In case of using or cancelling the room card control / fire protection / (ON/OFF) function, use the wire
controller to modify the parameters of indoor unit.
2. Function introduction
(1) Room card control: a kind of control mode to control the machine startup & shutdown based on the on & off
state of the room card control port.
(2) Fire protection: a kind of control mode to control the machine startup & shutdown based on the on & off state
of the fire protection port.
(3) ON/OFF function: a kind of special control mode to achieve the control of indoor unit startup & shutdown
based on the input state of the fire protection port of the indoor unit (no other way can control startup &
shutdown) and output the fault status of indoor unit through OUT INPUT port.
3. Function setting
3.1 Hardware connection
3 pins of the OUT INPUT CN16 socket shown in the electrical wiring diagram of Figure 1 are tacitly approved
to be in short circuit state under the factory state (an external short circuit plug shown as Figure 2), and the OUT
INPUT CN16 socket of main control board is shown as Figure 3.
(Illustration: the socket number in circuit is subject to the actual serial number of PCB.)
4) When using the room card control or fire protection, the user cuts off the short wire shown in Figure 2 and
connects the red line and the black line to the control switch (supplied by user), and the connecting wire
should be 22AWG or above specification. The switch is closed under normal conditions and off under
abnormal conditions.
5) When using the ON/OFF function, the user cuts off the short wire shown in Figure 2 and connects the black
line and the white line to the ON/OFF control switch (supplied by user), and the connecting wire should be
22AWG or above specification. In normal conditions, the machine starts once the switch is closed and the
machine shuts down once the switch is off.
