The table below presents an overview of the alarms that may occur (the alarm numbers are displayed in the alarm

menu).

Alarm

Error type

Solution

A00

No error

A01

XTP flow alarm.

Defaults (menu 23):

Chimney fan: < 64% of set pressure

Air supply fan: > 300% of set pressure

Check:

The flue, the chimney and the chimney fan for blockages.

The commissioning.

That the measuring probe and the spigots on the pressure

transducer are not blocked.

A02

PDS check error

Check:

The setting of the monitoring unit (the PDS).

The connection to the PDS.

The PDS’s switch function.

A03

PDS error (flow error)

Check that:

The PDS is connected.

The PDS is correctly adjusted in relation to the set point.

Menu 31 has been set correctly (1).

A04

XTP Start Timer error (flow error)

Check:

the hose to the pressure transducer.

the commisioning.

the chimney fan is of sufficient capacity.

A10

XTP not connected

A11

PDS not connected

Check the PDS connection.

A13

AUX alarm (alarm for terminals 26–28)

Check:

the connections to terminals 26–28.

the setting in menu 31 (2)

the loop between terminals 26 and 28.

If XTP is connected : power off/on the unit.

If error persist contact dealer (defective unit).

A14

Temperature sensor not connected

A16

24 VDC overloaded

Check:

the load on terminals 19-20.

If error persists, contact dealer (defective unit).

A17

XTP connected (error only for the 2-stage
speed regulation function

)

Remove the XTP. The XTP must not be fitted in speed-

regulation mode.

A18
