MEASURES

Message on the user interface:

Extract fan stopped

The extract air fan has stopped.

Make sure that the fan is not running. The fan cabling

and operation must be checked, and if necessary the

fan must be replaced. Contact the service centre.

Message on the user interface:

Supply fan stopped

The supply air fan has stopped.

Make sure that the fan is not running. The fan cabling

and operation must be checked, and if necessary the

fan must be replaced. Contact the service centre.

Message on the user interface:

Cell has frozen

The heat recovery cell has

become excessively cold.

Conduct a manual defrost through the control panel

(Service menu > Cell defrost). Try to discover why the

heat recovery cell is frozen.

Message on the user interface:

Temperature sensor 1/2/3/4/5

The temperature sensor indicated

on the user interface is damaged.

The sensor installation must be checked, and if

required the sensor must be replaced. Contact the

service centre.

Message on the user interface:

External sensor

The external temperature sensor is

damaged.

The sensor installation must be checked, and if

required the sensor must be replaced. Contact the

service centre.

Message on the user interface:

service centre.

Message on the user interface:

Bus fault

Problems with the data transfer

bus.

Make sure that the Modbus bus is connected correctly,

and that the devices connected to it are properly

functioning.

The ventilation unit is not

working; the control panel is

not working.

Power input to the unit is lost

Check:

• Fuse in the fusebox

• Fuse in the unit

The ventilation unit is working,

but the control panel is not

working.

Either the control panel 24 VDC

power is lost, or the control panel

is damaged.

Check the cables from the unit to the control panel.

Contact the service centre if necessary.

NOTE

Some condensing water may

have accumulated in the bottom

pool of the unit; this is normal

and requires no corrective action.

WARNING

Water must at all times be kept out

of the electrical system.

TROUBLESHOOTING

CONDENSING WATER

MAINTENANCE OF THE CONDENSING WATER

OUTLETS

In the heating season, the extract air humidity condenses to water.

In new buildings, condensation runoff can form rapidly. Condensed

water must be able to freely leave the unit. At some time before

the heating season begins (e.g. during autumn maintenance),

check that the condensing water outlets in the bottom pool are

not clogged and that there are no leakages. To check this, pour

some water into the pool. Clean as required. Check where the

condensing water outlets are in the Installation section.

NOTE

Error messages are displayed on

the control panel and in the Adroit

Home and Adroit Cloud services.
