6. ERRORS TABLE
There are 3 types of errors that the electronics can detect; if an error is detected one of the
codes below will be displayed on the screen until it is resolved.
ERROR CODE DESCRIPTION
ERROR1 Failure in microcontroller or RTC (problems with the current time)
ERROR2 Failure of the NTC probe (e.g., disconnected, short-circuited, etc.)
ERROR3 Failure of the EPROM memory
When recovering from an error, the emitter will always return to Standby mode and will not re-
tain any previous mode or state. If the emitter goes to Standby without any specific reason, it
may have recovered from an error.
7. MAINTENANCE AND CARE
The SIENA emitters require very little maintenance.
The surfaces of the emitter must not be cleaned with an abrasive product or those containing
granular substances. We recommend regular cleaning with PH neutral products.
In order to clean the emitter, it is recommended that the electric power is switched off.
Failure to keep the emitters clean may result in dust becoming burnt and depositing on the wall
above the emitter in the form of dark streaks or patches. This type of marking is expressly due
to failure to keep the emitter and surrounding area clean.
