2 Product description

2.1 Correct use

The RC35 control unit is intended for the operation and control of Buderus heating systems in single
and multi-family houses.

The boiler must be equipped with EMS (energy management system).

The user interface must not be used in conjunction with Logamatic 2000/4000 control units.
We recommend that the heating system is always operated with a user interface (only emergency
operation is possible without a user interface).

These instructions describe all the possible functions of the RC35. Some of these functions may
not be available, depending on which boiler (burner control unit) is used. For more information, refer
to the relevant chapter.

For information on the burner control units used, refer to the DIAGNOSIS\VERSIONS menu
(Æ page 45).

Installation

3.1 Choosing the right installation location

3.1.1 Installation in reference room

If the system is room-temperature controlled, the following requirements must be met:

• Installation on an internal wall (Æ Fig. 1).

• Maintain the specified distance from door(s) (to avoid drafts).

• Allow clearance below the user interface (Æ Fig. 1, shaded area) (to ensure correct temperature
measurement).

• The reference room (= installation room) must be as representative as possible of the entire home
(or zone) if possible. External heat sources in the reference room (like sunlight or an open
fireplace) affect the control's function. This means it may be too cold in rooms without those
external heat sources.

• The thermostatic valves on the radiators (if installed) in the reference room must always stay fully
open so that the two temperature controls do not affect one another.

If there is no suitable reference room, we recommend setting the system to outdoor
temperature control instead (this requires an outdoor sensor). Alternatively, you could
install an external room temperature sensor in the room with the greatest heating
requirements (e.g. living room).

3.1.2 Installation on boiler

The unit can be installed directly on boilers equipped with EMS.

3.2 Types of installation

The user interface can be installed in three different ways:

• As the only user interface in the system (factory setting): the RC35 user interface is mounted in

a room in the home (the reference room) or on the boiler.
Example: single-family house with one heating zone.

• As the only user interface in a heating system with two or more heating zones (Æ Fig. 2).

Examples: radiant floor heating on one story, radiators in the other.

terminals (Æ Fig. 3, [4]) (the jumper is factory-installed).

B If the RC35 is operated with an external room temperature sensor (optional), the factory-installed

jumper on “EXT” must be removed and the external room temperature sensor must be connected
there instead.

5.7 Operating tips

Devices on the EMS bus

In a bus system, only one device can carry out the calculations for a heating zone. Therefore only
one RC35 can be installed in a heating system. If additional room controllers are needed, they are
installed as remote control units with a designated heating zone (Æ page 28).

Thermostatic radiator valves in the reference room

With room temperature control, thermostat valves do not need to be installed on the radiators in the

1)

reference room

. If there are thermostatic radiator valves in the reference room, they must be fully

open at all times.

Pump anti-seize Feature

In all operating modes, all heating zone pumps are switched on for 10 seconds every Wednesday
at 12 noon to prevent pump damage. The mixing valves are then set to “OPEN” for 10 seconds and
then to “CLOSE”. After 10 seconds, all pumps and mixing valves then return to their normal,
regulated operation.

6.1.1 Type of building (“damping” of outdoor temperature)

A building's heat storage capacity and its characteristic resistance to heat transfer will delay the
effect of outdoor temperature variation on the rooms inside. As a consequence, it is not the current
outdoor temperature that is crucial to the heat demand of rooms, but the so-called “adjusted outdoor
temperature”.

The building type parameter can be used to set the level of delay with which variations in outdoor
temperature are registered. This allows the heating system control adapt to the characteristic
behavior of the building.

The controlls calculates the time constant for the delay in response to the outdoor temperature

Parameter:
building type Type of construction

light Buildings with small heat storage capacity and low to medium levels of

insulation, e.g. 2x4 wood frame or prefabricated construction with typical
insulation.

medium Buildings with medium heat storage capacity and high levels of insulation,

e.g. 2x6 wood frame or cinder block construction with above average insulation
(factory default).

heavy Massive buildings with high heat storage capacity and high levels of insulation,

e.g. poured concrete, heavy brick or heavy cinder block construction with
excellent insulation.

Fig. 5 This greatly simplified example shows how the delayed response to outdoor temperature

follows the outdoor temperature, but does not reach its extreme values.

1 Current outdoor temperature
2 Adjusted outdoor temperature

With the factory setting, changes in the outdoor temperature will affect the calculations
for outdoor-temperature-based control after a delay of no more than three hours
(30 x 6 minutes = 180 minutes).

B To monitor the calculated, delayed response to outdoor temperature and the

currently recorded outdoor temperature:
open the menu Diagnosis\Monitor\boiler/burner.

6.1.2 Minimum outdoor temperature

The “minimum outdoor temperature” is the mean of all the coldest outdoor temperatures of recent
years, and helps to determine the heating characteristics. The value can be taken from the heat
requirement calculation that should be done for every building, or from the climatic zone chart of your
region.

6.3.2 Control mode (outdoor temperature controlled/room influence)

The temperature of the heating water in the boiler is defined by the heating characteristics
determined in the Logamatic controls. A selection can be made whether these heating
characteristics will be influenced solely by the outdoor temperature, or by a combination of outdoor
temperature and room temperature.

• Outdoor temperature controlled: The boiler temperature calculated in the controls will be
controlled by variation in the “delayed” response to outdoor temperature in combination with
selected settings for target room temperature, offset, standard temperature and minimum
outdoor temperature. This temperature is then delivered to the radiators or radiant floor heating
by means of permanent operation of the heating zone pump. The only situations in which this
setting could result in shut-down of the heating zone pump are summer operation, night setback
(depending on the reduction mode selected) or DHW mode (only with domestic hot water
priority).

• Outdoor temperature controlled, influenced by room temperature (factory default):
this form of control works in exactly the same way as pure outdoor temperature control, except
that you can use the maximum room influence parameter to determine whether and to what
extent the room temperature should influence the heating characteristics.
The remote control unit must be installed in a reference room, so that a representative room
temperature is recorded.
The greater the parameter set, the greater the influence of the room temperature on the heating
characteristics (factory setting: 0 °F (0 °C)). This applies when the room temperature exceeds or
falls below the target room temperature. If the maximum room influence parameter is set to 0,
the heating characteristics will be controlled solely by outdoor temperature.

6.3.3 Characteristic heating curve

Parameters: Standard temperature, maximum and minimum supply temperature and room
temperature offset (parallel shifting of characteristic heating curve)

The characteristic heating curve forms the basis for economical and easy operation of the heating
system with outdoor reset. To calculate the characteristic heating curve, the Logamatic control uses
a number of parameters.

This calculation takes into account the “delayed” response to outdoor temperature changes and the
room temperature. The room temperature is internally calculated, based on target room temperature
and the room influence factor.

This allows the user to influence the heating characteristics directly by modifying the target room
temperature.

The heating characteristic curve (Æ Fig. 6, page 34) is determined by the base point and end point.
The base point is located at 14 °F (–10 °C) supply temperature at a room temperature of 68 °F
(20 °C). The end point of the heating characteristic curve must be set in accordance with the design
temperature of the heating system.

The gradient of the heating characteristic curve (the shape of the curve) is determined by the param­eters minimum outdoor temperature (the lowest outdoor temperature expected in a particular
region, Æ page 26) and the standard temperature (the supply temperature which should be
reached when the outdoor temperature is at minimum) (Æ Fig. 6, left).

The x-axis of the heating characteristic curve shown on the display covers the range
from +68 °F to –4 °F (+20 °C to –20 °C). With the parameter std. tmp., the minimum
outdoor temperature is represented by a circle. However, the diagram will not be quite
correct if a minimum outdoor temperature below –4 °F (–20 °C) is entered (the circle
will no longer be on the heating characteristic curve).

The minimum supply temperature parameter can be used to define a minimum target value
(Æ Fig. 6, [4]). If the temperature falls below this value, the burner is fired.

The characteristic heating curve can be shifted, up or down, in parallel to the original curve, by
adjusting the room temperature offset parameter and/or the set room temperature
(Æ Fig. 6, right). This feature should be used if, for example, the room temperature measured with
a thermometer differs from the set target value.

6.3.4 Reduction modes (night setback)

There are a number of different reduction modes available, which allow night setback to be adjusted
to suit the differing needs of the user:

• setback mode: The rooms are maintained at a reasonable temperature by constant heating
operation (the heating zone pump runs constantly). A target room temperature for nighttime can
be set. This must be at least 2 °F (1 °C) lower than the daytime target room temperature. The
heating characteristics will be calculated in accordance with this setting.This setting is
recommended for radiant floor heating.

Logamatic EMS RC35 user interface - Subject to technical modifications.34

Entering system settings (Service menu – Settings)

6

• shut-down mode: The boiler and the heating zone pump are switched off, and frost protection

is activated. The heating zone pump runs only for purposes of frost protection. Not recommended
if there is a risk that the building could cool down too much.

• Room setback mode: If the room temperature falls below the set night temperature (the target

value), the heating system will operate in the same way as for reduced heating operation (as
described under reduction mode “setback mode”). If the room temperature exceeds the target
night temperature by more than 2 °F (1 °C), the boiler and the heating zone pump are switched
off (as described under reduction mode “shut-down mode”). This reduction mode is only possible
if a remote control unit has been installed in a representative room (the reference room) or if the
room temperature is recorded using an external room sensor.

• Outdoor setback mode: If the “delayed” response to outdoor temperature falls below a user-

defined threshold, the heating system will operate in the same way as for reduced heating
operation (as described under “setback mode”). Above this threshold, the heating system will be
switched off (as described under reduction mode “shut-down mode”). This reduction mode is
suitable for heating zones that do not have their own remote control unit, and protects the rooms
from cooling down too much once a certain outdoor temperature is reached.

6.3.5 Frost protection

The frost protection function comprises the following options:

• no frost protection (frost protection is switched off)

• outdoor temperature (outdoor temperature sensor required) If the outdoor temperature falls

below the adjustable frost protection temperature threshold, the heating zone pump is switched
on automatically.

• room temperature (room temperature sensor in the RC35 or RC20) If the room temperature

falls below the fixed value of 41 °F (5 °C), the heating zone pump is switched on automatically. If
the room temperature rises above 44 °F (7 °C), the heating zone pump is switched off
automatically.

CAUTION: Risk of system damage due to freezing. The settings no frost protection
and room temperature provide either no frost protection or inadequate frost
protection. When these settings are selected, the display shows a message indicating
the risk of freezing.

B For reliable frost protection, use the outdoor temperature setting.

The room temperature setting does not provide absolute frost protection because
pipes laid in external walls (for example) could freeze even though the temperature in
the reference room might be clearly above 41 °F (5 °C) due to external heat sources
(fireplace etc.).

At what outdoor temperature should setback be cancelled?

In the parameter At what outdoor temp. should the setback be canceled?, you can set an
outdoor temperature threshold (this threshold applies to the “delayed” response to outdoor
temperature; Æ page 25).

Fig. 7 shows how the frost protection function works, without this parameter activated and with it
activated. Settings selected: frost protection by outdoor temperature; frost protection
temperature 41 °F (5 °C).

Calibration of the displayed room temperature

If there is a separate thermometer near the controls, it may show a different room temperature to that
shown on the RC35. This function can be used to adjust the RC35 to match the thermometer
(i.e. “calibrate”).

Before calibrating the room temperature, consider the following:

• Is the thermometer more accurate than the RC35?

• Is the thermometer located close to the unit so that they are both subject to the same heat
influences (e.g. sunlight, fireplace)?

Other thermometers may show temperature changes more slowly or more quickly than
the RC35.

B Never calibrate the controls when your heating system is in the process of cooling

down or heating up, but only in steady state conditions.

Example: if the thermometer is showing a temperature 2 °F (1 °C) higher than the controls, enter
“+2 °F (+1 °C)” as the calibration value.

The most recent fault from the fault memory can be displayed using the error message
(e.g. to investigate a fault).

The faults are divided into the following categories:

• Current faults are all unresolved faults currently present in the system. These can be one of the
following types: locking, blocking or system error.

• Locking faults: When the fault is remedied, the heating system needs to be unlocked manually.
To do so, press the Reset button on the boiler.

• Blocking type faults: With blocking faults, the heating system resumes operation automatically as
soon as the fault has been rectified.

• System faults in the heating system are logged in the RC35, with the exception of faults in the
boiler or the burner, which are either “locking” faults or “blocking” faults errors. The heating
system continues to run – where possible – during the fault state; no reset is necessary.

For a list of the locking and blocking faults, which vary depending on the boiler, see the
installation and maintenance instructions of the boiler.
