steady water temperature for a longer service life of
your heat exchanger (boiler). Flue gas outlet
temperature monitoring ensures reduced harmful
dust and gas emissions. The thermal energy from the
flue gases is used for heating instead of being wasted
and disposed of through the funnel.
Explanation of buttons:
- Fan
- CH - Central Heating system pump
- HCW - Hot Consumption Water Pump
- Manual mode
- Encoder knob
- Standby
EXIT
- Exit/Enter
You can change all parameters with an encoder knob.
Turning the knob allows you to select a function or
modify its value, while pressing the knob allows you
to enter the function or confirm changed values. To
leave any function, turn the knob until you reach the
EXIT position and confirm your selection by pressing
the knob.
9.1.1. Fire up
. The cycle begins when you activate the
fire up function in the controller’s menu and is active
until the central heating boiler temperature reaches
40°C (the default fire-up threshold), on condition that
the temperature does not drop below this value for 2
minutes (the default fire-up time). If these conditions
are met, the regulator will switch to the duty mode
and the manual operation symbol on the housing
will be deactivated. If the controller fails to reach
parameters required for entering into the duty mode
within 30 minutes 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.
9.1.2.
Duty
. Once the fire-up cycle is finished, the
controller enters the duty cycle. The duty cycle is
the basic functionality of the regulator. The blow is
controlled automatically using the zPID algorithm and
the temperature is close to its setpoint value. In the
user menu, fan item will appear in place of the fire-up
function. The fan can be deactivated when needed
(e.g. while feeding fuel). If the temperature rises
unexpectedly by more than 5°C over the setpoint
value, the so-called Supervision Mode is activated.
9.1.3. Supervision Mode.
The mode is activated
during the Duty Cycle if the temperature rises by
more than 5°C over the setpoint value. In such case,
the controller is switched from the PID control to
manual settings (according to parameters entered in
the Fitter’s Menu) to reduce the temperature of the
circulation water.
9.1.4.
Damping
. If boiler temperature drops by 2°C
below the fire-up threshold and fails to rise above
this value for 30 minutes (default damping time), the
regulator 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 regulator ceases to
operate. When power is restored, the controller
returns to operation with previously set parameters
using its built-in memory. Lack of voltage does not
cause the stored parameters to be lost.
9.2. Main page
During normal operation, the LCD display shows the
Main Page containing the following:
- Boiler temperature (to the left of the display).
- Setpoint temperature (to the right of the display).
- Fan stop. After manually stopping the fan while in
the duty mode, the star symbol (*) will appear in the
top right corner.
- Operation Mode. In the bottom right corner, the
corresponding letter of the operation mode is
displayed. Depending on the operation mode, the
corresponding symbol is displayed:
D
– house heating,
B
– water heater priority,
R
–
parallel pumps,
L
– summer mode.
Pressing the encoder will move you to the main
menu. The display shows two options of the menu.
To select a different option, turn the encoder knob.
9.3. Changing the central heating CH and hot
consumption water HCW setpoint temperature
In order to change the setpoint temperature of
the central heating (while in „C.H. screen“ main
view), turn the encoder knob and (after setting a
desired value) press it to confirm the change. In
order to change the setpoint temperature of the hot
consumption water (while in “H.C.W. screen” main
view), turn the encoder knob and (after setting a
desired value) press it to confirm the change.
9.4. Firing up
This function allows you to easily fire up the boiler.
After igniting the boiler, you need to activate an
automatic fire-up cycle. By selecting optimum
parameters the boiler uses the zPID function to
smoothly switch to the duty mode. If the boiler
reaches the fire-up threshold temperature, the fan
item will appear instead of the fire-up function. From
now on, the option will be used to activate/deactivate
the fan. This setting allows you to temporarily
deactivate the fan at any time, e.g.
while feeding fuel If during the fire-up cycle the boiler
does not reach 40°C within 30 minutes, (default
