Electronic switchgear used only together with the boiler control contactor ABB ESB25-30N-06 230 V AC DC for switching boiler systems.
Functionality
In normal operation, the low tariff control (night connection) is switched through from the ripple control receiver (RSE) closing contact to the ABB ESB25-30N-06 control contactor.
The day switch-on allows the boiler control to be switched on independently of the low tariff control. It is activated with a short keystroke (boiler tag ON, LED illuminated). With another button press, the tag boiler heating can be switched off again.
The activated day switch-on is automatically reset at the next control signal from the ripple control receiver (night connection) and the boiler is again heated only during the low tariff period.
The red lever switch is in the ON position during normal operation. In OFF position, the boiler is completely switched off, for example, during vacations.
The LED lights up red when the day switch-on is activated and green when the night switch-on is activated.
