Pump control type
With this parameter, the relay control type can be adjusted. The following types
can be selected:
Adjustment for standard pump without speed control
• OnOF : Pump on / pump off
Adjustment for standard pump with speed control
• PULS : Burst control via semiconductor relay
Adjustment for high-efciency pump (HE pump)
• PWM A (Wilo) (for R1 and R2 only)
• PWM b (Grundfos) (for R1 and R2 only)
• PWM C (Laing) (for R1 and R2 only)
Note:
For more information about connecting HE pumps, see page 35.
Relay allocation for PWM outputs
PWM1 is allocated to R1, PWM2 is allocated to R2.
Minimum speed
In the adjustment channel n1Lo (2,3), a relative minimum speed for a connected
pump can be allocated to the outputs R1, R2 and R3.
Note:
When loads which are not speed-controlled (e. g. valves) are used, the
pump speed value of the corresponding relay must be set to 100 % or the
control type must be set to OnOF in order to deactivate pump speed
control.
Maximum speed
In the adjustment channel n1HI (2,3), a relative maximum speed for a connected
pump can be allocated to the outputs R1, R2 and R3.
Note:
When loads which are not speed-controlled (e. g. valves) are used, the
pump speed value of the corresponding relay must be set to 100 % or the
control type must be set to OnOF in order to deactivate pump speed
control.
