Action Required

 

 

Group Configuration Invalid

• Check that the # Systems setting (Path: Main > Setup > Group > Group

 

Config) agrees with the actual number of Systems connected to the Group.

 

Adjust this setting to match the number of connected Systems.

 

 

Group Configuration Conflict

• Verify the Group configuration settings (Path: Main > Setup > Group) are

 

correct. The Group detected that one or more Systems in the Group have

 

different Group configuration settings and changed the settings of that

 

System.

 

 

Group Fatal Fire Shutdown

• Check the Systems in this Group for fire alarms. The Group Fatal Fire

 

Shutdown occurs only when the Group Fire Alarm configuration setting

 

(Path: Main > Setup > Group Config > Grp Fire Alrm) is On. While the

 

fire alarm is active, the Group will remain shut down.

 

 

Group Fatal Smoke Shutdown

• Check the Systems in this Group for smoke alarms. The Group Fatal Smoke

 

Shutdown occurs only when the Group Smoke Alarm configuration setting

 

(Path: Main > Setup > Group Config > Grp Smoke Alrm) is On. While

 

the smoke alarm is active, the Group will remain shut down.

 

 

Head Pressure High

• Confirm that the air-cooled condenser is operating properly and that the

 

setpoints are correct.

 

• For water/glycol configuration, confirm that the condenser loop pumps are

 

operating properly.

 

• Ensure that the air-cooled condenser is free from debris on the air intake side.

 

• Verify that all isolation valves to the condenser loop or interconnecting

 

piping are open.

 

• For water/glycol cooled configuration, confirm that all air has been purged

 

from the condenser loop.

 

• For water/glycol cooled configuration, confirm that the glycol-to-water

 

concentration is 40% glycol to 60% water.

 

• Verify (water/glycol) cooled configuration, confirm the indoor Module and

 

outside heat exchanger that interconnects between the wiring.

 

• Verify (water/glycol) correct operation of the condenser fluid valve actuator.

 

• Confirm proper refrigerant charge in the Module.

 

• Ensure that the Module is set to the proper heat of rejection method on the

 

display interface (Path: Main Menu > Setup > System # > System Config

 

> System Options).

 

• Verify (water/glycol) cooled configuration, that the strainers are clear and

 

open.

 

• Confirm the proper operation and trip point of the high head pressure switch.

 

• Evaluate field piping for proper line sizes and proper installation.

 

• Verify that the Economizer isolator valve is open (if installed).

 

 

Heater Requires Maintenance

• Verify the operation of the heater and perform preventive maintenance.

 

• Reset the maintenance alarm for the heater at the display interface.

 

 

Humidifier Current High

• Verify that the proper voltage is being applied to the humidifier cylinder.

 

• Confirm that there are secure and proper line voltage connections to the

 

humidifier cylinder.

 

• Ensure that the humidifier water supply has not been conditioned.

 

Conditioning can increase the water conductivity.

 

• Check the electrodes in the humidifier cylinder for mineral buildup that

 

bridges the electrodes.

 

• Check the fill valve for debris which may prevent the valve from closing.
