(iv) When the control comand from remote control is not accepted (Under the condition of the system all stop status by
external input), “Center” is dispalyed. See Item (v) mentioned below.
(v) 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.

(vi) After changing mode from operation prohibition mode to permission mode, the indoor units operation status can be
select by 7-segment [P17] setting.
7-segment[P17]=0→KeepingSTOP
7-segment[P17]=1→AutomaticallyRUN
(b) Demand control
(Note) With 7-segment [P07] = [1]
(i) Demand control and normal operation are switched with the connector (CnS1) and the jumper wire (J13) on the
outdoor PCB.
J13: Switching of CnS1 input method
J13 short-circuit: CnS1 is for the level input
J13 open: CnS1 is for the pulse input
(ii) Operation/ stop control by the demand input CnS1 of outdoor unit
Input: CnS1 Switching with J13

Note (1) Factory setting – J13: Short-circuit, CnS1: Short-circuit (Short-circuit pin connected)
(iii) The operation condition is desplayed on the LCD of remote control and is transferred to option centralised control.
