Application
The VRC 430f is a weather compensator controller for
heating and water heating.
"Weather compensator" means: the VRC 430f increases its heating output at lower outside temperatures
and reduces its heating output at higher outside temperatures. The outside temperature is measured by a
separate sensor, mounted outdoors, and the signal is
transmitted to the VRC 430f.
The room temperature depends only on your preset
values. The influence of the outside temperature
is compensated for.
The VRC 430f can also be used to control the following
accessory components:
– Circulation pump for the hot water generation in conjunction with a multi-functional module VR 27
– Conventional hot water cylinder
– Vaillant layer cylinder actoSTOR
– Second heating circuit using the Vaillant Mixer
Module VR 61
– Solar system using the Vaillant Solar Module VR 68
The VRC 430f can be part of a new heating and water
heating installation or can be retrofitted in an existing
installation. The appliance must have an eBUS interface.
eBUS is a communication standard for data exchange
between the components of heating technology.
You can use the VRC 430f to specify different room target temperatures according to the time and day.
In automatic mode, the VRC 430f controls your heating
based on these settings (see Fig. 0.1).
Room temperature
You can also define daily periods during which water is
heated using the VRC 430f.

Safety
The VRC 430f may only be installed by an approved
heating engineer. This person is also responsible for the
proper installation and initial start-up.
H Caution!
Risk of being scalded by hot water! When the
target temperature is above 60 °C, there is a
risk of scalding at the hot water taps. Young
children and elderly persons are particularly at
risk, even at lower temperatures.
Risk to persons should be excluded through the
selection of an appropriate target temperature
(see Section 4.7.4).
Caution!
Risk of being scalded by hot water!If your heating engineer has activated the anti-legionella
option for the hot water cylinder, the temperature of the hot water at the draw-off points
may exceed 60 °C at specific times.

When the dial is turned the values to be displayed must first be called up by the radio receiver unit. Until these values are obtained only
dashes instead of values will be displayed (--).
This generally takes up to two seconds.
Depending on the surrrounding conditions it
may take up to 15 minutes for the radio receiver to call up and display the latest data (e.g.
outside temperature, time with integrated
CDCF 77 radio signal receiver).
If dashes (--) are displayed continuously, consult your heating engineer.

target values
If you have changed a set target value — either the target room temperature or the hot water target value — in
the basc display, the new value is applied to the control
system.
When in "Manual" mode, the control uses the temporary
temperatures until either the operation mode or the

When in "Automatic" mode, the control uses the temporary temperature until the next time window starts (if
you have changed the set target value outside a time
window) or until the end of the current time window (if
you have changed the set target value within the time
window); see Fig. 4.11.

Entering timer programmes
(example for heating circuit)
Using the time programmes you can allocate up to three
time windows per day, or block of days (e.g. Mo - Fr). In
these time windows, the heating system maintains the
room temperature that you have selected, the so-called
comfort temperature. Outside the time windows, the
room temperature is set back.
h Note!
If you set the timer windows carefully to suit
your lifestyle, you will save energy without losing any heating comfort.
The next section describes how to set the timer windows using heating circuit 1 as an example. You can define time windows in a similar way for hot water and for
a circulation pump .

set-back temp
The set-back temperature is the reduced interior temperature maintained by your heating system outside of
the programmed time window.
Auto_Off (operating level for heating engineer)
The control behaviour in the Automatic operating mode
for the times in which no time windows are programmed
can be defined in screen C21 "Total system parameters"
under the menu item "Mode Auto_Off". The options are
frost protection, ECO and energy sav.
– Frost protection
In the times when no time windows are programmed
the appliance is switched off. The frost protection
function (see menu) is active.
– ECO
In the times when no time windows are programmed
the appliance is switched off. The outside temperature
is monitored. If the outside temperature falls below
3 °C, the set-back temp is applied as the room target
temperature (minimum 5 °C). This target room target
value is used for control. A set frost protection delay
time (see menu) also affects the start of this control.
If the outside temperature rises to above 4 °C, the
outside temperature monitoring remains active and
the appliance is switched off.
– Set-back
In the times when no time window is programmed, the
room target temperature is set to the set-back temp
(minimum 5 °C). This target room value is used for
control.
Operator level
Used to display and set/change the basic parameters.
The setting/ parameters can be changed by the user
without any special previous knowledge and during normal operation. The heating system can continuously
adapt to the requirements of the operator by making
the corresponding basic parameter settings.
DCF
The DCF radio receiver receives a clock signal and passes on the time to the controller. Your controller switches automatically between summer/winter time . You
only need to change the time manually if the receiver
fails to receive a signal.
Frost protection function
The frost protection function protects your heating system and apartment from frost damage. It is also active
in the "OFF" operating mode.
The frost protection function monitors the outside
temperature. If the outside temperature falls below
3 °C, the heating pump is switched on for approx.
10 min. and then off for between 10 and 60 min. (irrespective of the value of the outside temperature). If the
heating flow temperature is less than 13 °C, the burner
for the appliance is switched on and the room temperature is controlled with reference to a target value of
5 °C. If the outside temperature rises to above 4 °C, the
outside temperature monitoring remains active; the
heating pump and burner are switched off.
If the outside temperature falls to below -20 °C, the
burner for the appliance is switched on directly and the
room temperature is controlled with reference to a target value of 5 °C.
Frost protection delay time
The heating control trigger via the frost protection function (outside temperature < 3 °C) can be delayed by a
specific time period (1 - 12 hours) by specifying a frost
protection delay time (heating engineer level).
The set frost protection delay time also works in the
"ECO" function in the "Auto_Off" mode (see location).
The frost protection delay time starts when the outside
temperature falls below 3 °C.
Heating circuit (HC1)
HC1 indicates heating circuit 1. This refers to the heating
of your heating system. You can use a special
designation instead of HC1 (see operating instructions
Section 4.7.5).
Expert technician level
Used to display and set/change specific parameters.
This level is reserved exclusively for use by the heating
engineer and is therefore protected by an access code.
Operating mode
The operating modes "Auto" (automatic), "Manual" and
"OFF" exist. You can use the operating modes to specify
how you wish your room heating or water heating to be
controlled (see operating instructions, Section 4.3.2,
Table 4.2).

Heating curve
A heating curve shows the relationship between the outside temperature and the flow temperature. The selection of a heating curve allows the influencing of the flow
temperature of your heating system and therefore also
the room temperature.
The option of being able to choose from a range of
heating curves facilitates optimum adaptation of the
control to the apartment and the heating system in conjunction with the switch-on room temp. (see menu).
Fig. G.1 shows the possible heating curves for a room
target temperature of 20 °C.
If, for example, heating curve 1.5 is selected, a flow temperature of 56 °C is maintained with an outside
temperature of 0 °C.
Fig. G.1 Diagram with heating curves for a target room temperature of 20 °C
Feed temperature
in ºC
Heating flow temperature
Your appliance heats water which is pumped through
your heating system. The temperature of this hot water
as it leaves the appliance is referred to as the flow temperature.
Interior temperature
The interior temperature, also referred to as room temperature, is the actual current temperature in your
apartment.
Maximum temperature, solar cylinder
In order to ensure the highest possible returns from the
solar cylinder heating, while at the same time ensuring
that scalding/limescale protection is active, you can set
a maximum value for the solar temperature cylinder.
To do this, use the "Cylinder temp. top" SP1 sensor for
cylinder 1, if this is installed in the corresponding cylinder. Otherwise "Cylinder temp. bottom" SP2 is used.
SP3 is used for the second cylinder, swimming pool).
If the set temperature is exceeded, the solar circuit
pump is switched off. Solar power is only permitted
once the temperature on the active sensor drops 1.5 K
below the maximum temperature.
The maximum temperature for each cylinder can set
separately.
– Cylinder_Maximumtemperature_1:
20 ... 85 °C; Basic value 70 °C
– Cylinder_Maximumtemperature_2:
20 ... 85 °C; Basic value 60 °C
The programmed maximum temperature must not exceed the cylinder's maximum permisible water temperature!
Parameter
Parameters are the properties of your heating system.
You can influence these properties by altering the value
of a parameter, e.g. by reducing the value of the parameter "set-back temp" from 15 °C to 12 °C.

Axis a
Fig. G.2 Parallel heating curve offsetting
If heating curve 1.5 is selected and 22 °C rather than
20 °C is specified as the room target temperature , the
heating curve is displaced as shown in Fig. G.2. The
heating curve is displaced according to the value of the
18
room target temperature along axis a which is angled at
45°, i.e. the controller ensures a flow temperature of
67 °C with an outside temperature of 0 °C.
Switch-on room temp. (operating level for expert
technicians)
You can specify whether or not the temperature sensor
fitted in the VRC 430f should be used in screen C8 "HC1
Parameter" under the "Switch-on room temp." menu
item.
The following inputs are possible in the menu point
"Switch-on room temp.":
– None
The temperature sensor is not used for control.
– Switch on
The in-built temperature sensor measures the current

heating flow temperature is adjusted in the event of
deviation.
– Thermostat
The in-built temperature sensor measures the current
room temperature in the reference room. If the measured value is below the target room temperature the
heating flow temperature is increased and if the value
is above the target room temperature the appliance is
switched off.
The use of the switch-on room temp., in combination
with careful selection of the heating curve, leads to optimum control of the heating system.
In the case of the circulation pump the time windows
determine the operating times.
In automatic mode the system is controlled is in accordance with the specified values in the time windows.
Circulation pump
Depending on the length of the pipe, there may be a
brief delay before hot water flows when the hot water
cock is opened. A circulation pump circulates hot water
via your hot water pipe. This means that hot water is
available instantly when the water cock is opened. Time
windows can be programmed for the circulation pump.
Room target temperature
The room target temperature is the temperature that
should prevail in your apartment and is specified at the
controller. Your appliance supplies heat until the interior
temperature matches the room target temperature.
When entering time programmes the room target temperature is also referred to as the comfort temperature.
Set values
Set values are desired values that you specify in the
controller, e.g. the room target temperature or target
temperature for water heating.
Summer/Winter changeover
In the screen 1 "Basic Data" in the menu point "Mode
selection" you can determine whether the changeover
from summer to winter should take place automatically
(Selection: Auto).
The factory setting (as-supplied condition) is for automatic changeover not to take place (Selection: Off).
If the VRC 430f is equipped with the wireless outdoor
sensor VR 21 that receives the radio time signal DCF77,
the summer/winter changeover takes place automatically; it is not possible to shutdown the automatic
changeover (selection: Off) in this case.
Flow temperature
See Heating flow temperature.
Water heating
The water in the hot water cylinder is heated to the selected target temperature by the appliance. If the temperature in the hot water cylinder falls by a specific
amount the water is heated again until it reaches the
target temperature. Time windows for water heating
can be programmed.
Time window
Three time windows can be programmed per day for the
heating, water heating and circulation pump (see
operating instructions Section 4.7.1).
A target value is allocated to each time window
programmed for the heating.
In the case of water heating the hot water target temperature applies for all time windows (Screen 10 "Hot
water parameters").
