2. When a CNT communicaon error is detected on the backup unit, both running unit and
backup unit will connue its previous state (no signal sent from remocon) with rotaon
counter cleared.
3. When a system error (indicated by mer LED blinking) is detected on the running unit and the
running unit is turned off by indoor control due to error detecon, backup unit will be turned
on by remocon with rotaon counter cleared.
4. When a system error detected on the backup unit and it is turned off by indoor control due to
error detecon, rotaon counter is cleared.
B. Unit response when error is cleared during duty rotaon
1. When CNT communicaon error detected on the running unit is cleared, the running unit will
connue running and backup unit will be turned off by remocon. Rotaon counter will restart.
2. When CNT communicaon error detected on the backup unit is cleared, the running unit will
connue running and backup unit will be turned off by remocon. Rotaon counter will restart.
3. When system error detected on the running unit or backup unit is solved, the running unit or
backup unit may not turn ON (Timer LED is sll blinking) as the error is sll memorised in the
indoor unit. It is required to reacvate the duty rotaon manually.
C. Unit response aer recovery from power breakdown
Duty rotaon will resume and Main unit will become running unit, Sub unit will become the backup
unit. Rotaon counter will start anew.
10.4 Setting thru WLAN prohibition control (Indoor control)
Purpose:
During duty rotaon mode, wired remote control will repevely send a CN-CNT signal to indoor unit
based on a me interval, and indoor unit will send feedback signal to wired remote control for wired
remote control to compare and verify signal. It is important to prevent wifi seng change signal from
wifi app from clashing with the CN-CNT signal and disrupt duty rotaon.
Wired remote control will set Seng change thro’ WLAN Flag by CN-CNT signal.
1. When Seng change thro’ WLAN Flag = Disable, indoor unit should ignore all seng change
(including AI ON/OFF seng) through wifi app.
2. When Seng change thro’ WLAN Flag = Enable, indoor unit should accept all seng change
(including AI ON/OFF seng) through wifi app.
(Note: WLAN feature/operaon is not disabled at any condions, user is sll able to monitor unit
through Wi-Fi app)
