In the
Energy Statistics
menu there is also a total energy counter. This counter sums all the produced energy.
Statistics and total counter can be cleared any time. The clearing option can be found in the
Energy Statistics
menu and is available separately for the total counter and the statistics.
In order to view or clear energy counters select the "
Energy Statistics

ATTENTION ! A change in date may result in distorting the chronology of recorded events or display of incorrect energy values. For the statistics counters to work
correctly it is necessary to clear them after each date change. It is not necessary to clear the total energy yield counter after a date change

Vacation function switches on the option of
night
cooling
and
collector overheating protection
. Additionally, this option allows disabling additional heating devices
connected to the controller in the active time period declared by the user –
applies to scheme no. 3, 4, 5, 14.

Solar
collector
type
The parameter makes it possible to select solar collector type (flat or tube).
If a tube collector is selected, then between 8.00
17.00, every full hour, the collector pump is switched on for a minute. Because
of the fact that temperature sensors are located at the bottom of the collector, in case of extremely low ambient temperatures the
temperature inside the collector might deviate from the temperature indicated by the sensor. If the T1 sensor reaches a
temperature required for system operation, the P pump will continue operating
Flat / Tube
Flat
Temp. T1&T2 difference
– pump ON
This parameter defines the conditions for switching the collector pump on and off. If the T1 temperature is higher than the sum of
the “
Temp. T1&T2 difference – pump ON ”
parameter and the T2 temperature of water in the heater, the collector pump will be
switched on.

Regulation of collector’s

boiler, heater, heat pump
A parameter used in installation schemes 3, 4, 5 and 14. The controller forces additional heating devices (boiler, heater, heat
pump) to switch off once the set collector power parameter is exceeded.
In order to eliminate too frequent on/off cycles of the devices during transient insolation conditions, the controller accounts for a 5
minute delay in switch off and switch on of heating devices.
ATTENTION! Setting the value of 9900W m
akes the operation of heating devices independent from the operation of solar
collectors.

Overheat protection of
collectors
This parameter defines switch on and switch off of the option protecting solar collectors from overheating.
When switched on, P collector pump gets switched off once the collector temperature exceeds 110
C. If the collector
temperature falls below 99
C or once the T2 heater temperature “
MaxTemp. T2 OFF overheat protection”
is exceeded
the P
collector pump gets switched off. This function works even if the maximum water temperature

in the heater is exceeded.

Freezing protection of
collectors ON
The parameter is used in those countries where water serves as heat transfer fluid in solar collectors.
This parameter defines switch on and switch off of the option protecting solar collectors from freezing.
If this function is switched on, the P solar collector pump gets switched on once the temperature in the water heater as measured
by the T2 sensor is higher than 7
C, and the temperature on collectors falls below the temperature set in the
Heat transfer fluid
option. Once the temperature of water in the heater falls to 4
C or the temperature on collectors exceeds the temperature set in
the
Heat transfer fluid
option, the solar collector pump switches off.
ATTENTION! Original heat transfer fluid(with no water added) does not freeze, so it is not necessary to use the
"Protection against collector freezing” option
.
Unjustified activation of the function may result in cooling water in the heater.
Yes / No

Selection of heating
priority
This parameter defines the selection of heating priority in schemes with two heat receivers (e.g. pool).
Selecting
A > B
results in setting priority heating to the pool or additional heater. If the conditions are not suitable for heating the
pool or an additional heater, heating is switched to the solar heater. Selecting
B > A
results in setting priority heating to the solar
heater. If the conditions are not suitable for the solar heater, heating is switched to the pool or an additional heater.
Selecting
B
results in setting absolute heating priority of the solar heater. Heating will be directed to the pool or an additional
heater only after reaching preset temperature of the solar heater.
A and B letters are connected with three-way valve outlets or the name of heat receivers.
