S&P CADB/T-HE PRO-REG Series Instruction Manual page 29

Depending on the circuit in which the regulation components are located, 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).

In case COP mode is selected, in the Main screen it is showed the actual Pa of the fans with
pressure transmitters and also the speed of the fans (as a percentage of the maximum fan
speed).
