thanks ray for the reply
the unit is 2.2u
button B1 brings up black boxes with some characters top right hand side after the unit finishes showing CONNECTING but no IP address
Button B2 shows a MAC address
controller seems to be working i can reset etc and manually set everything from B3 at start up however it will not let me connect and it just stopped controlling the valves by itself it has been functioning for months with no problems
ill see if i can find a way to post some pictures
