A06
This alarm indicates when the water injection sensor is damaged or broken.
A10
This alarm indicates when there is a problem with
or water flow problem.
A12
This alarm usually appears together with the A10 alarm as it depends on the configuration to which the pump was com-
missioned, otherwise the current equipment containing this controller simply has a pump configured in this case this alarm
goes together with the current pump configuration.

This alarm usually appears when the water temperature does not drop due to the current cooling process. This alarm is
more of a warning than a serious alarm as it is simply an indicator that the equipment is not cooling and therefore the water
temperature is not dropping.

A21
This alarm indicates when the suction temperature probe is broken or disconnected.
A25
This alarm indicates when the high pressure switch has suffered a change in its signal.
