General information
Schematic diagram of a function module
41 different functions are stored in the controller.
Input variables are assigned to every function. The input variables of each function provide the
module with all the data required for the internal decision.
Each function can be activated or deactivated with Enable.
Within each function, data and parameter settings are utilised in order to calculate the decisions and
set values, which are then made available as output variables.
A function can therefore only perform tasks when connected by its respective input and output
variables to other parts of the system (inputs, outputs, other functions, network).
Selecting a function

General information
6
Following selection in the main menu, the functions already programmed are displayed with their
designations.
Example of functions already programmed:
Creating a new function
Select New function and then select the function type you require.
You can choose from 41 different functions and can create up to 128 functions. Functions can
also be applied multiple times.

fiD sub-menu (designation)
7
fiD sub-menu (designation)
In this sub-menu you can enter the function designation and can delete a function created previously.
Example: Analogue function
Enter the function designation by selecting a predefined designation from a general designation group
or from user defined designations.
You can also assign a number from 1 to 16 to every designation.
Deleting a function
Here you have the option of deleting the function (last menu item).
The function is not deleted until you answer a security question.
Answer by tapping either (= Yes) or (= No).

Input variables
8
Input variables
Input variables constitute the link to sensors, to output variables from other function modules, or to
other sources.
Selecting the icon will display all the input variables of the function.
Selecting an input variable will display all available sources to choose from.
•User
•Inputs
•Outputs
•Functions
•Fixed values
•System values
•DL bus
•CAN bus analogue
•CAN bus digital
After selecting the source, you can make the additional selection within the required source.
Important: For every input variable, it is important to note the input signal type:
Analogue (numeric value) or Digital (OFF/ON).
The descriptions of the function modules state the signal type for every input variable. Digital input
signals (ON/OFF) can be applied as standard or inverse.
Every function module has the Enable input variable, which represents the fundamental activation of
the entire function. It permits simple blocking or enabling of the entire module by means of a digital
signal (ON/OFF).
Certain input variables are always required for the functioning of the module and cannot be set to
unused. They appear with a dark background on the screen and are highlighted in the function
description. Other input variables can be used optionally.
Example: Depiction in the manual:

Input variables
9
If optional sensors are not used, the settings for them are shown in a different colour and their
parameters cannot be programmed.
Example: Solar control
After selecting the source, you define which information from the source is transferred to the function.
Example: CAN bus analogue
•Measurement - the value captured by the sensor
•RAS mode - the following analogue values will be issued according to the setting of the switch
on the room sensor (RAS, RASPT, RAS-PLUS, RAS-F):
Automatic 0
Standard 1
Setback 2
Standby 3
•Sensor error –digital value, ON if a sensor error occurs
•Network error –digital value, ON if a timeout is active (= error)
When linked to a function, the output variables are displayed for selection.
Use the back arrow to return to the last menu used.
Example: Enable

Input variables / System values
10
System values
The current system values are displayed in the "System values" menu.
The following system values can be selected as the source for function input variables and CAN and
DL outputs:
•General
•Time
•Date
•Sun
General system values
When programmed accordingly, these system values allow monitoring of the controller system.
•Controller start
•Sensor error inputs
•Sensor error CAN
•Sensor error DL
•Network error CAN
•Network error DL
Controller start generates a 20 second pulse 40 seconds after the device is switched on or reset,
and is used for monitoring the controller starts (e.g. after power failures) in the datalogging feature.
The interval time in datalogging should be set to 10 seconds for these starts.
The sensor errors and network errors are global digital values (No/Yes) which are not connected to
the error status of a specific sensor or network input.
If any one of the sensors or network inputs has an error, the status of the corresponding group
changes from No to Yes.
Time system values
Date system values
•Second (seconds of the current time)
•Day
•Minute (minutes of the current time)
•Month
•Hour (hour of the current time)
•Year (without the century)
•Second pulse
•Day of the week (starting with Monday)
•Minute pulse
•Calendar week
•Hour pulse
•Day of the year
•Summertime (digital value OFF/ON)
•Day pulse
•Time (hh:mm)
•Month pulse
•Year pulse
•Week pulse
The pulse values generate a single pulse per time unit.
Sun system values
•Sunrise (time)
•Sunset (time)
•Minutes until sunrise (on the same day, does not go beyond midnight)
•Minutes since sunrise
•Minutes until sunset
•Minutes since sunset (on the same day, does not go beyond midnight)
•Solar altitude (see Shading function)
•Direction of the sun (see Shading function)
•Solar altitude > 0° (digital value ON/OFF)

Parameters
11
Parameters
These parameters are values and settings which are specified by the user only.
They are settings which allow the user to adjust the controller to match the properties of the user's
system. This menu may also be divided into further sub-menus, depending on the function.
Hystereses
Many parameters have adjustable start and stop differentials which have the effect of a switching
hysteresis.
Example:
Demand temperature in the Heating demand function
Demand is triggered at T.dem. set + Diff. on (= 61 °C); shutdown is triggered at T.dem. set + Diff. off
(= 69 °C).
The values of Diff. on and Diff. off can also be negative, but are always added to the set temperature.
Example of a negative Diff value:
Here, demand is triggered at T.dem. set + Diff. on (= 51 °C); shutdown is triggered at T.dem. set +
Diff. off (= 60 °C).

Function quantities (units)
In many functions you can choose from a wide range of function quantities. These function quantities
have units with varying numbers of decimal places.
In all function calculations (exception: Curve function) the units are converted to the smallest unit in
each case (l/min to l/h, min, h and days to s, MWh to kWh, m/s to km/h, m and km to mm, mm/h and
mm/min to mm/day, m³/h and m³/min to m³/day)

Parameters
13
Some functions have buttons at the end of the parameter menu which can be used to start the
function and delete meter readings or messages.
Examples:
DHW demand, single loading start
Heat meter, start calibration, delete calibration values, delete meter reading

Output variables
14
Output variables
Output variables represent the results of the function module. They can be used to switch a hardware
output directly, or can serve as the input variables for another module, or can be linked to CAN or DL
bus outputs. A single output variable can also be linked multiple times to outputs, function input
variables and/or CAN or DL bus outputs.
The number of output variables varies greatly depending on the function.
Example: In the Comparison function there are just 3 output variables; in the Heating circuit
function there are 23.
Some output variables cannot be linked to outputs; they are identified by a different colour.
Example: Heating circuit
Controller Depiction in the manual
Important: For every output variable, it is important to note the type of variable value when linking:
Analogue (numeric value) or Digital (OFF/ON).

The values displayed are identical to the output variables of the function.
Example: Solar function
If you tap the minus sign when the function status is open, the screen will close again.

Analogue function
18
Analogue function
Standard diagram for Minimum, Maximum, Average, Sum, Filter,
Multiplexer
Function description
The Analogue function determines the highest or lowest value from the input variables, in
accordance with the standard diagram. A Multiplexer selects one of the input variables and issues
its value as the output variable. A Demultiplexer transfers the input value to a selected output
value. Simple mathematical calculations are also available in this function (Average, Sum, Filter
and Ramp).
Input variables
Enable
General enabling of the function (digital value ON/OFF)
Result (enable = off)
Analogue value for the result when Enable is OFF
Multiplexer selection
Analogue dimensionless value for selection of the input variables
(Multiplexer) or output variables (Demultiplexer)
Input variable
1 –(maximum) 10
Analogue values for the calculation as per Mode.
The number of input variables is defined in the Parameters menu or is
determined by the Mode.
➢If the Analogue function is blocked (Enable = Off), it issues a value which is either defined
by the user with Result (enable = off) or which comes from a specific source. Enable can
therefore be used to switch between analogue values.
➢If the source of an input variable is set to User, the user can specify an adjustable numeric
value.
➢Digital signals can also be processed at the inputs: If the status is OFF, then zero is applied
in the calculation as the value of that input variable; if the status is ON, then the offset
value set in the Parameters menu is applied.

Parameters for Minimum, Maximum, Average, Sum and Filter
Mode
Available for selection: Minimum, Maximum, Average, Sum and
Filter
(for explanation see below)
Function quantity
A wide range of function quantities are available, which are applied
together with their unit and their decimal places.
No. of inputs
(not shown in Filter mode)
Enter the number of input variables (maximum 10)
Output Value 1-10
(only displayed in
"Minimum" and
"Maximum" modes)
Choices: Variable + Offset, Variable + Offset = Result?
Filter time
(shown only in Filter
mode)
Enter the averaging time for calculating the average of the input
variables over time.
Offset result (enable = off)
Optional: enter an offset value for the result if Enable = OFF
Offset 1 –(maximum) 10
Optional: enter offset values for each of the input variables
Variable (enable = off)
Display of the input variable for (Enable = Off) + Offset value
Value 1 –(max.) 10
Display of the input variables + Offset values
➢The function generates the following result as the output variable by processing the input
variables (+ Offset values) via the Mode:
oMinimum: The output is the smallest value of the input variables.
oMaximum: The output is the largest value of the input variables.
oAverage: The output variable is the mathematical average (mean) of all input variables.
This allows you to take a series of measurements and calculate an average.
oSum: The output variable is formed from the sum of input variables I(1-10) according to
the following formula: sum = I1 - I2 + I3 - I4 + I5 - I6 + I7 –I8 + I9 –I10. In other words,
the variables are subtracted and added alternately.
Example: Simple addition of the two numbers I1 + I3 is produced by setting input
variable I2 to User and entering zero for I2.
oFilter: The output variable is the average over time (temporal mean) of the input
variables. The averaging time can be set. If Enable is switched off and back on again,
the averaging will start with the "Result (enable = off)" input variable.
➢Value 1 - 10: If you select Variable + Offset, you will see the respective value of the input
variables + offset shown in the output variables "Value 1 - 10".
If you have selected Variable + Offset = Result?, a digital status of ON or OFF will be displayed
in these output variables, whereby the highest or lowest value will be shown with ON and the
other values with OFF, depending on the mode (Maximum/Minimum).

➢The Multiplexer function uses the Multiplexer selection variable (+ Offset value) to select the
output variable from the input variables (+ Offset values).
Example: Number of input variables = 4
Input variable 1 = 10 °C
Input variable 2 = 20 °C
Input variable 3 = 30 °C
Input variable 4 = 40 °C
Multiplexer selection = 3
No Offset values
Result = 30 °C (= input variable 3)
➢If the value of the Multiplexer selection variable (+ Offset value) is zero or negative, the value
of input variable 1 will be issued.
➢If the value of the Multiplexer selection variable (+ Offset value) is greater than the number of
input variables, the value of the input variable with the highest ordinal number will be issued.
