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 be-
low. 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. Pro-
ceed 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 mois-
tened 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 cal-
ibrated. 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.
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.

Generally applicable rules
For the proper use of this device
The manufacturer’s warranty does not cover any indirect damage to the unit if the technician install-
ing the unit does not equip it with any additional electromagnetic modules (thermostat, possibly in
combination with a one-way valve) to protect the device from damage as a result of malfunction un-
der the following circumstances:
• Swimming pool system: If used with a high-performance collector and heat-sensitive compo-
nents (such as plastic lines), the supply line must have an excess temperature thermostat with
all of the necessary self-closing valves (closed when without current). The controller’s pump out-
put may provide these currents, if needed. As such, all heat-sensitive parts would be protected
from overheating if the system was idle, even if steam was to form due to stagnation. This tech-
nique is mandatory, especially in systems with heat exchangers, as a failure of the secondary
pump might cause great damage to the plastic tubes.
• Conventional solar power systems with an external heat exchanger: in such systems, the sec-
ondary heat transfer medium is usually pure water. If the pump runs at temperatures below the
freezing point because of controller malfunction, the heat exchanger and other components may
suffer frost damages. In this case, a thermostat must be installed on the supply line of the secondary side after the heat exchanger to automatically stop the primary pump when the tempera-
ture falls below 5°C, regardless of the controller‘s output.
• When used for floor and wall heating: A safety thermostat must be used, just as with conven-
tional heating controllers. The heat circuit pump must be shut down if overheating occurs,
regardless of the controller‘s output, to prevent indirect damage from excess temperatures.
Solar systems - tips for idle systems (stagnation):
Generally, stagnation is not problematic and cannot be ruled out if there is a power outage, for in-
stance. In the summertime, the controller’s storage limit may switch off the system repeatedly. Every
system must thus be intrinsically safe. If the expansion container is properly designed, this is ensured. Tests have shown that the heat transfer medium (anti-freeze) is under less stress during stag-
nation than when it is just below the steam phase.
Data sheets of collector manufacturers list idle temperatures above 200°C. However, these temper-
atures generally only occur during operation with dry steam, i.e. if the heat exchange medium has
completely turned to steam in the collector, or if the collector has been completely emptied due to
steam. The damp steam then dries quickly and is no longer able to conduct heat. Hence, it can be
assumed that these high temperature cannot occur at the measuring point of the collector sensor
(when installed in the collector tube as usual), as the remaining thermal line would cool down the
temperature via the metal connections between the absorber and the sensor.

„Step by Step“ Setup guide
The following guide might give you instructions on setting up the device, but it is of utmost
importance to read the entirety of the instruction manual – especially the chapters „Programs“ and „Operation“.
Level
1
Choose a hydraulic diagram based on the sketches of system diagrams. Mind the arrow diagram, as well as the the program exten-
sions „+1“, „+2“ and such, as far as they are specified in the diagram.
2
Choose a program based on its number. It may be feasible to use
one or more program extension such as „+1“ or „+2“ to optimize your
system‘s regulation.
3
Connect the sensors to the inputs, as well as pumps, valves etc. to
the outputs according to the chosen program. If used, connect the
data link (DL-Bus), the CAN-Bus and the control outputs.
4
Expert
Access the Expert level using the access code 64 and input your cho-
sen program‘s number under „Program settings“.
5
Technician
Setting up the priority allocation in the sub-menu Technician/Parameters/Priority ranking.
6
Technician
Enter the necessary setting values max, min, diff according to the list
of „necessary settings“ below your chosen program‘s diagram.
7
Technician Enter the time, date and summer time properties.
8
Technician If required, specify time programs under Time program.
9
Technician
Menu Manual Operation: the choices „Manual/ON“ and „Manual/OFF“
offer the possibility to set outputs to be turned permanently on or off
in order to check their connection. It‘s crucial to set the outputs back
to „Auto“ after you‘re done checking their functionality.
If the chosen program uses control outputs or if they‘ve been set up
manually, they can be set up to „Manual/ON“ (= 10V or 100% PWM)
or „Manual/OFF“ (= 0V or 0% PWM). Alternatively, you can choose a
specific voltage or PWM-percentage to be output. Don‘t forget to set
the outputs back to Auto after checking their functionality.
10
Expert
Outputs can be crossed out, if so desired. Find the option under
Crossout.
11
Expert
If you‘re not using the standard type PT1000 temperature sensors,
you must change your inputs‘ type of sensor in the Sensor menu.
12
Expert
If so desired, activate additional functions like starting function, cool-
ing function, heat meter etc.
13
Check the displayed sensor measurements on whether or not they‘re
plausible. Disconnected or incorrectly parameterized sensors display
a value of 9999,9°C.

Hydraulic diagrams
• The following functions can be activated in addition to all programs:
Pump run-on time, 0-10V or PWM outputs (if not already in use by the program), Sys-
tem function check, Heat meter, Pasteurisation (excl. building drying), Blocking protection (excl. building drying).
• The following functions only make sense when a solar panel is used in your system.
Excess temperature limiter, Frost protection, Start function, Solar priority, Cooling
function, Drainback function (only for drainback systems)
• The outputs A2, A3 and/or A5 can be logically connected (And/Or) to other outputs if
they‘re not used by your chosen program. Find the corresponding settings under Expert
level/Program settings/Assign unused outputs. Alternatively, you can simply control
them with manual settings.
• A hold circuit (= burner request using one sensor, deactivation using another) predomi-
nantly reacts to the deactivation sensor. This that, if through disadvantageous sensor
placement or choice of parameters, the conditions for both request and deactivation are
met, the deactivation holds higher priority.
The hydraulic diagrams displayed in this booklet are practical sketches. They serve to
ease the choice of the correct program, but don‘t replace or even describe the planning
of your system‘s construction. As such, we can‘t guarantee your system‘s functionality
if you imitate this booklet‘s hydraulic diagrams with your construction.

Differential control – Programs
Program 0 – Simple solar system (factory settings)
S3 only used in programs +1
Program 0: Pump A1 runs if:
• S1 is greater than threshold min1 w and S1 is greater than S2 by the difference diff1
• and S2 has not exceeded threshold max1.
A1 = S1 > (S2 + diff1) & S1 > min1 & S2 < max1
All Programs +1:
In addition, if S3 exceeds the threshold max2, pump A1 is deactivated.
All Programs +4: Simple drain-back solar system with valve
This program may only be selected if the drain-back function (Expert level/Drain-back) is ac-
tivated.
The basic settings are the same as with program 0:
A valve on output 3 prevents the heat transfer medium from flowing out of the solar panel
during the day.
Once the filling time has elapsed, the valve connected to A3 is switched on.
If the pump A1 is switched off due to the temperature difference, the valve A3 will remain
switched on for another 2 hours.
If the excess temp. limiter or frost protection are activated, the sun radiation value goes be-
low 50W/m2 (only if a radiation sensor is used) or if the low water level protection detects a
low volume flow after the filling time, the valve is closed immediately.
All Programs +1:
In addition, if S3 exceeds the threshold max2, pump A1 is deactivated.

Program 64 – Solar power system with 2 solar panels
Program 64: Pump A1 runs, if:
• S1 exceeds the threshold min1 • and S1 is greater than S3 by the difference diff1
• and S3 has not exceeded the threshold max1.
Pump A2 runs, if:
• S2 exceeds the threshold min2 • and S2 is greater than S3 by the difference diff1
• and S3 has not exceeded the threshold max1.
A1 = S1 > (S3 + diff1) & S1 > min1 & S3 < max1
A2 = S2 > (S3 + diff1) & S2 > min2 & S3 < max1
All programs +1:
If the difference between the solar panel sensors S1 and S2 exceeds the difference diff3, the
circuit with the colder solar panel is deactivated. This should, in most cases, prevent heat
from being lost on the colder solar panel as a result of temperatures mixing.
All programs +2:
Additionally, if S4 exceeds the threshold max2, pumps A1 and A2 are deactivated.
All programs +4:
Instead of two pumps, one pump A1 and a three-way valve A2 are used. If both solar circuits
are activated, circuit 2 is prioritized.
WARNING: This program is not intended for systems with two solar panels fields, since the
usage of a three-way valve always leaves one solar panel field idle.
Note: The additional application of the priority circuit „All programs +1“ is recommended.

If sensor S2 has reached the threshold max1 (or if S4 has reached the threshold max3 in con-
junction with All Programs +4), pump A2 is activated and pump A1 keeps running. This pro-
vides a cooling function with the boiler without causing idle temperatures in the solar panel.

Program 144 – Solar system with layered cylinder charging
Layered systems are only practical if the speed control is activated
(Absolute value control system: Mode „Normal“ and sensor input S1)
Program 144: The solar pumps A1 run, if:
• S1 exceeds the threshold min1 • and S1 is greater than S2 by the difference diff1
• and S2 has not exceeded the threshold max1.
The three-way valve A2 switches upwards if:
• S3 exceeds the threshold min2 • or, if S3 falls below min2, S3 is greater than S4 by the
difference diff2
• and S4 has not exceeded the threshold max2.
A1 = S1 > (S2 + diff1) & S1 > min1 & S2 < max1
A2 = (S3 > min2 or S3 > (S4 + diff2)) & S4 < max2
Program 145:
If S4 has reached the threshold max2, the rapid warm-up phase is completed and the speed
control is blocked, which achieves optimal efficiency.
If Control Output A4 is activated, the analogue level for maximum speed will be output. Con-
trol Output A5 is not affected and continues regulating.

Program 304 – Solar system with 2 collector panels + charging pump (boiler)
Program 304: Pump A1 runs, if:
• S1 exceeds the threshold min1 • and S1 is greater than S3 by the difference diff1
• and S3 has not exceeded the threshold max1.
Pump A2 runs, if:
• S2 exceeds the threshold min2 • and S2 is greater than S3 by the difference diff1
• and S3 has not exceeded the threshold max1.
The charging pump A3 runs, if:
• S4 exceeds the threshold min3 • and S4 is greater than S3 by the difference diff2
• and S3 has not exceeded the threshold max2.
A1 = S1 > (S3 + diff1) & S1 > min1 & S3 < max1
A2 = S2 > (S3 + diff1) & S2 > min2 & S3 < max1
A3 = S4 > (S3 + diff2) & S4 > min3 & S3 < max2
All programs +1: If the difference between the two solar panel sensors S1 and S2 exceeds
the difference diff3, the colder panel‘s circuit is deactivated. This prevents heat from being
lost on the colder panel when temperatures are mixed.
All programs +2: Instead of the pumps A1 and A2, one pump A1 and a three-way valve A2
are used. Without priority allocation, solar panel 2 will be preferred.
WARNING: This program is not intended for systems with two solar panels fields, since the
usage of a three-way valve always leaves one solar panel field idle.
Note: The additional application of the priority circuit „All programs +1“ is recommended.

• S1 exceeds the threshold min1 • and S1 is greater than S2 by the difference diff1
• and S2 has not exceeded the threshold max1.
The three-way valve A2 switches upwards, if:

Building drying – General Information
A special application of the universal controller UVR65 is the energy-saving and cost-effective drying
of basements and other building parts via regulation of ventilation. The special functionality of the
sensor RFS-DL (measurement of absolute humidity) enables the comparison of the values for abso-
lute humidity indoors and outdoors to turn a fan on or off.
Two humidity sensors 01/RFS-DL are required.
Basics
• The direction of the fan must have it blowing from outdoors to the inside
If the fan blows from indoors to the outside, you risk warm and humid air streaming in from adja-
cent building parts, which humidifies the room even more, rather than drying it.
• A supply fan suffices in most cases
The exhaust air is pushed out through leaks in the building. Airtight buildings must have an over-
flow opening added. If a supply fan and an exhaust fan are used, the throughput of the exhaust
fan must never exceed that of the supply fan.
• The ventilated building/room must be as airtight as possible.
In order to prevent an unwanted influx of humid air through natural circulation, windows and
doors should remain closed.
• In order to keep the resulting cooling of ventilated rooms within reasonable limits (especially in
cold seasons), timer-controlled interval operation is useful. An additional temperature monitor-
ing can be implemented.
• The exterior humidity sensor must be protected from direct insolation and rain. If necessary, it
must be physically shielded from such dangers to its functionality.
External sensors
The humidity sensors RFS-DL aren‘t usual sensors and must be con-
nected to the Dataline (DL-Bus). The chapter „Electrical connection“
explains the Dataline in further detail.
The humidity sensors are automatically parameterized as External
Sensors (Expert level) if a building drying program is input. This in-
cludes address and index of the sensors, but adjusting the exterior
sensor‘s address to 2 on the sensor itself is still necessary (as de-
scribed above).
Goals:
• Lowering of humidity through targeted ventilation with dry air
• Improvement of air quality and odor with frequent ventilation
• Replacement of energy-inefficient dehumidification devices
The RFS-DL intended to measure outdoors must have
its DL-Bus address adjusted.
Dip-switch 1 must be set to ON.
This changes the sensor‘s address to 2.

Choosing a building drying program automatically binds inputs and external sensors according to
the table below to reduce the amount of necessary manual setup. These settings can of course be
changed, if so desired.
Programs – Building drying
Program 688 – Only room drying
A room‘s humidity is to be reduced. As soon as the absolute humidity outdoors falls below the hu-
midity indoors, a fan is activated.
The fan runs, if
• the absolute humidity outdoors falls below the absolute humidity indoors and
• the optional interval operation („timer“) is active and
• the relative humidity indoors exceeds the minimal humidity min1.
A1 = S5 > min1 & S1 > (S2 + diff1)
No time programs can be set up for this program.
Program 689 – Room drying and minimum temperature monitoring
A room‘s humidity is to be reduced. If it becomes too cold in the ventilated room, the fan is deacti-
vated.
The fans runs, if
• the absolute humidity outdoors falls below the absolute humidity indoors and
• the room temperature is high enough (to prevent excessive cooling in cold seasons) and
• the optional interval operation („timer“) is active and
• the relative humidity indoors exceeds the minimum humidity min1
A1 = S5 > min1 & S1 > (S2 + diff1) & S3 > min3
No time programs can be set up for this program.

Program 690 – Room drying, minimum temperature monitoring, comfort ventilation
A room‘s humidity is to be reduced. If it becomes too cold in the ventilated room, the fan is deacti-
vated.
In order to guarantee a certain degree of air quality, the fan is activated despite exterior humidity or
if the room temperature falls below a set minimum. The fan is activated via one or more time pro-
grams, preferably in the cool morning hours, to achieve the „comfort ventilation“.
The fan runs for room drying purposes, if
• the absolute humidity outdoors falls below the absolute humidity indoors and
• the temperature is high enough (to prevent excessive cooling in cold seasons) and
• the optional interval operation („timer“) is active and
• the relative humidity indoors exceeds the minimum humidity min1.
The fan runs for comfort ventilation purposes daily, according to time programs.
A1 = S5 > min1 & S1 > (S2 + diff1) & S3 > min3 || TW(1-3)
This program has the time programs 1-3 affecting A1. Time program 1 has factory settings for 6:006:30 daily.
Program 691 – Room drying & comfort ventilation, minimal temp. monitoring for both
A room‘s humidity is to be reduced. To ensure a certain level of air quality, the fan is activated despite
exterior humidity. The fan is activated via one or more time programs, preferably in the cool morning
hours. If the set minimum room temperature is underrun, the comfort ventilation is deactivated as
well.
The fan runs for room drying purposes, if
• the absolute humidity outdoors falls below the absolute humidity indoors and
• the temperature is high enough (to prevent excessive cooling in cold seasons) and
• the optional interval operation („timer“) is active and
• the relative humidity indoors exceeds the minimum humidity min1.
The fan runs for comfort ventilation purposes daily, according to time programs, as long as the room
temperature is high enough.
A1 = S5 > min1 & S1 > (S2 + diff1) & S3 > min3 || (TW(1-3) & S3 > min 3)
This program has the time programs 1-3 affecting A1. However, if the minimum room temperature
is underrun, time program 1 will be blocked (TW1 has factory settings for 6:00-6:30 daily).

Program 692 – Room drying, room temp. monitoring, comfort ventilation, for wine cellars
A wine cellar‘s humidity is to be lowered. To ensure a certain level of air quality, the fan is activated
despite exterior humidity. The fan is activated via one or more time windows, preferably in the cool
morning hours.
The fan runs for room drying purposes, if
• the absolute humidity outdoors falls below the absolute humidity indoors and
• the relative humidity indoors exceeds 60% (for example) and
• the room temperature exceeds the desired temperature (example: 10°C) and
• the optional interval operation („timer“) is active and
• die maximum temperature indoors max1 has not been exceeded.
The fan runs for comfort ventilation purposes daily, according to the time programs, without regard
to other settings (example: 10:00 bis 10:30). Up to 3 time programs can be set up.
The time programs 1-3 affect A1 (TW1 has factory settings for 6:00-6:30 daily)
A1 = (S5 > min1 & S1 > (S2 + diff1) & S3 > min3 & S3 < max1) || TW(1-3)
All building drying programs +8 (additional dehumidifier)
Additional parameters:

Setting up time programs
Setting up a building drying program that features time programs
will cause the option „Time program Bldg drying“ to appear in the
main menu, used to parameter.
Three time programs are available, each with three adjustable
time frames. A time programs can be bound to any days of the
week. These bindings count for all of the time program‘s time
frames.
The chosen time program (and its assigned days of the week)
have a black background. To change a time frame, the wheel
must be turned until the desired value is framed in bold. Pushing
the wheel down opens a window to adjust the frame‘s time.

Heating circuit control - Programs
All heating circuit programs (except program groups 816 and 976 as well as other stated
exceptions) require the following settings:
Program 800 – Heating circuit with up to 2 heat sources
A1 = S4 > min1 & (Heating circuit = active)
A2/A3 = Mixer
If no room sensor is in use, the room influence in the menu point Expert level/Mixer must be
set to 0.0%.
Overview Technician level:
Time/Date Menu Parameters
Mode (preferably Auto) Basic parameters
Time programs Heat curve
Expert level: Set flow temp. at +10°C and at -20°C
or Slope
Menu Programming settings
Program (number) Flow temperature min and max

S2... Temperature outdoors A2... Mixer OPEN
S3... Heating circuit flow A3... Mixer CLOSE
S4... Cylinder top
S5... Boiler
Page 65
65
Program 800: Activation of heating circuit pump A1, if sensor S4 has exceeded the threshold min1. If sensor S4 is not in use, then the corresponding program setting must be adjust-
ed accordingly.
All programs +1: Like program 800, but the heating circuit pump A1 is also enabled via sen-
sor S5 and the minimum threshold min2 (2 generators for the heating circuit).
A1 = ((S4 > min) or (S5 > min2)) & (heating = active)
All programs +2: Like program 800, but the set flow temperature is output via control output
A4 (e.g. for burner modulation).
Example: The set flow temperature of 55°C is output via control output A4 as 5,5 Volt. However, the voltage being output does not fall below the threshold min1. If the pump is deacti-
vated via a shutdown condition (menu Shutdown conditions), then the control output will
output 0,5V. If it is deactivated by the shutdown condition S4 < min1, voltage equal to the
set flow temperature (as calculated by the controller) will be output, however not below the
threshold min1.
The menu Technician level/Parameters features several adjustment settings under the point
Modulation:
Offset-value for the set flow temp., range of -50,0K to +50,0K. (FS = 0,0K)
Inverse output Yes/No, FS = No
Min. output range of 0.00V - 10.00V, FS = 0.00V
Max. output range of 0.00V - 10.00V, FS = 10.00V
All programs +4: Like program 800, but the mixer control is output via control output A5 (for
mixers with 0-10V-regulation).
The menu Technician level/Parameters features adjustment settings under the point
0-10V mixer:
Inverse output Yes/No, FS = NO
Min. output range of 0.00V - 10.00V, FS = 0.00V
Max. output range of 0.00V - 10.00V, FS = 10.00V
Scaling: 0°C = 0.0 V
100°C = 10.0 V

Program 816 – Boiler circuit pump, mixer for return flow boosting
Program 816: Boiler circuit pump A1 is enabled, if S1 exceeds the threshold min1 and S4 is
greater than S2 by the difference diff1 and S2 has not exceeded the threshold max1.
A1 = S1 > min1 & S1 > (S2 + diff1) & S2 < max1
Program 817: Like program 816, however with additional 10V burner request via sensors S4
and S2 at the control output A4.
A1 = S1 > min1 & S1 > (S2 + diff1) & S2 < max1
A4 on = S4 < min3
A4 off = S2 > max3
The menu Technician level/Parameters features a setting to change the control output from
inverse no to inverse yes. The setting inverse yes has the control output generating 0 Volts,
if the threshold min3 is underrun and 10 Volts, if the threshold max3 is exceeded.
Program 818: Like program 816, but with additional 10 V burner request via sensors S4 and
S5 at the control output A5.
A1 = S1 > min1 & S1 > (S2 + diff1) & S2 < max1
A5 on = S4 < min3
A5 off = S5 > max3
The menu Technician level/Parameters features a setting to change the control output from
inverse no to inverse yes. The settings inverse yes has the control output generating 0 Volts,
if the threshold min3 is underrun and 10 Volts, if the threshold max3 is exceeded.

Installation instructions
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 sen-
sor 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).
Fundamentally, sensors should 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: 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 fit-
ting (= 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 inte-
grated 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 sec-
tion 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 center and upper third of the buffer cylinder, or positioned against the cylinder wall under-
neath the insulation.
• Pool sensor (swimming pool): Fit a T-piece 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 accu-
rately and ambient temperatures cannot falsify the result.
Page 81
81
• 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 mea-
surement 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.
• 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 replug-
ging 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.
• Outdoors temperature sensor: This sensor is installed on the coldest wall (usually fac-
ing 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.
Sensor lines
All of the sensor lines with a cross-section of 0.5mm2 can be extended up to 50m. With this
length of line and a Pt1000 temperature sensor, the measurement error is approx. +1K. Lon-
ger lines or a lower measurement error require an appropriately larger cross-section. In order
to prevent measurement fluctuations, the sensor cables must not be subject to negative ex-
ternal influences to ensure fault-free signal transmission. When using non-screened cables,
sensor cables and 230V network cables must be laid in separate cable channels and at a
minimum distance of 5 cm. If screened cables are used, the screen must be connected to
the sensor earth.

CAUTION! Always disconnect the mains plug before opening the casing!
Only work inside the controller with the power cable disconnected.
Unscrew the screws on the front and lift the cover.
The electronics are located in the cover. The connection to the terminals in the lower section
of the enclosure is made by contact pins when the cover is put in place. The lower section
can be wall mounted through the slots provided (with the cable entries in the side facing
down) or mounted on a top-hat rail (TS35 support rail as defined by the EN50022 standard).

Electrical connection
Caution: This must only be carried out by a qualified electrician in accordance with the rele-
vant local regulations. The sensor lines may not be fed through the same cable channel as
the supply voltage. The maximum load of all switching outputs A1-A3 equals 2.5A. All of the
outputs are fused along with the equipment at 3.15A. If filter pumps are directly connected,
mind their rating plate. The fuse protection can be increased to max. 5A (medium-lag). The
strip terminal PE must be used for all protective conductors.
Note: The system has to be grounded properly and furnished with surge arresters to protect
it from damage due to lightening. Sensor failures due to storms and static electricity are usu-
ally the result of faulty construction.
All sensor ground wires are internally looped and can be exchanged as needed.

Mixer drive and pumps for PWM or 0-10V signals
Programs which use outputs A4 + A5 to regulate a three-point mixer via an auxiliary relay
leave no control outputs to generate PWM or 0-10V signals for pumps. All heating circuit pro-
grams beginning at 832 are affected.
If pumps requiring PWM or 0-10V signals are in use, then they must be set to heating mode
(PWM 1). In this mode, the pump runs at full speed if it receives no control signal. Alterna-
tively, pumps requiring no control signal can be used.
If a mixer using 0-10V signals via control output A4 is in use, control output A5 is free to gen-
erate PWM or 0-10V signals for a pump. Most 0-10V mixers require external 24V supply volt-
age, which must be supplied using an external main supply unit.
The choice of the used mixer type is made in the menu point Expert level/Mixer.
Special connections
Control outputs A4 and A5 (0-10V / PWM)
These outputs are intended for the speed control of electronic pumps, to control the
burner output (0-10V or PWM) for switching tasks with an auxiliary relay (e.g. HIREL-22)
in certain programs. They can be operated via respective menu functions parallel to the
outputs A1 to A3, if they are not in use by the used program.
Sensor input S6
Compared to the other inputs, input S6 has the special feature of being able to record
fast signal changes of the type supplied by volume flow encoders (type VIG...) and wind
sensors (type WIS01).
The data lina (DL-Bus)
The bi-directional data link (DL-Bus) was developed for the UVR-controller series and is
only compatible with products of the Technische Alternative company. Any cable with a
cross section of 0.75 mm² can be used for the data link (e.g. twin-strand) with a maxi-
mum length of 30 m. For longer cables, we recommend the use of a screened cable. If
screened cables are used, the screen must be connected to the sensor earth.
CAN-Bus
The CAN-Bus serves the purpose of accessing the UVR65 controller from other devices
(and vice-versa) and for C.M.I. data logging. The basics of CAN-Bus connections are
described in further detail in the coming pages.

Sensor leads
Sensor terminal diagram
Sensors are always connected across the relevant sensor terminal (S1 – S6) and sensor earth (GND).
There is an earth strip in the base. A connection to the GND terminal must be laid using this strip be-
fore the sensors are connected.
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 con-
duits or with a minimum distance of 5 cm.
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 meters. With this lead
length and a PT1000 temperature sensor, the measuring error is approximately +1 K. A correspond-
ingly 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.

Alternatively, the auxiliary relay HIREL-22 can be used to connect a mixer to the analogue outputs A4

Data line for DL-Bus
The DL-Bus consists of just 2 wires: DL and GND (sensor earth). The DL-Bus itself supplies the nec-
essary 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 up to 30 m in length can be used as data cable. For longer
cables, we recommend the use of a screened cable.
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 for DL-Bus
Bus load of DL sensors
A 2-pole cable provides both the power supply and the signal transfer from DL-Bus sensors. An ad-
ditional power supply by means of an external power supply unit (such as with the CAN-Bus) is not
possible directly, but some DL-Bus devices can have their bus load reduced via an external 12V sup-
ply (only if explicitly stated).
Take the „BUS load“ into consideration as sensors have a relatively high current demand:
The controller UVR65 supplies a maximum 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 FTS4-
50DL can be connected to the DL BUS.

CAN-Bus network
Terminal CAN-Bus line
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 sup-
ply. 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 elec-
tromagnetic 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
The lowest possible ohm connection 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 (Single-entry-point
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..
Page 92
92
• Avoiding earth loops
If 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.

Key to symbols:
„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).

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 inter-
ference and can still carry 50 kbit/s for up to 1000 m. The CANopen recommendations (CiA DR 303-
1) for cable cross-sections are given in the table below.
The maximum cable length also depends on the number of nodes [n] linked with the BUS cable and
the cable cross-section [mm2].
Bus rate
In the CAN BUS / CAN settings menu of the UVR65, 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 crosssection 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.
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 UVR65 is 50 kbit/s. This recom-
mendation 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.

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 termina-
tion jumper again.
Example: Connection of three network nodes (NWN) with a 2x2-pole cable and termination of the ter-
minal 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 sub-
scriber (= 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.
