Chiller Status Alarm

A chiller status alarm  can be a chiller on-alarm or a chiller off-alarm.

A chiller on alarm is generated when the chiller is commanded off and the status is on after the time delay defined by ALM-05. The chiller on alarm is automatically reset. The chiller module is able to start up if a chiller on-alarm is active.

A chiller off alarm is generated when the chiller is commanded on and the status is off after the time delay defined by ALM-05. The chiller off alarm must be reset (manually or automatically)

The chiller on alarm is displayed by DISP-10.

The chiller off alarm is displayed by DISP-09.

The chiller status alarm is displayed by DISP-05.
