Note 3:
S or S4 module can be installed in COMM slot for communication. If relay, TRIAC no contact switch,
or SSR drive voltage output module is installed in COMM, it can be used as alarm output. If I2
module is installed in COMM and parameter

Note 2:
For COMM/AUX slot, if S or S4 communication module is installed, it can be used for
communication; if L2 module is installed in, parameter set bAud = 0, it can be used for AU1 or AU2
alarm output; if set parameter bAud = 2, it can be used for AU1 or AL1 alarm output. If L1, L2, L4,
G, K1, W1 or W2 is installed, it can be the auxiliary output in bidirectional (heating/refrigerating)
control (Auxiliary output doesn

it can input on-off signal to switch SP1 and SP2 (AI-516) or switching the program status RUN /
Stop (AI-516P) by connecting a switch between terminals number 3 and 5.
