1 Product description
1.1 Proper usage
The IFA router (Internet remote display router) is a part of the Internet-based digital remote display for the
visualisation of a solar thermal system. The IFA router enables the display of temperature and performance
data of a solar thermal system in your Internet browser window*. In order to be able to display this data,
you will need a PC with Internet connection. For this purpose, the solar thermal controller (referred to
below as "controller") regularly transmits its measured values to the IFA router, which prepares the data
and forwards it to a server. The server archives the data and generates graphics for the Internet browser.
Password-protected server access secures this customer data against unauthorised access.
The current temperature readings of the selected solar energy system are visualised. In addition, the tem-
perature curves are shown in a temperature diagram. When using a heat meter, instantaneous power,
energy balances and CO
2
savings are also displayed.
The prerequisites for the Internet-based remote display are a suitable controller and an Internet connection
via a broadband router with modem** for the IFA router. The broadband router must have a free LAN port
and be continuously connected to the Internet. The controller and the broadband router with modem are
not included in the IFA router delivery package.
The IFA router can also send the graphics via the integrated WLAN to a WLAN-capable digital picture
frame.
* tested browsers: Microsoft Internet Explorer
®
6 and 7, Mozilla Firefox

** DSL, cable modem or another broadband connection. Analogue modems and ISDN are not supported.
1.2 Components
The remote display consists of the following components:
A suitable solar thermal controller (not included in the IFA router delivery package)
RS232 interface cable with 9-pin D-sub socket, 3-wire
RS232-USB converter with 9-pin D-sub connector, cable with USB connector
IFA router (ASUS WL-500g Premium V2 with special firmware for remote displays)
USB flash drive, with firmware for remote displays
Mains cable for connecting the IFA router to the LAN port of a broadband router
Broadband router with modem** with continuous Internet connection and a free LAN port (not
included in the IFA router delivery package)

1.2.1 ASUS router with firmware for remote displays
The most important component of the remote display is the ASUS WL-500gP V2 IFA router with a special
firmware for remote displays. Since the operating system and application software of the ASUS router have
been replaced by firmware, the original manual for the ASUS router is rendered invalid. The technical data
of the IFA router as well as the approvals and certifications of the IFA router remain valid.

1.3 Functionality
The controller cyclically sends the current system data to the IFA router, which forwards the data to a central
server. This server then displays the data in visualised form on the Internet. The data is embedded into the
appropriate system image in the IFA router and the temperature diagram is generated. The system image
and the temperature diagram are sent via the wireless LAN interface from the IFA router to a digital picture
frame.

To do so, the semicolon before the phrase "diagram_bitmask_override"
must be deleted and a sensor selection must be defined as shown in
the example. The selection is defined by six characters which are each
separated by a "|". The characters may only have the value "0" or "1"; "0"
means sensor "not selected", and 1 means sensor "selected".
In the example "0|0|1|1|1|1", the sensors T1 to T4 would be selected,
while T5 and T6 would be deactivated.
If you wish to return to the standard settings, you must re-write a semi-
colon in front of the phrase "diagram_bitmask_override".
8.3.4 CO2 factor
;1.4 Override CO2 factor
;factor_CO2 = 0.232
If you wish to use another factor than 0.232 Kg/kWh to calculate the
CO2 value, this factor can be defined.
To do so, the semicolon in front of the phrase "factor_CO2" must be
deleted and a factor defined as shown in the example. The physical unit
of the factor is kg/kWh.
If you wish to return to the standard settings, you must re-write a semi-
colon in front of the phrase "factor_CO2".
8.3.5 Diagram title
;1.5: Diagram title (50 characters)
diagram_title = ""
You can specify a title for the temperature diagram which is shown
above the temperature curves. The diagram title is limited to a maxi-
mum of 50 characters.
In the factory, the diagram_title is set to "", i.e. no title is defined.
The title is defined by entering characters within the quotations marks,
e.g. diagram_title = "My solar energy system"

8.3.6 Diagram legend
;1.6: Texts for diagram legend (12 characters)
diagram_t1_text = "T1"
diagram_t2_text = "T2"
diagram_t3_text = "T3"
diagram_t4_text = "T4"
diagram_t5_text = "T5"
diagram_t6_text = "T6"
Names can be defined for the temperature sensors for the legend in the
temperature diagram. The texts for the temperature sensors are each
restricted to a maximum of 12 characters.
The legend texts diagram_t1_text...diagram_t6_text are set in the fac-
tory to "T1"..."T6".
The names are defined by changing the characters within the quotation
marks, e.g. diagram_t1_text = "Collector"
8.3.7 Units for output/energy
;1.7: Units in system image ("kw" or "btu")
system_units = "kw"
The physical units for output and energy can be converted from metric
units to those units commonly used in North America.
In the factory, system_units is set to "kw", i.e. the units are shown in W
or Wh.
If system_units is set to "btu", the units are shown in Btu/h or Btu.
The unit prefixes, e.g. "k" (kilo), "M" (Mega) etc. are given automatically.
8.3.8 WLAN after turning on the IFA router
;2.1: Disable wireless LAN after power on (yes: 1 / no: 0)
wlan_disabled = 0
Wlan_disabled is preset to 0, so the wireless LAN is automatically ena-
bled after restarting the IFA router.
If wlan_disabled is set to 1, the wireless LAN of the IFA router is inactive
after restarting.
8.3.9 Wireless LAN name
;2.2: Wireless LAN name
ssid = "TK RW1 Net"
The ssid is preset to "TK RW2 Net", so the wireless network of
the IFA router appears on the picture frame under the name
"TK RW2 Net". A change of name requires a new assignment of the net-
work in the digital picture frame.
NOTE
The name must always be given in quotation marks, e.g. "My solar
energy system".

8.3.10 Wireless LAN channel
;2.3: Wireless LAN channel (value between 1 and 11)
channel = 6
The factory preset value for channel is set to 6. The value can be changed
between 1 and 11.
8.3.11 Wireless LAN encryption
By default, the IFA router is supplied without wireless LAN encryption
because no security-relevant information is being transmitted. If desired,
the network can be encrypted with WEP, WPA or WPA2.
To do this, the configuration file "Config.wri" on the USB flash drive
needs to be modified (see section 8.1 "Appendix: configuration file").
The settings for the wireless LAN encryption are made in "Config.wri",
under "Wireless LAN encryption". If a wireless LAN encryption is selected,
a password of your choice must be set under "Wireless LAN password".
This password is required for access authorisation for the digital picture
frame.
NOTE
Config.wri may only be opened with Microsoft® WordPad!
;2.4: WLAN encryption ("OPEN", "WEP", "WPA", "WPA2")
encryption = "OPEN"
Factory preset value for encryption is "OPEN", so the network is not
encrypted.
If the network is to be encrypted, you must set
encryption = "WEP" for WEP encryption,
encryption = "WPA" for WPA encryption,
encryption = "WPA2" for WPA2 encryption.
8.3.12 Wireless LAN password
;2.5: Wireless LAN password (OPEN: "", WEP: 5 or 13 characters,
WPA / WPA2: 8 to 63 characters)
passphrase = ""
The factory preset value for the password is " " because the network is
unencrypted by default.
If you chose WEP encryption, the password must be entered as a 5-digit
or 13-digit password, for example
password = "12345"
If you chose WPA or WPA2 encryption, the password must be entered as
an 8 to 63-digit password, for example
password = "12345678"
NOTE
Only use numbers and letters for the password. A distinction is made
between uppercase and lowercase letters.
