In
case of low temperature heating, an ad-
ditional auxiliary heater battery must be
installed at the air outlet downstream of
the air humidification unit (see figure). In
case of supply line temperatures below
36 °C, and very cold outdoor temperatu-
res, or an outlet temperature below 19
°C at the internal sensor, the humidi-
fication output will reduce as too little
evaporation energy is available.

Attention:
The aux. heater battery must
only be mounted in this position*, so that
easy access for the potential repla-
cement of a UVC pipe is ensured for
maintenance purposes.
