Irradiation sensor offset
If an irradiation sensor is to be connected, an offset has to be carried out before
the connection is made.
To carry out the offset, proceed as follows:
Î
Adjust the irradiation sensor type in the Type channel.
Î Select the Offset channel.
Î Confirm the reset enquiry with Yes.
Î Select back to return to the Inputs menu, then connect the irradiation sen-
sor.

13.3 Outputs
In this menu, the control type and the minimum speed can be adjusted for each
individual relay of the controller and the external modules.
The control type determines the way speed control of a connected pump is ef-
fected. 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 (factory setting)
With the control types Adapter, 0-10 V and PWM, the relay itself is not in-
volved in speed control. A seperate connection for the corresponding signal will
have to be made (see figure).
If PWM / 0-10 V is selected, the channels Output and Profile appear. In the
Output channel, one of the 2 PWM outputs can be selected. In the Profile chan-
nel, different PWM curves corresponding with the pump in use can be selected.
Note:
If PWM / 0-10 V is selected for an output, the adjustment range for the
corresponding minimum speed will extend to 20 … 100 %.
Note:
For boiler modulation, the 0-10 V outputs A and B can be allocated to a
demand in the Shared relays menu.
