In this menu, the signal type and the minimum speed
can be adjusted for each individual relay of the con-
troller and the external modules.
Î
In order to make adjustments for a relay, select
the corresponding menu item by pressing button

.
For each relay, the signal type and the minimum pump
speed can be adjusted.
The signal type determines the way speed control of
a connected pump is effected. The following modes
are available:
Adapter = speed control signal via a S-Bus / PWM
interface adapter
0-10 V
= speed control via a 0-10 V signal
PWM =
speed control via a PWM signal
Standard = burst control
Note:
Speed-controlled high-effi ciency pumps re-
quire two separate connections (pump con-
nection cable for power supply, signal cable
for transmitting the PWM / 0-10 V signal)
