FCP manual
Direct/Reverse control
This function is used to reverse the control logic, switching from Direct mode (an increase in the controlled pressure/temperature increases the value of the output)
normally used to control the condensing fan speed, to Reverse mode (an increase in the controlled pressure/temperature decreases the value of the output).
Slave mode
This function is used to disable the internal control algorithm and manage the output directly based on an external signal.
Serial connection
An RS485 serial output is available for connection via two wires plus shield to the supervisor or telemaintenance network that support the Carel supervisor protocol or
®
the Modbus
protocol.
Phase control function
The control of the power section can be modified to adapt it to the type of load.
Index of protection
The gasket inside and the materials used to make the case guarantee the controller IP54 index of protection
Fastening
The device is fastened using 4 screws.
CE mark/Electromagnetic compatibility
The FCP controller is compliant with the EU standards on electromagnetic compatibility, while quality and safety are ensured by the CAREL ISO 9001 certified design
and production system and by the CE mark on the product.
2. User interface
The status of the controller is displayed using LEDs that are only visible with the cover open.
The LEDs indicate:
- power on;
- serial connection status;
- alarm status.
To set the operation of the controller, 4 trimmers and 4 dipswitches are available for the main functions, while internal parameters are used to set all the other
functions. The parameters can be set using the programming key, while access to the parameters for display and setting, as well as access to the variables that
represent the status of the controller, is available via serial line.
