COP parameter settings mode
Access to the simplifi ed parameter setting menu (via the password 1111) allows:
• The selection of Normal fl ow and Reduced fl ow of each fan.
• The scaling factor in case one fan is slaved.
• The night set point value of the fans.
The choice between normal and reduced pressure can be performed:
• manually
• automatically with programme schedule (see section Time programming)
• remotely, by external digital contact (see section force normal speed)
A third set point, the “night speed”, may be entered via the control panel. The value
in % corresponds to the percentage of the fan’s maximum pressure; it will be used
during the night for free cooling (see corresponding function).
