TECHNICAL PASSPORT INSTALLATION and OPERATION MANUAL
the pump activation temperature (set by default
to 35°C). These temperatures may, however, vary
depending on user settings. This will cause irregular
activation of the pumps. However, when both
thresholds are exceeded, the pumps will operate
simultaneously. The central heating pump runs
continuously, while the hot consumption water pump
stops after the setpoint temperature is reached in the
water heater. While in the Parallel Pumps mode, the
letter R is displayed in the bottom right corner of the
main screen.
*
ATTENTION: In this mode, a non-return
valve should be fitted to maintain different
temperatures in the water heater and in
the house.
After activation of the parallel pumps function, three
items appear on the display. Starting from the left,
these are:
Boiler Temperature (C.H.); Water Heater
Temperature (H.C.W.)
and
Setpoint Temperature
(C.H.).
9.8.4. Summer Mode
When the function is enabled, only the hot
consumption water pump is running in order to heat
water in the water heater. The pump is switched on
above a predefined activation threshold (see the
pump activation temperature function) and will run
until the setpoint temperature has been reached. The
pump will start again when the temperature drops
below the set hysteresis. In the Summer Mode, only
the setpoint temperature is set on the boiler that
heats up water for the water heater (the temperature
set for the boiler is also the temperature set for the
water heater). While in the Summer Mode, the letter
L is displayed in the bottom right corner of the main
screen.
9.9. Main Screen
This function allows you to change the view of the
main screen. The following views are available:
9.9.1. C.H. Screen
This screen displays the current and setpoint C.H.
temperatures.
By turning the knob you can change the setpoint
temperature.
After setting the appropriate value, confirm it by
pressing the encoder knob.
9.9.2. H.C.W. Screen
This screen displays the current and setpoint H.C.W.
temperatures.
By turning the knob, you can change the setpoint
H.C.W. temperature.
After setting the appropriate value, confirm it by
pressing the encoder knob.
9.9.3. Flue Gases Screen
The following items are displayed, starting from the
left:
current C.H.
temperature, current flue gases temperature and
blow power in percentages.
This view is used for monitoring current boiler
parameters.
9.10. Language
With this function, you can select the language of
your controller.
9.11. Factory Settings
The regulator has been pre-configured. However,
it should be adjusted to your individual needs. It is
possible to return to the factory settings at any time.
By enabling the Factory Settings, all existing boiler
settings will be replaced by settings made by the
manufacturer. From then on, you can again set your
own operating parameters for the boiler.
9.12. Controller protections
In order to ensure a safe and faultless operation,
the regulator has been provided with numerous
protections. In the case of an alarm, an acoustic
warning is sounded and the display shows a
corresponding message. Press the encoder to
restore the controller to operation. In the case of
the C.H. Temperature Too High alarm, wait until the
temperature drops below the alarm value.
Тermal protection.
The boiler is protected with
an additional bimetal sensor (located at the boiler
temperature sensor) that disables the fan when the
temperature exceeds the critical value:
85°C
. This is
to prevent water from boiling in the system when
the boiler has been overheated or the controller is
damaged. When the protective function is enabled
and the temperature drops to a safe value, the
sensor will automatically restart the device and the
alarm will be deactivated. If the sensor is damaged or
