MicroGuard-USB Instructions: GSM Remote for Parking Heaters
1. Introduction
The purpose of this manual is to provide general instructions for installation
of our MicroGuard-USB devices into cars equipped with parking heaters
and to explain parameter settings necessary for operation with different
heater manufacturers and models. Dedicated manuals for different heaters
are available in German language on our website:
http://microguard.de/downloads/anleitungen-microguard-usb
Please use those manuals for the individual connection of our device to a
particular heater model.
2. Scope of delivery
In the delivery you will find the following content:
•MicroGuard-USB (control device),
- special version with power conversion module +12V or
- a special version with modification for your specific connection
•Connectors with 15cm cable (will need individual extension)
•Option: external temperature sensor(s), if ordered
•Option: y-cable for several temperature sensors (if ordered)
For GSM remotes we offer only external temperature sensors.
3. General switching function
MicroGuard-USB is equipped with two output and two input lines which can
be used for heater switching and switch control (or alarm lines).
•Older heaters can be controlled using +12V signals (orange
output) or ground output (brown).
•Newer heaters use Bus signals (W-Bus, LIN, CAN). We offer a
special modul equipped with W-BUS signals. In other cases we
adopt the connection of our module to an existing control device
(like timer or wireless receiver).

7. General Initializing Procedure
MicroGuard-USB uses entries in the phone book of the SIM card to store
system parameters during initialization and later during operation. The
general init procedure is identical for all the modules, independently of the
connection type. Some parameters have to be adopted to the individual
heater / control device after initialization. Please refer to the chapters in the
German manuals for details.
Please go through these steps to initilize the system:
1. Validate that you can call out and send SMS using the SIM card.
Give yourself a call and send SMS to your phone number using
another mobile phone.
2. In the security options delete the need to enter a PIN when
starting the mobile phone. Validate this setting by switching the
mobile off an on again.
3. Delete all call forwarding using the GSM code ##002# with your
mobile.
4. Connect MicroGuard-USB with power supply. LED starts to flash
1x a second.

5. Insert SIM into the USB UMTS-Stick and connect the stick to
MicroGuard-USB (PORT1!). After 20-30 seconds LED signal
changes and shows 2x fast flashing every second.
6. Make a call to the SIM in the stick using your mobile phone. This
mobile will be registered in the system as master control number.
The call will be terminated after 1-2 “rings”.
7. After call termination LED flashing changes to 3x long on, some
seconds off, 4x long on. In this time the parameters are being
written into the phone book of the SIM.
8. After approx. one minute, LED starts to flash 3x very quickly. If
you ordered a temperature sensor, plug in the sensor into the
Mini-USB port during this flashing procedure. Temperature
sensors have a unique ID which has to be registered in the
system during init procedure.
9. Sensor registration takes approx. 30 second. After that a call is
executed to the master control number (your mobile). Also,
confirmation SMS “System Init OK” is sent to the master number.
General Initialization completed.
Now it is time to adjust some system parameters to your heater or control
device connection. Below we describe parameter settings only for +12V
and GND controlled heaters. Other special settings might be required for
other connection types, please refer to German manuals or contact our
support: [email protected]
10.1 Parameters for heaters controlled by +12V
The duration of the +12V signal on the orange output (heating time) is
controlled by the parameter ORPULS. To be able to switch the orange line
by a simple call, please send an SMS with the content
SW=19 ORPULS=xxxx
from the master control number to MicroGuard-USB. Note that xxxx
determines the heater time in minutes (first two numbers), e.g:
Seite 8 Überwachung | Benachrichtigung | Steuerung per Handy

MicroGuard-USB Instructions: GSM Remote for Parking Heaters
•Heating time of 30 minutes:
SMS command „SW=19 ORPULS=3000“
•Heating time of 15 minutes:
SMS command „SW=19 ORPULS=1500“
Test the switching function. You can check the parameters using SMS
command MGCONFIG.
10.2 Parameters for heaters controlled by Ground signal
The duration of the GND signal on the brown output (heating time) is
controlled by the parameter BRPULS. To be able to switch the brown line
by a simple call, please send an SMS with the content
SW=09 BRPULS=xxxx
from the master control number to MicroGuard-USB. Note that xxxx
determines the heater time in minutes (first two numbers), e.g:
•Heating time of 30 minutes:
SMS command „SW=09 BRPULS=3000“
•Heating time of 15 minutes:
SMS command „SW=09 BRPULS=1500“
Test the switching function. You can check the parameters using SMS
command MGCONFIG.
Note: To switch on both lines at the same time use SMS command
SW=29

8. External Switch Button
* ab Software-Version 1.43
MicroGuard-USB allows to cinfigure an exterlan button which can
switch the heater on and off when installed in the car. ig. 4
Shows a push button with integrated ON-indicator driven by the
signal on the orange output line. Note that the LED has to come
with a series resistor to be able to withstand +12V at the orange
line. Any other button without LED indicator can also be used
instead.
To be able to use the button function, some parameters must be
modified vs. factory settings, see Table below:

9. Active Feedback of Switching*
* Software-Version 1.43 (2015) and later
MicroGuard-USB indicates the switching event by termination of the
incoming call. The number of “ring” signals is an indicator for the switchong
operation:
•Switching ON: 2 rings
•Switching O : 1 ring
MicroGuard-USB allows an active feedback about the switching operation
using available alarm lines. The feedback type can be set to call or/and SMS.

MicroGuard-USB Instructions: GSM Remote for Parking Heaters
11.1 Vehicle localization
The GPS receiver at PORT2 delivers current location of the vehicle every
10 seconds. This position can be requested any time using SMS
POSITION
MicroGuard-USB replies with the current location, e.g.:
https://www.google.de/maps/place/51.0754950,13.7478625
11.2 24h Timer
Beyond vehicle localization a GPS receiver delivers also a very accurate
satellite timer which can be used for timer functions. We have implemented
a 24h timer which allows to define the switching time of the heater to be set
in advance within 24h. You can send one SMS to the heater in the evening
to define when the heater will be switched on next morning (1 time only).
The SMS command is compatible with Eberspächer App EasyStart GSM
STARTxxyy
where xx is start time in hours and yy start time in minutes.
Example:
START0745
will start the heater next morning at 7:45 am.
11.3 Geo-Fencing
This feature generates a notification based on the last saved
position and the fact that the vehicle leaves the region of 300m
around this location. The notification can be defined to be a phone
call or text message with a text which can be individually set by
the user. This feature is being frequently used as theft alerts for
vehicles.
A summary of SMS commands for Geo- encing is given in Table
below.
http://www.microguard.de V1.0 Seite 15

GEOOFF Switches off GEO-fencing without changing the position
SETGEOSMS=<Text> Sets <Text> as content of the text message for GEO-fencing,
At the same time alert type is set to text message.
11.4 GP -Home
GPS-Home is the inverse function to GEO- encing. When the
vehicle enters a region 300m around a predefined location, an
alert is being generated. Also here the notification can be defined
to be a phone call or text message with a text which can be
individually set by the user.

12 Additional remarks
12.1 witching modes
•Using one of the connection schemes shown above heaters can
be switched on and off.
•Heating time is determined by the setting in MicroGuard-USB
(parameters ORPULS and BRPULS). A subsequent call/SMS
switched the heater on again.
•Another control device may be used without restrictions.
However, control devices will influence themselves. It is
recommended to use the same device fro switch off as for switch
on.
12.2 Using of mobile phones instead of U B ticks
Theoretically, a usage of compatible mobile phones instead of sticks is
possible. Due to the weakness of charging for STD mobile batteries,
reliable functions with mobile phone connected to MicroGuard-USB cannot
be guarneed at lower temperatures (below 5°C).
Please use USB Surf Sticks ONLY!
