Controller:

• Technologic Systems TS7800 single board computer running Linux
• Technologic Systems dio24 digital io board
• Dallas Semiconductor DS18S20 3-wire temperature sensors

Software:

• C code to read ds18s20 sensors from a ts7800 single board computer with a dio24 digital input/output board
• C code to set dio24 port on a ts7800
• C code to read dio24 port on a ts7800
• Perl code that runs every minute to use above c programs to decide on and set current system state by reading temps and setting relays which controls the valves and circs
• Perl code that reads log created by above script and creates a graph of tank temps and states vs time
