A separate alarm log stores the last 25 alarms to occur. When an alarm occurs, it is put into
the first slot in the alarm log and all others are moved down one, dropping the last alarm. In
the alarm log, the date and time the alarm occurred are stored, as well as a list of other
parameters. These parameters include unit state, OAT, LWT, and EWT for all alarms. If the
alarm is a circuit alarm, then the circuit state, refrigerant pressures and temperatures, EXV
control state, EXV position, slide position, and number of fans on are also stored.
To view alarms, activate the manager password, press Menu on the unit controller, then
select Alarm (left arrow), then select Active or Log.
Event Logging
An event log similar to the alarm log holds the last 25 events to occur. When an event
occurs, it is put into the first slot in the event log and all other entries are moved down one,
dropping the last event. Each entry in the event log includes an event description, as well as
the time and date of the occurrence. No additional parameters are logged for events.
To view events, press Menu on the unit controller, then select Alarm (left arrow), then scroll
left to Event Log. See menu matrix on page 40.
