IMPORTANT
The unit can be damaged if the display is conrmed with
, although the system is not properly lled.
After conrming the security question, the startup guide starts.
ATTENTION
The Startup guide must always be run, as it is the only way
to address the connected heat pumps.
page 7, “Startup guide“
If this screen
is then displayed, disconnect the heating and heat pump con-
troller from the power supply, check the 3-pole cable for the BUS
connection and rectify any faults found.
Startup guide
So long as the heat pumps have not yet been congured, the
“GO” symbol ashes at the top right of the navigation screen.
Navigating to and clicking on “GO” calls up the startup guide. This
assistant will guide you through the most important settings of
the regulator during initial commissioning.
After the initial commissioning has been completed, the “GO”
symbol will no longer be displayed.
If the startup guide is not called up via the ashing “GO” symbol
in the navigation screen, this can be done in the “Service” pro-
gram area.
NOTE
As soon as the startup guide has been executed once, the
menu item “Reset Startup Parameters” appears on the dis-
play instead of the “Startup guide” menu item.
Switching on / Commissioning
When switching on the controller voltage or after a restart of the
heating and heat pump controller (reset), a self-test is carried out
to check whether the basic components of the heat pump system
are available.
The components displayed vary depending on the heat
pump type.
The self-test (POST = Power on startup) can take up to
5minutes (Time-out).
Once all the basic components of the system are detected within
5 minutes, the system is ready for operation.
NOTE
If the self-test fails, an emergency mode is activated, if at
least the necessary components have been detected.
page 10, “Emergency mode“
If the system is ready for operation but not yet congured (initial
switching on), then the language selection is displayed rst.
Select the display language: part 1 of the controller manual,
section “Basis information on the operation“.
NOTE
The language must be conrmed.
Then click on the navigation arrow in the language display. After
that a security question appears:
The security question always appears when the control-
ler voltage is switched on or after a restart of the heating
and heat pump controller (reset).
This screen is no longer displayed if the heat pump or
ZWE1 has more than 10 operating hours.
No ZWE (second heat generator) is released by the controller until
the display is conrmed with .

NOTE
Do not press the conrmation prompt on the screen until
the LINBus connection to heat pump 2 has been plugged
into the control board and the LINBus connection to heat
pump 1 has been unplugged from the control board.
As soon as the conrmation prompt is pressed the addressing of
heat pump 2 begins.
The screen does not change until it has nished addressing heat pump 2.
NOTE
Do not press the conrmation prompt in the screen until
the LINBus connection to heat pump 1 has been plugged
into the control board.
As soon as the prompt is conrmed the system checks whether
the connection with both heat pumps can be established.
Following successful checking and connection to both heat pumps the Startup guide
continues with further input prompts, which concern the settings of your system, for
example, with.
Further queries will follow.
The startup guide leads you step-by-step through several selec-
tion options used to set up your heat pump.
For example:
For the number of the control setting, please refer to the hydraulic diagrams we have
published.
If 2 heat pumps are operated at the hydraulic module, the heating
and heat pump controller must now address each individual heat
pump. Heat pump 1 is addressed rst, which is why the LINBus
connection to heat pump 2 has to be disconnected temporarily
from the control board of the heating and heat pump controller.
NOTE
Do not press the conrmation prompt in the screen until
the LINBus connection to heat pump 2 has been discon-
nected from the control board.
NOTE
If necessary the assignment of the heat pump be changed
any time.
page 34, “Device assignment“
As soon as the conrmation prompt is pressed the addressing of
heat pump 1 begins.
The screen does not change until it has nished addressing heat pump 1.

After that, the following screen appears:
NOTE
The heating phase until the compressor starts can take
several hours when starting up for the rst time.
With dual air/water heat pumps the ow is monitored
while the pump is running. If the ow is not ok, the heat
pump does not start up and no error is displayed. To this
end, check the ASD input, if it is not set to ON the ow is
too low.
page 16, “Query inputs“
FIX STARTUP PARAMETERS
With installer or customer service access, it is possible to save the
settings made during commissioning (= startup guide). This al-
lows you to quickly and easily reset the system to the status it had
at startup.
The data is stored on the circuit board of the control unit.
Follow the instructions on the screen and save the set-
tings.
You can also save the settings to an external USB stick.
RESET STARTUP PARAMETERS
If your heat pump was commissioned by an authorised customer
service partner and the startup parameters have been stored, you
can use this menu item to restore these parameters.
This may be helpful if settings have been changed and let to a
system malfunction. Please Notice that all settings such as heat-
ing curves, system settings, set values will be reset to the values
applicable at commissioning.
The programmed switching times are not aected by this.
You will be guided through the following menu items:
