operates in priority circuit. If in the system
with DHW container the container
temperature drops down to 2°C, the
controller will alarm that it is not possible to
continue antifreeze function.
Antifreeze – parameter operation only when set
parameter Work fluid = 0.
Setting ON enables the antifreeze function.
The collector pump will be started, if the
solar work fluid temperature drops below the
parameter Antifreeze temp. The collector
pump will be stopped, if the work fluid
temperature rises above parameter
Antifreeze temp. When the function is off,
the controller will not monitor antifreeze and
it may lead to damage of the solar system in
winter period, so it is recommended that it
remains on. In scheme E, antifreeze function
operates in the circuit of container A, in
scheme F the function operates in priority
circuit.
Specific heat – parameter of work fluid
necessary for correct heat output function.
Density - density of work fluid for correct of the
energy recovered from the collector (heat
output).
Work fluid – type of fluid used in the system.
Correct setting is required for good
performance of antifreeze function and heat
output counting.

Flow P1 – flow calibration function required for
correct heat output function. Rotometer or
water meter must be installed in the sole
work fluid circuit. When edition is open
(value is blinking), the collector pump P1 will
be controlled for maximum capacity. Now,
read flow value directly from a rotometer or
measure (using water meter) how many
liters of work fluid will flow for one minute
and program the value to the controller.
Correct flow value is needed to correctly
count heat output by the controller.
Flow P2 –P2 pump calibration function for solar
scheme H. To calibrate solar work fluid
circulation speed, it is required to have
rotometer or water meter installed. When
edition is open (value is blinking), the
collector pump P2 will be controlled for
maximum capacity. Correct flow value is
needed to correctly count heat output by the
controller. Flow calibration P2 is available
only in Solar thermal scheme H.
For correct heat output counting in scheme
H, calibration for both pumps is required.
Vac. collector – vacuum collector function
on/off. The function principle of operation is
described in section 20.3.1.
Detect. level – setting that defines how much
the collector temperature must rise (at
started vacuum collector function) in one
minute, to activate the collector pump.
Operation time – time to stop the collector
pump, after the temperature set in Dect.
level is reached.
19.3.1. Vacuum collector function
Settings needed for the vacuum collector
function are described previous section.
The vacuum collector function (when
enabled) checks the collector temperature and
starts the collector pump, if after one minute the
collector temperature will increase by level set in
Detection level; the collector pump will be
started for the time set for Operation time.
After this short impulse, unless normal conditions
for starting collector pump occur, the controller
will continue checking the collector’s
temperature.
The vacuum collector function is disabled, if
the collector temperature is below 0°C and there
are alarm active that block the collector pump
operation.
19.4. Manual mode
Manual mode allows manual controlling for
outputs: P1, P2, H.
Pump P1 is controlled in such a way that the
supply terminals will be given the power supply
voltage and on the PWM terminals is generated
full signal controller.
Outputs are controlled directly after the
setting value edition is confirmed.
From this menu the controller will not return
to main screen automatically.
After you leave manual mode, the controller
returns to output controlling in accordance with
operating algorithm.
In the manual mode all automatic
actions are stopped. Leaving the
controller in this mode for longer time
may damage the system
