Alarm Indications (cont)

A09

Overheat preventive operation malfunction Auto-reset: When operation mode is changed

 

 

A11

Release preventive operation malfunction This alarm occurs when the Hydro Unit enters the forced-

stop zone 10 times.

 

 

Self-hydro unit is stopped due to alarm of other hydro unit. When alarm occurs in an hydro unit in the

 

group, other hydro units must also be stopped with refrigerant control.

P31

When alarm E03, L03 or L07 occurs in the header unit in the group, other hydro units must also be

stopped

 

 

because they do not know which header unit (remote controller) to follow.

 

Auto-reset: When the first alarm is reset
