"2" : Cooling/heating forced input
"3" : Silent mode input

"7" : Test run external input 2 (equivalent to SW5-2)
"8" : Silent mode 2
"9" : Spare

By changing the allocation of external input functions (P07-19) on the 7-segment, functions of external

input terminals may be selected. Inputting signals to external input terminals enable the following functions.

"0" : Operation output
"1" : Error output
"2" : Compressor ON output
"3" : Fan ON output
"4-9" : Spare

The external output function of CnZ1 can be changed by

changing the setting in P06 on the 7 segment display panel.

7-3. External input and output terminals specifications

*1 Control is switched when both the allocation of external input function (P07-10) and SW are changed.

(Example: To use CnS1 for the input of forced cooling mode, set P07 at 2 and SW3-7 at ON. To use CnS2 for the input of forced cooling mode, set P08 at 2 and SW3-7 atON.)

*2 In the energy saving mode, the capacity restriction becomes effective even if no signals are input at external input terminals.
