Where possible, avoid installing a secondary circulation
line, since a secondary circulation line results in higher
energy consumption. If the installation of a secondary
circulation line is required, keep circulation operations to
a minimum by only using circulation mode when
required for demand and temperature reasons.
>
Connect the
secondary
circulation line (

) to the hot
water pipe (
4
) via a hot water thermostat mixer (
2
).
6.5.3 Setting the hot water thermostat mixer
a
Danger!
Risk of burns and scalds!
Water at a temperature of more than 60 ºC
can escape from the water draw-off point.
>
Set the hot water thermostat mixer to
less than 60 ºC and check the tempera-
ture at a hot water draw-off point.
>
When commissioning the solar heating system for the
first time, set the hot water thermostat mixer to the
required maximum temperature.
This maximum temperature is observed at the hot water
draw-off points.
