Climate curve
You can choose different climate correlation curves or your own customised curve. Once the curve is selected, the unit sets the outlet water temperature automatically according to the outdoor ambient air temperature.

Floor preheating and drying
Protect your home floor by activating the Floor Preheating function which slowly increases the heating temperature of the floor coils, avoiding possible floor damaging and transitioning smoothly to the heating function. The Floor Drying Up function provides an additional solution to the installer as it helps remove any residual moisture from newly installed floor coils, further protecting the installation and ensuring the optimal and effective operation of the heat pump.
