  • Page 86 9-9-7. Fan Operation Check in Outdoor Unit This function is provided to check the fan operation of the outdoor unit by using switches on the interface P.C. board in the outdoor unit. The fan speed can be controlled by setting of the switches. Use this function to check the operation or abnormal sound in the fan system.
  • Page 87 9-9-8. Abnormal Outdoor Unit Discrimination Method By Fan Operating Function This function is provided to forcedly operate the fan of the outdoor unit in which a check code occurred or the fan of the normal outdoor unit by the switch operation on the interface P.C. board in the header unit. To specify which one of the follower units connected to the system had problem, use this function for the system stop due to a follower unit problem (Check code [E28]).
  • Page 88 9-9-9. Manual Adjustment Function of Outside Temperature (TO) Sensor This function is provided to fix TO sensor value manually by the switch operation on the interface P.C. board in the outdoor unit. When the unit stops abnormally due to TO sensor failure, etc, an emergent operation is available by setting up the value manually to position near the current outside temperature.
  • Page 89 9-9-10. Refrigerant leakage detection The refrigerant leakage can be confirmed by using the switches on Interface P.C.board of the outdoor unit. If there is a leak, the location must be found in order to recover the refrigerant. After that, implement appropriate countermeasure and refill the refrigerant to its standard volume. Refrigerant leaks can be detected by comparing the Actual opening of PMV with the Calculated opening of PMV* during the operation.
