Instructions for working safely
Before working on the hydraulic system
•
•
•
•
Work on the heating system (for example, installation, connection and initial start-up) must only be carried out by authorised
persons who have successfully completed the requisite technical training. These include heating engineers whose technical
training and know-how means that they have experience of professionally installing and maintaining heating systems.
Lead tamper-proof seals must not be damaged or removed.
Make sure that the safety valves comply with the requirements of EN 12828 when connecting on the heating side, and with
the requirements of EN 12897 when connecting on the domestic water side.
Use only genuine ROTEX replacement parts.
Electrical installation
•
•
•
•
Electrical installations may only be carried out by qualified electrical technicians under observance of the relevant electrical
guidelines and the regulations of the electric utilities company.
Compare the mains voltage (~230 V, 50 Hz) indicated on the nameplate with the supply voltage before connecting to the
mains.
Before beginning work on live parts, disconnect them from the power supply (switch off main switch, remove fuse) and
secure against unintentional restart.
Equipment covers and service panels must be replaced as soon as the work is completed.

1 x Safety
Corrosion protection
In some regions, aggressive drinking water is supplied by public utility companies which can cause corrosion damage, even in high
grade special steels. Ask your water utility whether the use of hot water storage tanks made from stainless steel results in
problems with corrosion in your area.
If needed, appropriate water treatment is required.
Equipment installation location
For safe and fault-free operation, it is necessary that the installation location of the ROTEX BIV- Control fulfils certain criteria.
Information about this can be found in the Chapter "Installation".
Information on the installation site of other components can be found in the associated documentation supplied with them.
Hydraulic system connection
With bivalent operation, particularly in conjunction with the use of solar energy, the temperature in the cylinder can exceed 60 °C.
• Therefore, some form of scalding protection must be included when you install the system (e. g. VTA32) .
• To prevent the HPSU Bi-Bloc heat pump from switching off because of high pressure, a return temperature limiter (e. g. RLB
14 01 14) must be installed in the system.
Sanitary connection
With sanitary connection the following must be observed;
•
•
•
EN 1717 - Protection of domestic water from contamination in domestic water installations and general
requirements concerning safety equipment for the prevention of domestic water contamination by back-flow
EN 806 - Technical regulations for domestic water installations (TRWI),
and, in addition, the country-specific legal regulations.
Operation
•
Only operate the ROTEX BIV- Control after completion of all installation and connection work on the heating system.
Instruct the owner
•
6
Before you hand over the heating system with bivalent control, explain to the owner how he/she can operate and check the
heating system.

Product description
Die ROTEX BIV- Control permits the combined use of an HPSU Bi-Bloc heat pump together with the ROTEX A1BO, A1BG or GSU
fossil-fuel heat generators in a heating installation. Depending on the user's presets, the heating of the hot water and the heating
system by a heat pump, a condensing boiler and, if a solar system is connected, by solar heat is controlled fully automatically.
At normal outside temperatures (tA), between the bivalence
temperature (tbiv) and the heating limit temperature (tHmax),
the heating of the building is performed entirely by the HPSU
Bi-Bloc heat pump. Depending on the hot water temperature
and the system parameters set on the HPSU Bi-Bloc heat
pump, the hot water generation is operated by environmentally friendly energy from the ambient air and a proportion of
post heating by the condensing boiler.

t biv
A1
GSU
HPSU
Operation with the solar system is possible at any time,
however.
If the heat output (Q) from the HPSU Bi-Bloc heat pump is not
high enough to heat the building (e. g. at temperatures below
freezing point, this decreases continuously), the condensing
boiler (A1BO, A1BG, GSU) is switched on to provide heating
assistance.

Efficiency range of the heat pump
Advantages resulting from the use of the ROTEX BIV- Control:
– Preferential heating with cost-effective indirect solar heat pump energy,
– Further use of an existing fossil-fuel heat source.
– The expensive fossil heat energy is only switched on at very low outside temperatures.
– Other electric auxiliary heating (booster heater, backup heater) can be dispensed with.
A further plus for the owner of the heating installation is the universal use of various ROTEX condensing boilers without having
to replace expensive control electronics, as well as the compact and partially pre-wired construction.

BIV Control Unit
The ROTEX BIV- Control controls the heat sources by means of their respective internal controllers.
Depending on the outside operating conditions and the requirements for hot water generation and heating assistance, 3-way
diverter valves and the heat sources are switched so that the heat demand is covered in the most energy-saving way possible.
When there is sufficient yield from solar energy, the unpressurised cylinder circuit is always preferably heated by the solar
collectors. The domestic water is heated indirectly in a corrosion-resistant stainless steel corrugated pipe heat exchanger. On its
way to the top, it continuously absorbs the heat from the storage tank water.

BIV- Control with HPSU (H - heating function only) and GSU (see Chapter 6.3 for key)
Run the connecting cable for operating mode changeover between the controller for the ROTEX condensing boiler (modem
connection) and the ROTEX BIV- Control (M1, M2) and connect it according to the wiring diagram (Fig. 3-10).
On condensing boilers where control of the boiler pump is not possible using the internal controller, the boiler
pump (PAUX) must be controlled by means of a separate connection.
Contact our technical customer service before starting the installation.
For already-installed condensing boilers only:
• Disconnect the cable for the 3-way diverter valve (3UV3) from the
controller on the ROTEX condensing boiler (PCB plug J2, connections 2,
3, 4) (Fig. 3-7).

Adapting controllers to ROTEX boilers
Preinstalled controllers are adjusted to the particular ROTEX boiler at the factory. The settings in this case always relate to use
as a single heat source.
When a Solaris solar system is connected, the controllers of the particular ROTEX boilers for bivalent-parallel operation must be
set so that the hot water generation is carried out primarily by the Solaris solar system (see associated installation and operating
manuals for the boilers and the Solaris solar system).
Adapting the controllers for bivalent-parallel operation should only be undertaken during the initial start-up and
when replacing boilers.

Settings for ROTEX A1 and GSU condensing boilers and for cylinder temperature sensors
1.
Set the boiler controller to the "Hot water" mode (see operating manual for the installed controller).
2.
A1BO, A1BG: Insert the cylinder temperature sensor for the condensing boiler to a depth of 1.00 m and the cylinder
temperature sensor for the HPSU to a depth of 0.80 m into the HybridCube (HYC) DHW cylinder.
GSU: Insert the cylinder temperature sensor for the condensing boiler to a depth of 73 cm and the cylinder temperature
sensor for the HPSU to a depth of 0.68 m into the DHW cylinder.
3.
Set the hot water target temperature on the boiler controller to the design value, which is calculated as follows:
Maximum setting for the hot water target temperature* on the HPSU Bi-Bloc heat pump:
*
_____ °C
+ Value of parameter 6-01 for the HPSU Bi-Bloc heat pump:
+ _____ K
+ Minimum setting difference:
+
= Design value for the boiler controller for the hot water target temperature:
= _____ °C
5K
It must be agreed with the owner, what maximum hot water target temperature is to be set on the controller for the HPSU Bi-Bloc heat pump.
This value should not exceed 60 °C.
To do this, any setting limits for the hot water target temperature on the Expert level for the particular boiler controller may
have to be adjusted (see the associated installation and operating manual).
4.
Compare the temperature values for the two cylinder temperature sensors on the controller displays.
If the cylinder temperature sensor for the condensing boiler has been inserted a little deeper, the cylinder
temperature measurement for the boiler must be a little lower than the value from the cylinder temperature
sensor for the HPSU Bi-Bloc heat pump.
If the cylinder temperature measurement for the condensing boiler is higher, it can happen that the HPSU BiBloc heat pump continues to request, but the condensing boiler signals that the cylinder temperature has been
reached and ends its heating of the DHW cylinder.
• Check the insertion depths of the sensors.
• Correct the sensor settings (insertion depth/settings in the controller) or replace the sensor.
5.
Restrict the maximum temperature for the condensing boiler preferably to 70 °C.

After the initial start-up
WARNING!
Live parts can cause an electric shock on contact and cause life-threatening burns and injuries. Running the
system may also cause short circuits which will damage the electronics.
• Only connect and disconnect sensors when the heat source is switched off and disconnected from the
power supply.
The heating installation must tested under all operating conditions before being handed over to the owner. It is necessary to
perform the following checks in this respect:
• Check that the condensing boiler switches on and off under all operating conditions.
If the boiler is switched on or off contrary to the expected state, the function of relay K1 will have to be inverted. Set
BIV- Control DIP switch "S1" to "OFF", see Chapter 5 "Functional description", Table 5-1.
Relay contact K1 (terminals M1 and M2) is connected to the modem input on the ROTEX boiler control panel.
When the modem contact is short circuited, the ROTEX condensing boiler is switched to stand-by operation.
Stand-by operation => normal operation = expected state.
An inversion may be necessary if a boiler from a third party manufacturer is connected, or if a burner inhibit
contact (BSK) is used to control the operation of the boiler. If the BSK were to be used with a ROTEX boiler,
the boiler pump would also run as a rule, something that is not desired for this application.
•
Check the switching states of the 3-way diverter valve (3UV3) under all operating conditions.
When there are simultaneous requests for the backup heater and the booster heater from the HPSU Bi-Bloc heat pump
controller, in normal operation the 3UV3 is switched to heating priority (valve outlet B, see Fig. 3-4 to Fig. 3-5).
• If the 3UV3 is installed contrary to the illustrations in Fig. 3-4 to Fig. 3-6, so that connections A and B are interchanged,
the BIV- Control DIP switch "S2" will have to be set to "OFF" to invert the function of the 3-way diverter valve (3UV3),
see Chapter 5 "Functional description", Table 5-1.
If preference is given to charging the DHW cylinder (cylinder priority switching) when there are simultaneous requests
for the backup heater and the booster heater from the HPSU Bi-Bloc heat pump controller, the BIV- Control DIP switch
"S3" will have to be set to "OFF" to invert the function of the 3-way diverter valve (3UV3), see Chapter 5 "Functional
description", Table 5-1.
Individual settings for heating or cooling operation on the particular heat sources may only be made after a fault-free start-up.

Recommendations for disposal
The ROTEX BIV- Control has an environmentally friendly design. During the disposal process, the only waste created is that which
can be used for material or thermal recycling. The materials used that are suitable for material recycling can be separated
according to single variety.
ROTEX has complied with the standards for environmentally-friendly disposal as a result of the environmentallyfriendly design of the ROTEX BIV- Control. Proper disposal in compliance with the respective national regulations
of the country of use is the responsibility of the user/owner.

3-way diverter valve 3UV3
Mode of operation
The 3-way diverter valve (3UV3) switches between the hot water heating and heating assistance modes according to the request
from the bivalence controller and hence the HPSU Bi-Bloc heat pump.
If hot water heating with the heating element is requested by the heat pump, the 3-way diverter valve (3UV3) switches to position
"A". If heating assistance is requested, the valve is driven to position "B". If hot water heating and heating assistance are
requested simultaneously, the 3-way diverter valve switches according to the priority setting, which is set via DIP switch 3 (see
Table 5-4 and Table 5-5, Section 5.5).
For the position of the 3-way diverter valve (3UV3) in the event of a power failure or disconnection, see Chapter 3.2.3, Connection
variants 1 and 2.
The method of operation of the 3-way diverter valves 3UV1 and 3UV2 is described in the other applicable documents.

Table 5-7 Switching of relay K3 when DIP switch setting S5 = "ON", (request for hot water)
When the "chimney sweep" button is operated, K3 is always closed (AUX output = "ON").
In order to start the "chimney sweep" (maximum output) function, then, this must also be initiated directly at the
heat source by means of its "chimney sweep" button.
The switching process, as well as the "chimney sweep" function of switching relay K3 can be inverted by changing DIP switch S4 to the "ON" position. Consequently all the processes carried out by relay K3 will be inverted.

Emissions measurement
WARNING!
Live parts can cause an electric shock on contact and cause life-threatening burns and injuries.
• Comply with the relevant safety at work regulations.
The automatic function for emissions measurement prevents the control of the condensing boiler from being influenced any
further by the BIV- Control.
1.
Press the button on the BIV- Control to enable the fossilfuel boiler for emissions measurement.
The control of the condensing boiler is transferred to
stand-by by the BIV- Control and is no longer influenced by it.
The emissions measurement must be performed
within 30 minutes.
2.
Perform the emissions measurement in accordance with
the instructions for the particular condensing boiler.
3.
The enabling for emissions measurement ends and the
bivalent-parallel operating mode begins:
a) Automatically after 30 minutes elapse.
b) By renewed pressing of the button to enable the fossilfuel boiler for emissions measurement.
c) By disconnecting the mains / operating the mains
switch on the BIV- Control.
