1 Safety guidelines
Danger: This device is electrically
operated. Incorrect installation or in-
correct repair attempts can cause dan-
ger to life by electrical shock.
Warning: Make sure that, before
wiring work, all lines are at zero poten-
tial! Never touch the wires and connec-
tion terminals of the device. Any
electrically live wiring work or terminal
coupling can lead to destruction of the
device and dangerous electric shock!
Installation and commissioning may
only be carried out by authorized skilled
personnel. Please pay particular attention
to the applicable accident prevention regu-
lations, the relevant standards and regula-
tions, as well as the installation and
operating instructions of additional plant
components. The controller is not repla-
cing any safety related equipment which
might be necessary on site!
Mains connection regulations:
Electric installation and fusing must com-
ply with local regulations
According to EN 60335, for stationary
devices a separator for switching off
from mains, must be installed in com-
pliance with installation regulations
(a switch for example)
The distance or the insulation from
any potential heat source must be
chosen such that the allowed ambient
temperature during operation is never
exceeded. (See technical data)
Device wiring from sensors, room de-
vices, operating devices, communica-
tion bus etc. should be separated
spatially from high voltage lines
It may be necessary to electrically
suppress strong inductive loads in
the vicinity of the controller (contac-
tors, solenoid-operated valves, etc.).
This can be done by connecting RC
circuit directly to the coil terminals of
the disturbing components.
Recommended RC circuit:: 0.047 mF,
275 VAC.
Operating requirements:
Under normal conditions the device must
be powered continuously, to ensure ope-
ration at all times. Preceding switches
should therefore be limited to emergency
or main switches that are permanently
"on".
Danger: Never connect or reconnect
an electrically live device or operate
device when open. Never run device in
a potentially explosive environment.
Never mount device on a flammable
underground. Never run device above
or below limit values as listed under the
technical data. When it’s expected that
a safe operation isn’t possible anymore
then immediately shut down device.
(For example when damage or mal-
function is obvious)
Operating instructions:
The mounting and operating instruction
provides fundamental advice and im-
portant information concerning safety,
mounting, commissioning, maintenance
and optimal use of the device. These de-
vice instructions should be completely
readand followed by installer, specialist
and plant operator before mounting, com-
missioning and operating.
All hydraulic schemes illustrated in
this manual only indicate the principle
diagrams; they do not replace a pro-
fessional installation design, which is
why in case of direct reproduction
functionality can not be guaranteed!
Technical descriptions can change wi-
thout prior notice. Possible misprints
or intermediate changes of any kind do
not entitle to any claims.
For the operator:
Let yourself be instructed by the specialist
extensively about functionality and opera-
tion of the controller. Always keep this ma-
nual near to the controller.
Warranty and liability:
Refrain from opening device or accesso-
ries. Repairs may only be carried out by
manufacturer. Only genuine parts and ac-
cessories may be used. Warranty claims
expires in case of improper installation,
commissioning, maintenance and repair of
the device, disregard of these mounting
and operating instructions or unintended
or misuse of the device.
Device settings:
By means of the integrated long-term
memory, individually entered installation
parameters as switching times remain
stored after RESET or longer power down
periods, guaranteeing reliable operation
over many years.
Declaration of conformity:
If all applicable installation and manu-
facturer instructions are taken into consi-
deration then this device complies to the
requirements of the relevant guidelines
and standards.
Waste disposal:
The device complies with the Euro-
pean ROHS directive 2002/95/EG for the
restriction on the use of certain hazardous
substances in electrical and electronic
equipment.
Under no circumstances should this
device be disposed with household waste.
The device should only be disposed at
specific waste collection points or at the
distributor.

3 Installation and connection
3.1 Installation
Opening the controller for installation
and wiring
In order for the controller base to be able
to be mounted and wired, it must first be
dismounted.
1. Lift up the front cover.
2. Using a screwdriver, lift the controller
board out of the base; see the figure
at the right.
Make sure that, before begin-
ning wiring work, all lines are at zero
potential. Before applying or remov-
ing, the controller must be switched
off (voltage-free). Never touch the
wires, rear side of the print or the con-
nections.

6
3.2 Electrical connection
230 V are applied to the mains
voltage connections on the left side,
L/ L’/ 1-5/ N. These terminals may only
be touched when de-energized, since
otherwise there is life-threatening
danger due to electric shock.
The terminal assignments
depend on and vary depending on the
selected hydraulic variant and option
marked with " * ".
eBUS connection and sensor cables
are to be installed so that they are
physically separated from the high-
voltage lines.
Information regarding installation
• The strain relief (cable ties) can be
mounted normally or reversed,
depending on the used cable thick-
ness, in order to optimally secure the
wiring.
• The electric installation and the pro-
tection have to comply with the local
regulations.
• The controller must be constantly
connected to the power supply in
order to ensure its function at all
times.
• Upstream mains switches are there-
fore to be limited to emergency or
main switches which are usually left
in operation.
• Before set-up, it is to be checked
whether all components are properly
electrically connected.
Note If there are strongly inductive loads near the controller (contactor, solenoid valves, etc.), sup-
pression might be necessary using RC elements directly at the coil connections of the dis-
turbing components. Recommended RC elements: 0.047 μF, 100 Ωfor 250 VAC (e.g.
Bosch, RIFA, etc.).

5 Start-up
Before start-up,
check the following:
• The system main switch (if available) is switched on.
• The controller is switched on or supplied with power.
• All segments of the display are shown for a short time (page 7).
• The software number and version appear (e.g. 519803 / SW 1.01).
If the controller then switches to the normal display, or, in the case of initial start-up or factory reset, to the
start menu, the internal function test was successful.
When started for the first time or af-
ter a factory reset BAS12 RESET, the
commissioning menu will appear. This is
for setting the basic parameters.

Caution: In order for all functions to run smoothly, when using a circulation pump, the flow in the circu-
lation line must always be calibrated.
ZIR 06 CIRC. CALIBRATION;
see also "8.4 Calibrating circulation volumes", page 29
After start-up,
check the following:
• The nominal temperature values are correctly set.
• The temperatures (actual values) of the connected sensors can be read off and their val-
ues are plausible.
• Domestic hot water processing possible due to a tapping process.
After start-up: Now one can continue with the hydraulic variant-specific setting/adjustment of the controller.
The most important adjusters for the selected variant are shown on the following pages.
Hydraulic applications All of the following figures are only to be understood to be pictorial schematics for illustrating
the respective system hydraulics; this does not replace the detailed planning of the fitter ac-
cording to the local conditions and no claim is made of completeness. The controller in no way
replaces the safety-related devices. Depending on the application, other system and safety
components might be required, such as shut-off valves, non-return valves, safety temperature
limiters, scalding protection etc., and must therefore be provided.

6 Hydraulic applications
6.1 Hydraulic variant 1 Fresh water station
The flow rate FLOW and the inlet tempera-
ture TKW into the heat exchanger and the
outlet temperature TWW out of the heat
exchanger are measured. The goal is to
reach the set temperature on the TWW sen-
sor at the heat exchanger outlet and to hold
it.
For this purpose, the heat supply is control-
led on the primary side via the FRIWA pump
with a speed controller, which attempts to
reach the set point on the TWW sensor and
to hold it.
*) The TPV supply sensor for the plate heat
exchanger optimizes the fresh-water control
since the temperature of the heat source is
included in the formation of the control varia-
ble for the primary pump.
