3. Starting up and stopping the unit
The unit can be put into operation using schedule, extended running switch, forced recirculation switch
or if conditions for free cooling are met. It is possible that few running modes are active at the same
time. In that case the unit runs at running mode which has higher priority.
3.1 Schedule
Access controller has a year-base clock function. This means that a week-schedule with holiday periods
for a full year can be set. The clock has an automatic summertime/wintertime change-over.
Each day has up to two individual running periods. For 24 hour running, set a period to 00:00
–
24:00. To
disable a period, set it to 00:00
–
00:00. If both periods of a day are set to 00:00
–
00:00, the unit will not
run at that speed that day. For 24 hour running, set a period to 00:00
–
24:00.
If you want to run the unit from one day to another, e.g. from Mon 22:00 to Tue 09:00, the desired
running time for both days must be entered.
If the unit shall run at that speed during the holiday period
–
it can also be scheduled here.
There can be up to three independent schedules (one for each fan speed in use). If on/off recirculation is
used with scheduled control, the additional “Extra time channel 4” schedule will be available.
If running periods in schedules overlap, the schedule for the higher speed gets the priority
