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.

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 factory 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 network 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.

8.3.13 Protocol for IP
;3.1: Protocol used for IP issue ("static" / "dhcp")
wan_protocol = "dhcp"
The protocol is pre-set in the factory to "dhcp". If a fixed IP address is
used, the wan_protocol must be set to "static". Then, the IP address
must be defined as shown in 8.3.14…8.3.16.
8.3.14 IP address
;3.2: Only if 3.1 "static": Declaration of IP address
wan_ip_addr = ""
If the protocol for the IP issue, as described in 8.3.13, has been set to
"static", the IP address must be defined within the quotation marks,
e.g. wan_ip_addr = "92.168.1.5".
8.3.15 Subnet mask
;3.3: Only if 3.1 "static": Declaration of subnet mask
wan_netmask = ""
If the protocol for the IP issue, as described in 8.3.13, has been set to
"static", the subnet mask must be defined within the quotation marks,
e.g. wan_netmask = "255.255.255.0".
8.3.16 Gateway
;3.4: Only if 3.1 "static": Declaration of gateway address
wan_gateway = ""
If the protocol for the IP issue, as described in 8.3.13, has been set
to "static", the gateway must be defined within the quotation marks,
e.g. wan_gateway = "92.168.1.1".
8.4 Restoring the configuration file
For safety purposes, a copy of the configuration file "Config.wri.
backup" is saved in the "Config" directory. If problems occur after
editing the configuration file "Config.wri", delete the file "Config.wri"
from the config directory and rename the "Config.wri.backup" file to
"Config.wri".

11 Error search
The IFA router is a quality product and is designed for many years of continuous use. Should, however, a
fault occur, the cause of the fault is often not the IFA router itself but the peripheral system components.
The following description of some causes of problems should help the installer and operator to isolate the
problem so that the system can be repaired as quickly as possible and to avoid unnecessary costs. Of course,
not all possible problems can be listed here. Here you will find the most common causes of problems that
cover the majority of possible faults. Only return the IFA router when you are absolutely sure that none of
the problems listed below is responsible for the fault.
11.1 General error sources with the IFA router
Problem Cause / Remedy
The time display in the system image
is not updated or the message "Note:
the IFA router is waiting for data from
the solar controller. Please check the
cable connection between the solar
controller and the IFA router should
there be no graphic display shown
within 90 seconds!" is displayed.
Interruption of the serial connection between the controller
and the IFA router. Please check the cable connection!
Try resetting with the restore button.
Message "Fault: No or wrong USB flash
drive inserted!".
You may only use the supplied USB flash drive. After inserting
the correct USB flash drive while the device is still switched
on, you may have to do a "Reset".
Message "Fault: No USB-RS232
adapter found".
Please verify that the USB serial adapter is plugged into the
IFA router! After installing the adapter, you may need to do
a "Reset".
Message "Fault: Incorrect software
version. Please contact your specialist
dealer".
The controller is sending data that is incompatible with the
router version.
Contact your distributor and state the two 3-digit identification numbers S: and A: (
1.2.3
4.5.6
xxxxxxxxxxxxxxxxxxxxx
) on your USB flash drive
and the specific firmware of the solar thermal controller
(displayed in Off mode, see the solar controller operating
instructions).
The logo is not displayed. The logo must have the name "logo.jpg" and must be created
in the JPEG format. It must be located on the USB flash drive
in the "share\Logo" directory. By default, no logo is displayed!
"Note: Maintenance work on the
router… please wait" or "Note: File
system check... please wait".
The IFA router is independently conducting cleaning/maintenance work! This message usually appears daily between
00:00 and 00:15 a.m., and automatically disappears again.
On no account should you pull the plug! If the message
appears outside of this time period, an error has occurred. If
this is the case, re-start the device!

11.2 Error causes with the picture frame
Problem Cause / Remedy
Wireless network not found. • Is the IFA router in operation?
• Is the maximum distance to the IFA router being exceeded?
The "SolarShare" network computer
cannot be found.
Can occur if you try to reconnect an existing connection.
1. Restart the IFA router and wait until the power LED is lit.
2. Switch on the picture frame and restart the network if
necessary.
The wireless LAN connection is very
slow, even though the picture frame is
located within range of the WLAN.
The selected wireless LAN channel is already used by other
devices. The wireless LAN channel can be changed with the
USB flash drive of the router (see Chapter 8, "Changing the
wireless LAN settings").
When setting the wireless LAN connection, the warning message appears
that the connection is not secured.
By default, the wireless LAN connection is not encrypted. This
allows all persons who are within range of the wireless LAN
network to log into the IFA router and look at the pictures.
In order to avoid this, the encryption can be activated (see
Chapter 8 "Changing the WLAN settings").
11.3 Causes of faults in the IFA router
Problem Cause / Remedy
The time in the system image and the
diagram remains the same! The starting image "Remote display account
successfully activated!" is shown, even
though the remote display has been
put into operation.
Check the Internet connection.
If the IFA router is being operated behind a firewall, ensure
that the port 5204 has been released for outgoing connections! Operation via a proxy server is currently not possible!
Check whether the serial connection between the controller
and the router is functional.
