CONTROL BOXES LANDIS & STAEFA LGB21/LGB22 – LMG21/LMG22
The Landis control box starts the fan and begins the pre-purging of the combustion chamber. The air pressure switch controls the
correct operation. At the end of the pre-purging phase, the ignition transformer cuts-in followed by the opening of the gas valves.
In case of missed ignition or accidental shutdown, the ionisation probe cuts-in and set the burner in lockout mode within the safety
time.
ONLY FOR LMG21 / LMG22 CONTROL BOXES
In case of burner lockout, it is possible to read which cause originated it. Proceed as follows: with the burner in lockout mode (red
LED switched on) keep pressed the lockout button for more than 3 sec. then release it. The red LED will blink according to the
following error code list:
Error Code
2 blinks
3 blinks
4 blinks
7 blinks
8÷17 blinks
18 blinks
19 blinks
20 blinks
During the error diagnostic phase, the output controls are disabled and the burner keeps on staying in lockout mode.
- Exception: the fault alarm on "AL" terminal: the burner will be switched on only after a Reset is made. To reset the control
box press the lockout-reset button for 0.5 to 3 seconds.

SATRONIC DMG 972 CONTROL INFORMATION SYSTEM
The SATRONIC DMG 972 control is a micro-processor control which provides information about the current opera-
tion of the burner and the cause of any faults. The information is available by reading the "flash code" at the red LED
within the lockout reset button as detailed below. By the use of additional monitoring equipment a short history of
recorded faults is also available. There are two types of additional monitoring devices available from Satronic Ltd. The
"satropen" is a small pocket reader designed to give a visual read out of status, flame current and supply voltage.
Computer software is available to allow access to the current information and stored data.
On burner failure the red LED is permanently illuminated for a period of approximately 10 seconds, followed by a
brief "dark phase", then one of the following flash codes will indicate the cause of the fault. This indication will repeate
as long as the lockout reset button is not reset.
