HI OWEN I THINK I WILL JUST STICK TO THE SAME DIAGRAM PICTURE AND WIRING YOU SENT TO ME WITH THE SAME TYPE RELAY YOU SPECIFY AND THEN CONFIG THE CODE IN THE CONFIG.gfile AS YOU SHOW TO CONTROL FAN0 ON AND OFF .
I WILL POSSIBLY SEND BACK OTHER RELAYS OR MAY KEEP HOLD OF THEM.
REGARDING THE T H C I MAY USE A FLOATING HEAD TYPE SETUP OR A PROBE FINGERS CROSSED.
THAANKS FOR ALL YOUR HELP
HAVE A GOODAY OR EVINING ALL THE BEST MIKE SPK SOON
