External boiler request (X28)
Potential-free relay output for switching an external boiler, for example, an external boiler
receives a release from the SOLARFOCUS boiler control;
connect to X28 on SOLARFOCUS power element.
Attention! The connection is potential-free and has a maximum load of 5A.
Fault (X29)
Potential-free relay output, for example, to switch a warning device (optical/acoustic) upon
occurrence of an operating fault on the boiler;
connect to X29 on the power element.
Attention! The connection is potential-free and has a maximum load of 5A.
External request (X51)
Input, i.e. the SOLARFOCUS boiler can be started by an external control;
connect to X51 on the power element.
Attention! This connection must be potential-free.
Connect the heating circuit pump (X9, X10)
Connect heating circuit pump 1 to power element connector X9 and heating circuit pump 2
to X10 .
If required (e.g. in the case of underfloor heating), connect a limiting thermostat.
If a limiting thermostat is not used, the contact must be bridged.
7.7 Internet connection
To connect the boiler control with the Internet, connect the Ethernet port X2 (type RJ45) on the back of the dis-
