3. STARTING TO WORK
After turning the supply on, the controller carries out
the display test, displays the
re71
,
inscription, the program version
and next, displays the measured and set value.
A character message informing about abnormalities may appear
on the display (table 4 - see full version of service manual, available
at www.lumel.com.pl). The On-Off control algorithm with hysteresis gi-
ven in the table 2 (full version of service manual) is set by the manufac-
turer.
Changing the Set Point Value
The set point value is displayed after pressing the
or
the
button, then the SP diode is lighting. In order to change the
set value, one must press the
or
button again (fig. 6). The
beginning of the change is signaled by the dot flickering on the display.
One must accept the new set point value by the
button in the laps
of 30 seconds from the last pressure of the
or
button, in the
opposite case, the controller transits to display the measured value with
the previously set up set point value.
