PUM2
Pump control type R2
Selection: OnOF, PULS, PSOL, PHEA
Factory setting: OnOF
With this parameter, the pump 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-efficiency pump (HE pump)
• PSOL (PWM profile for a HE solar pump)
• PHEA (PWM profile for a HE heating pump)
Minimum speed
n2MN
Minimum speed R2
Adjustment range: (10) 30 … 100
Factory setting: 30
A relative minimum pump speed can be allocated to the output R2 via the adjust-
ment channel n2MN.
Note
The pump speed must be set to 100 % when auxiliary relays or valves are
connected.
Maximum speed
n2MX
Maximum speed R2
Adjustment range: (10) 30 … 100 %
Factory setting: 100 %
In the adjustment channel n2MX a relative minimum speed for a pump connected
can be allocated to the output R2.
Note
The pump speed must be set to 100 % when auxiliary relays or valves are
connected.
