Hello,

we have an outside temperature of 24 degrees. However, I want to turn on my air-to-water heat pump to dry a very small moisture damage in the bathroom floor. A joint was slightly leaky.

I have increased the outside temperature limit to 30 degrees (maximum). I have also raised the comfort temperature of the heat pump for indoor spaces from 20 to 30 degrees. I have increased the heating curve from 0.2 to 1.0 (maximum). The Taco setter valves are open, meaning there is flow. I have disconnected ERR after the thermal balancing.

However, the pipe in the underfloor heating manifold does not even get hand warm.
What else can I adjust here to get a bit more power into the system? The bathroom has become 2 degrees warmer since Monday. I suspect this is rather due to the outside air. The floor in the bathroom feels neither warm nor cold.

How about simply setting a constant flow temperature? Every heat pump should be able to do that, similar to [Estrichtrocknung].
