Safety requirements
All installation and wiring work on the controller must only be carried out
in a zero volt state. The opening, connection and commissioning of the
device may only be carried out by competent personnel. While doing so,
they must observe all local safety requirements.
This device is state of the art and meets all necessary safety regulations. It may only be used
in accordance with the technical data and the safety requirements and regulations listed below. When using the device, also observe the statutory and safety regulations apposite to
the particular use. Any other use will automatically void all warranty rights.
• The device must only be installed in a dry interior room.
• It must be possible to isolate the controller from the mains using an omnipolar isolating
facility (plug/socket or 2-pole isolator).
• Before starting installation or wiring work, the controller must be completely isolated
from the mains and protected against reconnection. Never interchange the safety low
voltage connections (e.g. sensor connections) with the 230 V connections. Destruction
and life threatening voltages at the device and the connected sensors may occur.
• Solar thermal systems can become very hot. Consequently there is a risk of burns. Proceed with caution when fitting temperature sensors.
• For safety reasons, the outputs should only be left in manual mode when testing. In this
operating mode, no maximum temperatures or sensor functions are monitored.
• Safe operation is no longer possible if the controller or connected equipment exhibits
visual damage, no longer functions or has been stored for lengthy periods in unsuitable
conditions. If this is the case, disable the controller and equipment and secure against
unintentional use.
Maintenance
If treated and used correctly, the device will not require any maintenance. Use a cloth moistened with mild alcohol (such as methylated spirits) to clean. Never use corrosive cleaning
agents or solvents such as chloroethylene or trichloroethylene.
No components relevant to long term accuracy are subject to loading if the device is used
correctly. Consequently long term drift is extremely low. The device therefore cannot be calibrated. Thus applying any compensation is impossible.
The design characteristics of the device must not be changed during repairs. Spare parts
must correspond to the original spare parts and must be used in accordance with the build
version.
Disposal
• Devices no longer in use or beyond a state of repair must be disposed of
in an environmentally responsible manner by an authorised collection point.
They mus never be treated as ordinary household waste.
• We can undertake the environmentally responsible disposal of devices
sold by the Technischen Alternative company upon request.
• Packaging material must be disposed of in an environmentally responsible
manner.
• Incorrect disposal may result in considerable damage to the environment,
as many of the materials used require professional handling.

Sensor installation
Correct arrangement and installation of the sensors is extremely important for correct functioning of
the system. To this end, also ensure that they are completely inserted in their sensor wells. The cable
fittings provided serve as strain relief. When used outdoors, no water must be allowed to penetrate
the sensor wells (risk of frost). The contact sensors must be insulated well to protect them from being influenced by the ambient temperature.
Sensors should generally not be exposed to moisture (such as condensation) since this can diffuse
through the cast resin and damage the sensor. If this happens, heating the sensor to 90 °C for an
hour may help. When using sensor wells in stainless steel cylinders or swimming pools, particular
attention must be given to their corrosion resistance.
• Collector sensor (grey lead with junction box): Either insert into a pipe which is brazed or riveted
directly to the absorber and protrudes from the collector housing, or insert a tee into the flow
manifold of the outermost collector into which the sensor well, together with the brass cable fitting (= protection against moisture), can be inserted; then insert the sensor. To protect against
lightning damage, the junction box has a surge protection (voltage dependent resistor) which is
clamped in parallel between the sensor and the extension cable.
• Boiler sensor (boiler flow): This sensor is either inserted into a sensor well in the boiler or fitted
to the flow line as close to the boiler as possible.
• DHW cylinder sensor: The sensor required for the solar thermal system should be used with a
sensor well for finned tube heat exchangers just above the exchanger or, if integrated smooth
tube heat exchangers are used, in the lower third of the exchanger or the exchanger’s return outlet so that the sensor well protrudes into the heat exchanger tube. The sensor monitoring the
heating of the DHW cylinder by the boiler is installed at a level corresponding to the amount of
domestic hot water required during the heating season. The supplied cable fitting acts as strain
relief. Installation below the associated coil or heat exchanger is not permissible under any circumstances.
• Buffer sensor: The sensor required for the solar thermal system is fitted in the lower section of
the cylinder just above the solar indirect coil using the sensor well supplied. The supplied cable
fitting acts as strain relief. As the reference sensor for the heating system hydraulics, it is recommended to insert the sensor into the sensor well between the centre and upper third of the buffer
cylinder, or positioned against the cylinder wall underneath the insulation.
• Pool sensor (swimming pool): Fit a tee into the suction line immediately on the pool outlet and
insert the sensor with a sensor well. In the process, ensure the material used is corrosion-resistant. A further option would be to fit the sensor as a contact sensor with appropriate thermal insulation against ambient influences.
• Contact sensor: Use scroll springs, pipe clips, etc. to attach the contact sensor to the respective
line. Ensure the material used is suitable (corrosion, temperature resistance, etc.). Then insulate
the sensor thoroughly so that the pipe temperature is captured accurately and ambient temperatures cannot falsify the result.
• DHW sensor: A rapid reaction to changes in the water volume is extremely important when using
the controller in systems that generate domestic hot water by means of an external heat
exchanger and variable speed pump (freshwater module). Therefore fit the DHW sensor directly
on the heat exchanger outlet. This ultra-quick sensor (special accessory, type MSP) should protrude into the output with the aid of a tee sealed in with an O-ring. The heat exchanger should be
installed upright with the DHW outlet at the top
• Radiation sensor: The parallel collector orientation is important in order to obtain a measurement that corresponds to the collector position. Consequently it should be secured to the sheet
steel covering or adjacent to the collector on an extension of the mounting rail. To this end, the
sensor casing has a blind hole that can be opened at any time. The sensor is also available as a
wireless version.
5
• Room sensor: This sensor is intended for installation in the living space (reference room). Do not
install the room sensor near a heat source or window. By simply replugging a jumper inside the
sensor, each room sensor can also be used exclusively as a remote adjuster (no room temperature influence). It is only suitable for operation in dry rooms. The sensor is also available as a
wireless version.
• Outside temperature sensor: This sensor is installed on the coldest wall (usually facing north)
some two meters above the ground. Avoid temperature influences from nearby air shafts, open
windows, cable ways, etc. It must not be subjected to direct insolation.
Electrical connection
This must only be carried out by a qualified electrician in accordance with the relevant local regulations.
Note: In line with regulations, the system must be equipped with protection against lightning (surge
arrester). Sensor failures due to thunderstorms and static electricity are usually the result of missing
or incorrect earthing or missing surge protection.
Caution: Only work inside the module when the power supply is at zero volt. Assembling the device
with the power connected may result in damage.
Connect all sensors and pumps/valves as they are numbered in the respective program.
In the mains voltage range, fine wire cross-sections of 0.75 - 1.5 mm² are recommended, except for
the supply cable.
A terminal strip is provided in the 230 V terminal box for connection of the earth conductor (PE). All
cables can be fixed with a locking clamp (= strain relief) immediately after termination. Subsequently,
side cutters are required to remove the locking clamps; therefore, more clamps than necessary are
provided.

Mains connection
Power is supplied through a power supply unit integrated into the module. The mains connection
must therefore be 230 V 50 Hz. This is also the voltage conducted by the output relay. The integral
power supply unit also supplies power to the CAN bus.

Sensor leads
Sensor terminal diagram
UVR610S
UVR610K
Sensors are always connected across the relevant sensor terminal (S1 – S6) and sensor earth
(GND).
In order to prevent measurement fluctuations and ensure perfect signal transmission, sensor leads
must not be subject to external negative influences through 230 V cables.
Never run sensor leads together with mains voltage cables in the same conduit.
When using non-screened cables, route sensor leads and 230 V cables either in separate cable conduits or with a minimum clearance of 5 cm.
Sensor leads for PT100 or PT500 sensors must be screened.
If screened cables are used, the screen must be connected to the sensor earth (GND)
All sensor leads with a cross-section of 0.5 mm2 can be extended to up to 50 metres. With this lead
length and a PT1000 temperature sensor, the measuring error is approximately +1 K. A correspondingly larger cross-section is required for longer leads or a lesser measuring error.
The connection between the sensor and the extension can be made by pushing heat shrink tubing
(trimmed to 4 cm) over one core and twisting the bare wire ends. Solder the connection if one of the
wire ends has been tin-plated.
Then push the heat shrink tubing over the connection and heat up carefully (e.g. with a lighter) until
it sits tightly over the connection.

Data cable for DL bus
The DL BUS consists of just 2 wires: DL and GND (sensor earth). The DL BUS itself supplies the necessary power for the DL BUS sensors.
Cables can be routed with a star topology but also in serial formation (from one device to the next).
Any cable with a cross-section of 0.75 mm², and measuring up to 30 m in length, can be used as a
data link. For lengths greater than 30 m, the use of screened cables is recommended, which increases the reliable length of the cable to 100 m.
If screened cables are used, the screen must be connected to GND.
Long cable conduits routed closely next to each other for mains and data cables result in faults being
induced into the data cables from the mains. We therefore recommend a minimum clearance of 20
cm between two cable conduits or the use of screened cables.
Use separate, screened cables when capturing data from two controllers with a single datalogger.
Never run the data cable together with a CAN BUS cable in the same conduit.
Terminal diagram, DL bus data cable
Bus load of DL sensors
A 2-pole cable provides both the power supply and the signal transfer from DL BUS sensors. An additional power supply by means of an external power supply unit (such as with the CAN BUS) is not
possible.
Take the "Bus load" into consideration as sensors have a relatively high current demand:
The UVR610 supplies a total bus load of 100%. The bus loads of the electronic sensors are listed in
the technical data of the relevant sensors.
Example: The electronic sensor FTS4-50DL has a bus load of 25%. Consequently up to four FTS450DL can be connected to the DL bus.
CORA devices
CORA devices can be connected to the UVR610 controller by cable (software version 1.09 or higher).
They are connected at the controller's DL bus. CORA devices connected in this way have no effect
on the DL bus load or other DL devices. If using CORA-DL, ensure correct polarity.

CAN Bus network
Terminal diagram, CAN bus cable
Guidelines for the topology of a CAN network
Technical principles
The CAN BUS comprises the cables CAN-High,
CAN-Low, GND and one +12 V supply cable for
BUS components without their own power supply.
The combined total load of all devices with 12 V
and 24 V supply must not exceed 6 W.
Design CAN networks in a linear fashion and set a
terminator at each network termination. This is
ensured by the termination of the end devices. In
the case of larger networks (covering several
buildings), problems can occur through electromagnetic interference and potential differences.
To avoid or to the greatest extent manage such
problems, take the following measures:
• Cable screening
The BUS cable screen must be connected well at every node to provide continuity. For larger networks we recommend including the screen in the equipotential bonding, in line with the examples shown.
• Equipotential bonding
As low an ohm connection as possible to the earth potential is particularly important. Where
cables enter buildings, ensure that the cable entries are in the same location where possible and
that all are connected to the same equipotential bonding system (SingleEentryPoint principle). The
purpose is to create potentials that are as similar as possible, in order to achieve the smallest
possible potential difference to adjacent lines in case one line suffers a voltage surge (lightning
strike). Also ensure a corresponding clearance between the cable and lightning protection systems.
The equipotential bonding also has positive properties to counteract interferences emitted from
linked cables.
10
• Avoiding earth loops
Where a bus cable is routed between several buildings, ensure that earth loops are avoided. The
reason for this is that buildings actually have different potentials compared to the earth potential. An earth loop is created when connecting one cable screen in each building directly with the
equipotential bonding system. In other words, a current flows from the higher to the lower potential.
For example, if lightning strikes near one of the buildings, the potential of that building will briefly
be raised by several kV.
In this case, the equalizing current flows to earth via the bus screen and causes an extreme electromagnetic input which can result in the destruction of the bus components.
Lightning protection
Efficient lighting protection is highly dependent on good building earthing that meets the relevant
regulations.
An external lightning protection system offers protection against a direct lightning strike.
In order to protect against voltage surges in the 230 V mains supply cable (indirect lightning strike),
appropriate lightning conductors and surge arresters compliant with local regulations must be fitted
in the upstream distribution systems.
In order to protect the individual components of a CAN network against indirect lightning strike, we
recommend the use of surge arresters specifically developed for bus systems.
Example: CAN bus surge arresters CAN-UES from Technische Alternative

... gas discharge arrester for indirect earthing
„Small“ network (within one building):
Max. cable length: 1000 m at 50 kbit/s
The screen must be continued at each network node and be connected to the device earth (GND).
The screen earthing or GND must only be implemented indirectly via a gas discharge arrester.
Ensure that no unintentional direct connection of earth or screen and the earth potential is created
(e.g. via sensors and the earthed pipework).
11
Network (across several buildings) without CAN-Repeater CAN-RP:
Max. cable length: 1000 m at 50 kbit/s
The screen must be continued at every network node and earthed at a single point, as close to the
cable center as possible. We recommend earthing the screen indirectly in the other buildings using
a gas discharge arrester. The screen is not connected with the earth (GND) of the devices.
Netzwerk (across several buildings) with CAN-Repeater CAN-RP:
Maximum cable length: subject to the set Baud rate
The screen of the disconnected network is connected at each bus converter to CAN bus earth (GND).
This screen must not be directly earthed.
Without CAN Bus surge arresters, this version only protects against potential differences up to 1 kV,
therefore cannot be considered as lightning protection. In this case, the cable screen must be
earthed at a single point between the CAN bus converters, as close to the cable centre as possible.
We recommend earthing the screen indirectly in the other buildings using a gas discharge arrester.
A CAN bus converter is similar to a repeater. It receives CAN bus signals and passes them on. Each
cable run on either side of the CAN bus converter must therefore be viewed as an independent CAN
bus network.
12
Cable selection and network topology
Screened twisted pairs have proven useful in CANopen networks. These are cables with twisted
pairs of conductors and a shared external screen. Such cables are relatively resistant to EMC interference and can still carry 50 kbit/s for up to 1000 m. The CANopen recommendations (CiA DR 3031) for cable cross-sections are given in the table below.

Bus rate
In the CAN bus / CAN settings menu of the UVR16x2, the bus rate can be set to between 5 and
500 kbit/s, whereby lower bus rates enable longer cable networks. However, in this case, the cable
cross-section must be increased accordingly.
The standard bus rate of the CAN network is 50 kbit/s (50 kBaud), which is specified for many CAN
bus devices.
Important: All devices in the CAN bus network must have the same transfer rate in order to be
able to communicate with each other. If even just one single device has a different transfer rate to
all the others, then no communication at all is possible.

Recommendations
A 2x2-pole, screened twisted pair (twist CAN-L with CAN-H or +12 V with GND) with a cable crosssection of at least 0.5 mm² and a conductor-to-conductor capacity of no more than 60 pF/m and a
nominal impedance of 120 ohms. The standard bus speed of the UVR16x2 is 50 kbit/s. This recommendation corresponds, for example, to cable type Unitronic®-BUS CAN 2x2x0.5 supplied by Lapp
Kabel for permanent installation in buildings or conduits. Theoretically this would enable a bus
length of approx. 500 m to guarantee reliable transmission.
For direct routing underground, earth cable 2x2x0.5 mm² supplied by HELUKABEL, part no. 804269,
or earth cable 2x2x0.75 mm² supplied by Faber Kabel, part no. 101465, would be suitable.
13
Wiring
A CAN BUS network should never have a star topology. Rather, the correct topology is a line from the
first device (with terminator) to the second, third and so forth. The last bus device has the termination jumper again.
Example: Connection of three network nodes (NWN) with a 2x2-pole cable and termination of the terminal network nodes (network inside one building)
Each CAN network is to be provided with a 120 ohm BUS terminator at the first and last network subscriber (= termination). This is achieved with a plug-in jumper at the back of the controller. Each CAN
network therefore always has two terminators (one at each end). Branch cables or a star topology
are not permissible for CAN wiring.
Jumper righthand side =
terminated
Jumper lefthand side =
not terminated
14
Branch cables
A CAN bus converter is used to provide reliable long branch cables. This means the branch cable is
disconnected from the other CAN bus network and can be viewed as an independent CAN bus network.
Trials at the factory have shown the following:
1) Branches with a star topology of up to 10 m will not impede transmission.
2) Up to a bus length of 250 m and a transfer rate of 50 kbit/s, data transfer works perfectly with a
low number of CAN nodes and an inexpensive J-Y(St)Y EIB KNX 2x2x0.8 KNX bus cable with a characteristic impedance of 75 to 90 ohm.
3) Up to a bus length of 150 m and with only a few nodes, the CAT 5 24AWG cable (typical Ethernet
cable in PC networks) can be used.
Changing to cable types with different characteristic impedances is only permitted via signal separation through a CAN bus converter.
However, such networks do not comply with the recommended specification. Technische Alternative
RT GmbH therefore cannot guarantee trouble-free operation if one of the three options listed above
is applied.

Outputs
Terminal diagram, switching outputs
For maximum current load of the outputs, see the technical data.
Output 6 with voltage applied
Output 6 is potential-free at the factory. If it is to be connected to the voltage of the controller, the
phase (routed out again next to terminals A6) must be connected to the root.
Example: Connection of a pump to output A6, which is
no longer potential-free.
16
Terminal diagram for analogue outputs (0-10V / PWM)
Connections AN7 – AN10 are the positive pole; the GND connection is the negative pole.
If programmed as a "switching output", a maximum of 2 HIREL-230V or HIREL-PF auxiliary relays
can be connected.
24V supply
Output AN7 can be converted to supply external devices with 24 V=. To do this, plug-in jumper J2
must be moved from the upper to the lower position.
24V= supply active
The combined total load of all devices with 12 V and 24 V supply must not exceed 6 W.
Connection for 24 V supply to terminal AN7 and sensor earth (GND).
Outputs A8 and A10 are the analogue outputs (0-10 V/PWM). A9 also remains an analogue output if
its M-Bus functionality is not used.
When using the 24 V supply, connections A8 and A10 become the positive pole; the GND connection
is the negative pole.
If programmed as a "switching output", a maximum of 1 HIREL-230V or HIREL-PF auxiliary relay can
be connected.
M-Bus
Output 9 can be converted for reading in M-Bus meters. To do this, plug-in jumper J1 must be moved
from the upper to the lower position.
M-Bus-interface active.
The connection is made at the terminals for output 9 and GND.
The M-Bus has 2 wires: M-Bus (output 9) and GND (sensor earth). The power supply for reading data
from M-Bus devices is provided by the UVR610.
Cables can be routed with a star topology or in series (from one device to the next). Ring topology is
not permitted.
A two-wire screened cable is used as the M-Bus cable (e.g. telephone cable J-Y(ST)Y 2 x 2 x 0.8 mm).
The maximum total cable length depends on the number of M-Bus devices connected and the cable
cross-section.
Never run the M-Bus cable together with a CAN bus cable or DL bus cable in the same conduit.

Both relay outputs are protected by the fuse on the relay module. Terminal "W" therefore corresponds
to phase conductor "L".
If the fuse is removed, both outputs will be potential-free whilst remaining connected to one another
via root "W".
The relay module can be connected to any two outputs between A7 and A10 if they have been programmed as switching outputs. If using on A7 and/or A9, ensure that the associated jumper is in the
upper position.

Tips on troubleshooting
Tech-support
We offer our customers free support in the event of questions or issues with our products.
Important: in order to answer your questions, we require the device serial number in every case.
If you are unable to locate the serial number, help with finding it is available on our homepage: https:/
/www.ta.co.at/en/faq/serial-numbers/
You can submit your request on our homepage using the following link: https://www.ta.co.at/en/
support-request/.
As an alternative to the contact form, you can also call us during office hours on the following number: +43 (0)2862 53635
However, before contacting our support services, please try the following solutions:
No display points to a power failure. Therefore, initially check the fuse (6.3 A (fast)) that protects the
device and the outputs (pumps, valves, etc.) from short circuits and from voltage surges in connection with the integrated surge protection. However, the glass tube fuse is not accessible, so it is necessary to measure whether voltage is present at the terminals next to output A6, where phase and
neutral are routed out. If no voltage is present there, but the actual terminals on the left of the device
are live, the fuse has blown.
Voltage
No voltage
In this case the fuse is faulty. The controller will have to be sent in for repair.
Realistic temperatures but faulty operation of the outputs indicates incorrect settings or termination.
The device is in good order if it is possible to switch the outputs ON and OFF in manual mode; check
all settings and termination.
• Do constant running and idle periods at the output result in a corresponding response? In
other words, does this pump really run if the solar pump is activated manually, or does the
heating circuit pump start instead of the solar pump?
• Are all of the sensors connected at the appropriate terminals (heat up the sensor using a
lighter and check the temperature display)?
If you still cannot find any faults in the system, we recommend installing a datalogger (C.M.I. or DLOGG) and recording the temperature curves and switching states. If the DL BUS is used for data logging, enable "data output" in "DL settings".
20
Incorrect temperatures could be the result of the following:
• Values such as -9999.9 in the case of a sensor short circuit or 9999.9 in the case of a sensor
lead break may not be the result of a material or termination error. Is the correct sensor type
selected in the input menu (KTY, PT1000, RAS, GBS, etc.)?
• A sensor can also be checked without a tester simply by swapping the sensor that is probably faulty with one that works at the terminal strip and checking the temperature display. If
the error is reproduced, the problem is the sensor. However, if the problem remains on the
same input of the device, the fault is either due to the sensor type setting or the input itself is
faulty (such as faulty surge protection).

If the sensor is faulty, note the sensor type when replacing. While it is possible to use a different type
of sensor, the parameters for that input also have to be set to suit the type of sensor used.
The current standard type used by Technische Alternative is PT1000.
KTY (2 kΩ) was the standard type until 2010/2011.
Manual switching of an output not possible:
• Ensure that output 6 is generally potential-free and therefore does not carry live voltage. Auxiliary relay outputs may also be potential-free. It is thus only possible to directly switch a 230
V consumer when the appropriate wiring has been implemented.
• If it is not possible to switch the output ON or OFF in manual mode, a message may be active
at that moment which switches the corresponding output dominantly ON or OFF (red frame
around the output symbol; indication of the message in the upper status bar). Subject to programming and user status, manual mode is not possible in this case.
Troubleshooting – hardware
In a clear case of a hardware fault, please return the device to your retailer or the manufacturer for
repair. In this case it is essential to include a fault description with the device (simply stating "the device does not work, please repair" is insufficient). Processing is accelerated if an RMA number is requested via our homepage www.ta.co.at.The defect must be clarified with our technical support
beforehand.
21
Troubleshooting – programming
The manufacturer can assist you in troubleshooting if you have the correct documentation and sufficient data to hand. The following are indispensable for this:
• a hydraulic scheme via fax or email (WMF, JPG),
• the complete program via TAPPS file or at least the function data (*.dat file) by email,
• operating system version and controller serial number,
• all existing log files or at least the (temperature) values of the inputs at the time the system
malfunctioned,
• telephone contact for describing the problem – in most cases a written fault description is
not enough.
Troubleshooting in the CAN network
To isolate the error we recommend shutting down part of the network and monitoring when the error
disappears.
General tests:
• Node numbers – no node number must be assigned twice
• Power supply to BUS subscribers (if necessary use the CAN-NT power supply unit)
• Setting of the Baud rate (even when using the CAN BUS converter CAN-BC2)
Wiring test:
All nodes must be switched off for this test.
• Resistance across CAN-H and CAN-L
• If this is in excess of 70 Ω, it indicates incorrect termination.
• If the resistance is below 60 Ω, look for too many terminations or short circuits between
cables/leads.
• Check for short circuits across GND or screen and the signal cables.
• Check for earth loops – for this the screen is undone at each node and the current tested. If
there is a current flow, an earth loop has been created by an unwanted earth connection.
