NOTICE

A detected error is indicated on the display by means of blocking or error messages. A
distinction should be made between these two messages due to the fact that blocking
can be of a temporary nature, however, error messages are fixed lockings. The control
will try its utmost to prevent locking and will temporarily switch off the unit by blocking
it. The following is a list of some messages.
External safety contact cut off
Outdoor sensor not connected
Incorrect parameter setting of the minimum or maximum power.
A T has been detected between flow and return sensor whereas the burner is not in operation.
After the T has disappeared the block will clear.
