R1 of the SC controllers comprises a semiconductor relay (TRIAC), also suitable for RPM
control with a maximum switching current displayed on the unit type plate. Both the SC100
and the SC200 contain an electromechanical relay, R2.
Note that the SC300 contains two RPM relays, R1 and R2 as well as an electromechanical
relay, R3. The SC200 and SC300 are therefore suitable for controlling two pumps i.e. for an
east/west panel array or a stagnation configuration requiring a second pump.
Caution
Avoiding damage and malfunctions – When connecting an external relay or contactor, or
when connecting a pump which has its own electronic RPM control, the controller output’s
RPM control must be deactivated (see “Setting the RPM control parameters” in the
Controller Manual).
R2 on the SC100 contains a switched output via an electromechanical relay with a
maximum switching current displayed on the unit type plate. Note the wire bridge (D1) must
be connected.
Connection of first output/pump (R1)
Connection of second output (R2) if required
