I bought this one
1st run the black plastic boot just melted away
second run the yellow cable that was in the oven turned black and gave off noxious vapours before shorting out completely!
have now ordered one of these
here's my code
features:
- range check thermostat on startup
- hold button 1 at boot to go into button test mode
- hold button 2 at boot to go into thermostat test mode
- button 1 = start
- button 2 = panic stop! (when running - see button 1)
- button 2 = next setting (when not running) loops through settings then back to ready
- button 3 = increment setting
- button 4 = decrement setting
- door button detects door open (not actually connected yet!)
- all settings saved to EEPROM with checksum
- invalid checksum sets deafults and drops to settings mode
- preheat shows actual and target temp, counts timer up until temp reached
- flux increases more slowly, shows actual and target temp, counts down
- ramp increases to reflow temp, actual and target temp, time taken
- cooldown shows actual and target temp and time taken
- door open waits for the door to open
if you find anything missing or make changes do let me know
cheers
Mike
