Codes de défaut couverts
83-57
This code will be set when any of the VFD compressor speed limiting codes are active and the compressor speed is reduced below the lowest allowable operating speed for a given OAT. Once 1 hour lockout timer expires the unit will attempt to resume operation. This code indicates the compressor requires higher torque (current) to operate at desired rpm and compressor is mechanically damaged. If code persists, replace compressor.
