2.
Press the key with arrow up (
˄
) to increase the temperature, press the key with
arrow down (
˅
) to decrease the temperature.
3.
When you have set the temperature as desired refrain from touching any key;
after a few seconds the regulator will return to its normal operation and will bring
the boiler to its newly set temperature (mind you, cooling down to a lower set
temperature will take longer than heating up the coffee boiler).
Note!
The temperature of the coffee water is measured by a probe in the coffee boiler. The
temperature reading on the PID is thus the temperature within the boiler. The
temperature of the water that leaves the group at the group screen on top of the coffee
bed will be 2.5 to 3 degrees lower. You may account for this when fine-tuning the
temperature setting on the PID.
Procedure to adjust temperature offset
1.
Press the P key on the PID shortly. The display will alternating show “SP” (set
point) and the currently set temperature value.
2.
Press the P key for more than 2 seconds. The display will alternating show “AL”
and the currently set value (1.0).
3.
Press the P key several times shortly until “Y .0” is displayed, alternating with its
set value (0).
4.
Press the P key for more than 2 seconds. The display will alternating show
“C111” and the currently set value (001).
5.
Press the P key several times shortly until “OFFS” is displayed, alternating with
the currently set value (0.0).
6.
With the arrow keys you may set the offset value.
When you adjust to -2.5, the display will show the boiler temperature minus 2.5
degrees Centigrade, That is approximately the temperature difference between
the coffee boiler temperature and the group screen.
7.
Press the P key to confirm the newly set value.
8.
When all keys remain untouched for approximately 10 seconds, the PID will return
to its operating state.
See “PID-parameter settings” for original factory settings of all parameters.
Steam boiler
The electronic temperature regulator of the steam boiler is positioned in the back of the
machine on the left hand side (see figure 6).
Warning!
Parts of the interior of the machine will have a temperature (nearly) as high as the set
temperature of the steam boiler. Take the necessary precautions.
Procedure to set the temperature in the steam boiler
1.
Remove the left hand side panel from the machine, a 13 mm spanner is needed
for the nuts.
2.
Press the P key on the regulator until “AL1” appears on the display (it will
alternate with the set value of AL1).
3.
Press the P key again, the display will now read “AL2”, alternating with the set
value for AL2.
