Cooling Fire Shutdown Test The cooling (COOL) submenu is used to change output status for testing the cooling function. The fans (FANS) and heating (HEAT) service test outputs are reset to OFF for the cooling service test. The digital scroll controller power test (CTLR) turns on and off the compressor controller. The compressor capacity test (CPAC) is used to run the compressor at a desired capacity of 15% to 100%. If a capacity is chosen between 1 and 14, the capacity will be set to 15%.

Thermistor Troubleshooting The electronic control uses thermistors to sense temperatures used to control operation of the unit. Resistances at various temperatures are listed in Table 15-17. Thermistor pin connection points are shown in the Maior System Components section. The general locations of the thermistors are shown the Maior System Components section. Air Temperatures Air temperatures are measured with 10 kilo-ohm thermistors.
Sensor Trim Corrective offsets can be applied to the space temperature and the supply air temperature sensor readings. These corrections are set in the Configuration--,TRIM menu for the display, or in the Maintenance--,TRIM section for available table for CCN. See the Indoor Air Quality adjustments to IAQ and OAQ sensor readings. The space temperature calibration temperature may value be corrected by entering either a in SPT.C, or an offset temperature value in SPT.T.

APPENDIX B - VFD INFORMATION On 48/50PD units, the supply fan speed is controlled by a 3-phase VFD. The VFD is located in the supply fan section behind an The VFD condensation indoor fan scroll. The VFD speed is controlled directly by the ComfortLink controls through a 0-10Vdc signal based on a is stopped is powered during normal operation to prevent from forming on the boards during the off mode and by driving space temperature sensor.

VFD Maintenance History For reference, 0401, 0412, the last three fault codes are stored into parameters 0413. For the most recent fault (identified by parameter 0401), the drive stores additional data (in parameters 0402 through 0411) to aid in troubleshooting a problem. For example, a parameter 0404 stores the motor speed at the time of the fault. To clear the fault parameters), history (all of Group 04, Fault History follow these steps: 1. In the 0401.
