2.5 Validity of these instructions for function modules (accessories)
These instructions also apply to the programming unit when used in conjunction with the MM10
mixer module and the WM10 low loss header module.
Additional setting options may be found in some menus, if your heating system is equipped with
alternative function modules (e.g. solar module SM10). These setting options are explained in a
separate manual.
2.6 Accessories
For detailed information regarding suitable accessories, see the catalogue.
• Mixer module MM101) for control of a 3-way valve. A description of the MM10 is included in the
RC35 instructions.
• Low loss header module WM101) for operating a low loss header
• Solar module and additional EMS modules (e.g. connection module ASM10)1)
• Remote control1) (e.g. RC2x, RC20/RF) respectively for controlling one heating circuit
• Outside temperature sensor, external room temperature sensor
1) The use of modules is not possible for boilers with UBA1.x or DBA.

Installation
Installation
3.1 Choosing the right installation position
3.1.1 Installation in reference room
If the system is room-temperature controlled, the following requirements must be observed:
• Installation position on an internal wall (Æ Fig. 1)
• Maintain the specified distance from the door (to avoid draughts).
• Allow clearance below the programming unit (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. External heat sources in the reference room (e.g. sunlight or other heat sources such as
an open fire) affect the control functions. This means it may be too cold in rooms without external
heat sources.
• Always open the thermostatic radiator valves fully in the reference room to prevent the two
temperature controllers influencing each other.
If there is no suitable reference room, we recommend setting the system to weathercompensated control instead (this requires an outside temperature 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
Installation directly on the boiler is possible where the boiler is equipped with the Energy
Management System (EMS).
The outside temperature sensor for weather-compensated control is not delivered as standard, but
can be ordered as an accessory.
3.2 Types of installation
The programming unit can be installed in three different ways:
• As only programming unit in the system (factory setting): the programming unit is installed in the
living space (reference room) or on the boiler.
Example: detached house with one heating circuit.
• As the only programming unit in a heating system with two or more heating circuits1) (Æ Fig. 2
[1]).
Examples: underfloor heating on one floor, radiators on the others; or a main flat together with a
separate granny flat or doctor's surgery.
• In conjunction with a remote control (e.g. RC2x, RC20/RF, Fig. 2, [2]). In this case there are
always two separate heating circuits. Remote control units cannot be used for boilers with
UBA1.x.
Examples: underfloor heating on one floor, radiators on the others; or a main flat together with a
separate granny flat or doctor's surgery.

3.3 Installation and connections
Only use the wall mounting base with screw terminals.
B Replace wall mounting bases without screw terminals that may already be installed.
The wall mounting base can be attached directly to the wall or on a flush box.
When mounting on a flush box, note the following:
B Draught from within the flush box must not be able to falsify the capture of the room temperature
by the programming unit.
If required, stuff the flush box with insulation material.
B Use horizontal or vertical fixing holes [4].
B Fit the wall mounting base (Æ Fig. 3, left).
B Connect the two-core BUS cable from the Energy Management System (EMS) at terminals “RC”
[5].
– Cable type: 2 x 0.75 mm2 (0.5 – 1.5 mm2), max. length 100 m
– Polarity is irrelevant for the two wires.
B Do not lay the cables parallel to power cables.

5.6 Shutting down/switching off
The RC35 programming unit is powered via the heating system and remains permanently ON.
The heating system is only switched off, for example, for maintenance work.
B To start up and shut down the heating system: set the ON/OFF switch on the boiler programming
unit to 1 (ON) or 0 (OFF).
After shutting down or in the event of a power failure, the date and time are retained for
up to 8 hours. All other settings are retained permanently.
5.7 Operating information
EMS BUS subscribers
In a BUS system, only one subscriber can carry out the calculations for a heating circuit.
Consequently, only one RC35 programming unit may be installed in each heating system. If
additional room controllers (e.g. RC2x) are required, these must be installed as remote control
units1) with a set heating circuit address (Æ page 27).
Disable this on boilers with integral weather-compensated control.
Thermostatic radiator valves in the reference room
Radiators in the reference room do not require thermostatic valves2) for room temperaturedependent control. Fully open any thermostatic radiator valves in the reference room.
Pump kick1)
In all operating modes, all the heating circuit pumps are switched on and then off again for
10 seconds every Wednesday at 12 noon to prevent pump damage. The mixers are then set to
“OPEN” for 10 seconds and then “CLOSED”. All pumps and mixers then return to their normal,
regulated operation.

6.1.1 Building type (adjusting the outside temperature)
A building's heat storage capacity and its characteristic resistance to heat transfer will delay the
effect of outside temperature fluctuations on the rooms inside. Consequently, it is not the current
outside temperature that is crucial but the so-called adjusted outside temperature.
Parameter building type enables the adjustment to be applied that takes account of the fluctuating
outside temperatures. This enables the control to be matched to the characteristics of the building.
The control unit calculates the time constant for adjusting the outside temperature, using the factor
given in Tab. 10 for the stated building type and an internal multiplier, the “runtime” (= 6 minutes).
The time constant is the product of: factor x runtime = adjustment time constant in hours.

B To monitor the calculated, adjusted outside temperature and the currently captured
outside temperature: open the menu diagnosis\monitor valueboiler / burner.
6.1.2 Minimum outside temperature
The minimum outside temperature is the mean of all the coldest outside temperatures of recent
years, and helps to determine the heating curve. The value can be taken from the heat requirement
calculation which should be done for every building, or from the climatic zone chart for your region.

6.3.2 Control mode (outside temp. contr./room influence)
The temperature of the heating water in the boiler is defined by the heating curve in the Logamatic
control unit. You can select whether this heating curve will be influenced solely by the outside
temperature, or by a mixture of outside temperature and room temperature.
• outside temp. contr.: If this setting is entered, the boiler temperature calculated in the control
unit will be regulated by variation in the adjusted outside temperature in combination with
selected settings for set room temperature, offset, design temperature and minimum outside
temperature. This temperature is then delivered to the radiators or underfloor heating system by
means of permanent operation of the heating circuit pump.
The only circumstances in which this setting can result in the heating circuit pump being
switched off are summer mode, night setback (subject to the selected setback mode) or DHW
mode (only with DHW priority).
• outside temp. contr. with room temperature hook-up (factory setting): this form of control
functions like a pure weather-compensated control with the difference that parameter maximum
room influence enables the determination whether and to what extent the room temperature
can influence the heating curve.
The programming unit/remote control must be installed in a reference room to ensure that a
representative room temperature is captured.
The higher the parameter is set, the higher the proportion of the room temperature effect on the
heating curve (factory setting 0 Kelvin). This applies when the room temperature exceeds or falls
below the set room temperature. If the maximum room influence parameter is set to 0, the
heating characteristics will be controlled solely by outside temperature.

6.3.3 Heating curve
Parameters: design temperature, maximum and minimum flow temperature and room temperature
offset (parallel offset)
The heating curve is the basis for economical and comfortable operation of the heating system with
weather-compensated control. To calculate this curve, the Logamatic control system requires you
to enter a number of parameters for the heating system, from which it automatically calculates the
optimum heating curve by means of a mathematical formula, taking the adjusted outside temperature
and room control temperature into account.
The room control temperature is an internal operand which is a combination of the required room
temperature (set room temperature) and room influence.
This can be used by the user to influence the heating curve directly by varying the set room
temperature.
The heating curve (Æ Fig. 7, page 33) is generally determined by its base and end points. The base
point is located at 20 °C flow temperature at a room temperature of 20 °C with an adjusted outside
temperature of 20 °C. The end point of the heating curve must be set in accordance with the design
temperature of the heating system.
The two parameters minimum outside temperature (the lowest outside temperature to be
expected in a region, page 25) and std. temp. (the flow temperature that should be reached at
minimum outside temperature) are crucial for the heating curve (level/slope) (Æ Fig. 7, left).
The X-axis of the heating curve graph refers to the range from +20 °C to – 20 °C.
For parameter std. temp. the minimum outside temperature set under system data is
shown by a circle. However, if a minimum outside temperature below – 20 °C is
entered, then the depiction is no longer accurate (the circle then lies away from the
heating curve).
The minimum flow temperature parameter can be used to define a minimum set value (Æ Fig. 7,
[4], page 33). The burner starts again if the set value is no longer achieved.
The heating curve is offset in parallel either up or down by adjusting parameter rm. tmp. offset and/
or the set room temperature (Æ Fig. 7, right, page 33). Setting the offset may be advisable should
the room temperature measured by a thermometer deviate from the selected set value.

6.3.4 Setback modes (night setback)
There are a number of different setback modes available, which allow night setback to be adjusted
to suit the differing needs of the user:
• reduced operation: the rooms are maintained at a reasonable temperature at night by constant
heating operation (pump runs constantly). A set room temperature for nighttime can be set. It is
at least 1 K lower than the set day temperature. The heating curve is calculated in accordance
with these details.
We recommend these settings for an underfloor heating system.
• shut-down mode: boiler and heating circuit pump are off, frost protection is active. The pump
only starts in frost protection mode.
This setting is not recommended if there is a risk that the building would cool down too severely.

6
System settings (Service menu – Settings)
• Room setback mode: The heating system operates as if in setback mode (as described under
“reduced operation”), if the room temperature falls below the selected night temperature (set
value). Boiler and heating circuit pump stop (as described under setback mode “shut-down
mode”) if the room temperature exceeds the set night temperature by more than 1 K.
This setback mode is only possible if a programming unit/remote control is installed in a
representative room (reference room) or if the room temperature is captured by an external room
temperature sensor.
• Outdoor setback mode: The heating system operates as in reduced heating mode (as
described under setback mode “reduced operation”) if the adjusted outside temperature does
not reach the value of an adjustable outside temperature threshold. The heating system remains
off above this threshold (as described under setback mode “shut-down mode”). This setback
mode is suitable for heating circuits which do not have their own programming unit / remote
control unit. The operating mode protects the rooms from cooling down too much once a certain
outside temperature is reached.
6.3.5 Frost protection
The frost protection function offers the following options:
• no frost protection (frost protection is switched off).
• outside temp. (outside temperature sensor required) The heating circuit pump starts
automatically if the outside temperature falls below the adjustable frost protection temperature
threshold.
• room temperature (room temperature sensor of the RC35 or RC2x) The heating circuit pump
starts automatically if the room temperature falls below the permanently set value of 5 °C. The
heating circuit pump stops automatically if the room temperature rises above 7 °C.
CAUTION: System damage due to frost!
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 outside temp. setting.
The setting room temperature offers no absolute frost protection, as lines routed
through external walls may freeze up, for example, although the temperature in the
reference room may be significantly above 5 °C.
At what outside temp. should reduction be interrupted?
EN 12831 requires that, for the maintenance of a level of comfortable heat, heating areas and heat
sources be designed to deliver a specific output if the heating system cools down to a specific value
through night setback.

Calibrating the displayed room temperature (calibration)
If there is a separate thermometer near the programming unit, it may show a different room
temperature to that shown on the programming unit. You can use this function to adjust (“calibrate”)
the programming unit to match the thermometer.
Before calibrating the room temperature, consider the following:
• Is the thermometer more accurate than the programming unit?
• Is the thermometer located close to programming unit so that they are both subject to the same
heat influences (e.g. sunlight, fireplace)?
A thermometer may indicate temperature fluctuations more slowly or rapidly than the
programming unit.
B Therefore, never calibrate the programming unit during phases when your heating
system is cooling down or heating up.
Example: if the thermometer is showing a temperature 0.5 °C higher than the programming unit,
enter +0.5 K as the calibration value.

Faults are categorised as follows:
• current errors are all unresolved faults currently present in the system. These can be one of the
following types: locking, blocking or plant error.
• locking fault1): Manually reset the heating system after the fault has been removed. For this,
press RESET on the boiler.
• blocking fault1): With blocking faults, the heating system continues to operate automatically,
as soon as the fault has been removed.
• plant errors relating to the heating system are logged in the RC35. Exceptions are boiler or
burner faults that are either “locking” or “blocking” faults. The heating system keeps operating as
much as possible during the fault; a reset is not required.
For a list of the locking and blocking faults, which vary depending on the boiler, see the
installation and maintenance instructions for the boiler.
