Output mode, output limits
Depending on the pump version, the control mode of the pump can be normal (0 – 100
“solar mode“) or inverse (100 – 0, “heating mode“). There can also be specific requirements
for the limits of the control range. These can be found in the information of the pump manu-
facturer.
The following parameters define the control mode and the lower and upper limits of the
output analogue value:
0-100
Output mode setting: 0-100 corresponds to 0->10V or 0->100% PWM,
100-0 corresponds to 10->0V or 100->0% PWM (inverse). (fs = 0-100)
MIN
Lower speed limit (fs = 0)
MAX
Upper speed limit (fs = 100)
Control commands
Using the following commands a system test (see pump standstill) or monitoring of the
actual speed (see stability problems) is possible:
ACT 19
Currently the pump is running (actual value) at speed stage
19
.
TST 19
Currently the speed stage
19
is issued on a
t
e
st
basis. Invoking TST automatical-
ly results in manual mode. As soon as the value above the key
(= Entry) blinks
the pump is controlled at the speed stage displayed.
Setting range: 0 to 100 with keys
