Time programming
8.9
The controller has several clocks which allow the individual programming of : Reduced Airflow, Normal
Airflow, Stop.
Holiday periods can be programmed; the transition to summer time is automatic.
A free cooling by night function can be programmed to start the CTA controller outside of programmed
periods.
Clock parameter setting :
Only the operation ranges are programmed (outside these ranges the fans are stopped).
The installer can thus define two operation ranges in normal speed (the default speed or high speed) and
the ‘’reduced‘’ speed (low speed when two speeds are possible).
For each speed, two ranges can be entered per day.
For example :
The High Speed can be defined 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 Low 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 :
In the time menu, before programming the ranges, make sure that the date and time are exact.
It is possible to set on :
To access the fields :
Press the validation button (a cursor appears).
Then with the arrows change the value.
Once the value is obtained, press the validation button again.
After all the fields are entered and the validation button pressed, the cursor disappears.
