Possible causes

When no ACK signal is detected in 6 interval by transmission side controller, error. Note : The address/attribute shown controller not providing the Cause (1) Poor contact of transmission line of OC or BC. (2) Damping of transmission line voltage/signal by acceptable range of transmission wiring exceeded. Farthest: Less than 200m Remote controller wiring: Less than 10m (3) Erroneous sizing of transmission line (Not within the range below). Wire diameter: 1.25mm2 or more (4) Faulty control circuit board of OC. (1) When IC unit address is changed or modified during operation. (2) Faulty or disconnection of transmission wiring of IC. (3) Disconnection of IC unit connector (CN2M). (4) Faulty IC unit controller. (5) Faulty remote controller. (1) Faulty transmission wiring at IC unit side. (2) Faulty transmission wiring of RC. (3) When remote controller address is changed or modified during operation. (4) Faulty remote controller. detecting method As same that for single refrigerant system. (1) Cause of (1) ~ (5) of “Cause for single refrigerant system”. (2) Disconnection or short circuit of transmission line of OC terminal block for centralized control (TB7). (3) Shut down of OC unit power source of one refrigerant system. (4) Neglecting insertion of OC unit power supply connector (CN40). (5) Inserting more than 2 sets of power supply connector (CN40) for centralized control use. For generation after normal operation conducted once, the following causes can be considered. • Total
