1.2Safety instructions
Installation and commissioning
B Observe all instructions to ensure satisfactory operation.
B Read and observe the safety information and codes of conduct.
B Installation and commissioning must only be carried out by qualified and trained system installers.
Use
B Always use this device correctly and in conjunction with the stated control systems.
B Observe all regulations, standards, and codes applicable to installation and operation of the
system in your country.
Risk of death from electric shock
B The electrical supply must be connected by a qualified electrician. The terminal diagram must be
followed.
B Before installation: isolate all poles of the power supply (120 V AC).
B Do not install this device in rooms with high moisture exposure (e.g. bathrooms, saunas).
B Never directly connect this device to the 120 V AC power mains.
Risk of scalding at the taps
B Make sure that a thermostatic mixing valve is installed and that it is set to temperatures below
122 °F (50 °C).
Warning: frost
The heating system can freeze up in cold weather, if switched OFF or locked out.
B Leave the heating system permanently switched ON.
B Enable frost protection.
B In the event of a fault: remedy the fault immediately.
Warning: device damage
The RC35 has no field serviceable parts inside. Attempt to open the housing will cause internal
damage, render the device inoperable, and void the manufacturer's warranty.
B In case of system irregularities please consult the 7 "Diagnosis" and 10 "Troubleshooting"
sections of this manual.

2Product description
2.1Correct 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).
2.2Certifications
This product has been tested and is certified for both the US and Canadian markets,
and meets all applicable US and Canadian standards.

2.5Applicability of these instructions for function modules
(accessories)
These instructions also apply to the user interface when used in conjunction with the MM10 mixing
module and the WM10 low loss header module.
If the heating system is equipped with other function modules (e.g. SM10 solar module), additional
settings and menus become available. Please see the instructions included with the module for
details.
2.6Accessories
For detailed information on suitable accessories, refer to the catalogue.
•MM10 mixing module for controlling a 3-way mixing valve
•WM10 low loss header module
•Solar module and other EMS modules
•Outdoor temperature sensor, separate room temperature sensor

3.1Choosing 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.
3.2Types 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.

3.3Installation and connection
Please use only the wall bracket with screw terminals.
B If a wall bracket without screw terminals is already installed, replace it.
The wall bracket can be attached directly to the wall.
B Mount the wall bracket (Æ Fig. 3, left).
B Connect the two-wire bus cable from the Energy Management System (EMS) to the “RC” cable
terminals (Æ Fig. 3, [3]).

4“EXT” terminals for external room temperature sensor or for jumper
B If the RC35 is operated without an external room sensor, a jumper is needed on the “EXT”
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.
