Example: If customer wants to maintain 150 Pa in the duct, TDP-S must be configured at SW2 = 3 (Pressure range 300
Pa). The setted pressure range must be as minimum twice of the set point.

Once the pressure range on the TDP-S has been configured, the same pressure range has to be setted in the SLIM touch
display following the procedure shown below:
The access to the configuration menu of the COP mode is performed following the sequence:
Depending on the circuit in which the regulation elements are located, it is possible to choose among two COP control
modes:
• Pressure control in supply fan (SAF), while extract fan (EAF) works as slave: SAF is controlled by the pressure transmi-
tter signal and EAF follows SAF by a balance factor (parameter “%exhaust/supply”). One pressure transmitter (SPRD
/ TPD-S accessory) is needed at supply.
• Pressure control in extract fan (EAF), while supply fan (SAF) works as slave: EAF is controlled by the pressure trans-
mitter signal and SAF follows EAF by a balance factor (parameter “%supply/exhaust”). One pressure transmitter
(SPRD / TPD-S accessory) is needed at extraction.
