temperature a so called suspension mode will be activated.
10.1.3. Suspension mode – this mode will be activated
EN automatically if the temperature is equal or higher than the
set temperature. In that case, in order to ensure smooth
decrease of temperature of circulating water it is necessary
to properly set operation times of the fan.
10.1.4. Damping - if boiler temperature drops by 2°C below
the fire-up threshold and fails to rise above this value for 30
min. (default damping time), the controler will switch to the
damping mode. While in this mode, the fan is deactivated
and the display shows "Damping". In case of voltage loss,
the controller ceases to operate. When power is restored,
the controller returns to operation with previously set
parameters using its built-in memory.
10.2. Main page
During normal operation (in only CH mode) the LCD
display shows the main page which presents the following
information:
• Boiler temperature (on the left side of the display)
• Set temperature (on the right side of the boiler)
• Symbol of non-operating fan (
- Mode of operation - in the lower right corner appear in
capital letters initials of the respective operating mode:
D – residential heating; R – parallel pumps;
В – DHW priority; L – summer mode.
This screen allows for quick change of the set temperature,
by the means of PLUS and MINUS buttons. Pressing down
MENU moves the user to the 1st level menu, the display
then shows the first two rows of the menu. In each menu
the user can move up and down by the means of PLUS and
MINUS buttons. Pressing down MENU moves the user to the
consecutive menu or enables a specific function. EXIT moves
the user back to the root menu.
10.3. Fire-up
This function starts up the fan during fire up sequence (Fire
up - (  ) ON, (  ) OFF). If the fan is not operating, a star
*
symbol will appear in the upper right corner of the display.
This function allows the user to safely operate the boiler. If
the fan is turned on DO NOT open the boiler door. If, during
fire up sequence the boiler will not reach 40°C (default
damping threshold) during 30 min. the display will present
the following alarm:
In this case the user should restart the fire up sequence – the
thermoregulator will once again start the fire up sequence.

10.4. Manual operation

In this mode each executive element can be switched off and
on independently from all the other elements.
Pressing down MENU starts the fan, which remains turned
on until the next pressing of the MENU button

)
Pressing down MENU Turns on / off - CH PUMP.
Pressing down MENU Turns on / off WUW PUMP.
Pressing down MENU Turns on / off alarm signal.
10.5. Pumps (CH and WUW) switch on temperature
This option is used in order to set the switch on temperature
of the CH and WUW pump (it is measured in the boiler). If
the temperature increase above the set level the pumps will
switch on. The pumps will switch off after the temperature
drops below the set temperature (minus 2°С of hysteresis),
in this case the pump will switch when the temperature in
boiler drops below 33°С.
10.6. Hysteresis of the boiler
This option can be used to set the hysteresis of the set
temperature. It is the difference between the temperature
of start of the suspension mode and the temperature of
restarting the operation mode (e.g. when value of the set
temperature is 60°C and hysteresis is 2°C, the start of the
suspension mode will take place at 60°C, whereas the restart
of the operation mode will take place at 58°C. Hysteresis can
be set in the range between 2°C and 6°C.
10.7. WUW - domestic hot water - Hysteresis
This option can be used to set the value of the hysteresis of
the boiler set temperature. It is the difference between the
set temperature (that is the boiler required temperature)
and the actual boiler temperature (e.g. if the set temperature
has the value of 55°C, and the hysteresis is 5°C. After the set
temperature (55°C) is reached the WUW pump will switch
