Expert/Relay/Signal1 (...3)
Selection: Off, PWM, 0-10V
Factory setting: PWM
If Signal = PWM or 0-10V, the following channels ap-
pear for the corresponding output:
Exper/Relay/Profile1 (...3)
Selection: Solar / Heating
Factory setting: Solar
Expert/Relay/Max speed1 (...3)
Adjustment range: 30 ... 100%
Factory setting: 100 %
Adjust the CS-type in this menu. The CS-type should be
matched to the code letter printed on the CS type label.
The CS-offset adjustment should be carried out with
the irradiation sensor disconnected.
Furthermore, an offset for sensors 1 ... 10 can be car-
ried out.
Relays 1 to 3 are semiconductor relays for pump speed
control of standard pumps. Relative pump speed is
adapted in 10 % steps to the current temperature dif-
ference between the collector and the store (see also
4.1 speed control).
In some cases, it is necessary to adapt the factory
setting of the minimum pump speed (30%). If it is set
to 100 %, pump speed control is deactivated (valves).
With the Signal channels, the speed control signal types
can be adjusted for the corresponding relays.
If PWM or 0-10 V is adjusted for an output, 2 additional
adjustment channels appear.
In the „Profile" channel, different PWM characteristic
curves are available and have to be selected according
to the pump type in use (see fig. page 112).
In the „Max speed" channel, a maximum pump speed
can be adjusted for the corresponding output.
