1. Manual operation
For the boiler ignition it is necessary to operate manually the fuel conveyor
and ventilator. For this purpose there serve the pushbuttons 1 and 2.
Pushbutton 1 operates the ventilator, pushbutton 2 the fuel conveyor. By
pressing the relevant unit is switched on and by repeated pressing the
relevant unit is switched off. The ventilator operation is displayed by
burning line(stroke) under the ventilator symbol. Once the ventilator stops
the line goes out. The same applies to the fuel conveyor operation indication. It is indicated by a line(stroke)
under the fuel symbol. The fact that the boiler is manually operated is indicated on display by abbreviation ru
and burning stroke at the notice „manual“.
2. Fuel conveyor cycles setting
For a correct boilers function it is necessary to set an optimal proportion between the time for fuel feeding
(conveyor works) and the time for fuel afterburning (conveyor in resting stage)
a) By pressing the pushbutton 4 there appears on display the data like on
15 and it means the operation of fuel reservoir screw conveyor 15
(combustion chamber screw conveyor works parallel, but incl. after-
running). The value can be changed by pressing the pushbutton * and
entering a new digit combination like 20. Then oF 20 is alight on
display. The decision correctness must be confirmed by pushbutton *.
Confirmation o.k. must appear on display. The fuel feeding time can be set within 3 - 90 s, see tab. no.5.
b) By pressing the pushbutton 5 there appears on display the data like oF
20 and it means that the conveyor is in a resting state for 20 s. The
value can be changed by pressing the pushbutton * and entering a new
digit combination like 30. Then oF 30 is alight on display. The decision
correctness must be confirmed by pushbutton *. Confirmation o.k.
must appear on display. The after-combustion time can be set within 3 - 90 s, see tab. no.5.
3. Inhibition duration setting
If the heating water outlet temperature has exceeded the set limit the regulator will shut down the fuel feeder
and ventilator until the temperature drops below the set limit with hysteresis -3 °C. It could happen that this
time is too long and the boiler burns out. That’s why there is set the maximum shut down time so called.
inhibition duration. Once it has passed over the ventilator and fuel conveyor start up automatically within
2 minutes, independently on heating water outlet temperature. Then the regulator comes back into inhibition
status and follows the heating water outlet temperature. The circulating pump is constantly switched on. The
same can be induced by indoor thermostat once the room temperature has been exceeded. Then besides
the induction into the inhibition status there is switched off the circulating pump while keeping the 4 minutes
after-running.
By pressing the pushbutton 6 there appears on display the data like Ut 20 and it means the 20 minutes
inhibition duration. The value can be changed by pressing the pushbutton
* and entering a new digit combination like 30. Then oF 30 is alight on
display. The decision correctness must be confirmed by pushbutton *.
Confirmation o.k. must appear on display. The inhibition duration can be
set between 5 and 90 minutes. Recommended value is 30 min. If in this
regime the heating water temperature significantly rises (first of all in
summer season, when there is a minimum heat take-off from the
system), it is recommended to increase this value.
Inhibition on display is indicated by a burning point in its right lower
corner.
4. Outlet water temperature setting
The required outlet water temperature is set by means of pushbutton 3.
On display there appears the data like Pt 70 and it means the required
outlet water temperature of 70 °C. The value can be changed by pressing
the pushbutton * and entering a new digit combination like 75. Then Pt 75
is alight on display. The decision correctness must be confirmed by
pushbutton *. Confirmation o.k. must appear on display. The required
outlet water temperature can be set between 60 and 90 °C. It is
recommended to operate boiler at temperatures higher than 65 °C.
