LOGICA REMOTE CONTROL
USED WITH SINGLE BOILERS.
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 fer ent r eal curr ent values ar e
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 restar ted 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 sys t em wit h ext ernal cont act 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 parameters set-
tings according to the individual needs (point
2.8.2).
The radiators in the room that the Logica is
fitted must not have thermostatic valves.
2.8.2
Installation settings
The settings for the basic operating para-
meters for individual needs are shown in
the instruction leaflet supplied with the
"Logica Remote Control" and in the section
reserved for the user in this manual.
For further adjustments which can be car-
ried out by the installer, the "Logica Remote
Control" offers a level of service and para-
meterising which can only be accessed
through a special combination of buttons.
To activate this level of service or parame-
terising press buttons
and
least 5
seconds.
This will activate the parameterising level.
Then use the same arrow buttons to select
the individual input lines and adjust the
values with
or
.
Antifreeze protection
"Pre-set ambient
temperature value"
Summer/Winter switch-over
temperature
Type of control:
0 = with ambient influence
1 = without ambient influence
Influence of ambient temperature
Heating takes place up to this pre-set value if the plant is activated in standby
(e.g. holidays).
In this way, the building antifreeze function is active, preventing an excessive
lowering of the ambient.
This parameter regulates the temperature of the automatic summer/win-
ter switch-over.
This parameter de-activates the ambient influence and as a result all the
optimisations and adaptations.
If a valid external temperature is not transmitted , the controller switches to
the pure ambient control guide variable.
If the ambient controller is used only as a remote control (placed in the refe-
rence room and without an external sensor connected), the value must be
set at 0 (zero).
If the change in ambient temperature from the pre-set value remains high
during the entire day, the influence must be increased. If the ambient tem-
perature is around the pre-set value (control oscillation), the influence must
be reduced.
Note: If the ambient temperature influence constant is set at 0, the adap-
tation of the heating curve is deactivated. In this case, parameter 57 will
have no effect at all.
