Constant Pressure Operation (Cop) - S&P CADB/T-N PRO-REG Instrucciones De Uso

10.2.3. Constant pressure operation (COP)

Mode recommended in a multi-area confi guration for variable airfl ow applications
with several modulation systems of the airfl ows installed at the network level.
Airfl ows automatically modulated to maintain a constant pressure value measured by an out-
door pressure sensor.
It is possible to choose among three COP control modes:
• SAF pressure control with EAF slave: SAF is controlled by the pressure transmitter signal
and EAF follows SAF by a scaling factor (parameter Exhaust factor). One pressure transmit-
ter is needed at supply.
• EAF pressure control with SAF slave: EAF is controlled by the pressure transmitter signal
and SAF follows EAF by a scaling factor (parameter Supply factor). One pressure transmitter
is needed at extraction.
• Independent SAF and EAF pressure control: SAF and EAF are controlled each one by its
respective pressure transmitter signal. Two pressure transmitters are needed (supply and
extraction).
