmeter at night every 50-55 minutes.

No, but the heating temperature sensor is ;)
Considering it hangs on the north side, it showed quite (too) warm temperatures from the start. Now it’s right :)



Basically, it probably doesn’t matter, but it can’t hurt to set it correctly, right? ;)
At our place, the Sensocomfort also hangs next to the front door, so you get used to checking the time and temperature there. If the latter isn’t correct (for us, as I said, with a delta of 3°), it’s not a disaster but still annoying.



Ah, ok. I hadn’t understood that as “parallel shift” until now. I had previously set it to 21.5° and now to 22°.



I’ll have to take a look too… Thanks.

Very “dubious” values. In warm outside temperatures old building, toward cold then new building. :rolleyes:

You all have new / insulated houses, right? And then such flow temperatures?

I still live in an uninsulated (from the outside) old building and manage with 29/30 degrees flow at currently -4/-5 degrees at night (indoors 21.5 degrees at the moment).
I think it’s actually due to the design with very close pipe spacing. I find that surprising.

Defrosting, by the way, also about hourly.
