Temperature zero calibration
If you replace the temperature sensor you may find that it is necessary to re-calibrate the
temperature.
This is the procedure:
The whole turbine must be at room temperature (approx. 21°C) !!!
Press and hold the "Select Menu" button on the GSU, then switch on the Jet-tronic (via the
receiver switch).
Note: You can also use the small button on the LED board instead of the "Select Menu"
button on the GSU.
Initially the three LEDs will flash in the following sequence:
LED
Standby
Pump running
OK
(while the LEDs are flashing in this sequence hold the button pressed - don't release it !!!!.)
Release the button only when the three LEDs start flashing in the following sequence:
LED
Standby
Pump running
OK
The GSU screen then simultaneously displays the message:
Release key to:
Calibrate Temp
This terminates the Temperature zero calibration.
Adjusting the glowplug voltage
A standard OS A3 glowplug, oder no. 1655, is employed, but the glow filament must be pulled
out by about 3-4 mm, using a pin or similar tool. For reliable ignition the filament should glow
bright red; if necessary, the glowplug voltage (default value = 2.1 V) can be adjusted in the
Limits menu.
This is the procedure for adjusting the glowplug voltage:
1. Select the "GlowPlug Power" parameter in the LIMITS menu (leaf through using the +/-
buttons).
2. Press and hold the "Change Value/Item" button -> the glowplug is switched on, and the edit
arrow appears before the voltage value on the screen. You can now adjust the glowplug
voltage using the +/- buttons (all the while holding the "Change Value/Item" button pressed
in). Adjust the glowplug voltage until the pulled-out filament glows bright red.
3. As soon as you release the "Change Value/Item" button again, the new value is stored, and
the glowplug is switched off.
