Grundfos UPM3S Series User Manual

Selection of control mode
The selection of the control mode depends on the system
type and the allocation of pressure losses defined by the
valve or consumer authority.
System type Recommended control mode
Heating system with PWM control of the pump.
PWM A profile
Solar system with PWM control of the pump.
PWM C profile
System without PWM control of the pump (stand-alone). Internally controlled
Variable-flow system with relatively
high pressure losses inside heating
appliance and pipes (> 50 % of pump
head).

thermostatic radiator valve
with low valve authority.
