High-efficiency pump
A high-efficiency pump can be connected to RO1 or RO2. The control signal for the pump is transmitted to TS7 / TS8 /
(TS4). TS4 is therefore no longer available as an input. The control signal can be an analog voltage 0 - 10V or a PWM signal.
TS7/TS8/(TS4):
PWM control signal
for the high-efficiency pump
Left-hand terminal: GND
Right-hand terminal: Signal
