5. Main function
4) Power-out compensation function
●
If power is out on selected process, the process before power out is stored to EEPROM, once power is back
the process before power out continues.
●
When power is back, washing process starts from the process at the point of the power out, rinse/drain process
starts from the initial process.
5) Water heater Error function
① This function starts working, when the heater works abnormally.
(this function begins sensing the heater 1 minutes later, after the heater operating)
② The value of the initial thermistor(A1) is compared with that of the thermistor(A2) in 2 minutes (Y=A2-A1)
- For 10 minutes, the variance of temperature(Y) is less than 2
℃
"course led 6ea on 40
℃
/60
℃
led on"
message is displayed on the panel.
③
The value of the initial thermistor(A1) is compared with that of the thermistor(A2) in 2 minutes (Y=A2-A1)
- For 2 minute the variance of temperature increases more than 4.5
℃ (0.2148V) "course led 6ea on cold/60 ℃
led on" message is displayed on the panel.
④ At this time heater, Error "course led 6ea on cold/60 ℃ led on" is displayed and all working process off
⑤
The heater operating continues during heating hours, if washing hour is left over, the residual washing process
keeps going without heating.
