Note:
The adjustment routine above only describes the first, indicative part of the system's
adjustment The following must also be taken into account:
•
•
•
Compare the ΔPa value on
the manometer with the P3 - > P4 value,
noted as described on page 149.
Press and hold the alarm reset (E) and
adjust the exhaust air up (D) or down (B)
until the measured ΔPa value approaches
as closely as possible the P3 - > P4 value
noted on the label.
Strong wind buffeting the building may
affect the adjustment of the unit.
Connect the ΔPa meter (manometer) across the exhaust air direction P1 - > P2
one more time. Check the measured ΔPa value as it may have changed due to the
adjustment on the exhaust side. Make an adjustment if necessary.
Check the airflow in all rooms and adjust the airflow rate by opening/closing the
valves in the different rooms.
Reconnect the ΔPa meter (manometer)
to check the measured ΔPa value on both
the supply and exhaustsides.
Note the measured values on the label.
Press and hold the fan button (B) and
weekly program button (D) for five sec-
onds until the LED stops flashing.
The unit is now calibrated.
adjust the valves in all rooms until the required airflow for each room has been achieved.
check the main airflows according to the instructions earlier in this procedure, as major
valve adjustment may greatly affect the main airflow.
during regulation, it must be ensured that the extract airflow is always at least 5% higher
than the supply airflow in order to create conditions for mass balance in the system.
