3.2. Product functions

The S2-18 / S2-18S / S2-30 power boosters are used to increase the maximum
switching load of your sauna control unit. The two built-in contactors are used for
switching the mains voltage to the heating system. Contactor K1 (ST1) is used
as a contactor for the safety circuit, and contactor K2 (ST2) as a contactor for
the switching circuit.
When connecting ST2 to one of the heater outputs (U, V or W), the phase align-
ment of the sauna control unit must be disabled.
When phase alignment is activated, this may result in erroneous control
operations and extended heating times.
