Error Messages Basic Display / Error Stack - Rotex Controller Series Product Documentation

EbV
If a boiler control is connected, helpful error messages may come from the boiler control which will be
displayed as follows:
Malfunction log: The control unit has a malfunction log in which a maximum of five malfunction
messages can be saved. The malfunction messages are displayed with date, time
and malfunction type (error number). The query is carried out in the sequence of the
entered malfunction messages in the level ALARM.
The last (= most recent) malfunction message is in first position (No. 01); the
previous malfunction messages are shifted down by a position upon each new
malfunction message. The fifth malfunction message is deleted when a new
message appears.
Operation:
Notes: The outdoor sensor input can be used to shut down the heating system in plants with
MCBA boiler controls. A sensor short circuit of the outdoor sensor suppresses the
error message and shuts down the plant. Instead of the error message, the message
Heat.system appears.
If there is a defect in the heat generator (error message 30-1 or 31-3) and the plant
frost protection is active, the boiler corrosion protection is switched off and thus the
heating circuit pumps are activated to lower the risk of the plant freezing.
