the housing will be deactivated. If the controller fails to reach parameters required
for entering into the operation mode within 30 min. from activation of the fire-up
function, the „Unable to fire up“ message will appear on the display. In such a case,
the fire-up cycle needs to be restarted.
10.1.2. Operation – The operation cycle is the basic functionality of the controller.
The power of fan is regulated by the user. If the temperature rises above the set
temperature the suspension mode will be activated.
10.1.3. Suspension mode – this mode will be activated 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 controller will
switch to the damping mode. While in this mode, the fan is deactivated and the
display shows “Damping”.
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 fans (*)
-
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.
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.
