- heating domestic water.
Weather compensated controller WDC10B
Weather compensated controllers WDC10B are designed to regulate space heating and domestic hot water heating in individual houses. They allow the regulation of one or two heating circuits, the switching between heat sources and the protection of the return when the storage tank is filled. They are used for heating systems with one or two boilers, a heat pump, a heat storage tank and a solar system.
