No. Detail information

Detection of current of the compressor A1 (Protection code P4).

Detection of current of the compressor B1 (Protection code P5).

Current is not detected within the initial 5 seconds after the compressor is started up. When the current of the compressor is

detected to exceed protective value set (18A for constant speed compressor), it will be shut down and re-started after 3

min.

T4: outdoor ambient temperature sensor (Fault code E7).

T3B: pipe temperature sensor of the condenser B (Fault code E6 and protection code P7).

T3A: pipe temperature sensor of the condenser A (Fault code E5 and protection code P6).

1) T4: if there is one system that requires starting outdoor fans, the fans are started through electric control of the unit. Start

outdoor fan A only, start A and B gears, and control the unit through T4.

2) T3B and T3A: when the electric control of the unit detects the temperature of the outdoor pipe T3A or T3B of the system

exceeds the protective temperature 65 , the corresponding system will be shut down. And it will be re-started up, after the
