Switching time periods of the
D.H.W. timer (RVA 47.320)
The settings of the switching time periods are effective if parameter
# 121 is set to 2.
The boiler temperature is kept at the nominal or reduced setpoint
value according to the pre-set time periods.
The program is then enabled/disabled by pushing the relevant but-
ton on the regulator panel.
At the input time the program will switch to the prescribed tempera-
ture values.
The table below shows at what time the prescribed values will be
activated.
Input:

00:00... 24:00 At the input time, heating at the corresponding
temperature is guaranteed.

D.H.W. preparation program (RVA 47.320)
There is the possibility of switching between three different prescri-
bed D.H.W. values, in order to attain optimum adjustment to the
D.H.W. requirement. The D.H.W. preparation can be enabled or disa-
bled using the button of the mode of operation.
a) Push the line selection button to select line 121.
b) Push the + /– buttons to select the D.H.W. preparation pro-
gram.
Setup range U/M
0...2 increment
The D.H.W. can be heated according to different timing programs,
depending on the selection you made. The D.H.W. preparation pro-
gram can work independently form the mode of operation of the
selected heating circuit.
Input values:
0 24 hours a day
1 According to the local heating programs, with one-hour advance.
2 According to D.H.W. timing program of RVA 47.320.
NOTE: The anti-freeze temperature for D.H.W. is set at 5°C and is
always active.

The D.H.W. temperature is always kept at the setpoint value of
the D.H.W. temperature, irrespective of the timer program-
ming.
– Setting value = 1: According to the local heating programs, with
one-hour advance
For the D.H.W. preparation, the selected heating program is taken
into consideration. The switching points will be set one hour in
advance, so that the actual D.H.W. temperature will be obtained
as necessary. The switching-off will occur at the same time of that
of the heating.
– Setting value = 2: According to the D.H.W. timing program
For the D.H.W. preparation, the daily program set at lines 30 ...
35 is taken into consideration. By so doing, the D.H.W. is heated
up irrespective of the heating program.
Using this program for the D.H.W. preparation you can have up to
a maximum of three heating periods a day.
