9.1. An example to show the function of the weekly timer
1) Take the indoor unit of the air conditioner with an address "04" for
example, set the weekly timer
schedules and start up the weekly timer function according to the
above operation. The specific setting
schedules is as shown in the table below:
Table.9-1
Period 1 Period 2
Time on =07:30 Time on =18:30
Time off =18:00 Time off =21:00
Monday Mode = cool Mode= Fan-only
Temp = 24 Temp =
Fan = High Fan = High
Time on =07:30 Time on =18:30
Time off =18:00 Time off =19:00
Tuesday Mode = cool Mode = Off
Temp = 24 Temp =
Fan = Low Fan =
From the above table we can see an indoor unit has a weekly timer
schedule set for two days of Monday and period 1 of Tuesday. If
the weekly timer function has been set, the corresponding unit will
automatically come on according to the above schedule.
Notes to the schedule of period 1 of Monday: The startup time is
07:30 and shutdown time is 18:30. The running mode is cool with
24 degree and high Speed.
If the air conditioning unit is operating according to the schedule and
you wish to alter the mode, you can do so either by the centralised
controller or a local controller. When the next schedule starts the
parameters will revert to scheduled parameters.
If the set mode of a period of the air conditioner is Off, it means the
weekly timer function of the period is invalid. For example, the set
mode of period 2 of Tuesday is Off, which shows that the set weekly
timer function of the period is invalid.
