BUS TERMINATING RESISTORS / ADDRESSING
The installation instructions described how to install and
wire up the individual basic/controller modules and their
expansions.
The commissioning instructions now explain what steps
are necessary for successful commissioning. The com-
missioning instructions refer to the commissioning assis-
tant that runs automatically on the TopTronic®E when it
is started up for the rst time and guides you through the
complete commissioning.
Before switching on and starting the commissioning as-
sistant, check the following points and make any neces-
sary settings:
• Set the bus terminating resistors
• Set the addresses for all modules with DIP switches
(Setting the addresses of the control modules is only
possible after switching on)
The commissioning assistant sets the addresses of the
control modules and congures the entire plant.
1. Bus terminating resistors
The bus terminating resistors must be activated on the
devices that are furthest apart from one another.
It is best to activate the terminating resistor on
the heat generator and on each bus station
(usually room control module) that is installed
furthest away from it.

If the components of the bus system are
exclusively tted in the heat generator, there
is no need to activate the bus terminating
resistors!
2. Setting the addresses for the basic/
controller modules (DIP switches)
The addresses of the individual modules are set using
the DIP switches on the circuit boards. Each module must
have a different address. The addresses do not neces-
sarily have to be set in consecutive sequence.

The factory settings for the modules were se
-
lected so that there is no need to change the
address settings, as long as no module oc
-
curs twice in the bus system!

If there are several controller modules of the same type
in the bus system, the modules must have different ad-
dresses set for them. Use the available vacant addresses
for this!
Setting the addresses of the control modules is only pos-
sible after switching on and it determines the allocation
to the heat generators, heating and DHW circuits, etc. in
the system.

COMMISSIONING ASSISTANT
3. Commissioning assistant
The commissioning assistant guides you through the indi-
vidual steps for conguring a simple heating system cor-
rectly in the shortest possible time.
The following points must be carried out one after the
other:
1. Conguration of the bus system
2. Setting the parameters of the individual devices on
the bus system
3. General settings (time, etc.)
4. Conguration of the (room) control module
If a more complex plant is involved, it will be necessary to
make additional settings in the Service menu. Refer to the
instructions for customer service technicians for this purpose!
Commissioning must always be started on the
control module tted in the heat generator!
3.1 Configuration of the bus system
The commissioning assistant appears automatically after
the rst startup, or can be started manually from the main
menu.
Fig. 07
Fig. 08
It is essential for the “Plant conguration” to be carried out
as a rst step. Only after that is the “Room control module
conguration” started on each (room) control module.
Fig. 09
After that, enter the code of the particular user level (in
case of questions, please contact Hoval customer ser-
vice).
Fig. 10
3.1.1 Setting the address of control modules
The addresses of the control modules has been set so
that their function is dened right away when the address
is entered on the control module.
Fig. 11
For example: control module is allocated to the basic
module heat generator with address 1
The control module can also optionally be allocated to
the controller modules PS and SOL. Refer to the ad-
dressing table (Fig. 06) and the allocation table (Fig. 12)
for this.

After the address of the control module has been set on
the heat generator, all devices are displayed on the bus
system.
Other (room) control modules on the bus sys
-
tem are only detected after they have been
congured.

COMMISSIONING ASSISTANT
3.1.2 Devices on the bus
Fig. 13
If installed basic/controller modules are not displayed,
please check the following things:
- Address setting of all connected basic/controller
modules (DIP switches)
- Wiring of the components (wiring diagram and con-
nection diagram)
- Setting the terminating resistors (instructions for
customer service technicians)
- CAUTION: Module expansions are not connected
to the Hoval CAN bus, and are thus not displayed
here
If all basic/controller modules are available on the bus
system, they will be congured in the next step.
The hydraulic and function application is set on each
module for this purpose.

COMMISSIONING ASSISTANT
The most important hydraulic applications in the control-
ler modules PS and SOL can be found in the correspond-
ing commissioning instructions.
Explanation of the function application: nor
-
mally, there is no need to make settings for
the function applications because in most
cases the correct function application will be
preselected when the hydraulic application is
selected. In various cases, adjusting the func
-
tion application allows ne-tuning or deactiva
-
tion of a function (see chapter 3.1.5).
For detailed information about all other parameters, re-
fer to the corresponding instructions for customer service
technicians.

* Module expansions (TTE-FE) are required for each of
these hydraulic applications!
See the instructions for customer service technicians for
information about additional hydraulic functions.
Please note that a suitable module expansion
is required in many hydraulic applications.
If no suitable hydraulic application is available, a simi-
lar hydraulic function must be selected and adapted by
means of the function application.

3.2 Setting the parameters of the individual
devices on the bus system
After the basic settings of all functions under “General”,
the most important parameters are listed in the other
function groups (“heat generator”, “heating circuits”, “hot
water”, etc.) (1, Fig. 18). The parameters are divided into
the corresponding function group and function with the
specication on which module (address) the function is
located (see 2, Fig. 18).
Fig. 18
Using “Edit” (3, Fig. 18) it is possible to carry out the most
important specic parameter settings (see example Fig.
19).
Fig. 19
The parameter settings for the function groups of “heating
circuits” (Fig. 20) and “hot water” (Fig. 21) can be made in
the same way as for the heat generator.
Fig. 20

Fig. 21
Information about the parameters of the controller mod-
ules SOL, PS, etc. can be found in the corresponding
commissioning instructions.
3.3 General settings
As the next step, settings must be made in the system
(sample screen Fig. 22). In most cases, it is sufcient to
check the suggested setting values!
Fig. 22
Depending on the individual requirement, one of ve start
screen types can be set during commissioning. More in-
formation about this can be found in the “Optional start
screen” chapter in the TopTronic E comfort operating in-
structions.

NOTES ON ELECTRICAL CONNECTION
6. Notes on electrical connection
WARNING
Make sure that no cables are live before
starting wiring work.
The mains voltage connections on the left
side and the entire lower connector strip car-
ries or might be carrying 230 volts. These ter-
minals are not allowed to be touched when
live: potentially fatal electric shock hazard.
Bus connections and sensor lines must be in
-
stalled separately from power current cables.
A qualied technician must install the electri
-
cal supply to the equipment.
7. Notes for installation
• The electrical installation and protection must be in ac-
cordance with local regulations.
• The basic/controller modules and module expansions
must be left continuously connected to voltage so as to
ensure function is possible at any time.
• Mains switches on the supply side must thus be restrict-
ed to emergency or main switches that are normally left
in operating position.
• Before commissioning, check whether all electrical
components have been connected correctly.
