LOGICA REMOTE CONTROL
All the boiler's functions can be managed
by a optional digital multifunctional device
code 8092204 for the remote of the boi-
ler itself and for regulating room climatic
conditions with an operational reserve of
12 hours.
The heating circuit is controlled by the room
temperature sensor built-in the equipment
or by the atmospheric conditions, with or
without environmental inflow, if the boiler is
connected to an external sensor.
Characteristics:
–Ergonomic control unit divided according
to function (control levels)).
–Clear division of basic functions:
•
operating regime, correction of set
value and presence button are directly
accessible;
•
Dif ferent real current values are
accessible through the "info" button;
•
other functions can be programmed
after the cover has been opened;
•
special service level with protected
access;
–Each setting or modification is displayed
and confirmed.
–Tome setting (special line for changing
BST/CET).
–Heating programme with max. 3 heating
periods per day, individually selectable.
– Copy function for easy transfer of hea-
ting programme to the next or pre-
vious day.
–Holiday programme: the programme is
interrupted for the holiday period and
automatically restarted on returning
home.
–Option to return the heating program to
default values.
–Programming lock (child safety).
Functions:
–Delivery temperature control guided by
the atmospheric conditions, taking into
account the dynamics of the building.
–Delivery temperature control guided by
atmospheric conditions with influence of
ambient temperature.
–Ambient temperature control only.
–Adjustable influence of ambient tempera-
ture shift .
–Switch-on and switch-off optimisation.
–Rapid lowering.
–ECO functions (daily heating limiter, auto-
matic summer/winter switch-over).
–Controllable maximum delivery tempera-
ture limit (specifically for floor plants).
–Limitation of increase in pre-set delivery
temperature.
–Anti-freeze protection for buildings.
–Hourly programming of the tank unit
temperature on two levels: comfort and
reduced.
–Domestic hot water control with nominal
value requirement and enable.
–Connection to room sensor or switching
of operating regime through the telepho-
ne system with external contact or
through a window contact.
–Anti-bacterial.
2.8.1
Installation
The unit must be installed in the main living
room. For installation, follow the assembly
instructions inserted in the package.
At this point, with the selector knob on (
),
the installer can adjust the basic parame-
ters settings according to the individual
needs (point 2.8.2).
If there is a thermostatic radiator valve
fitted, this must be set to maximum.
