Malfunction list

Most operational malfunctions are not caused by faulty equipment but rather by improper installation or

disregarding of planning guidelines. Therefore, a complete fault diagnosis always involves a thorough

examination of the entire system (e.g. hose connections, control system, etc.).

Warning

Fault

Message

Possible causes

Remedy

W14

–––

Max Door Open

The cabin door was open too long.

Note: The Condair Delta SPA Control Box or the Nordmann Omega

automatically disconnect all heating systems (steam, bench hea-

ting, sauna heater, etc.) until the cabin door is closed again.

The cabin door was open longer

than the set "Door open" time.

Close the cabin door.

–––

E18

Cabin Temp. Sensor

Instable

Measurement of cabin temperature unstable.

Note: The operation of the Condair Delta SPA Control Box or

Nordmann Omega is stopped. After eliminating the fault, the

Condair Delta SPA Control Box or the Nordmann Omega must be

switched off and on again (depending on which device the fault has

occurred).

Unstable temperature measure-

ment due to manipulation of the

temperature sensor in the cabin.

Check temperature sensor in the

cabin.

–––

E20

Safety loop

External safety loop is open.

Note: The Condair Delta SPA Control Box or the Nordmann

Omega go into standby operation. As soon as the external safety

loop is closed again the Condair Delta SPA Control Box and the

Nordmann Omega continue to work normally.

One or more monitoring

device(s) of the external safety

loop has/have triggered.

Check the monitoring device(s)

of the external safety loop.

External safety loop not connec-

ted correctly.

Let have the wiring of the external

safety loop be checked and cor-

rectly connected by an electrician.

–––

E21

Max. level

Water level in the steam tank of the Nordmann Omega too high.

Note: The operation of the Nordmann Omega is stopped. After the

fault has been eliminated, the Nordmann Omega must be swit-

ched off and on again. If the Nordmann Omega is controlled by a

Condair Delta SPA Control Box, the Condair Delta SPA Control Box

must also be switched off and on again after the Nordmann Omega

has been restarted.

Level unit calcified.

Clean level unit.

Hose connections between level

unit and steam tank blocked.

Check/clean hose connections

between level unit and steam

tank blocked.
