Stulz Prodigy IROW DX Operating Instructions Manual page 23

C2020 electronic controller
This electronic microprocessor card is equipped with a set of terminals to connect the card to the
devices it controls (fans...). The operating software and the file containing the operating
parameters are written in the EEPROM so that they remain stored even when there is a cut-off in
the power supply.
The C2020 card is housed inside the electric box and can only control one unit.
A keypad can be connected to the C2020 card to display information regarding operating
conditions, the state of the unit and any alarm. As standard, the keypad for Prodigy iROW is
supplied loose, to be mounted on the rack frame. The keypad is provided with 4 m cable for
connection to the USER socket in the e-box.
C2020 is connected to the controller of external motor-condensing unit, to exchange data for unit
control. Connection is made through a XY interface mounted on PRG port of C2020.
The C2020 card can also be connected to a remote monitoring / supervision system using a
serial line and ordering the necessary options. Serial line for sequencing / telemonitoring is
available on the SLAVE port. For more detail about telemonitoring, please check the
corresponding paragraph.
Refer to the wiring diagram given in part 2 of the manual, which is specific for each
unit, when assigning the C2020 inputs / outputs.
