CONNECTION OF EXTERNAL HEAT SOURCE
For connection of an external energy source directly to
the internal volume in VVM 310, suitable when the en-
ergy source has a small volume, such as a boiler without
an accumulator tank or an electric heater. This docking
uses the energy source for both heating and hot water.
For connection, the DEH 310 accessory is required, see
"Accessories" on page 69. With such docking, the
"prioritised additional heat" function can be used.
