Glossary
Level of protection
The level of protection indicates the suitability of elec-
trical equipment for various ambient conditions and
additionally the protection of people from potential
hazards during their use.
Example:
The controller has Level of Protection IP 20. The two
digits are significant here.
The first digit indicates the protection of the equipment
from contact, e.g. with objects or body parts, which
could penetrate into dangerous areas of the equipment
(2 = objects > 12.5 mm Ø).
The second digit indicates the protection of the equip-
ment from the ingress of water (0 = no protection).
Protection class
Protection class denotes the classification and identifi-
cation of electrical equipment with reference to the
existing safety measures to prevent electric shocks.
Target values
Target values are desired values that you specify in the
controller, e.g. the room target temperature or target
cylinder temperature for water heating.
Menu
A menu displays a selection of parameters which you
can alter.
Night set back temperature
The night set back temperature is the temperature to
which your heating system reduces the room tempera-
ture outside of the programmed time window.
Operating mode
Using the operating modes you determine how your
room heating or hot water generation is controlled.
Operator level
The Operator level displays the basic parameters which
you can set/change without any special prior knowledge
during normal operation. You can adapt your heating
installation to your needs by setting the parameters
accordingly.
Parameters
Parameters are the operating values of your heating
system.
You can set these operating values by, for example,
changing the
Night set back temperature parameter
from 15 °C to 12 °C.
Room temperature
The room temperature is the temperature actually
measured in your apartment.
Selectors
The dials are buttons with which, by turning and pres-
sing, you can select menus or parameters, and alter and
save values.
Summer/Winter changeover
In the basic display it is possible to determine whether
the changeover between summer and winter time is to
take place automatically.
The default setting (as-supplied condition) is for auto-
matic changeover not to take place.
If the controller is fitted with a VRC DCF external sen-
sor, the summer/winter changeover takes place auto-
matically. Switching off the automatic changeover is not
possible in this case.
On the last weekend in March, the clock is put forward
by one hour: from 2:00 to 3:00 hrs.
On the last weekend in October, the clock is put back by
one hour: from 3:00 to 2:00 hrs.
Switch-on room temp.
Thermostatic control takes account of the room tempe-
rature when calculating the flow temperature.
Prerequisites:
There is a temperature sensor, which measures the
room temperature, fitted in the remote control or in
the wall-mounted controller.
The thermostatic control function must be activated
for each heating circuit by the heating engineer
(Menu
C2 ).
Target room temperature
The target room temperature is the temperature that
you would like in your apartment and which you specify
to your controller.If the controller is installed in the
living room, then the target room temperature for the
room in which the controller is installed applies. If the
controller is installed in the boiler, the target room tem-
perature is applied as a reference value for controlling
the flow temperature in accordance with the heating
curve.
Time window
Three time windows per day can be programmed for the
heating, the hot water generation and the
circulation pump.
Example:
Time window 1: Mon 09.00 - 12.00 hrs.
Time window 2: Mon 15.00 - 18.30 hrs.
For hot water generation, the target hot water tempera-
ture prevails for all time windows.
The time windows specify the operating times for the
circulation pump.
Weather-controlled
The outside temperature is measured by a separate
sensor which is mounted in the open air, and the results
are transmitted to the controller. At low outside tempe-
ratures the controller provides increased heating out-
put; at higher outside temperatures the heating output
is reduced.
