ᐅ Heat Pump in the Shoulder Season

They charge ongoing fees for that? 😱 😳 🙄 🤨 😡

They do have to continuously provide cloud services, updates, and so on.

Starting tomorrow, the temperature will drop. What can I adjust so that the heat pump doesn’t cycle on and off so often even at around 12°C (54°F)? Increase the supply temperature? Raise the room setpoint? Extend the minimum run time? Or simply set fixed heating periods?

Just stay relaxed. At these outdoor temperatures, it takes a few days for the house to cool down enough for the heat pump to run proper cycles. Depending on the heat pump, there’s usually not much you can do. For example, my unit doesn’t even have a minimum runtime setting. I still have 22.5°C (72.5°F) inside without heating. So I’m planning to keep the heat pump completely off until at least the middle of next week.

Hello, since yesterday afternoon I switched the heat pump to heating mode, and it’s cycling very frequently, see the attachment. I set the quiet mode from 9:30 pm to 7:00 am at 75 percent. Target temperature is 21°C (70°F) at night, frost protection at 3°C (37°F), one defrost cycle. The heat pump runs about 35 minutes then rests for about 30 minutes. All radiators are open. There seems to be a lot of room for improvement regarding the cycling. Does anyone have tips?

Why my posts containing important notes and questions were immediately deleted, of course, no one will explain.
Questions to the OP:
Why is it set so warm? Is this an existing building where the heat pump was retrofitted?
I find the cycling time just about acceptable, but the fact that it starts up again so quickly is rather unusual.
Do you find any hysteresis point?

Just reading settings like "standby mode 75%" makes me feel uneasy. Why do most heat pumps have such ridiculous controls? (The Vaillant thread with 529 pages is also incredible).
Sorry, I can’t help you there. My heat pump doesn’t have any of those settings. Panasonic models are much simpler and don’t have such unnecessary options.

BUT: Given the current weather conditions and the remaining indoor temperature, your heat pump is still producing too much heat. In other words, the house hasn’t cooled down enough yet. Also, if there’s some solar gain through the windows, it will take even longer for the heat pump to run smoothly. The still relatively mild daytime temperatures aren’t helping either.
Just let the heat pump run from 5 a.m. until 10 a.m. and not at all during the rest of the day.
