With the ET adapter power reduction, the setpoints of the Hall gag can be lowered by one third for energy optimization or power reduction on the ET thermostat. The control signals (5VDC) are connected via the 4-pin OPT interface either to DIN 18875 to an energy optimization system or to an additional switching contact (bridge) for manual operation.
As long as the signals b and c are connected to each other at the 4-pin OPT interface, the set point does not reduce.
