Installation and service manual
General connection rules:
In the case of all connecting wires skin a
cable covering ca. 6 - 8 cm long and the
ends of veins ca. 10 mm long.
In the case of flexible wires you must
have outside or inside the appliance a
pull-relief. The vein ends must be
equipped with wire end ferrules. In the
bushing nipples on the 230V-side you
can mount PG9 screwed connections if
necessary.
Cables are inserted in the appliance
through provided holes...
All earthed wires must be fixed in binders marked with „PE“ (potential earth).
5.1 230V-connections
For 230V-connections you must follow the
following points:
i
In the case of solid electric mains the
mains voltage for the controller outside
the controller must be able to be
switched off by a switch.
In the case of electric mains with the
help of cables and shock-proof plug this
switch may be left out.
Controllers are intended for the operation in 230V /50Hz mains. The pumps to
be connected and valves must be laid
for this voltage!
i
All switch outputs (A1/A2/A3) are
230V~ closers. If potential-free contacts
are needed, appropriate accessories
are available
i
Output A1 is operated, according to an
adjustment, as a closer (rotational
speed = 100%) or in the case of the
function „Rotational speed regulation“(rotational speed < 100%) with
block-modulated output signal for the
pump P1.
i
Output A2 behaves as A1 for pump P2
in system types Type 2 and Type 4. In
system types Type 1 and Type 3 a
valve V1 switched over.
i
Output A3 is planned for cooling, thermostat or for 2nd temperature differential controller function.
All earthed wires must be connected to
binders marked with PE.
Zero wire binders (N) are electrically
connected and are not switched!

5.2 Connection temperature sensor
The appliances SOLAREG II work with precise platinum-temperature sensors type PT1000.
According to the controller type and function range you need from 2 to 4 sensors.
Installation / cabling of temperature sensors:
Mount the sensors in the provided places
in the collector and storage tank. Pay attention to a good temperature crossing
and use, if necessary, heat conducting
paste.
The wires of the temperature sensor can
be lengthened. Up to 15 m long you need
a 2 x 0,5mm² cross-section, up to 50 m 2
x 0,75 mm². In the case of long connec-

On the sensor side do not pinch the
shield but cut off and isolate it!
Temperature sensors are connected according to the layout plan. Polarity of
both veins may be ignored in the case of
temperature sensors.
Sensor wires must be laid separately
from 230V-wires.

5.2.2 Over voltage protector module
SOLAREG II is equipped with an over voltage fine protector on all sensor inputs. Additional protection measures are not necessary as a rule for internal sensors. For collector sensor an additional protection (PROZEDA sensor connecting box with over
voltage protection) is recommended. External protection elements must not contain
any additional capacitors because they may distort measurement result.

CONTROLLER
The controllers SOLAREG II contain many
functions to regulate and monitor solar system. Basically you can distinguish
FUNCTIONS
• functions for system protection and system monitoring
• additional functions.
• controller functions for charging a storage
tank
8.1 General controller functions
The controller collects the temperatures of
various measuring points and determines
the right time to charge the storage tank on
account of programmed (additional) functions and controller parameters.

8.1.2 Rotational speed regulation
Corresponding values in menu
„Basic adjustment“:
„Programming“
--Rotational speed min <100%
The solar circulation pumps on 230Voutputs A1 and A2 can be operated either
in switch-mode (two-point controller) or in a
rotational speed regulated way.
If the rotational speed regulation is activated the pump power is adjusted by a controller so that switch-on temperature differ-
ence „Storage tank dTmax“ is kept constant
as much as possible. At lower deviation of
„Storage tank dTmax“the pump is operated
with the lowest power till the switch-off wave
is reached.
8.1.3 Cooling function
Corresponding values in menu
„Basic adjustment“:
„Programming“
11 -1
--To increase the energy productivity of solar
system it may be useful to „by-pass“the solar energy at reaching a certain storage tank
temperature or to take it from the storage
tank. If the temperature of the storage tank
(Tst) goes over the temperature barrier
Tstmax – 5K (adjusted maximal storage
tank temperature – 5K), the switch output
A3 is switched on. Switching off takes place
at lower deviation of this temperature.

nd
The 2 temperature difference regulation
enables you, independently of all other control functions, to control an output according
to an adjustable temperature difference criterion. TDiff1 is the temperature of a heat
generator and TDiff2 of a heat consumer.
The output is switched on when TDiff1 >=
TDiff2 + Diff.dTmax and simultaneously
TDiff2 < Diff.Tmax. It is switched off when
TDiff1 < TDiff2 + Diff.dTmax/2 or TDiff2 >
Diff.Tmax.
For this controller function you need temperature sensor inputs for antifreezing and
thermostat function or the 3rd switch output A3. For this reason the controller functions can be only alternatively chosen.

--The function „Tube collector“is switched on
or off in menu Basic adjustments. If the
function is activated a circulation of heat
carrying medium through the collector takes
place for 30 seconds every 30 minutes. It is
necessary to be able to measure a temperature change in the collector when no
regulation-conditioned circulation has taken
place for a longer time.

it is then interpreted as an error because in
the case of normal system dimensioning
and a pump switched on such big differences cannot take place.
If the option energy productivity measurement is activated, the flow amount at the
pump switched on is checked. If for 15 minutes no flow is recognised it is evaluated as
an error.
Error message is automatically reseted after
eliminating the failure.

(see 7.5)
The function is in menu basic adjustments
switched on or off.
Glycol mixtures can decompose in certain
conditions at high temperatures. Therefore
the maximal temperature should be limited
if possible in the collector circuit.
If all storage tanks are charged up to Tmax.,
the solar circulation pump is cut off. If the
collector temperature exceeds the adjusted
value „T Kollektor max.“, the solar circulation pump is being switched on until the collector temperature is reduced by 10K. A
part of energy is given away through pipelines as a waste, the rest is charged in the
storage tank which leads to the increase of
.
the storage tank temperature over the adjusted maximal temperature. For safety reasons the function is finished when the storage tank has achieved 95°C.
If the collector temperature falls by 2K under Tst, the recooling function becomes active. The excess storage tank energy is
given away again through the collector so
that at the next charging cycle new reserves
are available again. The recooling is finished when Tst falls under the adjusted
value Tst max.
The recooling function can be switched on
only when the collector protection function
is on.
8.2.4 System protection function
The system protection function switches off
the system at the temperature exceed „T
