PRELIMINARY NOTES FOR THE INSTALLER: COMPARISON BETWEEN pCO
• the pCO 3 family controllers do not have the connector using the programming key code PCO201KEY0. To program the controller, use the new Smart
Key (PCOS00AKY0) available from September 2005. Otherwise use WinLoad ver. 3.35 and higher:
An application cannot be run from the Smart Key;

• unlike the pCO , there is no fuse between J1 and J2. All pCO
No external fuse is required;
• a further terminal J24 (in place of the fuse) is provided for the power supply to the ratiometric probes (+5 VREF), as well as 20 Vdc to supply a secondary
terminal, such as the aria terminal (TAT***), in alternative to the standard one;
• the terminal J11 (connection to the pLAN network) in the fi rst prototypes of the pCO
• the LEDs near the dipswitches for setting the pLAN address have been moved between connectors J3 and J4;
• the red probe power supply overload LED has been removed.

The pCO controller does NOT have dipswitches for setting the pLAN address. The address must be set by software, as for the pCO
The procedure is as follows:
1. switch the pCO 3 off;
2. prepare a standard Carel terminal with the address set to 0 (not necessary if the pCO

3. connect the terminal to the pCO
4. disconnect any other devices connected in the pLAN from the pCO
5. switch the pCO 3 on, pressing the UP + ALARM buttons at the same time. This combination of buttons is the same on the built in terminal.
Alternatively, on the PCOT terminals, use the combination of the

The default value of the address is 32.
The address of the terminal can only be set after having connected the power supply via the telephone connector.
To enter confi guration mode, press the  buttons at the same time (even when the terminal is already on), in all the versions, for at least 5 seconds;
