SETTING THE D.H.W. PARAMETERS
Reduced D.H.W.
temperature value
D.H.W. filling
The hot water may be set to a reduced temperature value, such as
40°C, which is outside the comfort zone, such as 60°C (daily pro-
gramme 8).
0
= 24 hours/ day - Hot water is always available at the temperature set
with user parameter n°3.
1
= standard - Hot water according to the daily heating programme.
In the comfort areas of heating the temperature of the D.H.W. tank is
regulated to the value set with user parameter n° 3.
In the reduced areas of heating the temperature of the D.H.W. tank is
regulated to the value set with parameter n° 61 of the service level.
2
= service disconnected
3
= second daily programme (8) - Every day of the week the temperature of
the hot water is set according to programme 8. In this case there is a
single programming for all the days of the week and three time zones are
available. In the time spans set the temperature of the D.H.W. tank is
regulated according to that set in parameter n°3. In the remaining hours
the D.H.W. tank is controlled to the temperature set with parameter n°
61 the of service level.

Final user level 2
programming block
Entrance function terminal 3-4
This block (1) can be activated to display all the parameters without modif-
ying them. Pressing buttons
or
displays
“OFF”
.
WARNING:
The activation block can be deactivated temporarily by pressing buttons
and
simultaneously; a confirmation sign appears on the display. At
this point press simultaneously the buttons
and
for at least 5 seconds.
To permanently remove the activation block, set parameter 63 on 0.
The freely programmable input (terminals 3 and 4 of the socket) allows
three different functions to be activated. The parameter has the following
significance:
1
= If an external sensor is connected, the display will show the temperature
of the external sensor ( _ _ = no sensor connected, function disabled).
2
= With an external contact, it is possible to switch-over to "reduced pre-
set value of the ambient temperature".
3
= With an external contact, it is possible to switch-over to "reduced pre-set
value of the antifreeze ambient temperature" (short circuit 0 0 0 or inter-
ruption _ _ _ ). The display shows the current status of the external contact.

SERVICE VALUES
Activation of adaptation
Optimisation of
switch-on time
Heating gradient
Presetting switch-off
time (00 = off)
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.
