Introduction

To be able to use the FCU you will need to join MERG. so you can get the program install files.

  • https://merg.org.uk/

  • You need a login and password to access the site.

  • Link to the page here

  • A short video is now available covering this here,

Stage 1 renegotiate

  • Start the FCU program and have the module connected via a usb lead.
  • To add the module to the FCU you will first need to use the Arduino Ide to send a message via the serial monitor. Type "r" in the message window and press enter on the computer keyboard. This is called "renegotiate"

Stage 2 Node setup FCU

  • You will then see a new window appear from the FCU programme.
  • Here you can see I have the Node Name as Node 1.
  • The Node Number is set as 256.
  • Node Type has picked up the Node Type from the 7 digit name given in the main sketch.

  • Choose what you want the 6 inputs Node Variables to use from the 5 possible choices. 0 is the default in generic mode of the FCU
  • I have set them all to 1 for this example.
