1. Safety
IMPORTANT NOTE:
Some software versions have alterations in the file structure for parameter settings.
This was necessary to add new parameters.
New software versions are always capable of reading and interpreting older files of settings.
Older software versions can not read and interprete new files of settings.
Thus any downgrade (loading an older software than the currently loaded one) should be avoided
because it might lead to loss of settings.
Connection to the internet
The WIB8000 (Web Interface Board) may not be connected directly to the internet, but must be protected by
a firewall or a VPN tunnel.
So choose an IP address for the WIB from the private address ranges according to RFC 1918.
10.0.0.0 - 10.255.255.255
172.16.0.0 - 172.31.255.255
192.168.0.0 - 192.168.255.255
Find details for the IP address setting on page 15.
Settings
A password with administrator authorization for the first access is printed on the adhesive label.
Find details for the password setting on page 27.
NOTICE
All three passwords must be modified by the administrator during start-up (possibly
specifically for each WIB module) !
ESD NOTE
Notice the country specific ESD standards when opening the unit.

2. Operation modes
up to 32 Stulz units:
PC with web
browser
Intranet (LAN)
or
Provider // Internet (WAN)
Furthermore necessary for the start-up:
1. PC or notebook with network connection
3. Web browser as e.g.
- Internet Explorer from version 9
- Mozilla Firefox from version 2
- Opera from version 9
- Safari from version 3
up to 32 Stulz units:
Following protocols are supported:
- SNMPv1/v2c (Simple Network Management Proto-
col, Version 1, Version 2c), IPv4
Port 161
- HTTP (Hyper Text Transfer Protocol), IPv4
Port 80
The WIB exists, as far as the hardware is concerned, in
two versions:
1. installed in the electrical box of an A/C unit, where it
is supplied by the 24 VAC voltage already present in
the A/C unit.
2. installed in a separate box with individual power
supply.
The WIB (Web Interface Board) is an interface between STULZ air conditioning units and the intranet or inter-
net via an ethernet connection.
This connection allows monitoring and control of A/C units. On the operators’s side the appropriate hardware
(PC or server) and the appropriate software (SNMP client and/or web browser) are necessary.
The STULZ controllers in A/C units are sequentially scanned on occurred alarms and availability. In case a
controller detects an error or a controller is not available (power failure at the A/C unit), the webside displays
this error, an alarm email is sent and a SNMP trap message is sent to each of the max. 6 configurable SNMP
trap receivers.
The corresponding Stulz controller provides a read out of all operating data simultaneously with the network
request (SNMP GET function or opening of a website).
In case values are changed via the website or the SNMP client, these values are immediately transferred to the
corresponding controller.
Every single user can individually choose between the temperature display in °C or °F as well as among diffe-
rent user languages when the data is displayed on the website (http). For website display it is not necessary to
allow Javascript or cookies. The individual user settings (temperature, language) are saved simply by creating
a bookmark in the browser.
It is also possible to assign a sequencing function via the Stulz bus; i.e. the controller receives on/-off com-
mands via the Stulz bus. The sequencing function includes an alarm monitoring and an A/C unit start when
limit values are exceeded.
In addition to this you should have your system administrator
provide you with all necessary data for the start-up. In appen-
dix A6 there is a form which you should have filled in forthis
purpose.

The STULZ bus is a RS485 bus where up to 32 STULZ controllers can be connected with a WIB. The Stulz
bus is an RS485 bus with fixed transmission parameters such as baud rate 9600 Baud, 8 data bits etc.
Following values are valid for the RS485 bus:
Differential signal is transmitted via HIGH/LOW connection
Maximum length: ca. 1000m (3300 feet)
Maximal bus participant distance: ca. 35m (114 feet)
Maximal bus participant number: 32
Connection: 2 pole shielded data line, twisted in pairs with an impedance of 120 Ω
Controllers wired in series, not in star
Data bus termination resistor (R: 120 Ω) at the beginning and end of bus
The WIB has its own integrated termination resistor (R). This resistor must be activated by setting the switches
S1 - S4, when the WIB is at the beginning or end of the Stulz bus.
The Stulz bus is a two wire connection with a screen which must be twisted in pairs. The screen must only be

connected on one side of the cable to the provided terminals. Connecting the screen at both sides will lead to
problems with different potentials.
All types of STULZ controllers can be connected in the STULZ bus.
- Controllers of type C5000 must be equipped with a MAXBoard.
- C4000 controller must be of the C4000max version.
To save the battery for the real time clock, the battery is not connected at the delivery. The connection is done
by the jumper J1. See detailed description in appendix A2.
4.3 Adjustments to build up the STULZ bus
All units need their own CPU address/global address (C7000), without any duplicates, so that they can com-
municate in the bus line (Exception C6000 Supervisor/Controller). They are configured for each controller
type as follows:
In case of a controller/supervisor combination the following must be observed:
Both controllers can be queried separately. Since both controllers have their own sensors they receive the
corresponding actual values from both sensors. When the supervisor does not control you won’t receive any
alarms when querying the supervisor.
currently active controller responds. You will always receive all alarms and the correct status of the
components.
After all controllers have received an address and the protocol and gateway addresses have been assigned,
the WIB8000 board must be configured.
This tells the board, which controller can currently be accessed.
The WIB8000 board has an automatic Stulz bus unit recognition system.
With this function all connected Stulz units are automatically recognized and the configuration is registered.
The function is called up by the HTTP interface (browser) in the menu "Web interface/bus", paragraph "scan",
menu item "start" by pressing the "Send" button.

5. Configuration
A password with administrator authorization for the first access is printed on the adhesive label.
After you have entered the password and confirmed it by Enter/Return the authorization is shown for a short
time.
Special case: Chiller with C6000
To get a write access for a chiller (CSO, CLO, CSI, CPI), equipped with a C6000 controller, introduce the password of the C6000 con-
trol level in the menu Config/Web Interface.
You installed the Stulz bus by connecting the controllers by means of bus lines and setting the global address-
es. You also linked the WIB8000 module in the Stulz bus and supplied it with power.
Before you connect the WIB8000 with the customer network, it is necessary to adjust the network parame-
ters which are provided by the customer. For this connect the WIB8000 to your PC/laptop first and configure
the WIB. The adjusted parameters are updated after a WIB8000 reboot.
To connect the WIB8000 to your PC/laptop the following network parameters are adjusted as default
settings:
DHCP: off
IP address: 192.168.50.52
Subnet mask: 255.255.255.0
Important: If the settings which are desired by the customer differ from the settings above, you can not reach
the WIB8000 anymore by your PC/laptop after a reboot. It has now been set up for the customer network.
Now you can switch on the PC, which also provides a network connection, start the internet browser and call
the html pages stored in the WIB module by typing the address http://192.168.50.52 into the command line.
Via the html pages you can configure the WIB module.
First you are asked to enter the password. Three passwords for different authorizations exist:
1. ............... (highest authorization, administrator)
2. ............... (medium authorization, read and write, only levels "Info" and "Operate")
3. ............... (lowest authorization, read only, only levels "Info" and "Operate")

5.1 Settings for the service technician
The internal clocks of all units, which are connected to the WIB8000 by the Stulz bus can be synchronized.
In case of an indirect connection (e.g. connection of a C7000AT to a C7000IOC by the IO bus) the C7000AT
system clock is not synchronized.
The synchronization of the system clocks of all connected units enables the comprehension of the chronolog-
ical context of the unit/controller eventlogs and simplifies the elimination of complex error causes.
The WIB can update its own system clock by sending requests to a NTP server (SNTP - Simple Network Time
Protocol).
The synchronization of the connected controllers as the update of the WIB system clock by SNTP request
via network, is done at once after the activation of the corresponding function and then with the cycle of the
adjusted interval.
The following parameters have to be adjusted. A valid NTP server address (server name or IP address), two
time intervals (hourly/daily/weekly) and the relative time difference of the local time to UTC time.
CET
CEST
Sydney
Canada -3:30
USA, Frederick -5:00
On one hand a time interval can be adjusted, in which the
WIB updates its system clock, on the other hand you can
adjust a time interval, in which the WIB synchronizes the
system clocks of all connected controllers with the WIB
clock.
The UTC time is also called "coordinated universal time"
and is edited by the NTP server.
Examples:
First you should set the local time. This can be done in the menu "time". The settings done are transmitted to
the system and will then be effective by clicking on the "Send" button. Clicking on the "Reset" button resets
the parameters to the default settings. This is also valid for all following menus.
Before setting the time you should connect the battery on the board (see A2. RTC battery change). Other-
wise your settings will get lost with a power failure.

The entries for the following three menu windows are defined by the
network administrator. In the appendix a form is printed which must
be sent to the network administrator before the WIB system start-up
so that this data is available for start-up.
Settings for the network (Menu: Web Interface/Network/Setup)
All network modifications are effective only after a reboot of the WIB. You can comfortably reboot the WIB by
clicking on the menu item "reboot" in the menu "WEB INTERFACE".
The indication of a DNS address (only IP address possible) is compelling, if server names for other servers
(mail, NTP, SNMP Trap) shall be entered instead of their IP addresses.
The http port can be individually set. At the delivery the standard http port 80 is used.

Settings for sending an e-Mail (Menu: Web Interface/network/email)
Fill in the choice boxes according to the information given in the network check list in the appendix A6. item 3.
By the setting "date in smtp header" a date field (date / time of the email creation) which is required according
to newer email specifications, can be inserted in the header of each email.
Tests have proved, that there are email systems, which accept messages without this field, but which on the
other side, reject messages which do have this field containing a not plausible date.
For this reason this function should only be enabled, if you can ensure that the internal clock of the WIB8000
is correctly set and the WIB8000 battery is sufficiently charged to bridge over a power failure.
Alternatively, the SNTP (Simple Network Time Protocol) synchronization of the internal clock of the WIB8000
can be enabled. Then, even with a faulty battery and after a power failure, the internal clock of the WIB is
synchronized over the network. The correct setting of the WIB's internal clock is always ensured when using
SNTP.

the designation is automatically generated following the pattern "bus x, unit y".
x = bus number of the WIB8000
y = global address of the unit, which caused the alarm (trap).

non-ASCII characters, make sure that, enabling the trap unit name option "extended", all trap receivers, which
receive messages from the WIB8000, support UTF8 encoded trap value fields. Otherwise, there will be dis-
play problems at the SNMP client.

Up to six traps can be configured, for each of which the community, the receiver the output port and the ver-
sion must be adjusted. Concerning the version you can choose among three options:
- v1: Trap messages are sent to this receiver in the SNMP format 1.
- v2c: Trap messages are sent to this receiver in the SNMP format 2c.
- both (default): The receiver gets each trap message in format 1 and in format 2c.
(two messages for one event in total.)

wib8000 original instructions
The bus will be configured automatically, when you initiate the WIB module to scan the bus and to record all
units found in the bus configuration.
Section: Scan
For this purpose select for one or the two busses the menu item "Start" of the "scan" function and click on the
"Send"-Button. The number of units found is updated each time when a unit has been found.
You can abort the scan at any time, when e.g. the actual number of existing units in the bus appears in the
choice box "number of units", by selecting the menu item "Stop" and clicking again on the "Send"-Button.
You can limit the global address range which is scanned to save time. Scanning 1200 addresses takes
approximately one hour.
Section: bus 1 / bus 2
To indicate the bus you can give it a name, which refers for example to the location where the units are placed.
In "Timeout" you can set the time how long the WIB waits for a response of connected units. Exceeding this
time is evaluated as a communication error. The maximum cache holding time indicates how long data points
are available in the cache memory as valid data points.
A short cache holding time guarantees actual data but causes high data traffic on the bus. A longer cache
holding time reduces the traffic but bears the risk that the data might not be up to date.
With the pre-fetch period you can set a time interval, in which the WIB reads and buffers all data points that
are configured for each single unit for the unit overview (menu: config/web interface). Data points which are
cached in this way, are read from the WIB cache, instead of being directly read from the unit during http/
SNMP queries to the WIB. The setting "0" switches the pre-fetching off.
With a properly tuned pre-fetch period the (up to 20) data points per unit will be provided faster at the http and
SNMP interface.
For this purpose the pre-fetch period must be set so that all data points can be read before the maximum
Bus configuration (Menu: Web Interface/Bus/Setup)
20 EN/11.2018/G67C © STULZ GmbH – all rights reserved
wib8000 original instructions
The names of the units found are generated automatically by adding the bus number to the expression "Unit"
in the adjusted standard language and after the insertion of a hyphen the global address of the unit. For
C7000 IO controllers the unit name saved in the controller, if it is not the default setting "unit name", will be
taken.
So the unit names are displayed in the bus and zone view as represented below.
This name can be modified in the menu "Config/Web interface" for each unit.
Manual configuration of units within the bus configuration
Under certain circumstances an automatic unit detection by
the "scan" function in the bus menu is not possible. This is the
case if a unit/controller can not be provided with voltage at
the time.
By menu item "create unit" in the menu "Web Interface/bus"
you have the possibility to manually create units.
By menu item "delete unit" in the same menu you can remove
a unit from the bus configuration, without cutting the bus
wiring. Such could be the case if you want to operate the
A/C unit temporarily as an individual A/C unit e.g. for test
purposes.
Up to 20 freely selectable parameters can be displayed for each unit in the bus or zone overview. These
parameters can be defined in the menu "config/web interface". The size of the unit blocks conforms to the
largest block in a line.
cache holding period has expired. Taking into account the bus performance (number of units, connection type
Ebus via C7000AT, response times of units), the pre-fetch period may not be set too small, because otherwise
the bus queue will be overloaded. In this case not all data points can be read.
