10. FIELD SETTING
1)
When using the door lock function, the red wire should be cut and connected to the door lock
control switch attached to it (supplied by user), and the connecting wire should be 22AWG or above. In
normal conditions, the unit operates normally once the switch is closed and shuts down once the switch
is off.
2)
When using the fire protection function, the white wire should be cut and connected to the fire
protection lock control switch attached to it (supplied by user), and the connecting wire should be
22AWG or above.
In normal conditions, the unit operates normally once the switch is closed and shuts down once the
switch is off.
3)
When using the ON/OFF function, the white wire should be cut and connected to the door lock control
switch attached to it (supplied by user), and the connecting wire should be 22AWG or above. In
normal conditions, the unit operates normally once the switch is closed and shuts down once the
switch is off.
(2) Timing sequence description:
4)
Access control
1) Control of entrance card disconnection: the air conditioner will shut down if the access control signal
is disconnected for 30 seconds. In this state, the indoor unit cannot start. If the user performs start
operation, the wired controller will not respond and displays power-off status.
2) Control of entrance card connection: after the closed circuit of entrance card interface, power-on
restrictions are released, the wired controller maintains power-off and the startup & shutdown control
is enabled.
●
Fire protection
1) Access to fire protection: the air conditioner will shut down and stop blowing air after the access control
signal is disconnected for 3 seconds. In this state, the indoor unit cannot be started. If the user performs
start operation, the wired controller shall not respond and displays power-off status.
2) Cancellation of fire protection: after the short circuit of fire protection signal, release power-on restrictions,
the wired controller maintains power-off status and the startup & shutdown control is enabled.
●
ON/OFF
1) In the situation where ON/OFF function is enabled, the port is closed and in short circuit, the indoor unit
starts; the indoor unit shuts down once the port is disconnected;
2) Other operation information (such as mode, air speed, air door, and so on.) except for startup &
shutdown can be set through the wired controller, remote-controller and WIFI module, priority is given
to the latest command received.
3) In the mode of ON/OFF function, wired controller, remote-controller, WIFI module and access control
cannot control the unit startup & shutdown, neither the operation mode, timer or sleeping mode.
4) There will be 12V signal output when machine fault occurs.
(3) Relative priorities of instructions
ON/OFF has the highest priority. The access control function shall be disabled when ON/OFF is enabled.
Access control and fire prevention functions shall not affect each other.
