WALL-MOUNTING
INSTRUCTIONS
PRECAUTIONS
PRIOR TO INSTALLATION
The device is designed for wall-mounting.
Verify that all components are intact follow-
ing transport and handling, and have not
been damaged by knocks.
In case of evident damages to the product,
do not proceed with installation.
CAUTION
When drilling the wall, take care not to
damage any electrical wiring or existing
piping.
After identifying a suitable wall, be careful
not to damage any electrical wiring or exist-
ing piping and proceed as follows:
- Loosen the 6 screws on the temperature
adjuster body (Fig.1).
- Remove the cover (Fig.2).
- Position the temperature adjuster body
on the wall and mark the 4 fixing holes
(5mm)(Fig.3).
- Drill the 4 fixing holes.
- Secure the temperature adjuster body
using the wall plugs and screws provided.
- It is advisable to lay a cable tray (Fig.3a)
(which, once mounted, will conceal all
the cable outlets) near the cable outlets
on the device's body. Optimal cable tray
depth = 60 mm.
Prior to mounting the cable tray, drill
the latter in the area of the cable outlets
to facilitate insertion of the cables and
secure these with the cable clamp (Fig.
4).
- Once all the cables have been connected,
replace the cover from bottom to top
and secure it with the 6 screws so that
the bristle strip remains inside the
temperature adjuster body.
- Proceed with the initial start-up and
parameter setting of the and domestic
hot water production circuits, on the
basis of the parameter lists and system
requirements.
CAUTION
Before carrying out any work, disconnect
the power supply through the external bi-
polar switch.
ELECTRICAL CONNECTIONS
For greater safety, ask a qualified
technician to perform a thorough check of
the electrical system.
The manufacturer shall not be responsible
for any damage caused by the absence
of a suitable earthing system or by the
malfunctioning of the electricity mains
supply. Ensure that the electrical system
can provide the maximum power required
by the module (as indicated on the data
plate). Ensure that the wires have a suitable
cross-sectional area of at least 1.5 mm2.
Proper connection to an efficient earthing
system is essential for ensuring safe
operation of the device.
The power supply cable must be connected
to a 230 V-50 Hz network, while observing
the L-N poles and ensuring connection to
earth.
H05 V2V2-F
Important!
The connection to the mains must be
permanent (not using a plug) and equipped
with a bipolar switch with a contact air gap
of at least 3 mm when open.

PERIPHERALS CONNECTION
Connecting boilers to the control unit
The cascade interface PCB is used to
connect the RVS control unit to the boilers.
One cascade interface PCB must be used
for every boiler of the cascade (e.g. 3 boilers
with 3 interfaces).
A. boiler connection via BridgeNet BUS
B. RVS63 connection via LPB
C. LED
D. LED
E. micro-switches
CAUTION!
Prior to performing the electrical
connections or allocating the code,
disconnect the power supply to the boiler
and control unit.
Observe the polarities when performing
the connections.
Boiler address allocation
Every boiler communicates with the control
unit through the cascade interface PCB.
In the cascade operation (maximum 8
elements) it is necessary to allocate an
LPB (Siemens BUS) address to each boiler.
For the cascade to function properly,
a single address must be allocated to
each boiler through the corresponding
configuration of the “E” micro-switches on
the interface.
Refer to the adjacent figure for setting the
addresses.
IMPORTANT:
The identification numbers must be
entered in succession, always starting
from boiler number 1.
Diagnostics
• LEDs C and D OFF
cascade interface not connected
• LED C ON
cascade interface powered
• LED D flashing
LPB communication present
• LED D OFF
LPB communication absent
Connecting the cascade interface PCB to
the boiler
The cascade interface PCB is housed in the
boiler's instrument compartment.
Each PCB is connected to its boiler through
the Bridgenet BUS connection.
All cascade interface PCBs are connected
in parallel to the RVS control unit through
LPB.

Once all connections to the control unit
have been effected, power the cascade
and verify whether the devices are properly
detected.
(If the control unit has a separate power
supply to the boiler, first power the control
unit then the boilers).
Verifying detection of cascade interface
PCB
After effecting all the connections, it is
necessary to verify whether the boiler has
identified the interface correctly.

QAA 75 REMOTE CONTROL
The QAA 75 remote control allows for fully
managing the functions for the zone in
which it is installed, in addition to viewing
any anomalies which may occur. It can also
be used for room or climate control for
managing a heating circuit.
Positioning
The device detects the room temperature,
therefore several factors should be taken
into account when choosing an installa-
tion site. Position the device far from heat
sources (radiators, sunlight, fireplaces,
etc.) and from draughts, doorways and win-
dows which could affect the temperature
readings.
It should be installed approximately 1.5 me-
tres above the floor level.
Installation
In case of wall-mounting, sufficient space
must be left above the unit so that it can
be removed and slid back into place (Fig. 5).
Removing the unit from its base disconnects
the power supply, thus the unit stops
functioning.
The system will continue operating on the
basis of the parameters entered last.
CAUTION
Observe the polarities when performing the
connections.
Electrical connections
The low voltage and mains voltage
connections must be kept separate.
The device must be wired in conformity to
the requirements of the Class II protection
rating, namely the network and probe
cables must not pass through the same
cable tray.

Flow setpoint boost
Manifold temperature increase during
heating up of the storage cylinder.
The system takes as reference the set
storage cylinder temperature that must be
added to the present parameter
E.g.: Nominal set-point (par. 1610) = 60°C
(par. 5020) = 15°C
60 + 15 = 75°C
This means that during heating up of the
storage cylinder the manifold operates at 75°C
0 - 30°C 16°C

TEMPERATURE ADJUSTMENT CURVE
Characteristic curve
The heating curve is used to determine the
flow set-point on the basis of which the flow
temperature can be adjusted in relation to
the existing atmospheric conditions. The
heating curve can be adjusted with various
parameters, so that the device's power -
and thus the room temperature - can be
adapted to personal needs.
Heating curve slope
The slope of the heating curve determines
the flow temperature variation in relation to
the outdoor temperature.
If the room temperature varies with cool
outdoor temperatures but not with warm
temperatures, the slope must be corrected.
Increase the setting:
the flow temperature increases especially
with low outdoor temperatures.
Reduce the setting:
the flow temperature decreases especially
with low outdoor temperatures.
Heating curve displacement
The parallel displacement of the
characteristic curve modifies the flow
temperature in a uniform manner along the
entire outdoor temperature range. If the
room temperature is generally too warm
or too cold, it must be corrected through a
parallel displacement of the curve.
Curve adaptation
With the adaptation function, the
temperature adjuster
automatically adjusts the characteristic
curve to the existing conditions.
The correct slope and parallel displacement
become irrelevant.
The adaptation can only be set to active or
deactivated
To ensure correct operation, observe the
following rules:
• a room temperature probe must be
installed;
• the “Room influence” setting must range
between 1 and 99;
• in the reference room (where the room
temperature probe is installed) there should
not be any thermostatic valves for radiators
(any valves present must be fully opened).
