Problems
The air replacement is too
low or the distribution poor,
which causes low air re-
placement in critical rooms.
The unit is set to Manual
Mode at one fixed speed.
The display goes into Sleep
Mode after 2 minutes to
save power.
Cause
Adjust the air flow and dis-
tribution from the ceiling
valves to ensure air re-
placement in critical areas.
Set the unit to Automatic
Mode to keep dampness at
an appropriate level auto-
matically.
Do not let the unit operate
constantly at Fan Step 1 or
2 in Manual Mode as it will
not guarantee keeping the
humidity levels down when
the moisture load in the
house is high.
Set the unit to Automatic
On-Demand Mode, after
which the unit will adapt
the air flow to requirements
in the house.
The unit is functioning cor-
rectly.
