Level 5
In the adjustment channel n1(2, 3)LO, a relative minimum
speed for connected pumps can be allocated to the outputs
R1, R2 and R3.
Minimum speed
PUMP1 (2, 3) / n1 (2, 3 LO
Speed control
Adjustment range: 20 ... 100 %
in steps of 5%
Factory setting: 30 %
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 (pulse packet control via semiconductor relay)
Adjustment for high effi ciency pump (HE pump)
• PWM A (Wilo)
• PWM b (Grundfos)
• PWM C (Laing)
Pump control
PUMP / PUMP1 (2, 3,)
Pump control
Selection: OnOF, Puls, PWM A,
PWM b, PWM C,
Factory setting: PULS
Sensor maximum store temperature
Allocation of the sensor for store maximum limitation. The
maximum limitation always refers to the sensor selected.
If S3 is selected, the differential control will be carried out
using S1 and S2. The temperature at S2 can exceed the
adjusted limit temperature, the system will not switch off.
If the value at S3 reaches the limit temperature, the system
will be switched off.
LOAD(1,2) / S(1,2)MAXS
Sensor store maximum temp.
Adjustment range:
1-store system: S2, S3
2-store system: S4, S5
Factory setting:
1-store system: S2
2-store system: S4
Note:
In 1-store systems with sensor S3 as the re-
ference sensor, loading will be switched off if
the temperature at S2 or S3 reaches the store
emergency shutdown temperature.
In 2-store systems, loading will be switched off
if the temperature at S4 or S5 reaches the store
emergency shutdown temperature.
Loading store 2
In a 2-store system, the second store can be switched off
for loading via the parameter
LST2
.
If
LST2
is adjusted to
OFF
, the system runs like a 1-store
system. The representation in the display does not change.
LOAD2 / LST2
Loading store 2
Selection: ON / OFF
Factory setting: ON
Note:
For more information about connecting HE
pumps, see page 68.
Note:
When loads which are not speed-controlled (e. g.
valves) are used, the value of the corresponding
relay (n1, n2, n3) must be set to 100% or the
pump control type must be set to OnOF in
order to deactivate pump speed control.
Note:
PUMP3 can only be set to OnOf or PULS.
Note:
When loads which are not speed-controlled (e. g.
valves) are used, the value of the corresponding
relay (n1, n2, n3) must be set to 100% or the
pump control type must be set to OnOF in
order to deactivate pump speed control.
Maximum speed
PUMP1 (2, 3) / n1 (2, 3) HI
Speed control
Adjustment range: 20 ... 100 %
in steps of 5%
Factory setting: 100 %
In the adjustment channel n1(2, 3)HI, a relative maximum
speed for connected pumps can be allocated to the outputs
R1, R2 and R3.
