EN 5 DESCRIPTION OF THE APPLIANCE
5.1 Characteristics
UNIQA REVOLUTION 25 are high-performing, latest-generation, low-NOx, wall-
mounted boilers which Sime has produced for heating and domestic hot water
production. The main elements choices made by Sime for the UNIQA REVOLUTION
25boilers are: the low NOx burner combined with a copper heat exchanger,
which operates at the same time as the heat pump, for space heating, and a
rapid heat exchanger for domestic hot water (DHW) production a “type C”
combustion chamber, sealed off from the environment in which the boiler is
installed the microprocessor electronic control board, which makes the
heating and domestic hot water production system easier to manage. The
appliance has just one heating request input, which ambient thermostats or a
remote control can be connected to. In the latter case, the boiler temperature
varies on the basis of the external temperature, according to the selected
optimal climatic curve. This provides significant energy and cost savings.
Other special features of the UNIQA REVOLUTION 25 boilers are: the anti-
freeze function which activates automatically if the temperature of the water
inside the boiler falls below the threshold of the value set at parameter “PAR
10” and , if there is an external sensor, if the external temperature falls
below the threshold of the value set at parameter “PAR 11” the anti-blocking
function of the pump and diverter valve, this activates automatically every 24
hours if no request for heat has been made domestic hot water comfort
function which allows the time necessary for the hot water to become available
to be reduced and ensures that the temperature is stable screen display of
the operating and self-diagnostic parameters with error code display when the
fault occurs. This makes repair interventions easier and allows appliance
operation to be restored correctly.
5.3 Identification
The UNIQA REVOLUTION 25 boilers can be identified by means of: 1 Packaging
label: this is located on the outside of the packag-
ing and provides a code, the serial number of the boiler and the bar code 2
Energy Efficiency Label: this is positioned on the outside of the packaging to
notify the User of the level of energy savings and reduced environmental
pollution produced by the appliance 3 Technical Data Plate: this is located
inside the front panel of the boiler and provides the technical data,
appliance performance information and any other information required by law in
the country where the appliance will be used.

6.5 New installation or installation of a replacement appliance
When UNIQA REVOLUTION 25 boilers are installed on old systems or systems
requiring updating, it is recommended the installer checks that: the
connecting flue pipe is suitable for the combustion tem-
perature of the appliance, calculated and manufactured in compliance with
Standards, that it is as straight as possible, air tight, isolated, with no
obstructions or restriction and that it has appropriate condensate collection
and evacuation systems the electrical system has been manufactured in
compliance with specific Standards and by professionally qualified personnel
the fuel delivery line and the tank (LPG) comply fully with specific Standards
the expansion vessel ensures total absorption of the fluid dilation in the
system the pump flow-head performance is sufficient for the system
characteristics the system is clean, free of any sludge, deposits, de
aerated and air tight. For system cleaning, please refer to the relevant
paragraph.
mCAUTION The manufacturer declines all liability for any damage caused by an
incorrect implementation of the smoke outlet or for an excessive use of
additives.
6.6 Cleaning the system
Before installing the appliance on a newly constructed system or replacing a
heat generator on an existing system, it is important that the system is
thoroughly cleaned to remove sludge, slag, dirt, residue etc.
Before removing an old heat generator from an existing system, it is
recommended that the user: puts a descaling additive into the water system
allows the system to work with the generator active for a few
days drains the dirty water from the system and flushes the system
with clean water once or more than once. If the old generator has already been
removed or is not available, replace it with a pump to circulate water in the
system and then proceed as described above. Once cleaning operations have been
carried out and before installing the new appliance, it is recommended that a
fluid is added to the water system to protect it from corrosion and deposits.
mCAUTION For further information on the type of additive and usage, please
contact the appliance manufacturer.
Please remember that you MUST install a Y filter (not supplied with the
appliance) on the heating system return (R).
6.7 Water system treatment
When filling and restoring the system it is good practice to use water with:
aspect: clear if possible pH: 6÷8 hardness: < 25°f. If the water
characteristics are different from those indicated, it is recommended that a
safety filter is used on the water delivery pipe to retain impurities, and a
chemical treatment system to protect against possible deposits and corrosion
which could affect boiler operation.
24
EN
If the systems are only low temperature systems, it is recommended that a
product is used to prevent the development of bacteria. In any case, please
refer to and comply with the legislation and specific technical standards in

UNIQA REVOLUTION 25 boilers leave the factory specifically prearranged for G20
gas or G31. The G20 models can be converted to function with G31 using the
“specific nozzle kit” (optional) provided by Sime on request separately from
the boiler. If changing the type of gas to be used, carry out the entire “GAS
CONVERSION” phase of the appliance. The boiler must be connected to the gas
mains in full compliance with the installation standards in force in the
country where the appliance will be used. Before connecting the boiler to the
gas mains, the user must ensure that: the type of gas is correct for the
appliance the pipes are clean the gas supply pipe is the same dimension as
or greater than

(*) The losses of the roof outlet terminal at inlet include the manifold code 8091400.
mCAUTION The total maximum length is obtained by adding the length of the
inlet and outlet pipes. The total load loss is determined by the sum of the
load losses of the single accessories that make up the piping. It should not
exceed 21,0 mmH2O.
The total extension must not in any case exceed 10 m (inlet) + 10 m (outlet)
for ducts Ø 80 mm.
NOTE: for the boiler to operate correctly it is necessary that a minimum
distance of 0.50 m of the duct is respected with a 90° inlet curve.

6.12.1 External temperature sensor
The boiler is prearranged for connection to an external air temperature sensor
and can operate with a sliding temperature. This means that the delivery
temperature sent to the boiler can vary on the basis of the external
temperature depending on the climatic curve selected from those shown in the
diagram (Fig. 33). When fitting the sensor on the outside of the building,
follow the instructions provided on the packaging of the product itself.

DE 5 GERÄTEBESCHREIBUNG
5.1 Eigenschaften
UNIQA REVOLUTION 25 sind Hochleistungs-Wandheizkessel der neuesten Generation
mit geringem NOx-Ausstoß, die von der Firma Sime zum Heizen und für die
sofortige Warmwasserbereitung entwickelt wurden. Die wichtigsten planerischen
Entscheidungen, die Sime bei der Entwicklung der Heizkessel UNIQA REVOLUTION
25 getroffen hat, sind die folgenden: der Brenner mit geringem NOx-Ausstoß
sorgt in Kombination mit
einem Kupferwärmetauscher, der gleichzeitig mit der Wärmepumpe funktioniert
für die Raumheizung und in Kombination mit einem Schnellwärmetauscher für die
Erzeugung von Brauchwarmwasser (BWW) die hermetisch dichte Brennkammer, des
,,Typs C” sorgt dafür, dass der Heizkessel von der Installationsumgebung
isoliert wird die elektronische Mikroprozessorsteuerung vereinfacht die
Steuerung der Heizungsanlage und der Warmwassererzeugung. Das Gerät verfügt
über einen einzigen Eingang über den der Heizbetrieb angefordert werden kann
und an den Raumthermostate oder eine Fernbedienung angeschlossen werden
können. Im Letzten Fall hängt die Kesseltemperatur entsprechend der
eingestellten optimalen Klimakurve von der Außentemperatur ab, was zu
erheblichen Energie- und Kosteneinsparungen führt. Weitere Besonderheiten der
Heizkessel UNIQA REVOLUTION 25 sind: Frostschutzfunktion, die automatisch
aktiviert wird, wenn die Wassertemperatur im Heizkessel unter den
eingestellten Wert des Parameters ,,PAR 10″ fällt, und, bei Vorhandensein
einer externen Sonde, wenn der Messwert der externen Sonde unter den
eingestellten Wert des Parameters ,,PAR 11″ fällt Antiblockierfunktion der
Pumpe und des Abzweigventils, aktiviert sich alle 24 Stunden automatisch, wenn
keine Wärmeanfragen eingegangen sind die Funktion ,,Komfort Brauchwasser”,
die die Wartezeit bis zur Verfügbarkeit von warmem Wasser verkürzt und die
Stabilität der Temperatur garantiert Anzeige der Betriebs- und
Selbstdiagnoseparameter auf dem Display mit Anzeige der Fehlercodes bei
Auftreten einer Störung, wodurch Reparaturen und Arbeiten zur Instandsetzung
des korrekten Betriebs des Gerätes erleichtert werden.
5.2 Kontroll- und Sicherheitsvorrichtungen
Die Heizkessel UNIQA REVOLUTION 25 sind mit den folgenden Kontroll- und
Sicherheitsvorrichtungen ausgestattet: thermische Sicherheitssonde 100°C
Sicherheitsventil 3 bar Wasserdruckwandler Heizung Vorlauffühler BWW-
Fühler Kältemittel-Hochdruckregler Luftverdampfer-Einlasssonde.
dVERBOT das Gerät mit nicht funktionierenden oder abgeänderten
Sicherheitsvorrichtungen in Betrieb zu nehmen.
aACHTUNG Der Austausch der Sicherheitsvorrichtungen darf ausschließlich von
qualifiziertem Fachpersonal und mithilfe von originalen Ersatzteile von Sime
vorgenommen werden.
