Second DHW temperature sensor, bottom

The DHW cylinder can be used more
efficiently if the DHW cylinder that is
used allows a second temperature
sensor to be installed further down.
This temperature sensor is used as a
reference point if once only DHW
heating is provided using the "max
DHW volume" (see page 65) demand.
