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 sec-
ondary 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 en-
sured. 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 „Pro-
grams“ and „Operation“.
Level
1Choose a hydraulic diagram based on the sketches of system dia-
grams. 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.
2Choose 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.
3Connect 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.
4Expert Access the Expert level using the access code 64 and input your cho-
sen program‘s number under „Program settings“.
5Technician Setting up the priority allocation in the sub-menu Technician/Param-
eters/Priority ranking.
6Technician Enter the necessary setting values max, min, diff according to the list
of „necessary settings“ below your chosen program‘s diagram.
7Technician Enter the time, date and summer time properties.
8Technician If required, specify time programs under Time program.
9Technician
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.

11
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 protec-
tion (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

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.

The charging pump A2 runs, if:
•S3 exceeds the threshold min2 • and S3 is greater than S2 by the difference diff2
• and S2 has not exceeded the threshold max2.
A1 = S1 > (S2 + diff1) & S1 > min1 & S2 < max1
A2 = S3 > (S2 + diff2) & S3 > min2 & S2 < max2
All programs +2:
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.
All programs +4:
Additionally, if S4 exceeds the threshold max3, pump A1 is switched off.
All programs +8:
If the re-cooling function (all programs +2) is activated, A3 runs concurrently.

Additionally, the charging pump A2 is also regulated via the heater boiler temperature S1.
Pump A2 runs, if:
•S1 exceeds the threshold min1 • and S1 is greater than S4 by the difference diff3

Program 128 – Burner request and solar system (or charging pump)
Program 128: Pump A1 runs, if:
•S1 exceeds the threshold min1 • and S1 is greater than S2 by the difference diff1
• and S2 has not exceeded the threshold max1.
Output A3 is activated, if S4 falls below the threshold min3.
Output A3 is deactivated (dominantly), if S3 exceeds the threshold max3.
A1 = S1 > (S2 + diff1) & S1 > min1 & S2 < max1
A3 (on) = S4 <min3 A3 (off) = S3 > max3
All programs +1: The burner request (A3) is regulated only via S4.
Output A3 switches on, if S4 falls below the threshold min3.
Output A3 switches off (dominantly), if S4 exceeds the threshold max3.
A3 (on) = S4 < min3 A3 (off) = S4 > max3
All programs +2:
Additionally, pump A1 switches between sensors S4 and S2, if the difference diff2 is
reached (for applications such as a boiler-buffer-cylinder system).
Pump A1 runs, if:
•S1 exceeds the threshold min1 • and S1 is greater than S2 by the difference diff1
• and S2 has not exceeded the threshold max1,
or
•S4 has exceeded the threshold min2 • and S4 is greater than S2 by the difference diff2
• and S2 has not exceeded the threshold max1.
A1 = (S1 > (S2 + diff1) & S1 > min1 & S2 < max1)

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.
