5.5.5 “Domestic hot water” mode without storage tank
When “Domestic hot water” is selected, the boiler only produces heat if the DHW tank actually requests
heat within the specified DHW tank loading time.
Example 1: “Domestic hot water” mode without storage tank
DHW tank loading time 1
DHW tank loading time 2
Tip: In systems with solar panels, choose the DHW tank loading time so that solar energy can be used.
