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 at ON.)
*2 In the energy saving mode, the capacity restriction becomes effective even if no signals are input at external input terminals.
*1 Valid/invalid is changed depending on outdoor temperature.
*2 It is always Valid, regardless of outdoor temperature.
Controls of outdoor unit may be selected as follows using the dip switches on the PCB and P

on the 7-segment.
To change P

on the 7-segment, hold down SW8 (7-segement display increment up: 1-digit), SW9 (7-segment increment up: 10-digit) and SW7 (Data write/Enter).

Close the fluid operation valve on outdoor unit and set as follows:
(1) SW5-2 on PCB to ON
(2) SW5-3 on PCB to ON
(3) SW5-1 on PCB to ON
Forced cooling mode
(It can be fixed at cooling with external input terminals open, or at heating with them short-circuited.)
Set external input function
allocation to “2” *1
Set allocation of external
input function to “1” *1
Inputting signals to external input terminals selects the demand mode.
