Control panel for electric heating in houses and blocks of flats - controls total consumption and has load-shedding relays operating when power is required by other circuits

摘要

In an installation in which the power allowable for heating is controlled generally in relation to the external conditions, part of the heating load can be shed, and circuit protection elements are centralised. The entire heating system is centrally controlled from a single control panel which includes power limiting devices, protection elements and heating monitoring circuits. When a circuit other than the heating circuits requires current, power to certain heating circuits is automatically cut.
