CHAPTER 3 FUNCTIONS AND OPERATION
1.
DISPLAY PANNEL
Temperature:
The LCD will display the temperature measured by the temperature sensor in the
range of 43
℉~
140
℉
.
Set temperature:
The temperature setting range is 95
℉~
131
℉
and indicated by the 5 red
LEDs besides the LCD. The bottom LED is on when temperature is 95
℉
; the bottom two LEDs are
on when the temperature is within range of 97
℉~
104
℉
; three LEDs are on when temperature is
within range of 106
℉~
113
℉
;four LEDs are on when temperature is within range of 115
℉~
122
℉
; all LEDs are on when temperature is within range of 124
℉~
131
℉
. The default setting
temperature is 109
℉
.
Set time:
The maximum setting time is 60 minutes and the remaining time is indicated by the 5
red LEDs besides the LCD. The bottom LED is on when the remaining working time is 20 minutes
or below; the bottom two LEDs are on when the remaining working time is within range of
20~30minutes; three LEDs are on when the remaining working time is within range of
30~40minutes; four LEDs are on when the remaining working time is within range of 40
~
50
minutes; all LEDs are on when the remaining working time is within range of 50~60 minutes. The
default working time is 45 minutes. If the system is in long-term working mode, the top LED
blinks.
Hint message:
1)
Temperature is lower than 43
℉
:
LCD displays “
-
L
”, detected by the temperature sensor.
2)
Temperature is higher than 140
℉
:
LCD displays “
-
H
”, detected by the temperature
sensor, all heating elements stop working.
3)
Water supply fault:
LCD displays “
-
E
”. This message appears when the water
level is lower than the minimum water level 10 minutes after the system is started and the
water inlet valve is opened, or the water level is lower than the desired level 3 minute after the
water supplementing order is given. It indicates faults of the water supply system, all heating
elements stop working.
4)
Drainage:
LCD displays “
-
d
”, indicating automatic draining after the pre-set job is done
(
ON/OFF
button is pressed or setting time is up), then the whole system will shut down
automatically.
5)
Connection error:
LCD displays “
EE
” showing any connection error between the controller
and the main PCB.
6)
Heating up:
indicated by the three-color LED on the left of the panel with label “
”
.
