9.5.18 Heat consumer charging

Menu: Expert menu > Settings > C: Prio./sec.prio.
If there is more than one heat consumer in a solar heating 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 priority
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.
