CONNECTION TO POWER SUPPLY
High-efciency pump:
A high-efciency pump can be connected via RO1 or RO2.
The appropriate control signal is issued at TS4.
Thus, TS4 is no longer available as input.
The control signal may be an analog voltage 0 - 10V or a PWM signal.
For further details, please refer to the pump specication.
For denition and settings, the professional mode under 1.3.7 has been provided.
RO1 or RO2:
230V supply of the
high-efciency pump
TS4: PWM-control signal
for the high-efciency
pump
Left-hand terminal: GND
Right-hand termin.: Signal
Volumetric ow sensor:
Measurement of solar radiation (heat quantity):
The solar yield is calculated from the ow rate and the differential temperature.
The differential temperature is the difference in the temperature of the collector
sensor and the solar circuit return line sensor.
An impeller sensor can be connected to TS3 or TS4 and must be adjusted during
installation. The temperature sensor for the solar return line must be set
in the menu ›1.1.4 Heat quantities‹. Solar radiation measurement using an
impeller sensor is possible for plant layouts 1, 2, 3, 4, 5, 7, 10, 12 and 14.
