4.2 Frost safety
To prevent freezing of the heat exchanger at very low outdoor
temperatures, the Elan appliance is equipped with frost protec-
tion. The water temperature sensor measures the temperatu-
res at the heat exchanger.
When the temperature drops below limit value 1 set at step
no. 10, output H is deactivated and output G is energised (see
IRUDQH[SODQDWLRQRIRXWSXWV*DQG+
The system fan does keep running to ensure that the system
remains ventilating.
If the temperature drops below the limit value 2 set at step no.
11, the system fan is switched off as well.
When the temperature at the heat exchanger rises again, the
Elan control is automatically reactivated.

turn duct. In this version the appliance may take in between 0
and 100% outdoor air, dependent on the setting of the diverter
valve.
To make the appliance perform as an outdoor appliance, the
installer must change parameter 9 in the settings menu of
the control unit, using the control panel on the appliance (see
