This is a shortened list of the error codes, which will be displayed on the Programmer or on the room unit. If more than one error is active, the one with the higher priority or the one that appeared first will be displayed.
Error codes 157,274,261,262 and 300 can be reset by the user by pressing the user reset button for 2 seconds, turning the dial to alter the flashing NO to a YES and then pressing the OK button. After a few seconds the error should clear enabling a restart of the appliance. Errors 261 and 262 may indicate a problem with the gas supply.
Errors 157,164,274 and 300 may indicate a problem with the central heating water fill or pump. If the problem persists contact the installer with the error code.
Error 158 indicates a possible blockage in the condense drain.
Error codes 10 through to 99 (except 97) are linked to installation and commissioning of your system and as such you should contact your installer to complete commissioning.
Error codes that are shown as automatic reset will disappear once the fault has cleared. The appliance will restart if there is a demand except in the case of errors 263 and 264 when the appliance must be switched off and on again to enable a restart.
All other error codes indicate a fault condition, which will require the attention of a service engineer.
