Teamwork Mode

Teamwork 3 mode was set when the solution was implemented. This mode indicates three functions: Standby, Rotation, and

Fan Cascade Control.

Standby Function

When a unit is defined as a standby unit, the unit's fan runs at the default speed of 0%. The standby unit begins to run when a

critical or normal alarm is triggered on the primary unit.

Critical fault alarms

• High pressure lock

• Low pressure lock

• High discharge temperature lock

• Low discharge superheat lock

• Low pressure sensor fail lock

• Compressor drive fail lock

• Fan fail alarm (when the alarm handling is set to shut down)

• Water underfloor alarm (when the alarm handling is set to shut down)

• Power fail alarm

Normal alarms

• High discharge temperature alarm

• Air flow temperature sensor failure

• Air flow loss alarm

• Discharge temperature sensor failure

• Suction temperature sensor failure

• Low pressure sensor failure

• EEV drive communication failure

• Compressor drive communication failure

• Compressor temperature control sensors failure

• Fan temperature control sensors failure

• High supply temperature alarm

• High return temperature alarm

• High remote temperature alarm

RotationFunction

This function ensures that all units have equal runtime. The rotation is preset once every 24 hours.

FanCascade Control Function

This function ensures that a standby unit will start to run if an alarm is triggered on the primary unit, if it was not activated by

system setup.
