8.2 Modulating pump for CH demand
The control supports PWM modulation for the general pump.
The boiler pump is modulated when there is a demand for CH.
During any other demand, the PWM pump will run at a fixed speed set by the Default Duty cycle parameter. How
the pump is modulated is controlled with the Modulating_Pump_Mode setting.
