Hi Richard,

At the moment the code has just been edited to remove the sections for the remaining 3 18B20's - Originally Henrik worked with me and Darrell to provide 4 independent PID routines that was then incorporated into my code to give 4 pulse proportional thermostats. My idea was to save the working code, strip out all the parts I don't need for the lighting, clock etc and just have one working PID routine using a DS18b20, and then remove / adapt that part of the code to use a DHT11, so the end result is a single PID pulse proportional thermostat that reads temperature and humidity and displays that on the LCD.

I've been test compiling as I went along, and up until recently all the errors I had we local to this file and were normaly down to missing variables, or where i had removed a variable that was later required. Why the error is pointing to the lib files in the PBP folder I have no idea
