Bus BridgeNet®

START WIZARD

This product is compatible with Bus BridgeNet®.
Set the SYSTEM and CASCADE parameters as indicated below for
correct installation on BUS during the start phase:
• SYSTEM = NO
The product is not connected on BUS or is only connected to a
remote control.
• SYSTEM = YES Cascade = NO
The product is installed on a system on bus with other compatible
heat generators (solar heating, boiler, hybrid system or heat pump),
at least one of which is powering the BUS. In presence of a Wi-Fi
gateway on BUS (installed on remote control or on heat generator),
the heating and domestic hot water services can be managed via
a single app for smartphones.
• SYSTEM = YES Cascade = YES
The product is installed on a cascade system (max 8) for commer-
cial or collective use. After setting the CASCADE option, confirm
whether the product is the MASTER or one of the cascade SLAVES.
The BUS allows you to align all the user operating parameters on
the MASTER product with those on the SLAVE products.
The SYSTEM and CASCADE parameters affect the P33 and P34 pa-
rameters of the installer menu.
If the product is enabled to work on BUS in order
to avoid risks of a power overload, the product will
not power the BUS (P33 parameter of the installer
menu set to OFF), except for when the product is
a cascade MASTER. It is therefore necessary to
have at least another generator which powers the
BUS to complete the start phase.
When the product is installed on BUS, all the pa-
rameters for the management of domestic hot wa-
ter, its special parameters and the system param-
eters are shared with all other products, allowing
you to use just one remote control.
INSTALLATION TYPES WITH OTHER HEAT GENERATORS
1. Heat pump water heater and separate heat generator (boiler,
heat pump or hybrid system).
The products have no integration but can be managed via a single
remote control.
2. Heat pump water heater with auxiliary generator (boiler and/or
solar system) with coil.
If the system is installed with a boiler acting as a support gener-
ator, in order for the heat pump water heater to call the boiler as
opposed to the heating element via the BUS, you must set the P14
parameter to value 3 (consult INSTALLER MENU section).
Unless otherwise specified in the auxiliary generator manual, the
auxiliary generator does not read the water heater sensors; there-
fore additional sensors are required depending on the hydraulic
circuit diagram.
3. Heat pump water heater in pre-heating of combined heating
generator (boiler or combi hybrid).
In order to enable the pre-heating management on the domestic
hot water service, set the P14 parameter to 2. In this installation, the
water heater and the combi generator share the same DHW tem-
perature setting. The water heater temperature can be reduced in
pre-set time slots using the T MIN parameter or increased using
the PV SET parameter if there is a photovoltaic system.
The combi generator does not read the sensors of the water heat-
er. Additional sensors are required, depending on the hydraulic
circuit diagram.
