APPENDIX 2. Fault Finding
1. GENERAL
The Atmos Multi has 3 types of error messages:-
1. Warning messages
In this case, instead of the status message, a letter appears on the diagnostic display for one second, once every 5
seconds.
2. Blocking messages
A permanently illuminated letter appears on the diagnostic display.
3. Malfunction messages
A flashing letter or number appears on the diagnostic display.
In the event of a warning message, the function to which the message applies will be switched off while the appliance
continues to operate.
In the event of a malfunction message, the entire appliance will be shut down requiring manually resetting before the
boiler will continue operation.
OPERATING CODES ON ATMOS MULTI
See also Table 1 in Section 5 of the Manual. The following appear on the status display:-
1 Hot water heating operating
2 Central heating operating
3 Hot water and central heating – priority to hot water
4 Hot water and central heating - supply to both
The dot in the bottom right hand corner of the diagnostic display indicates the following burner function:-
No dot No burner
Slow flashing dot Minimum fire
Increasingly fast flashing dot Higher & higher firing
Constant dot Burner on maximum output
The dot in the bottom right hand corner of the central heating display: -
Dot Motorised valve energised to send
water to the central heating circuit
ATMOS MULTI Mk2 version 2004 Appendix Page 10

2. SUMMARY OF MESSAGES
This section provides a brief description of the warning, blocking and malfunction messages which appear on the
appliances diagnostic display. The causes of these messages are addressed in more detail in section 3.
2.1 Warning messages
A warning message is identified by a letter that appears on the diagnostic display once every 5 seconds, for a period of
1 second, instead of the status message.
Diagnostic display code
Status
message
(Number)
Warning every 5
seconds Message
b Incorrect hot water tank temperature reading, value<-10oC or> 118oC
c Incorrect central heating water pressure, value between 0 and 0.5 bar or 3 and
4 bar (capacity is limited to low setting)
d Incorrect central heating return sensor reading, value<-10oC or> 118oC
8
h Incorrect outside sensor reading, value<-15oC or>118oC
2.2 Blocking messages
A blocking is an error that occurs without causing a malfunction. The appliance waits until the blocking has been
resolved and then continues to operate normally. A blocking is indicated by a permanently lit letter on the diagnostic
display.
Code
Diagnostic
display Central heating water display Message
H H Central heating water temperature sensor error value >118oC
c L L Central heating water temperature sensor error, value <-10oC
C* Central heating pressure lower than 1 bar (occurs when the plug is inserted
into the power socket)
F Mains frequency error
H Internal error
L Electrical mains plug error-correct supply polarity

* this code will not be stored in the memory
ATMOS MULTI Mk2 version 2004 Appendix Page 11

2.3 Malfunction messages
A malfunction is an error which is so serious that the appliance is locked. A malfunction message is identified by a
locked control unit accompanied by a flashing number or letter on the diagnostic display. The appliance can only be
unlocked by pressing the reset button.

3. CAUSES OF MESSAGES
3.1 Warning messages
A warning message is identified by a letter that appears on the diagnostic display every five seconds for a period of one
second instead of the status message. The appliance continues to operate, but the function to which the message applies
will be switched off of ignored. Once the cause of the warning message has been solved, the appliance will start up
again automatically so resetting is not necessary. The possible causes are described below in order of probability. Also
look for the malfunction in this order.

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 Fmust 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.

* Two times 07. means insufficient central heating water flow during central heating operation.
** One 0c means for example that the central heating water temperature connector was loose.
*** 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.

APPENDIX 3. Appliance Guarantee
GUARANTEE

What is covered by the Guarantee?
Atmos guarantees the heat exchanger and the water
heater tank for material and construction faults for five
years and the other parts for two years. Both periods
are calculated from the date of commissioning.
This guarantee implies that the purchaser of this
appliance is entitled to free delivery of the replacement
part. Your installer may charge for the costs of
dismantling and replacing the defective part.
Repairing or replacing parts during the guarantee
period does not extend the length of the guarantee.
Atmos gives a 1 year guarantee on replacement parts.
Parts or appliances sent to the factory for repair or
replacement must always be sent postage paid.
Defects caused by corrosion - both internally and
externally - of any nature whatsoever, whatever their
cause, and defects resulting from scale deposits are not
covered by the guarantee.
Secondary damage, including water damage resulting
from the appliance leaking, loss of earnings resulting
from the failure of the appliance to perform correctly,
fire, legal liability of the user to third parties and so on,
do not come under the guarantee. The right to assess
guarantee claims is reserved to Atmos, who must
always be given the opportunity of inspecting the
appliance on site.

Who conducts the Guarantee?
The provision of service and the execution of this
guarantee is the responsibility of the installer from
whom you bought the appliance.
Guarantee stipulations
Claims can only be made on the guarantee if the
enclosed GUARANTEE REGISTRATION CARD has
been completed and signed and returned to Atmos
within 14 days of the installation date.
The appliance should be installed by a recognised
installer according to the Atmos Multi installation
instructions and the general and local regulations
applicable at the time of installation.
The user must operate the appliance in accordance with
the OPERATING INSTRUCTIONS. The guarantee
becomes null and void if the appliance is used
incorrectly, or in the event of proven negligence, or
incorrectly implemented repairs. The guarantee also
becomes null and void if changes are made to the
appliance without our knowledge. The same applies if
the data plate on the appliance is removed, crossed out
or made illegible.
Repairs should be carried out by a recognised installer.
Exclusively Atmos parts must be used.
The annual inspection and maintenance must be carried
out by a recognised installer in accordance with the
maintenance advice provided by Atmos.
If a defect occurs, the appliance will be assessed as it
was originally set up and connected.
Receipt, Guarantee Registration card and Proof
of Guarantee
Claims can only be made on the guarantee described
above upon submission of the receipt invoice together
with the fully completed proof of guarantee. You must
retain this PROOF OF GUARANTEE, which you will
find at the back of the USER OPERATING
INSTRUCTIONS. The appliance serial number is also
stated on this document. The purchase date and the
name of your supplier must be clearly stated on your
receipt.
