Maximum pump speed setting on remote control
Standard pump speed is automatically controlled to get the designed water temperature different between water
inlet and outlet (ΔT). Instead of setting the standard pump speed, maximum pump speed is manually adjusted by
the installer according to water circuit pressure drop.
However, the following sequences do not follow maximum pump duty setting by remote control.

Pump down mode
