Connection to power supply
High-efficiency pump:
A high-efficiency pump can be connected via RO1 to RO4.
The appropriate control signal is issued at TS7 to TS10.
Thus, TS7 to TS10 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 specification.
For definition and settings, the professional mode under 1.2.9 has been provided.
RO1 to RO4:
230V supply of the
high-efficiency pump
TS7-TS10: PWM-control signal
for the high-efficiency pump
Left-hand terminal GND
Right-hand termin.: Signal
Volumetric flow sensor:
Measurement of solar radiation (heat quantity):
The solar yield is calculated from the flow 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. There are various technical options:
a) Use of a vortex volumetric flow sensor with 2 analog signals for flow rate and
temperature. The vortex sensor can be inserted directly at the plug connector provided
behind the TS terminals. All plant layouts (systems) permit solar radiation.
Pin assignment
b) Impeller sensor (incrementation input)
An impeller sensor can be connected to TS6 to TS8 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 yield measurement with impeller sensors is possible for all systems.
