Safety requirements:
All installation and wiring work on the controller must only be carried
out in a zero-volts state.
The opening, connection and commissioning of the device may only be
carried out by competent personnel. In so doing, all local security re-
quirements must be adhered to.
The device corresponds to the latest state of the art and fulfills all necessary safety condi-
tions. It may only be used or deployed in accordance with the technical data and the safety
conditions and rules listed below. When using the device, the legal and safety regulations
apposite to the particular use are also to be observed.
►The device must only be installed in a dry interior room.
►It must be possible to isolate the controller from the mains using an all-pole isolating de-
vice (plug/socket or double pole isolator).
►Before starting installation or wiring work, the controller must be completely isolated from
the mains voltage and protected against being switched back on. Never interchange the
safety extra-low voltage connections (sensor connections) with the 230V connections. De-
structive 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. Take
care when fitting temperature sensors!
►For safety reasons, the system 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 visu-
al damage, no longer functions or has been stored for a lengthy period of time under un-
suitable conditions. If this is the case, place the controller and equipment out of service
and secure against unintentional use.
Maintenance:
The system does not require maintenance if handled and used properly. Use a cloth mois-
tened with soft alcohol (such as spirit) to clean. Do not use cleansers and/or solvents such as
trichlorethene.
As none of the components relevant to accuracy are under loads when used properly,
they have a long service life without much drift. The unit thus does not have any adjustment
options. No adjustments are needed.
The design characteristics of the unit must not be changed during repairs. Spare parts
must correspond to the original spare parts and be as good as new.

Generally applicable rules for the proper use of this unit:
When used for floor and wall heaters: here, a safety thermostat must be used just as
with conventional heater controllers. It has to switch off the heating loop pump if there
is overheating regardless of the output from the controller to prevent indirect damage
from excess temperatures.
It is necessary to set all „Required settings“ mentioned in the hydraulic diagrams.
Relay output A4 can be made potential-free by resetting the jumpers.
All programs +1 (+2, +4, +8)" indicates that the selected program number can be in-
creased by the sum total of these numbers.
Example: Diagram 0, program 1 = pump-valve system
All programs +2: program also includes the boiler temperature T5
1+2 = 3 pump-valve system including the boiler temperature T5
Linking of outputs: Possibility to cancel out the numbered outputs listed in the pro-
gram diagram against each other (e.g. A1 with A2, A1 with A3 or A2 with A3, etc.). By
this means it is possible to assign the speed output at will. Addition of following num-
bers to the selected program number:
Linking of outputs A1 with A3 ..... +100 A1 with A4 ..... +200
A2 with A3 ..... +300 A2 with A4 ..... +400
A1 with A3 & A2 with A4 ..... +500 A3 with A4 ..... +600
Program selection
The following hydraulic diagrams are basic functions. Changes resp. additional functions are
described and defined by program numbers. The program number is the most important key
to correct function of the control system. Only by input of this number the controller knows,
which controlling business has to be done.
The program number is selected in the switch position Prog by the blue keys ab/auf
(=down/up).

Program 1: Instead of the two solar pumps, one pump and a three-way valve are used
(pump-valve system). The speed control (if activated) only operated when filling tank 1.
Without a priority allocation, tank 2 is filled by priority.
A1... common pump
A4... Valve (A4/S receives power when filling tank)
All programs +2: In program 0 the feed of tank TK1 by pump A3 is only controlled by differ-
ence TK2 T6 – TK1 T2. This program also includes the boiler temperature. When feeding
tank TK1 by pump A3 the difference boiler T5 – TK1 T2 will be considered additionally (same
setting diff3). Both min thresholds are active.
A1 = T1 > (T3 + diff1) & T3 < max1
A2 = T5 > (T4 + diff2) & T4 < max2 & T5 > min1
A3 = T6 > (T2 + diff3) & T2 < max3 & T6 > min2
or T5 > (T2 + diff3) & T2 < max3 & T5 > min1
A4 = T1 > (T4 + diff4) & T4 < max4
All programs +4: If both tanks have reached their maximum temperature due to the solar
power system, solar pump A1 and feed pump A3 are switched on (reverse cooling func-
tion). A3 ... or T3 > max1 & T6 < T3
All programs +8: If both tanks have reached their maximum temperature due to the solar
power system, solar pump A4 and feed pump A2 are switched on (reverse cooling func-
tion). A2 ... or T4 > max2 & T5 < T4
Note: If a solar pump is switched off manually, the controller works during reverse cooling
as the tank limit would be reached.
Program 12: The output A2 becomes available, if the feed function of tank TK2 is done by
the boiler controller. In this program A2 only switches with the thermostat function max2 at
T5 (e.g. burner requirement)
Program 13: Function like program 12, but with pump–valve system at the solar sector (see
program 1)
Program 14: Similar to Program 12. The burner requirement A2 switches on at min1 on T5.
Switch off appears when T2 has exceeded the threshold max2.
Program 15: Function like Program 14, but with pump–valve system in the solar system.

Program 17: Pump-valve system between TK1 und TK2. TK1 and TK2 are fed by a com-
mon pump A1 and a three-way valve A2. The speed control (if activated) only operated when
filling tank 1.
A1... common pump
A2... valve (A2/S receives power when filling tank TK2)
Program 18: Pump-valve system between TK1 und TK3.
A1... common pump
A3... valve (A3/S receives power when filling tank TK3)
Program 19: A common pump feeds all three tanks. Valve A3 switches between TK2 and
TK3 and – in series – valve A2 between TK1 and TK2. I.e. if both valves are free from ten-
sion, TK1 will be fed. The speed control (if activated) only operated when filling tank 1.
A1... common pump
A2... valve (A2/S receives power when filling tank TK2)
A3... valve (A3/S receives power when filling tank TK3)
If there is an active priority allocation, the two valves A2 and A3 are never switched on
simultaneously: when filling into tank 2, only pump A1 and valve A2 are switched on, when
filling into tank 3, only pump A1 and valve A3 are switched on.
All programs +4: A4 is only a signal contact which shows, that all tanks have reached their
max-thresholds.
All programs +8: If all tanks have reached their maximum temperature due to the solar
power system, tank TK2 will be fed regardless of max2.

Program 49: If the tank has reached its maximum temperature due to the solar power sys-
tem, solar pump A1 and feed pump A2 are switched on (reverse cooling function).
A2 ... or T4 > max1 & T5 < T4
All Programs +2: Output A4 (burner requirement) switches on when T2 falls below threshold
max4 and switches off when T3 exceeds max3. Max3 is no longer the tank limit for the
oil/gas boiler feed pump.

All Programs +8: This program enables controlling of two generators to each one consumer.
Output A4 is switched with the difference diff4 between T2 and T3 instead of burner re-
quirement. T2 is available for an additional forth generator. In this case threshold max4 oper-
ates at T3.
A1 = T1 > (T4 + diff1) & T4 < max1
A2 = T5 > (T4 + diff2) & T5 > min1 & T4 < max2
A3 = T6 > (T3 + diff3) & T6 > min2 & T3 < max3
A4 = T2 > (T3 + diff4) & T3 < max4
Program 60: The whole function offers switching of two generators to one consumer and one
generator to two consumers. Output A4 gets an additional difference function instead of
burner requirement. A4 switches, if sensor T6 is increasing min2 and is greater than T2 by
diff4 and T2 has not exceeded max4.
A1 = T1 > (T4 + diff1) & T4 < max1
A2 = T5 > (T4 + diff2) & T5 > min1 & T4 < max2

Diagram 64: Solar power system with two solar panels and two consumers
Note: Setting the time switch, the definition of the output corresponds to the actual output,
but setting the priority it corresponds to the basic function of program 64.
Program 64: Each tank is fed from each solar panel by 4 separate pumps. No feed pump
function!

A system of one pump and a three-way valve instead of two pumps can be realized by us-
ing the auxiliary output A5: Pump = A1, three-way valve = A2; the auxiliary output A5 switch-
es simultaneously with A2 the pump A1 (setting: A2o).

All Programs +1: If the difference between collector sensors T1 and T2 exceeds the differ-
ence diff3, the colder collector is switched off. This prevents heat from being lost in the cold-
er collector when temperatures are mixed.
