Hi

Thank you for the sample program i have had a go with this into the systems and it works great i have tweaked some of the scaling settings to whats need for the system.

I also had to set some extra settings on the temp controller for the probe to read correctly with the real time temp to get the correct reading at the logo.

The problem i think is that i can get the analogues to switch not a problem while creating these programs its the scaling that i struggle with and the setting up of the analogue signal that i struggle with.

Once again thanks for the point in the right direction
