Connect a Version 2 controller by Ethernet (video)

Wire a Version 2 controller straight to the router for the fastest, most stable link.

This guide shows you how to connect a Mixergy cylinder with a Version 2 controller straight to the internet with an Ethernet cable. You can recognise a Version 2 controller by its metal cover, and a direct connection gives the fastest and most stable link.

SAFETY

Before you open the controller cover or make any connection, isolate all electrical supplies to the cylinder. The controller label warns of a dual supply, so make sure both supplies are isolated, and follow safe isolation procedure as set out in the installation manual.

Step 1. Find the LAN port

  1. Locate the LAN port on the bottom of the controller. The USB ports, used for the Wi-Fi dongle, are next to it.
  2. Make sure the port is clear and ready for the cable.

Step 2. Test the cable

  1. Check the CAT5e or CAT6 cable with a suitable network tester.
  2. Pins 1 to 8 should light in order at both ends.

Step 3. Connect

  1. Plug the cable into the controller’s LAN port, directly or through a wall plate.
  2. Route the cable neatly out of the cupboard so it is not strained or damaged.
  3. Connect the other end to an active LAN port on the router or network switch, again directly or through a wall plate.
  4. Make sure both ends click firmly into place.

Step 4. Restore power

  1. With the cable secure at both ends, switch the power back on.
LED check
  • The Link LED on the LAN port lights solid amber when the router connection is detected.
  • The Activity LED flashes green to show data is moving.
  • The network indicator on the gauge shows the cylinder is online.
Check it’s connected

The controller detects the wired connection and joins the Mixergy cloud automatically.

  • The gauge shows the network is connected.
  • If the customer has set up the Mixergy app, it shows the cylinder data.
Installer notes

A direct Ethernet connection is ideal where maximum reliability matters, or where wireless or powerline connections are not suitable.

  • Check the cable with a suitable tester.
  • Use CAT6 for long runs.
  • Avoid tight bends or compression points.
  • Make sure the router’s LAN port is active.
  • Label the cable for future servicing.
