An
“external temperature sensor”
should
be installed into the supply line, about 50
cm after the aux. heater battery. In case
of low-temperature heating, the Hygro-
Box can also be integrated directly into
the heating system without mixer and
external sensors. The supply air tempe-
rature is then not actively regulated.
