Superior control
The manufacturer recommends the superior control of Siemens series RVS (RVS 43,345 + additional
modules), because for its use has been already processed the design documentation of VIADRUS.
In the case of using the superior control is necessary to do the following:
•
For electrical connection of the superior control is used the input D2 on the controller Saphir
•
The right segment of the switch S1 must be in position off
.
•
On the line P 24 of device QAA 88 select the value 2.
•
On the operating unit HMI the superior control shall be activated in Menu Boiler / Type of Requirement by
selecting the function RVS. In the Menu Boiler / RVS is signalled the current state of the superior control
(ON / OFF).
•
The boiler must remain in the status Auto (device QAA 88 – see Fig. No. 24).
•
Due to the forced exhaust of excess heat must be connected the sensor from the superior control at the
output from the boiler (see Design documents VIADRUS).
Reaction of the boiler
The boiler becomes only a source of heat in case of using the superior control. In the manufacturer the outlet
temperature of boiler was set to 70 ° C. This temperature can be changed by pressing the buttons Plus and
Minus in the range ± 15 °C (device QAA 88 - see Fig. No.24). The regimes of time, heating of water and
control of heating circuit are not active. Parameters relating to the regimes of time, heating of water and
heating of the heating circuit will not be displayed on the device QAA 88 and on the operating unit HMI and
only the setting of parameters for the boiler remains active (e.g. fan, feeder and pump of boiler).
If the requirement from the superior control is active, then the value 1 is displayed on the line P 231of the
device QAA 88.
If the requirement from the superior control is not active, then the value 0 is displayed on the line P 231of the
device QAA 88 and at the same time there is not displayed the desired outlet temperature of boiler (after
pressing the button Plus and Minus - the device QAA 88 - see. Figure 24)

IMPORTANT CAUTIONS
•
The boiler only can be used for the purpose that it is destined for.
•
The boiler can only be operated by adults who are acquainted with this operation manual. It is
not permitted to leave the children unattended by adults at the boiler being in operation.
•
The boiler is not destined for the use by persons (incl. children) whose physical, sensual or
mental disability or lack of experience and knowledge prevent them from a safe use of the
appliance unless they are supervised or if they were not instructed on the use of appliance by a
person responsible for their safety.
•
Children should be supervised in order to ensure that they do not play with the appliance.
•
If there occurs a danger of combustible vapours or gases development and penetration into
boiler room or at the works with a temporary fire or explosion risk (gluing the floorings, painting
works using the combustible paints, etc.) the boiler must be in time before these works initiation
put out of operation.
•
When transporting the fuel into the combustion space before firing check visually the volume of
fuel in the retort, don’t put your hand into the boiler furnace. There is a danger of an injury
caused by rotating worm shaft.
•
It is forbidden to use the flammable liquids for firing the VULCANUS boiler.
•
During the operation of VULCANUS boiler it is forbidden to overheat it in any way.
•
It is forbidden to put any objects made of flammable materials on the boiler and within a distance
smaller than the safe distance from it.
•
It is forbidden to keep any flammable materials within minimum 1500 mm distance from boiler
when clearing the ashes from it. The ashes must be put aside into inflammable vessels with
cover.
