ᐅ Heat Pump in the Shoulder Season

Hello, I have had the Weishaupt split heat pump LS 8 B R E since July, so far only used in summer mode. Today I switched it to heating mode, and the heat pump cycles on and off 6 times between 4 a.m. and 11 a.m. What options do I have to reduce this cycling?


Diagram of a heating system: flow rate green, supply yellow, return light yellow, modulation red.


I am new to heat pumps. It is a 120m² (1,292 sq ft) mid-terrace house with 9 radiators, no buffer tank installed. What settings can I use to minimize the heat pump cycling? What settings do you use in the transition period? I would appreciate any tips.

Best regards

The value can probably be configured with "HeishaMon".

That’s like retreating to your electronics workshop to build a circuit board and write your own scripts to fine-tune the ignition timing, fuel injection amounts, etc., on your brand-new car so that it runs more efficiently than the factory settings.
Of course, you can do that, and it’s certainly a cool hobby, but it doesn’t really help if these fine adjustments don’t save you money or extend the lifespan.

I prefer to focus on proper planning and then operate a well-configured automatic system for the next 20 years ;-) (and Pana actually does this really well)

Update: I switched on the heat pump yesterday evening around 10 PM, as the outside temperature had already dropped quite a bit in the previous days and the indoor temperature was only 20°C (68°F). The Pana has operated exactly two cycles since then: one lasting 3.5 hours and the other 2.5 hours.

And how warm is it inside now?

Just under 21 degrees Celsius (70°F) – overall it feels better around the feet.

That’s why I never understand all the heat pump setting threads here in the forum. What the German manufacturers have come up with is baffling to me. Foreign (Asian) devices are much simpler. Over there, nobody wants fluctuating temperatures, heating integrals, standby modes, cycle locks, and so on.

You speak my mind. I am in AUS and can also buy German heat pumps. I was shocked by the operation manuals—millions of settings. I don’t want to earn a degree in heat pumps. That was the sole reason I didn’t buy a German product. And the forum confirms how overwhelmed the pump owners are. We have an Asian device that is the most popular here. The company runs a blog, and questions are answered more or less immediately, 24/7, top-notch service. The company we bought from also replies on Sundays (family business). If I wanted the top tier, I would buy a Japanese unit here.
