Automatic boiler for wood pellets
Instructions for installation and operation
Note
: If the boiler operates in the mode AUTO and any supply voltage failure happens, the
boiler will resume with electrical ignition programme (if the programme has been installed) after the
supply voltage delivery has been renewed.
Note
: When the boiler is being ignited for the first time, it is necessary to ensure the feeder to
be completely filled with pellets. This will be ensured by manual control of the feeder 1. The same
principle applies, if the boiler gets extinguished due to the lack of fuel.
6.7 AUTOMATIC OPERATION
It is possible to adjust by depressing the key
AUTO/MANUAL
- the script AUTO will appear on
the display unit and is also indicated by a lighting diode near the key
AUTO/MANUAL.
6.8 SELECTION OF THE REQUIRED HEAT OUTPUT OF THE BOILER
Selection of the heat output means variant adjustment of operating parameters of the boiler,
i.e. the fan, feeder on, feeder off, advance, overlap and attenuation.
The heat output of the boiler is adjusted by manufacturer (see table number 6).
6.9 ELECTRIC MODERATE HEATING
Automatic boilers
KP xx /E
for pellets are equipped with electric heating elements. This electric
moderate heating is a substitute operating mode (frost blanket measure) which makes it possible for the
user to apply moderate heating to the whole heating system, for example, if the user is absent for a long
time, if there is any failure on the boiler or in case of lack of fuel.
If the boiler is equipped with electric heating coils, the programme of the control unit will ensure
that if the heating water temperature drops under 8
°
C, a signal will be activated to control the contactor's
coil (220V 50Hz). When the heating water temperature reaches 12
°
C, the control unit will disconnect the
control voltage for the contactor. This cycle will be repeated until the temperature in the heating system
does not reach constantly higher temperature than 12
°
C.
If the boiler is equipped, upon the customer's wish, with electric heating elements of the power
input higher than 3 kW,, the boiler has to be connected to an electric system of 3x230/400V 50Hz.
