Introduction
Introduction
The RC30 makes it easy to operate your Buderus heating system
and forms part of the Energy Management System (EMS). The
heating system is controlled in such a way that you benefit from
optimum heating comfort and minimum energy consumption.
The RC30 is factory-preset. You can adjust these settings, such as
the heating program for example, and match them to your
requirements.
Special functions help you to save energy, without sacrificing your
personal comfort.
Your heating system offers a wealth of other useful functions,
including automatic summer/winter changeover and a holiday
function.
Function modules (accessories)
These instructions also apply to the RC30 used in conjunction with
the mixer module MM10 and low loss header module WM10 (see
also page 9). These function modules are set up by your installer
and do not need to be modified.
This device meets all requirements of applicable standards and
guidelines.
Conformity has been verified. All associated documents and the
declaration of conformity are available from the manufacturer.
We reserve the right to make any changes due to technical modifications.

What you should know about your heating system
2.1
How does the RC30 work?
The RC30 ensures comfortable heat and economical consumption
of fuel and electricity. It switches the boiler and pumps ON if DHW
(domestic hot water) or a higher room temperature are required.
Modern heating control units calculate the temperature required
within the boiler (the so-called flow temperature) subject to the
outside temperature and the desired room temperature (set
temperature). The relationship between the outside temperature
and the flow temperature is described as the heating curve. The
lower the outside temperature, the higher the flow temperature
must be to achieve the required room temperature.
For example, if you increase the set room temperature by 2 °C, the
heating curve is raised in parallel. This increases the flow
temperature by around 6 Kelvin (one Kelvin corresponds to one
degree Celsius).
Flow temperature in °C
The gradient of the heating curve depends on the type of heating
system (e.g. radiators or underfloor heating). This will be
determined by your installer during the commissioning process.

2.2
What you should know about your heating system
Control modes for the RC30
The RC30 can operate in three control modes:
–
outside temperature dependent control
–
room temperature control or
–
outside temperature control with room temperature influence
Outside temperature dependent control
With outside temperature dependent control, only the outside
temperature measured by the outside temperature sensor is taken
into account for the flow temperature level. The advantage of
outside temperature dependent control is that the overall heat
requirement of the house is considered, rather than the
temperature in a single reference room where the thermostat is
located. Room temperature fluctuations through solar gain,
occupants, open fireplaces or similar external heat sources are
then ignored.
If you use this type of control, adjust the thermostatic radiator
valves so that the required room temperature is obtained in each
room.
Room temperature control*)
A further possible RC30 method is room temperature control. The
RC30 calculates the temperature required inside the boiler or the
output required from the boiler, subject to the set and the actual
room temperature.
To be able to utilise the room temperature control, you require a
room which is representative of your whole home. All factors
influencing the temperature in this "reference room" – in which the
RC30 is located – will also apply to all other rooms. Not every
home has a room which meets these requirements. A pure room
temperature control has, in such cases, certain limitations.
Should you, for example, open a window in the room where the
room temperature is measured, the control unit will "think" that you
have opened the windows in all rooms in your home and will begin
to heat more vigorously.
*) Please note that the RC30 has to be located in the reference room and not in the boiler for this
option
We reserve the right to make any changes due to technical modifications.

Or conversely: You measure the temperature in a south-facing
room with different heat sources (solar or other heating sources,
e.g. an open fireplace). Now the control unit "thinks" that it is as hot
in all rooms as in the reference room; consequently the boiler
output will be severely cut back so that, for example, the northfacing rooms are too cold.
With this kind of control you will need to keep all thermostatic
radiator valves in the reference room fully open.
Outside temperature dependent control with room
temperature influence *)
The outside temperature dependent control with room temperature
influence combines the advantages of both above control modes.
The required flow temperature, which is mainly subject to the
outside temperature, can be adjusted by the room temperature
only to a limited degree. This achieves an improved maintenance
of the room temperature within the room containing the RC30,
without fully ignoring the other rooms.
With this kind of control you will also need to keep all thermostatic
radiator valves in the reference room fully open.
2.3
Why do the thermostatic radiator valves have to stay fully open?
For example, if you want to reduce the room temperature in the
reference room and you close the thermostatic valve, the flow rate
through the radiator will be reduced and, therefore, less heat is
transferred to the room. This reduces the room temperature. The
RC30 unit will endeavour to counteract the falling room
temperature by raising the flow temperature. However, raising the
flow temperature will not raise the room temperature, as the
thermostatic valve continues to limit the room temperature.
A flow temperature which is too high results in unnecessary heat
losses in boiler and pipework. At the same time, the temperature
in all other rooms without thermostatic valves increases due to the
higher boiler water temperature.
*) Please note that the RC30 has to be located in the reference room and not in the boiler for this
option
We reserve the right to make any changes due to technical modifications.

What you should know about your heating system
Why do I need a heating program?
Unlike standard controls, the RC30 offers more choice than just
ON/OFF. Modern heating systems offer a choice of heating
programs. A heating program sets the times at which the system
automatically switches between two different room temperatures.
The first setting, called „day mode“, is for when the building is
actively occupied and a higher temperature is required. The
second setting, called „night mode“ is not just for the night but for
any time when you want to maintain a lower temperature i. e. when
the building is unoccupied or when everyone is in bed at night. This
enables you to set a reduced room temperature at night or at other
times when a reduced temperature is sufficient (also known as
"night setback"). You can save a lot of energy by choosing a
heating program to match your lifestyle.
The RC30 offers four options on "night mode" for reducing the
room temperature. Your installer will select and set up one of these
options according to your requirements:
–
"OUTSIDE STOP" (also possible without remote control,
outside sensor required)
"Outside stop" switches the heating circuit according to the
outside temperature and the set frost protection temperature
(see Chapter 5.8.10 "Frost protection", page 39).
Above the frost protection temperature the heating circuit is
switched off. Below this temperature the system heats to the
set night mode temperature.
–
- "ROOM STOP" (only possible with RC30 in reference room)
"Room stop" switches the heating circuit according to the room
temperature.
Above the set room temperature the heating circuit is switched
off. Below the set room temperature the system heats to the set
night mode temperature. This function requires the RC30 to be
located in the reference room.
–
"STANDBY" (also possible without remote control)
Here the heating circuit is simply turned off in night mode. You
must activate frost protection monitoring (see Chapter 5.8.9
"Frost protection type", page 38).
We reserve the right to make any changes due to technical modifications.

2
- "REDUCED" (also possible without remote control)
Here the system heats to the set night temperature in setback
heating mode.
The heating circuit pumps operate constantly.
The heating program is only switched on in automatic mode; night
setback is not available in manual mode.
2.5
What are heating circuits?
A heating circuit describes the circuit taken by the heating water
from the boiler via the radiators and back to the boiler (Fig. 1 on
page 5). Several heating circuits may be connected to one boiler,
for example one heating circuit for supplying radiators and a further
heating circuit for supplying an underfloor heating system. In this
case, the radiators are supplied at a higher flow temperature than
the underfloor heating system.
With the RC30 you can operate and control the two heating circuits
independently (Fig. 2, Item 1). If the second heating circuit is used
to supply a separate flat or area of the building, a separate room
controller RC20 can also be installed (Fig. 2, Item 2). This allows
you to operate the second heating circuit as an "independent"
system.

What you should know about your heating system
Mixer module MM10
The supply of different flow temperatures to different heating
circuits in a heating system can only be achieved if a three-way
mixing valve is installed between the boiler and the second heating
circuit. This valve is controlled by the mixer module MM10
(accessory). Using an additional temperature sensor in the flow of
the heating circuit to be supplied, sufficient cold return water is
added to the hot flow water via the three-way mixing valve to
achieve the required lower temperature.
Low loss header module WM10
It is important to note that heating circuits with three-way mixing
valves require an additional pump. This pump enables the second
heating circuit to be operated independently of the first heating
circuit. A low loss header can be used for this hydraulic decoupling
between the boiler and heating circuit. This is controlled by the
function module WM10. The WM10 can also be used for DHW
heating via a cylinder loading pump.

Tips on economical heating
Here are a few tips on how to heat economically, without sacrificing
comfort, using your RC30:
z Only heat if you need warmth. Use the heating programs preset
in the RC30 or those which you have tailored to your personal
needs.
z Ventilate correctly during the cold season: Open the windows
wide three to four times per day for approx. five minutes.
Having the window slightly open all the time does not provide
fresh air changes and wastes valuable energy.
z Close the thermostatic radiator valves when the room is being
ventilated.
z Windows and doors are places where a lot of heat is lost. So
check that the doors and windows are correctly sealed. At
night, close your shutters and blinds (if installed).
z Heat in an energy-conscious manner during in spring and
autumn, and make use of the summer/winter changeover
function (see Chapter 9.10 "Setting summer/winter
changeover", page 72). In summer mode the heating is
switched off and only DHW is heated. In winter mode the
heating and DHW are activated.
z Never position large objects such as a sofa or a desk
immediately in front of the radiators (maintain a clearance of at
least 50 cm). Otherwise the heated air cannot circulate and
heat the room adequately.
z In those rooms which you occupy during the day, you can set
a room temperature of 21 °C, for example, whilst 17 °C may be
sufficient at night. You can do this using day and night modes
(see Chapter 7 "Basic functions", page 20).
z Never overheat rooms. Overheated rooms are unhealthy and
cost energy and money. If you reduce the daytime room
temperature, from 21 °C to 20 °C, for example, you will save
around six percent on your heating bill.
We reserve the right to make any changes due to technical modifications.

Tips on economical heating
z A comfortable room climate depends not only on the room
temperature but also on the relative humidity. The drier a room,
the cooler it feels. You can improve the relative humidity with
houseplants.
z You can also save energy when heating DHW by running the
circulation pump in intermittent mode only. Research has
shown that it is generally sufficient to run the DHW circulation
pump for three minutes in every 30.
z Arrange with your installer to service your heating system
annually.

Basic functions
Basic functions
This chapter describes how to change room and DHW
temperatures, the advantages of automatic mode, how to make
effective use of manual mode, etc.
The basic functions are controlled by pressing and holding a button
on the right-hand side of the RC30 and turning the dial.
7.1
Changing the room temperature directly
If it is too cold in the house in general, increase the room
temperature on the RC30 and leave the thermostatic radiator
valves unaltered.
Set the required room temperature by turning the dial. (Note: To do
this the RC30 flap must be closed.)
USER NOTE
If your heating system has several heating circuits, you must
select the correct heating circuit first (see Chapter 8.6 "Selecting
a heating circuit", page 35). Only then can you set the room
temperature.
7.2
Selecting the operating mode
You can operate the RC30 in two ways:
–
in automatic mode
–
in manual mode
We reserve the right to make any changes due to technical modifications.

7.2.1
Selecting automatic mode
Generally, buildings are heated less at night than during the day.
In automatic mode the RC30 changes over automatically between
day mode (standard heating mode) and night mode (reduced
heating mode). This means that you do not have to adjust the
thermostatic radiator valves every morning and evening.
The times at which the heating system changes from day to night
mode – and vice versa – are factory-set via the heating program.
However, you or your installer can modify this setting (see Chapter
8.9 "Selecting a preset heating program", page 40).
The heating program raises or lowers the room temperature at
fixed times. The time at which the system changes from night to
day mode (and vice versa) is known as the "switching point".

heating only) because of the outside temperature. In such a case
choose manual mode to run the heating. The heating is then
permanently on and must be turned off by pushing the
"AUT" button.
You can also change the setting for automatic summer/winter
changeover (see Chapter 9.10 "Setting summer/winter

Selecting and modifying a heating program
What is a heating program?
A heating program provides the automatic changeover of
operating mode (day and night mode) at fixed times. In the factory
setting the heating program also sets the times for DHW heating
and operation of the circulation pump. You can also set up a
separate DHW or circulation program.
Before you select a heating program, consider the following:
–
At what time in the morning do you want your home to be
warm? Does this time also depend on the day of the week?
–
Are there days when you don't want to heat during the day?
–
From what time in the evenings do you no longer need
heating? This too may depend on the day of the week.
With the RC30, Buderus offers eight different, pre-programmed
heating programs for direct selection.
USER NOTE
Check after commissioning, whether the selected heating
program suits your lifestyle. If this is not the case, several options
are available for matching the heating program to your individual
requirements so as to optimise heating comfort and energy
consumption.
Time taken to heat up the home
The time taken for your heating system to heat up individual rooms
may vary. This will be subject to the outside temperature, the
building insulation and the drop in room temperature.
The "Optimisation " function of the RC30 calculates the various
heat-up times. Ask your installer whether he has activated this
function. If he has, all you need to do is enter the times at which
your home should be warm.

9.10 Setting summer/winter changeover
If your heating system is in automatic mode (LED next to the "AUT"
button illuminated), the RC30 performs the summer/winter
changeover automatically. In summer mode the heating is
switched off and only DHW is heated. In winter mode the heating
and DHW are activitated.
Automatic summer/winter changeover depends on the following
factors:
–
Outside temperature
–
Type of construction/thermal insulation
Outside temperature in °C
The "adjusted" outside temperature is calculated from the outside
temperature and the thermal insulation of your home (Fig. 14).

Current and adjusted outside temperature in comparison
Item 1:
Current outside temperature
Item 2:
Adjusted outside temperature
The adjusted outside temperature is a theoretical variable
calculated by the RC30, which takes into account the heat storage
capacity of the walls. For example, with an outside temperature of
10 °C and the heating switched off, the temperature inside the
home can still be 16 °C. The inside temperature falls slowly.

USER NOTE
For summer/winter changeover, your installer must have set up
outside temperature dependent control (see "Outside
temperature dependent control", page 6).
Summer/winter changeover does not apply to room temperature
control.
Summer mode
A changeover threshold for summer/winter changeover is entered
in the RC30 (factory setting 17 °C). When the adjusted outside
temperature exceeds the changeover threshold, the heating
system switches to summer mode (DHW heating only).
If you require heating for a short period in summer mode:
Press the "Day mode" button to switch to normal heating mode for
a short time (see Chapter 7.2.2 "Selecting manual mode",
page 23).
Press "AUT" to return to automatic summer mode.
Winter mode
When the adjusted outside temperature falls below the
changeover threshold, the heating system switches to winter mode
(heating and DHW heating).

9.12 Setting the preheat phase for a gas-operated heat pump
(not in the UK)
If a gas-operated heat pump (Loganova GWP) is installed in your
heating system, we recommend that you set a preheat phase. This
setting has no effect on other devices.
During the preheat phase the heat pump unit preheats the heating
system without the peak load boiler. The continuous running of the
heat pump generally increases the overall efficiency and saves
more energy than a reduction in the room temperature.
The preheat phase starts at the preset time before the day mode
of the first heating circuit.
z Open the additional menu (see Chapter 9.1 "Opening and
using the additional menu", page 57).
Using the dial select "ADD MENU HP PREHEAT".

Troubleshooting
This chapter details frequently asked questions about your heating
system and their respective answers. This will, in many cases,
enable you to troubleshoot perceived faults. At the end of the
chapter, faults and their remedies are listed in a table.
10.1 Frequently asked questions
Why do I set a room
temperature, even
though it is not
measured?
When you set the room temperature, even though the room
temperature is not measured, you change the heating curve. This
also changes the room temperature. When you set the room
temperature, the temperature of the water in the boiler changes
and hence the temperature of the radiators (see "How does the
RC30 work?", page 5).
Why does the room
temperature measured
with a separate
thermometer not
correlate with the set
room temperature?
Different values influence the room temperature. If the RC30 is
mounted against a cold wall, it will be influenced by the cold
temperature of the wall. If it is installed in a warm part of the room,
e.g. close to a radiator, it will be influenced by the heat from that.
This is why a separate thermometer can display a different room
temperature from that set on the RC30.
To compare the actual room temperature with the values
measured by another thermometer, the following are important:
–
The separate thermometer and the RC30 must be located
close together.
–
The separate thermometer must be accurate.
–
Do not compare the room temperatures when the heating
system is in the process of heating up as the RC30 and the
separate thermometer may respond to the increasing room
temperature at different speeds.
If you have checked these points and there is still a discrepancy,
you can use the "Calibrating the room temperature" function (see
Chapter 9.4 "Calibrating the room temperature", page 64).
We reserve the right to make any changes due to technical modifications.
78
Operating instructions RC30 programmable room thermostat • Issue 02/2006
Troubleshooting
Why do the radiators
get (too) hot when the
outside temperature is
relatively high?
10
If you have a heating system with a heating circuit and no mixer
valve, this is normal (see "What are heating circuits?", page 9).
The circulation pump only starts up when the boiler reaches a
predefined flow temperature. If the flow temperature is higher than
the temperature required on the basis of the outside temperature,
the radiators may get hotter for a short time. The heating control
unit detects this and quickly responds accordingly. Do not adjust
the thermostatic valves on the radiators and wait until the set room
temperature is reached.
In summer mode, radiators can heat up in certain circumstances
for a short time: The circulation pump is started up automatically at
a predefined interval to prevent it from blocking. If the pump
happens to be started up immediately after DHW heating, the
unusable residual heat is dissipated via the heating circuit and the
radiators.
Why does the heating
system pump run
during the night, even
though there is little or
no heating on?
This depends on the setting chosen for night setback by your
installer (see "Why do I need a heating program?", page 8). Please
ask your installer about the setback mode setting.
–
Total shutdown: The heating system (and therefore also the
pump) is automatically switched off in night mode. If the
outside temperature drops below the frost protection
temperature, the pump is automatically switched on by the
"Frost protection" function.
–
Reduced room temperature: The pump continues to run
even if the heating is reduced, in order to maintain the lower
room temperature.
–
Change between total shutdown and reduced heating
subject to room temperature or outside temperature: The
heating system is switched on automatically if the actual
temperature falls below the set value. The pump then starts up
too.
We reserve the right to make any changes due to technical modifications.

Troubleshooting
The actual room
temperature is higher
than the set room
temperature. Why is
the boiler still running?
The boiler may heat up in order to heat DHW.
Your heating system can be set to three possible control modes
(see "How does the RC30 work?", page 5):
–
Room temperature control: The boiler switches off when the
set room temperature is reached.
–
Outside temperature dependent control: The heating
system runs according to the outside temperature.
–
Outside temperature dependent control with room
temperature hook-up: The heating system uses the
advantages of both of the above control modes.
In the last two cases, the boiler may run even if the actual room
temperature is higher than the set room temperature.
We reserve the right to make any changes due to technical modifications.
