Circulating pump
Important
The benchmark for the most efficient circulating pumps is EEI ≤
0.20.
The circulating pump in the indoor module is a variable speed pump. It
adapts its speed to the distribution network.
The speed of the circulating pump is controlled to reach a set point flow
rate. This set point depends on the HP069 parameter. This value is auto
matically configured according to the power of the outdoor unit when the
codes CN1 and CN2 are configured when the device is first started.
1 Available pressure in metres of water column (mWc)
2 Water flow rate in cubic metres per hour (m

/h)
3 Available pressure for 4.5 to 8 kW outdoor units
4 Available pressure for the 11 and 16 kW outdoor units
