B2 above set Temp.: Y2 active
B2 below set Temp.: Y2 not active Y2 active: 230VAC, X19:(2-4)
Y2 not active: 0VAC, X19:(2-4)
Hot Air supply (8 sec off - 8 sec. on) Cabinet sensor B1
SSR active: 12VDC X24:(7-8)+(3-4)
SSR not active: 0VDC X24:(7-8)+(3-4) Decision of Hot Air supply by PCB

Steam supply (8 sec on - 8 sec off) Quenching sensor B2
SSR active: 12VDC X24:(1-2)+(5-6)
SSR not active: 0VDC X24:(1-2)+(5-6)
After reaching temperature steam
saturation is calculated by internal
logic via B1 and B2
Timer starts after successful preheating Logic on PCB Blinking dot in timer display
Preheat steam generator 85°C (185°F);
SSR are energized Thermocouple B5 inside
Steam Generator SSR active: 12VDC X24:(1-2)+(5-6)
SSR not active: 0VDC X24:(1-2)+(5-6) Heating elements de-energize
when B5 above 180°C (356°F)
Check water level inside steam generator
Level electrode S2 inside
Steam Generator X12:(1-4) > 2VAC => no water
X12:(1-4) ~ 0VAC => water
