(a) Determination of operation mode
(16) Outline of automatic operation
The air-conditioner operation is controlled by releasing the jumper wire (J3) on the indoor PCB and inputting the external sig-
nal into the CnT.
Note (1) Please install the separately-sold interface kit (SC-BIKN-E). Remove the jumper wire (J1 or J3) from the interface kit circuit board.
(a) The operation mode is switched over between permission and prohibition by releasing the jumper wire
(J3) on the indoor PCB.
When the jumper wire (J3) is short circuited
Normal operation is enable (when shipping)
When CnT input is set to ON, the operation starts
and if the input is set to OFF, the operation stops.
For the CnT and remote control inputs, the input
which is activated later has priority and can start and
stop the operation.
When the jumper wire (J3) is released
Permission / Prohibition mode
When CnT input is set to ON, the operation mode is
changed to permission and if input is set to OFF the
operation is prohibited.
(e)
When the unit is operated automatically with the wired remote control connected, the cooling operation is controlled ac-
cording to the display temperatures while the setting temperature is compensated by
+
1°C during dehumidifying or by
+
2°C
during heating.
