I. ECONOMI$ER+ TROUBLESHOOTING

The EconoMi$er+ control has built-in diagnostics. The con- trol can detect and display 10 different diagnostic codes as shown in Table 37. The user can also use the integrated dis- play to check the status of all the inputs and outputs and run the manual control mode to check the operation of the EconoMi$er+ and compressors.

A. Error Code 1 — SAT Sensor Failure

Error Criteria

An SAT Sensor Failure error will occur if the sensor is shorted or faulty. If the measured temperature reads below –40 F or above 250 F an error will occur.

Required Action

If an error occurs, then the control will default to Mode 2 compressor stage control where Y1 and Y2 have direct con- trol of the compressors. Use of free cooling is disabled and the EconoMi$er+ will be set to the minimum damper posi- tion for either the occupied or unoccupied mode of operation. Replace sensor if faulty.

Reset Method

The error will automatically reset after the value has returned to a normal level. The alarm has to be cleared from the display in the Setup mode or a power reset.

B. Error Code 2 — RAT Sensor Failure

Error Criteria

The RAT Sensor failure error is only applicable the unit has been configured for EconoMi$er+ changeover methods 3 (dif- ferential dry bulb) or 5 (differential humidity). For other modes it should be ignored. If the sensor is shorted or faulty, then the measured temperature will be below –40 F or above 250 F and the error will occur.

Required Action

If this error occurs, then change the default EconoMi$er+ changeover control to method 2 (dry bulb changeover con- trol) or replace sensor.

Reset Method

This error will automatically reset after the value has returned to a normal level. The alarm will have to be cleared from the display in the Setup mode.

C. Error Code 3 — OAT Sensor Failure

Error Criteria

An OAT Sensor Failure error occurs if the sensor is shorted or faulty, then the measured temperature will be below –40 F or above 250 F.

Required Action

—If this error occurs disable the economizer and set the economizer to the minimum economizer position.

Reset Method

This error should automatically reset after the value has returned to a normal level. The alarm will have to be cleared from the display in the Setup mode or by a power reset.

D. Error Code 4 — ORH (Outdoor Relative Humidity) Sensor Failure

Error Criteria

If the unit is configured for economizer changeover type 3 or 4, and the input signal is less than 2 mA or greater than 22 mA, then the sensor is faulty and an error will occur.

Required Action

If this error occurs, switch the EconoMi$er+ to dry bulb changeover control.

Reset Method

This error should automatically reset after the value has returned to a normal level. The alarm will have to be cleared from the display in the Setup mode or by a power reset.

E.Error Code 5 — IRH (Indoor Relative Humidity) Sensor Failure

Error Criteria

This error occurs if the unit is configured for EconoMi$er+ changeover type 5 and the input signal is less than 2 mA or greater than 22 mA (faulty sensor).

Required Action

If this error occurs, switch the EconoMi$er+ to differential dry bulb changeover control.

Reset Method

This error should automatically reset after the value has returned to a normal level. The alarm will have to be cleared from the display in the Setup mode or by a power reset.

F. Error Code 6 — IAQ Sensor Failure

Error Criteria

This error occurs if the unit is configured for IAQ demand ventilation control and the input signal is less than 2 mA or greater than 22 mA (faulty sensor).

Required Action

If this error occurs, disable the IAQ control routine and default to the standard EconoMi$er+ minimum position.

Reset Method

This error should automatically reset after the value has returned to a normal level. The alarm will have to be cleared from the display in the Setup mode or by a power reset.

G. Error Code 7 — Y2 On with Y1 Off

Error Criteria

This error occurs if Y2 is turned on and Y1 is off. This indi- cates that there is a wiring error at the thermostat connec- tions. This alarm should be ignored for the first 20 seconds of operation so that it does not conflict with the special produc- tion test mode.
