19
Incorrect settings values in external RAM
This fault will be detected if the information in the battery-backed memory has
become corrupted.
1. The fault will correct itself, but the data stored in the current memory position
will be lost.
20
Memory allocation error
The microprocessor is unable to reserve sufficient memory space.
This fault will generate fault code 26.
1. Send for a service technician
22
Transmitter buffer overflow
The control panel is unable to transmit information to the other units at a
sufficiently high speed.
1. Turn off the mains power supply to reset the unit.
