14 ALARMS MEMORY

On entry to the alarms memory page the data inherent the last alarm acquired is displayed. Use the
1. ALARM: description of the anomaly
2. INDEX: indicates the alarm index
3. ORIGIN: indicates which element has generated the alarm (Chiller, i_th Fan Coil, DHW, System, VMF-CR, VMF-P1, VMF-P2, VMF-P3, MZC, VMF-REB 1/2/3)
4. DATE TIME: indicates the time and date when the alarm occurred
To delete the alarms log, press the
dure all of the alarms present in EEPROM are removed, otherwise the memory remains unvaried. With complete memory (max 5 alarms), if a new event occurs, the storage
process will automatically delete the oldest alarm and enter the new one under index 10.

Check thermostat room probe
Due to environmental conditions
Due to unfavourable system conditions
Check the VMF-E2/E4 panel attached to the relevant thermostat for proper connection or electrical integrity
Check the inverter functioning or wiring reporting the inverter state to the thermostat
Check correct RS485 bus connection
Check address (1) and the RS485 bus for proper connection.
Due to unfavourable system conditions (heat pump, exchanger or resistance in the storage tank)
Check the resistance for intactness, the status of the magnet circuit breaker in the DHW panel or input (ID1-ICD1 terminal
board J4 of the PCOe in the DHW panel)
Check the connection and status of the water probe
Due to unfavourable system conditions (heat pump or exchanger in the storage tank)
Check the boiler or the presence of the input for reading (ID1-ICD1 terminal board J4 of the PCOe)
Check address (2) and the RS485 bus for proper connection
