Parameter to set if Pump Speed control (237) is setted on modulating
ΔT ( ow - return) for circulation pump modulation
This parameter can be used to set the di erence between the ow and return temperatures, which determines the commutation
between low and high circulation pump speed. E.g.: param. 14 = 20 if the T ow - Tret > 20°C; the circulation pump will be
activated at maximum speed. If the T ow - Tret < 20 - 2°C; the circulation pump will be activated at minimum speed.
The minimum wait time between speed changes is 5 minutes.
