Atmos Multi Mk2, Manual

6. SERVICE SERIAL NUMBER 

 
Every malfunction is preceded by a service identification number. The service identification number is a handy tool for 
servicing the

 ATMOS MULTI. 

 By changing this number after every service, the next time, one can see which blocks 

and/or malfunctions occurred since the last service. 
 
To change the service identification number, the malfunction logbook 

F

 must first be selected. Then the ‘Hot water’ 

button is kept pressed in while finally the ‘Set’ button is pressed. 
 
The service identification number will be increased by 1 to a maximum of 6, and will then start again from the number 
0. When changing the service identification number, it is simultaneously changed in the blocking logbook. 
 
The example below shows the logbook codes in the CH Water display, obtained by stepping through the most recent 
logged faults using the ‘Hot water’ button.

*** Malfunction 

13 was added last year. This can be seen by the first number 1 (service identification number). The 

second number 3. is the malfunction (in this case no ionisation signal during start-up procedure). The two last 
malfunctions are preceded by a different service number and are therefore from the previous services. 

 
COMMENT! 
Do not forget to increase the service identification number after each service/maintenance and record this with the date 
on the service chart of the appliance.
