Programming of operating temperature
1.
Press [3] and hold for more than 10 sec. upper display will now show -3 -, (lower dis-
play shows the temperature of lower roast system)
2.
Press [1] for the change of the temperature at lower roast system. Change of temper-
ature is done by pressing [+] or [-]. Wait for 5 sec. And the program will save and re-
turn to the menu.

Programming of gain:
Control of over and under heating unit has 2 solid state outputs from the PCB.
The heat management is undertaken as a proportional control, ie. Output is
calculated based on the difference between the actual temperature and T_akt
desired temperature T_set. SSR relay will begin to commute on / off when the tempera-
ture is 3 ° from the set temperature. The speed of this commuting is controlled by the
Gain value.
This results in a rapid heating to operating temperature without a drastic overshoot,
while a quick adjustment up around the desired temperature.
Gain value (amplification factor) can be adjusted in service mode (press 1). Range 0 to
100
1. Press [OFF] - that should now see a line in the upper display.
2. Press [1] and hold for more than 10 sec. upper display will now show -1 -
(lowerdisplay us-ing temperature at lower PTFE tape)
3. Press 1 to change the GAIN value (amplification factor) Factory Setting = 30
Factor is changed by pressing the [+] or [-].
4. The program will return to the menu after 5 seconds. Wait until this happens and
changes are saved.
5. To exit the menu, press [RESET], the machine will turn off.
6. Press [ON] to start the machine.
