11.6. TIME PROGRAMMING
The controller has several clocks which allow the individual programming of: Normal
Speed, Reduced Speed and Stop.
Speed selection is not available in VAV mode.
Normal speed: corresponding to normal pressure in COP mode and to normal fl ow in CAV
mode
Reduced speed: corresponding to reduced pressure in COP mode and to reduced fl ow in
CAV mode
Clock parameter setting:
The programmer works for intervals (outside these intervals the fans are stopped).
The installer can thus defi ne two operation intervals in normal speed (only in CAV and COP
modes).
It is possible defi ne the maximum of the two intervals per day and of speed.
For example:
The Normal Speed can be defi ned from 8:00 am to 12:00 pm in period 1
and from 2:00 pm to 6:00 pm in period 2
and the Reduced Speed from 6:00 am to 8:00 am in period 1
and from 12:00 pm to 9:00 pm in period 2
The programmable logic controller will then control the fans as follows:
To access to the programme schedule, select “Time settings” in the advance parameters.
