HOW TO USE YOUR CARAVAN’S EQUIPMENT
Display. Select panel brightness: Low, Medium or High. You
can also choose whether the status screen should be Normal,
Inverted or Dark. If Dark is selected, the panel will go dark
after 30 seconds and will light up again if touched.

Language. Change the language in the Control Panel menus;
available languages are: English, German and French.
Service. Displays values from the heating system; these are
updated continuously and describe the current status of the
boiler. See Service Menu & Reset.
System configuration, enable installed accessories and
features. Here, you will find all accessories or functions that
can be connected to the Alde Heating System; tick the
features that are installed in the heating system to enable their
use.
Reset. Resets the panel to factory setting. The accessories/
features selected under System Configuration are not
affected.
Glycol fluid
The system must be filled with a fluid mixture consisting of distilled water and glycol. We
recommend using a high quality premixed glycol (with inhibitors) intended for aluminium heating
systems. When using concentrated glycol, the mixture must consist of 60% distilled water, or water
with no salt content and 40% glycol. The use of tap water may cause corrosion and affect the
warranty.
If the system is exposed to temperatures lower than -25ºC, glycol content must be increased, but
must not exceed 50%.
Note: If the glycol fluid is not replaced at appropriate intervals, there is a risk of frost damage,
corrosion, bacterial growth and/or overheating.
The glycol mixture must be changed every two years, as properties such as corrosion protection
degrade. If Alde Premium Antifreeze is used, the replacement period can be extended to max. 5
years of normal use.
Refill the heating system with glycol liquid
Glycol content should be checked at the expansion vessel
using a glycol tester before refill, to ensure that the
concentration of glycol in the liquid is not too high. If the liquid
level has dropped for reasons other than evaporation, check all
joints, rubber hoses, drain taps and air screws for leakage
before filling.
The glycol system is manually replenished in the expansion
vessel. When manually filling, slowly pour the glycol mixture
into the expansion vessel. The level must be approx. 1cm
above the MIN. line (Fig. 11) when the system is cold.
If there are 2 zones, both zones must be vented in the system
after filling. Top up if the glycol level drops after venting. Vent a
newly-filled heating system regularly.
