xPress were quick to help me get this sorted, Adkins called me late on a Friday which I thought was great.
Here's the procedure.
Allow press to heat to a set temperature - I used 200c.
Push 'DOWN' and then 'UP' in quick succession FOUR times (Actually arrow pointing right and arrow pointing up in my case) until 'ADJ' displays:

Measure the actual temperature of your Platen - I use an Infra Red Thermometer. Get the average temp of all parts of the platen (Mine varied only 2c) .
Use the arrow on the right (Pointing up) to increase the displayed temperature reading, or the arrow on the left (Pointing Right) to decrease - when it displays the actual temperature of the Platen push 'Mode' to set it.
This has worked for me, the only problem is I have seen 'H-F' on the display a couple of times and I have no idea what this means. I will be back in contact with Adkins in order to make sure everything is ok.
******** Update ***********
I received a new controller board quite quickly from Adkins, this was Friday afternoon and by the time I had fitted it the Adkins staff had gone home.
I was still having no joy so today I called the engineer - there were a small number of these presses that were sent out that hadn't been calibrated so I was given the procedure:

There is a Jumper top right (J8 & J10) - you need to find another jumper and put it over J8 (completing the circuit between the two pins of J8) - you need to LEAVE the jumper ON J10. so when doing this procedure you have BOTH J8 and J10 with the black jumper bridges on. (You can find another Jumper bridge on the back of a hard drive - they are all the same).
You can do this without taking the controller case completely apart - just use a long pair of Tweezers to put on and take off the jumper bridge.
Put it together enough so you cant touch any live components inside when you power it up again - turn it on.
Procedure:
Push 'Mode' Button EIGHT TIMES until 100 is displayed.
Use the > button to select each character as you usually do when setting times/temps - set the display to read 160.
Push 'Mode' to confirm.
Remove Power Cable.
Open the case again and remove the jumper on J8 (the top one of the Two) - out the case back together properly.
Turn the press on - set the temp to anything - I use 100c for testing. allow Platen to reach 100 and check the temp of the Platen - if it is out go back to the first procedure in this post to adjust the temp.
If the press will not reach 100 (or what ever you set it at) - then you may have to send it back to Adkins.
I am having to send mine back.
