• Heating/warm-water heating is carried
out continuously according to the set
value.

1.2 Set room temperature temporarily
Cover closed
The room temperature can be set tem-
porarily using the right rotary knob.
This adjustment can be made in all
operating modes except:
• Reduced heating (also in clock pro-
gramme)
• Holiday programme
• Summer operation
• Manual operation
The room temperature adjustment is no
longer valid if another operating mode is
selected or after a date change.
If the arrow in the clock pro-
gramme reaches the lowest point, re-
duced heating is activated. This
function is no longer valid if another
operating mode is selected or after
end of the heating period.
1.3 Party function/operating lock
Cover closed
Party function
Using the push button, heating can be
temporarily switched on during the re-
duction phase, the party symbol
blinks. If the party function is activated
during heating, the party symbol
appears.
When switching to reduced heating, the
party symbol blinks until the end of the
reduced heating period.
The duration of the party function is set
in setting 3:09.
The party function can be stopped at any
time by pushing the button again.
Operating lock
The active operating lock makes it im-
possible to change settings by mistake.
The operating lock is valid for all
functions
• Press the push button for 5 seconds
until all arrows to right and left of the
display are shown.
• In order to release the operating lock,
the button must be pushed again for
5 seconds until the arrows to the left
and right of the display can be seen.

1.4 Activation of the holiday programme
Cover closed
The holiday programme can be acti-
vated in two ways:
1. Select the operating mode "Holiday"
using the left rotary knob.
2. Select the automatic holiday
programme, see "2.8 Setting the
automatic holiday programme", page
17.
Active operating modes

Party function/operating lock",
page 6.
2. Select the operating mode Weekly
clock programme or Clock
programme exception day .
At the next change to reduced hea-
ting within the automatic holiday pro-
gramme, the controller returns
automatically to this setting.
If the operating mode Heating
and , is selected, it must be
changed manually back to .
A blinking symbol indicates that
another function has been selected
temporarily. 
The function of the blinking symbol/
arrow is currently active.

1.6 Activate the clock programme exception day
Cover closed 1
1. Select the operating mode Clock
programme exception day
with the left rotary knob.
If the Clock programme exception day
is set before 17.00 hrs, it is valid for the
whole day. If it is set after 17.00 hrs, it
becomes active on the following day, the
arrow stays on and blinks on
or . The operating mode
Clock programme exception day is
reset at the next change of date.
Warm-water heating is always ac-
tive parallel to heating in the selected
operating mode and starts earlier by
the set time period (setting 5:67; 
factory setting, 60 mins.).
1.7 Heating limit
Cover closed 12
1. As soon as the outside temperature
is higher than the set Heating limit
for heating (Setting 3:04), the
controller switches to Heating OFF/
Summer operation . 
The pump runs delayed to the value
in the setting 7:03. 
When the temperature drops 2 K
below the Heating limit for heating,
heating operation is switched on
again.
2. As soon as the outside temperature
has climbed above the value set for
Heating limit reduced operation
(setting 3:05), the controller swit-
ches to reduced operation mode
Heating OFF/Summer operation
. Further functions are as descri-
bed above.

1.8 Manual / emergency operation
The temperature of the boiler
thermostat must be checked before
the operating mode Manual / 
emergency operation is selected!
With floor heating, the boiler thermo-
stat temperature must not be higher
than max. 50 °C.
Cover closed 1
The operating mode Manual/emergen-
cy operation can be selected in two
ways:
1. Using the left rotary knob, select the
operating mode Manual/emergency
operation .
The clock time, day of the week
and the room temperature display will
be updated. Other data remains
unchanged.
2. Interruption of the connection
between the SR 5811and the 
VS 5511.
This can be done with a switch. In this
way, the SR 5811 is disconnected from
the electricity supply.
2
Communication between the SR 5811
and the VS 5511 plus is interrupted.
After around 60 secs., the VS 5511 plus
starts to function in Manual/emergency
operation .
• The heat generator temperature is
controlled by the boiler thermostat.
• The heating circuit pump is continu-
ally active.
• The warm-water heating function is
continually active.
• The mixer can be operated manually.
The operating mode Manual/emergen-
cy operation can fulfil two tasks:
1. During start-up by a qualified expert,
functioning of the boiler function can
be checked. 
(Heating limit exceeded ).
2. In an emergency, it allows the user a
limited heating operation with warm-
water supply. .
In an emergency, call in
a qualified expert.

3:05 Heating limit during reduced operation -10÷20 10 °C
Only in the clock programme!
If the outside temperature exceeds the set value for reduced heating operation , the heating circuit switches to summer
operation . The pump runs at a reduced rate according to the value set in 7:03. When the temperature drops to 2 K below
the set value, reduced heating operation is started again.
3:06 Preheating time (optimisation) 0÷990 0 min
This ensures that the room temperature has nearly reached the set value already at the start of the heating period.
The set value (in minutes) indicates the time difference between start of preheating and start of the heating period.
The set value is accepted 100% at temperatures of -10 °C and below; at temperatures of + 20 °C and above, to 0 %.
Recommended setting: Floor heating 240; radiator heating 180.
3:07 Room temperature influence 0÷20 4 K/K
If the measured room temperature deviates from the set value, (e.g. due to other heat sources such as sunshine), the con-
troller corrects the flow temperature by a corresponding value. The set value indicates the number of Kelvin flow temperature
correction with a room temperature deviation of 1 K.
Higher room temperature = reduced flow temperature
Lower room temperature = increased flow temperature.
0 = no compensation
1-3 = weak
4-6 = medium
7-10 = strong
11-20 = very
strong
Recommended setting: Do not set above 4 for floor heating!
3:08 Heating limit according to the flow temperature
set value -10÷10 -10 K
Summer operation becomes active when the difference between the calculated flow temperature and the room temperature
is lower then the set value.
The pump is reduced by the value given at setting 7:03.
If the difference increases to 2 K above the switch-off value, heating is started again.
