Modem (2) is connected according to diagram on Figure 15. Power supply cable’s white wire is
connected to motors wire (pin X2-8) and brown to X2-4. Adapter EP0005 cable is connected to modem
and to controllers UART connector. Depending on the location of the modem, extension cables may be
used.
Before inserting the SIM card to modem (Figure 16) following actions have to be done:
1.
SIM card has to be activated by the mobile operator.
2.
SIM card PIN code reguest must be turned off.
3.
Check with mobile phone that it is possible to send SMS with this SIM card.
4.
In SIM card´s phonebook must be only the numbers, where the error messages from the burner
will be sent to.

Flue gas fan
3.2
Usage of flue gas fan improves work of heating system and optimises burning procedure. In order to
activate flue gas fan speed control, PAR30 has to be set to value “1”. In this case flue gas fan control is
proceed by controllers internal air-table, where for every power level certain amount of combustion air
is prescribed according to PAR31…PAR36. If select PAR30 “2” , the flue gas fan is switched off. Value “3”
and “4” are not applicable in this burner. Value “5” in PAR30 allows controlling fan’s speed with under-
pressure sensor what is installed to boiler or burner. Flue gas fan follows pre-set underpressure or draft
by PAR61. Control starts when pressure gets lower or rises over value set in PAR61. Product code for
compact under-pressure sensor is AP0003A. AP0003A sensor is connected to TEMP2 socket. Before
implementation the underpressure sensor has to be calibrated. To do that go to INFO menu and check
value of ΔP. It has to be close to “0” (-0,3…+0,3). If not go to PAR63 and by changing its value try to get
ΔP close to “0”.
To insert the SIM card modem has to be switched off from
supply mains. To insert the card push it into modem’s slot
as long as click is heard. To remove card it has to be
pushed as long as spring pushes card out.
To activate sending messages the PAR52 value has to be
changed from 0 to number of phones the error message
will be sent. 0 means that no messages will be sent. 2
means that message will be sent to 2 first numbers in SIM
card.
Modem has 2 indicators. Green one shows that modem is
switched on. Red one shows status of modem.
Description of modem’s statuses is described in Table 4.
