2.8.2 Installation settings
The settings for the basic operating para-
meters for individual needs are reported 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 parameteri-
sing level. Then use the same arrow buttons
to select the individual input lines and adjust
the values with

Maximum limit of delivery
temperature
Variation of the maximum speed of the
delivery temperature
Activation of adaptation
Optimisation of
switch-on time
Heating gradient
Presetting switch-off
time (00 = off)
The delivery temperature is limited to the maximum set value.
The increase per minute of the prescribed delivery temperature value sent
in °C is limited to the imposed value.
With the activation of the adaptation, the pre-set value transmitted to the
boiler regulator is adapted to the effective heat need.
The adaptation functions with both the atmospheric guide with ambient
influence and with pure ambient control.
If the "Logica Remote Control" is set as a remote control only, the adaptation
must be is deactivated.
If the switch-on time optimisation is active, the "Logica Remote Control" modi-
fies the heating gradient until it finds the optimum heating point
0 = off 1 = on
The "Logica Remote Control" selects the switch-on time such that the set
value has more or less been reached at the start of the usage time.
The more severe the night-time cooling, the earlier the heating time starts.
Example: Current ambient temperature 18.5°C
Nominal ambient temperature 20°C
Heating gradient
30 min/K
Presetting of switch-on time:
1.5 K x 30 min/K =
45 minutes
00 means that the switch-o time has not been pre-set (function disabled).
If the switch-off time optimisation is active (value > 0), the "Logica Remote
Control" modifies the pre-set time until it finds the optimum switch-off time..

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.
