3.3.3 Parameter setting
For the regulator to be able to recognize this installation you need to
set the following parameters as shown in the table.
Installation ID
– Setting mode = INSTALLER
(please refer to the "Parameter setting levels" paragraph)
Par Description
140 LPB address
148 Timer
170 H1 input management
173 Function of contact connected to H1
NOTE: In the case of non-condensation boilers, the return temperatu-
re must be raised in order to avoid the problems related to the flue
gas condensate. To do so, the OEM 22 parameter must be modified.
– Setting mode = MANUFACTURER
(please refer to the "Parameter setting levels" paragraph)
Par Description
22 Min. limit of cascade return temperature
3.3.4 Verifying the correct recognizing
To make sure the regulator has correctly recognized the installation on
the basis of the input parameters, display the "Installer" parameter on
line 53.
Installation n° 36 must appear.

3.4 HEATING INSTALLATIONS WITH ZONE
VALVES/PUMPS AND EXTERNAL BOILER (I3/I4)
Characteristics in outline:
– Cascade management of up to 4 boilers
– Continuous power modulation of the entire cascade with automa-
tic management of the switching on/off of the single modules.
– Self-adjusting to the heat requirements.
– Automatic turnover of the boiler sequence.
– Automatic Summer/Winter switching.
– Climate adjustment with external feeler.
2
– The boilers are activated only by a signal from at least one zone
1
room thermostat.
-
– The installation pump is activated only by a signal from at least
-
one zone room thermostat.
– 7-day heating program option.
– On/Off switching of sanitary hot water production through a but-
ton on the regulator.
– 7-day Managing/Programming option for sanitary hot water.
– Automatic management of the Heating/Hot water production
priority.
The components of the kit to be used are:
Code Description
RVA 47.320 Central unit for controlling boiler cascade
QAC31 External temperature feeler
QAD21 Feelers for delivery/return temperature of cascade
QAZ21 Boiler temperature feeler
–– "Albatros" jumper for configuration
–– 4 stickers for boiler numbering (kit)
–– 4 configuration resistors (kit)
NOTE: The relays for managing the heating requirement signals of the
various zones, which are shown in the wiring diagrams, are not included
in the supplied kits for cascade management.
