Feed line/return line 55/45 °C
Feed line temperature of at least
+30 °C!
In case of low temperature
heating, an additional auxiliary heater
battery must be installed at the air outlet
downstream of the air humidification
unit, in ordert o grant a comfortable
supply temperature (see figure). A feed
line temperature below 36 °C and a very
cold temperature, or an outlet tempera-
ture below 19 °C at the internal sensor
decreases the humidification, as too
little evaporation energy is available.
17.6 LOW TEMPERATURE HEATING
The auxiliary heater battery
may be mounted only in this
position*
, thus guaranteeing
simple accessibility for a possible UVC
pipe exchange.
