(1) External input and demand input
(a) Operation permission and prohibition modes
(Note) With 7-segment display [P07]-[0]
1) Operation permission or operation prohibition mode is switched with the connector (CnS1) and the jumper wire (J13)
on the outdoor PCB.
J13: Switching of CnS1 input method
J13 short-circuited: CNS1 is for the level input.
J13 open: CnS1 is for the pulse input.
2) Operation permission/prohibition control by the external input CnS1 of outdoor unit
Input: CnS1 Switching with J13

Note (1) Factory setting – J13: Short-circuit, CnS1: Short-circuit (Short-circuit pin connected)
3) Remote controller displays the operating conditions, Operation conditions are transferred to optional centralised
controller.
4) When the control comand from remote controller is not accepted (Under the condition of the system all stop status
by external input), “Center” is dispalyed. See Item 5) mentioned below.
5) CnS1 performs the following operations depending on the short-circuit or open of the jumper wire (J13). In case of
pulse input, the pulse width is 500ms or larger.

(Note) With 7-segment [P07] = [1]
1) Demand control and normal operation are switched with the connector (CnS1) and the jumper wire (J13) on the
outdoor PCB.
