I assume you have set the head to 1.7 metres. How did you arrive at this?
Which operating mode have you chosen Δp-c or Δp-v?
Is Dynamic Adapt turned on?
My figure of 1.7 m is the measured height differential between the pump and the highest point of the circuit, the inlet to the buffer tank. Did I need to look at something more subtle?
I have not actually set this into the Wilo settings because if I do, my DT shoots up even higher and I eventually get a "Flow Rate Error" on the heat pump. At the moment I have the head set to 4m, (the maximum), and this stops the flow rate error message and gives me a DT of 14C.
I have Dp-c, which is what they recommend for UFH?
No sign of Dynamic Adapt in the instructions or on the display!
