2 Information about the product
2.1 Correct use
The RC35 programming unit must only be used to operate and control Buderus heating
systems in residential buildings.
The boiler must be equipped with EMS (energy management system) or UBA1.x (univer-
sal burner control).
The programming unit must not be used in conjunction with Logamatic 2000/4000 con-
trol panels.
We recommend that the heating system is always operated with a programming unit (only
emergency operation is possible without a programming unit).
If RC20 remote control units manufactured before 2006 are being used, only two remote
control units can be connected. If you have any questions about this, please contact your
local Buderus office.

2.5 Validity of these instructions for function modules (accesso-
ries)
These instructions also apply to the programming unit when used in conjunction with the
MM10 mixer module and the WM10 low loss header module.
If the heating system is equipped with other function modules (e.g. SM10 solar module),
you will find additional setting options in some menus. These are described in separate
instructions.
2.6 Accessories
For precise information regarding suitable accessories, refer to the catalogue.
– MM10 mixer module1for controlling a three-way mixing valve. The instructions for the
MM10 form part of the RC35 instructions.
– WM10 low loss header module1for operating a hydraulic separator
– Solar module and other EMS modules (e.g. ASM10 connection module)1
– Remote control unit1(e.g. RC20/RC20RF) for controlling a particular heating circuit
– Outside temperature sensor, external room temperature sensor
1) The use of modules is not possible with boilers with UBA1.x and DBA.

Installation 3
RC35 programming unit - Technical specifications are subject to change without prior notice. 9
3 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 (Fig. 1)
– Maintain the specified distance from the door(s) (to avoid draughts).
– Allow clearance below the programming unit (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 (like sunlight or other heat
sources such as an open fire) affect the control's function. This means it may be too
cold in rooms without external heat sources.
– The thermostatic valves on the radiators in the reference room must always stay fully
open so that the two temperature controls do not affect one another.
Fig. 1 Minimum clearances for installation in a reference room
If there is no suitable reference room, we recommend setting the system to out-
side temperature control instead (this requires an outside sensor). Alternatively
you could install an external room sensor in the room with the greatest heating
requirements (e.g. living room).

Installation

3.1.2 Installation on boiler
The unit can be installed directly on boilers equipped with EMS (Energy Management Sys-
tem).
The outside temperature sensor for outside temperature control is not delivered as stand-
ard, but can be ordered as an accessory.
3.2 Types of installation
The programming unit can be installed in three different ways:
– As the only programming unit in the system (factory setting): the programming unit is
mounted in a room in the home (the 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
(Fig. 2, 1).
Examples: underfloor heating on one floor, radiators on the others; or a main flat
together with a separate annex.
– In conjunction with a remote control unit (e.g. RC20/RC20RF, Fig. 2, 2). In this case
there are always two separate heating circuits. Remote control units cannot be used
with boilers with UBA1.x.
Examples: underfloor heating on one floor, radiators on the others; or a main flat
together with a separate annex.
Fig. 2 Options for a heating system with two heating circuits
1 Both heating circuits are controlled by one programming unit.
2 Each heating circuit has its own programming unit / remote control unit.
1) Not possible with boilers with UBA1.x and DBA.

Installation 3

3.3 Installation and connection
The wall bracket can be attached directly to the wall or on a flush-mounting box.
When mounting on a flush-mounting box, note the following:
– Draughts from the flush-mounting box must not distort room temperature recording in
the programming unit (you may need to pack the flush-mounting box with insulation
material).
– Use the horizontal or vertical mounting holes (Fig. 3, 4).
zMount the wall bracket (Fig. 3, left).
zConnect the two-wire bus cable from the Energy Management System (EMS) to the
“RC” cable terminals (Fig. 3, 5).
– Cable type: 2 x 0.75 mm2(0.5 – 1.5 mm2), length max. 100 m
– The two wires are not polarity sensitive.
– Do not lay the cables next to power cables.

2 Screws (included with the unit) for surface-mounting on the wall
3 Vertical mounting holes for mounting on a flush-mounting box

Please use only the wall bracket with screw-type terminals.
zI
f there is a wall bracket without screw-type terminals already fitted, replace it.

zIf the RC35 is operated without an external room sensor, a jumper is required on the
“EXT”terminals (Fig. 3, 6) (the jumper is factory fitted).
zIf the RC35 is operated with an external room sensor, the factory-fitted jumper on “EXT”
must be removed and the external room sensor must be connected there instead.
3.4 Attaching or removing the programming unit
Attaching the programming unit
zHook the top of the programming unit onto the mounting plate in the direction shown
by the arrows (Fig. 4, A1).
zPush the bottom of the programming unit against the mounting plate in the direction
shown by the arrow until it clicks into place (Fig. 4, A2).
Removing the programming unit
zPress the button on the underside of the mounting plate in the direction shown by the
arrow (Fig. 4, B1) and pull the programming unit forward at the same time (Fig. 4, B2).
zRemove the programming unit by lifting upward (Fig. 4, B3).
