Principles
This manual is designed as a guide to programming directly on the device, but also provides
important information about the elements required for programming with the TAPPS 2 programming
software (functions, inputs and outputs, etc.).
Programming with TAPPS 2 is always recommended. It enables the programmer to draw (= program)
all program operations in the form of a graphical flow chart and to define parameters for them
accordingly.
Nevertheless it is important to know how to use the "programming mechanisms" on the device itself in
order to be able to make changes on site.
Example with TAPPS 2:

Principles
6
Planning basics
To ensure efficient programming, the following order must be observed:
1
A prerequisite for programming and defining parameters is an accurate hydraulic scheme.
2
Using that scheme, you must define what should be controlled and how.
3
Based on the required control functions, you must define the sensor positions and draw
them on the scheme.
4
In the next step, all sensors and outputs are assigned the required input and output
numbers.
As all the sensor inputs and outputs have different characteristics, it is not possible to simply
number them consecutively. The input and output numbers must therefore be assigned as
instructed in this manual.
5
After that, the functions are selected and their parameters are programmed.
Designations
All elements can be designated by selecting a predefined designation from various designation
groups or from the user defined designations.
You can also assign a number from 1 to 16 to every designation.
In the "General settings" menu, all user defined designations from the technician or expert level
can be created, changed or deleted globally.

Expert mode only

Principles
7
View with designations defined previously
An alphanumeric keyboard is provided for changing a designation or creating a new one.
Up to 100 different designations can be defined by the user. The maximum number of characters per
designation is 24.
Designations defined previously are available for all elements (inputs, outputs, functions, fixed values,
bus inputs and outputs).

Principles
8
General information on programming parameters
for inputs, outputs, fixed values, functions, default settings, and CAN and DL inputs
and outputs.
Every entry must be finished by selecting .
If you want to discard your entries, select .
Example:
Entering numeric values
A keypad is displayed for entering numeric values.
Example: Entering the temperature "T.room standard" in the "Heating circuit" function.
The current value is shown (example: 22.0 °C).
The top line shows the entry range (example: 0.0 –45.0 °C).
You can make entries using either the correction keys (--, -, +, ++) or the numeric keys. The
correction keys "-" and "+" change the value of the first digit to the left of the decimal point; the keys
"--" and "++" change the value of the second digit (the tens).
The arrow key shortens the value by one digit place; the key sets the value to zero.
Finish your entry with ; discard it with .
When in a submenu, select the button to return to the main menu.

Date / time / location
9
Date / time / location
The "Date" and "Time" are shown in the status line at top right.
Tapping that status field takes you to the menu for the date, time and location details.
Example:
The system value parameters are displayed first.
Time zone –01:00 means the time zone "UTC + 1 hour". UTC stands for "Universal Time
Coordinated", also known as GMT (= Greenwich Mean Time).
Summertime –"Yes" if summertime is active.
Automatic time change –If "Yes", the time will switch over automatically to summertime
according to the specifications of the European Union.
Date –The current date (dd.mm.yy).
Time –The current time

Date / time / location
10
GPS latitude –Geographical latitude according to GPS (= global positioning system)
GPS longitude –Geographical longitude according to GPS
The values for geographical latitude and longitude are used to determine the location-specific solar
data. That data can be used in functions (e.g. shading function).
The factory default settings for the GPS data are for the location of Technische Alternative in
Amaliendorf, Austria.
Next, the location-specific solar data is displayed.
Example:
Sunrise –Time
Sunset –Time
Solar altitude –Specified in ° as measured from the geometric horizon (0°),
zenith = 90°
Direction of the sun –Specified in ° as measured from the north (0°)
North = 0°
East = 90°
South = 180°
West = 270°
Power reserve
In the event of power failure, the controller has a power reserve for about 3 days for the time and
date.

Then you must use scaling to define the value range.
Example Voltage/Global radiation:
0.00 V equates to 0 W/m², 10.00 V yields 1500 W/m².

Inputs
14
Pulse input
Inputs 15 and 16 can capture pulses with max. 20 Hz and a pulse duration of at least 25 ms
(S0 pulses).
Inputs 1 –14 can capture pulses with max. 10 Hz and a pulse duration of at least 50 ms.
Select the measured variable
Wind speed
A quotient must be entered for the "Wind speed" measured variable. This is the signal frequency at
1 km/h.
Example: The WIS01 wind sensor issues one pulse (=1Hz) per second at a wind speed of 20 km/h.
Therefore the frequency at 1 km/h equals 0.05 Hz.
Setting range: 0.01 –1.00 Hz
Flow rate
A quotient must be entered for the "Flow rate" measured variable. This is the flow rate in litres per
pulse.
Setting range: 0.1 –100.0 l/pulse
Pulse
This measured variable is used as the input variable for the "Meter/Counter" function, as a pulse
counter with "Pulses" as its unit.
User defined
For the "User defined" measured variable, both the quotient and the unit must be entered.
Setting range for quotient: 0.00001 –1000.00000 units/pulse (5 decimal places)
Units: l, kW, km, m, mm, m³.
For l, mm and m³ the unit of time must be selected as well. For km and m the units of time are
predefined and cannot be changed.
Example: For the "Energy meter" function, the unit "kW" can be used. In the example above,
0.00125 kWh/pulse was selected, which equates to 800 pulses /kWh.

Inputs
15
Designation
Enter the input designation by selecting a predefined designation from various designation groups or
from the user defined designations.
Sensor type Analogue / Temperature:
General
Generator
Consumer
Line
Climate
User (user defined designations)
You can also assign a number from 1 to 16 to every designation.
Sensor correction
The option of sensor correction is available for the measured variables Temperature, Solar radiation,
Humidity and Rain. The corrected value is utilised for all calculations and displays.
Example: Pt1000 temperature sensor
Average
This setting refers to the average of the measurements over time.
Averaging over 0.3 seconds leads to extremely rapid reactions on the part of the display and the unit.
However, this can be expected to cause fluctuations of the value.
A large average value leads to inertia and is only recommended for sensors for the heat meter.
For simple measuring tasks, around 1 - 3 seconds should be selected. For hygienic domestic hot
water heating with the ultra-fast sensor, 0.3 - 0.5 seconds should be selected.

Inputs
16
Sensor check for analogue sensors
When "Sensor check" is active (setting: "Yes"), a short circuit or a lead break will automatically
generate an error message: A warning symbol is displayed in the upper status line, and the
defective sensor is shown with a red border around it in the "Inputs" menu.
Example:
Sensor error
When "Sensor check" is active, Sensor error is available as an input variable for functions: status
"No" for a sensor that is working correctly and "Yes" for a defect (short circuit or lead break). This
allows the controller to react to the failure of a sensor, for example.
In System values / General, a sensor error for all inputs is available.
If the Standard thresholds are selected, a short circuit will be indicated if the value falls below the
lower measurement limit and a lead break will be indicated if the value exceeds the upper
measurement limit.
The Standard values for temperature sensors are -9999.9 °C for a short circuit and 9999.9 °C for a
lead break. Those values are utilised in the internal calculations in the event of an error.
By selecting the thresholds and values appropriately, a fixed value can be specified for the controller
in the event of sensor failure, in order to allow a function to continue operating in emergency mode.
Example: If the temperature value falls below the threshold of -40 °C (= "Threshold value"), a value of
0.0 °C (= "Output value") is issued and displayed for that sensor (fixed hysteresis: 1.0 °C). At the
same time the "Sensor error’ status is set to "Yes".
The short circuit threshold must be defined below the lead break threshold.
Example: Sensor 12 has fallen below
-40 °C, so 0 °C is issued as the
measurement, and a sensor error is
displayed at the same time.

In the case of voltage measurements on inputs 1-6 and 9-16 (max. 3.3V), note that the internal
resistance of the voltage source must not exceed 100 ohms otherwise the accuracy will be less than
that specified in the technical data.
Voltage measurements on inputs 7 and 8: The controller's input impedance is 30 kΩ. Make sure that
the voltage never exceeds 10.5 V as this would have an extremely negative effect on the other inputs.
Resistance measurement: If the process variable is set to "Dimensionless", measurement is only
possible up to 30 kΩ. If the process variable is set to "Resistance" and the resistances being
measured are >15 kΩ, the averaging time should be increased as the values will fluctuate slightly.

The standard type used by Technische Alternative is PT1000.
KTY (2 kΩ) was the factory-fitted standard type until 2010/2011.
PT100, PT500: As these sensors are more susceptible to external interference, their sensor leads
must be screened and the Average time should be increased. Nevertheless the accuracy specified
in the technical data for PT1000 sensors cannot be guaranteed.

Outputs
18
Outputs
The controller has 16 outputs.
Tapping the outputs display in the upper status line takes you to the "Outputs" menu. Undefined
outputs are hidden.
When selected, the outputs are displayed together with their designation and their current status (see
chapter "Display on screen").
Example:

Outputs
19
Programming the parameters
Once the required output is selected, the output type can be defined.
First, you must specify the basic output type.
Output type
The following different output types exist, although they are not available for selection for all outputs:
Switching output
Output pair
0 - 10 V
PWM
Outputs 1/2, 3/4, 6/7, 8/9, 10/11, 12/13 and 14/15 as an output pair
These outputs can be used as single switching outputs or as an output pair together with the
following switching output (e.g. to control a mixer drive).
Caution
The output pairs 1/2 and 6/7 must only be used in the relay version of the UVR16x2.
The output pairs 1/2, 3/4, 6/7, 8/9 and 10/11 are available as standard. The output pairs 12/13 and
14/15 require the use of auxiliary relays (relay modules).
The mixer runtime must be entered for every output pair.
If a mixer runtime of 0 is entered, the output pair will not be utilised.
Output pairs are shown in the status line with a "+" between the output numbers.
Example: Outputs 8+9 and 10+11 have been programmed as output pairs
If two different functions act on the two outputs in the output pair simultaneously, the output with the
lower number ("OPEN" command) will be activated.
Exception: the "Message" function –if the simultaneous command comes from this function, the
output with the higher number ("CLOSE" command) will be activated.

Outputs
20
All switching outputs
A start delay and a run-on time can be defined for all switching outputs.
All outputs
Manual mode can be restricted to certain user groups (User, Technician, Expert) for all outputs.
Outputs 12 to 16 as analogue outputs
These outputs provide a voltage between 0 and 10 V, e.g. for output-dependent control of burners
(burner modulation) or speed control of electronic pumps.
The output can be issued either as a voltage (0 –10 V) or as a PWM signal.
They can be controlled by the PID function, or by other functions. The "Scaling" provides the option
of matching the analogue value of the source (with or without decimal place) to the control range of
the device being controlled.
In PWM (pulse width modulation) mode, a square wave signal is created with a voltage level of about
10 V and a frequency of 1 kHz with a variable duty factor (0 - 100 %).
If multiple functions (analogue values) act simultaneously on one analogue output, the higher
value is output.
For cases where an analogue output is activated by a digital command, an output voltage of 0.00 V
and 10.00 V (or 0.0 % –100.0 % for PWM) can be defined. Digital commands are dominant over
links with an analogue value.
The activation of the analogue output via "Dominant off" and "Digital on" is possible by means of the
following digital signals:
Example: Output value 5.00 V
Example: Output value 10.00 V
Dominant off (from messages)
Dominant on (from messages)
Manual Off
Manual On
Digital on
