To set the output ratio between the supply and extract air fans:
IMPORTANT
Adjust the air flows according to the values specified in the
ventilation plan. It is recommended that the air flows be adjusted
without having to choke the air flows at the valves. This is the most
energy-efficient set up.
First, set both values as close to the ideal value as possible by
looking at the supply and extract air fan curves. If the ratio between
the air flows is very high at first, the ventilation unit may have to
carry out extra defrosting cycles in sub-zero temperatures, thus
making adjustment of the air flows more complicated. Check
the air flows by measuring them at the valves, and fine-tune the
percentage values as required.
NOTE
If the outdoor air is extremely cold (below -10°C on an aluminium
cell, the ventilation unit may have to defrost the heat recovery cell.
If this happens, the Defrosting icon will be displayed on the control
panel. The air flows cannot be adjusted during defrosting.
SUPPLY AIR
When you want to make the system supply air settings, proceed as
follows:
1. The deployment wizard Fan settings screen is opened.
2. Set the supply air quantity as a percentage of the maximum by
using the Plus and Minus buttons. The fan speed (1/min) will
change, according to the percentage value.
3. Once you have set the supply air fan settings, press the Right
arrow button.
EXTRACT AIR
When you want to make the system extract air settings, proceed as
follows:
1. The deployment wizard Fan settings screen is opened.
2. Set the extract air quantity as a percentage of the maximum by
using the Plus and Minus buttons. The fan speed (1/min) will
change, according to the percentage value.
3. Press the OK button.
4. The extract air fan ratio is now set.
NOTE
You can browse the Fan settings by using the Right arrow button.
WARNING
The ventilation specialist has made
the supply and exhaust air settings
when deploying the ventilation
unit. If you make changes to
the settings, ensure that they
conform with the ventilation plan.
