The external sensor (protection class IP 67) is a function-critical
accessory and included in the scope of supply.
NOTE
If the external sensor is not installed or defective, the heat-
ing and heat pump control automatically sets the external
temperature to -5 °C. The status display of the control unit
lights up red, the screen of the control unit reports an er-
ror.
IMPORTANT
Mount the external sensor on the north or northeast side
of buildings. The sensor must not be exposed to direct
sunlight. The cable gland must point to the base.
1. Open the housing of the external sensor and align ≥ 2 m
over the base of the fastening point.

external sensor to the wall.
NOTE
Dowels and screws for fastening the external sensor are
not included in the scope of supply.
3. Loosen cable gland and lead a 2-wire cabel (Ø 5- 9,5mm, cross
section ≤ 1.5 mm² per wire, cable length ≤50 m) through the
cable gland into the housing.
4. Fit the cable wires with wire end sleeves, place them on the ca-
ble clamps of the external sensor and tighten them with a torque
of 0.5 Nm.
5. Tighten cable glands with a torque of 2.5 Nm and close the
housing of the external sensor. Ensure that the housing seal
and the sealing surfaces are clean and that the housing seal is in
the correct position.
IMPORTANT
No moisture may be trapped in the housing. If necessary,
completely dry the inside of the housing before mounting
the housing cover.
Ensure that the tightness of the housing is guaranteed by
mounting it tension-free and that no water can penetrate
the housing of the external sensor at any time (for instance
during the construction phase).

DANGER
Danger of fatal injury due to electric current!
Electrical connections may be installed only by qualied
electricians.
Before opening the unit, disconnect the system from the
power supply and secure it from being switched back
on!
Softwareupdate / ‑downgrade
Software updates/downgrades can be carried out via the USB in-
terface on the control unit of the heating and heat pump control-
ler.
1. Expose the USB interface on the control unit.
Part 1 of the controller manual, program area “Service“, sec-
tion “Basic Information on the operation“
2. Insert a USB stick with the software into the USB interface
and follow the on-screen instructions.
IMPORTANT
Only install updates/downgrades that are cited as “valid
updates” (“Gültiges Updates”) in the screen list.
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 the
necessary components have been detected.
page 14, “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.
A screen may then appear prompting you to enter a hydraulic-
code. In this case, enter and conrm the hydrauliccode. If a hy-
draulic code is given, do not change this hydrauliccode, but on-
ly conrm it.
NOTE
The hydrauliccode is axed to the hydraulic unit/ to the
wall-mounted controller.
NOTE
The hydrauliccode can be read later in the “System status”
menu. If necessary, it can be changed there.
page 21, “Query the system status“

11Subject to technical amendments without prior notice | 83055400kUK – 2.1 | ait-deutschland GmbH
The following display then appears:
The question always appears when the controller volt-
age is switched on, provided it has been interrupted for
>20 hours.
If the date and time are correct, select and click . Otherwise,
select and click , set the correct date, time and time zone and
save. Then select and click on the navigation arrow in the 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 (additional heating generator) is released by the control-
ler until the display is conrmed with .
NOTE
No heat generator runs during a cold start of air/water heat
pumps.
IMPORTANT
The unit can be damaged if the display is conrmed with
, although the system is not properly lled.
For brine/water heat pumps it is necessary to select which heat
source uid is to be used.
Brine
Must be selected if the heat pump is operated with a
brine-water mixture (= standard). Whether probes or
surface collectors are used is irrelevant.
If there is an intermediate heat exchanger on the heat source
side:
Water Brine
Must be selected if water is used as the heat source me-
dium on the primary side of the intermediate heat ex-
changer and a brine-water mixture is used on its second-
ary side.
Water Water
Must be selected if water is used as the heat source me-
dium on both the primary and secondary sides of the in-
termediate heat exchanger. For the water/water setting
the heat source inlet temperature must be at least 7°C or
higher.
IMPORTANT
Performance-controlled brine/water heat pumps with re-
frigerant R407C shall only be operated on the secondary
side of the intermediate heat exchanger and not with wa-
ter as the heat source medium. Therefore, the menu en-
try “Water Water” is not visible in the display with per-
formance-controlled brine/water heat pumps with refrig-
erant R407C.
The minimum temperature of the heat source (min. heat source
temp) will be set automatically depending on the selected medi-
um.
page 57, “System setting during commissioning“, “min.
heat source temp”
NOTE
If no heat source is selected and the enquiry is only an-
swered by navigating to and selecting , “Brine” is auto-
matically set as the heat source.
A subsequent change of the heat source medium as well
as “T-HS min” is only possible with customer service access.

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.
After that, the navigation screen appears.
NOTE
With some devices, the compressor is now heated initially.
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.

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.
page 12, “Startup guide“ and page 13, “Reset start-up
parameters“
If you do not wish to use the startup guide, rst make the settings
required for your system in the “System settings” menu (page
27, “Determining system setting“).
Then set the desired temperatures ( page 24, “Determining
temperatures“).
Then make all other settings that are necessary for the conditions
of your installation.
Startup guide
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.
You will be guided step-by-step through several selection 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.
Further queries will follow.
For more information on the commissioning assistant, please re-
fer to the corresponding sections in this operating manual.
NOTE
As soon as the startup guide has been executed once, the
menu item “Reset start-up parameters” appears on the dis-
play instead of the “Startup guide” menu item.

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 START-UP 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:

Emergency mode
The emergency mode provides heating operation and domestic
hot water preparation as well as the frost protection function and
the screed heating program even if, after switching on the con-
troller voltage and during the self-test (POST Screen)
●one or more basic system components were not detected,
●at least the system components required for the emer-
gency mode were detected.
The emergency mode is activated automatically.
NOTE
For units where a hydraulic code must be entered during
commissioning, the emergency mode can only start if this
hydraulic code has been entered.
A connection error is rst displayed on the screen of the heating
and heat pump controller.
Im Bildschirm des Heizungs- und Wärmepumpenreglers wird zu-
nächst ein Kommunikationsfehler ausgegeben.
Example of a connection error displayed on the screen.
Beispiel eines im Bildschirm angezeigten Kommunika-
tionsfehlers
The navigation screen is displayed by turning the “rotary push-
button”.
If the emergency mode is active, corresponding warning symbols
are shown in the standard screen.
During the emergency mode, the compressor request is locked.
To ensure heating operation and domestic hot water preparation,
set the “2nd heat gen.” option as the “Heating” operating mode
and the “Domestic hot water” operating mode.
NOTE
The “2nd heat gen.” setting increases the energy consump-
tion.
During the emergency mode, the search for missing system com-
ponents continues in the background.
If the missing components are detected during the emergency
mode, the system is automatically restarted.
NOTE
The operating modes “Heating“ and “Domestic hot water“
must be manually reset from the option “2nd heat gen.” to
the option “Auto(matic)”.
If the compressor of the heat pump fails during operation, the op-
erating modes “Heating” and “Domestic hot water” can also be
set to the option “2nd heat gen.” if required.
This can ensure that heating and domestic hot water are prepared
until the cause of the compressor failure has been rectied.

Program area “Cooling”
The “Cooling” function with automatic changeover between
heating mode and cooling mode (depending on requirements)
can be used with a mixing circuit.
In order to use the cooling function with further mixing circuits,
the installation of the expansion board (extra-cost accessory) is
required.
The program area “Cooling” must be set by authorised service
personnel during commissioning.
Necessary setting:
Mixing circ 1 = Cool
page 27, “Determining system setting“, “Mixing circ 1”
IMPORTANT
If a cooling circle mixer is connected, it is imperative to ac-
tivate the function “Cooling”, as otherwise malfunctions
will occur in the mixer connected.
IMPORTANT
The use of cooling requires that you integrate a dew point
sensor in the system. This must then either be connected
in series with the cooling sensor or used instead of the
bridge, if cooling is provided via the ow cooler.
NOTE
The minimum ow temperature of cooling is factory set to
18°C. This value can be changed in the menu “Determin-
ing temperatures” in the menu item “min. ow cooling”
IMPORTANT
For brine/water heat pumps with integrated hydraulic
components, do not set the minimum ow temperature of
cooling to <18°C.
page 24, “Determining temperatures“
If the cooling function is set, the symbol for the program area
“Cooling” will appear in the navigation screen

NOTE
Activate the automatic mode only during the summer
months or shut o the cooling during the heating period
by means of a room thermostat.
Otherwise, it is possible that, depending on the location of
the outdoor sensor, the system will switch to cooling if the
outdoor temperature exceeds the set temperature.
NOTE
Automatic operation also means that during the summer
months the system will automatically change over to heat-
ing mode or to the operating mode selected in the “Heat-
ing” program area as soon as the outside temperature
drops below the preset value.
In order to ensure that the system does not start to heat
during the summer months, the operating mode for the
heating can be set to “O”.
