If there is more than one heat consumer in a solar thermal system, a cylinder priority order must be
defined. That definition determines the priority for charging the heat consumers. A distinction is
made between high and low priority heat consumers.
When the high priority heat consumer reaches its cut-in temperature differential, it is charged until
it reaches its maximum temperature. If it reaches its cut-in temperature differential while the low pri-
ority heat consumer is being charged, charging of the low priority heat consumer is interrupted until
the high priority heat consumer has been charged to its maximum temperature.
If only one of the cylinders is selected as a heat consumer, only the selected cylinder is charged.
