•
MS 200
: module for advanced solar systems (wall-
mounted installation only).
Combination is not possible
with the following products:
•
FR..., FW..., TF..., TR..., TA...
Applicability of these instructions to EMS 2-capable
modules
These instructions also apply to the user interface when used in
conjunction with heating circuit module MM 100 and MM 200
(accessory).
Additional setting options may be found in some menus, if your
heating system is equipped with alternative modules (e.g.
MS 100 solar module, accessory). These setting options are
explained in the technical documentation of the modules.
2.9
Applicability of the technical documentation
Information in the technical documentation about heat
sources, heating controllers or the 2-wire BUS apply also to the
present user interface.
2.10 Disposal
▶ Dispose of packaging in an environmentally responsible
manner.
▶ When replacing an assembly or a component, dispose of
the old assembly or component in an environmentally
responsible manner.

Installation
The detailed system schematics for mounting the hydraulic
assemblies and components and the associated control
devices can be found in the planning documents or tender
specifications.
3.1
Types of installation
The use of the programming unit and the structure of the overall
system determine how the programming unit should be
installed (
Æ
Section 2, page 4).
3.2
Installation location of the user interface
If the weather-compensated control (without room
temperature influence) is active, for a direct and easy
accessible operation we recommend the installation of the user
interface in the living space. Alternatively, in case of this
control type the user interface can also be installed at the heat
source.
The room in your home where the user interface (as controller)
is installed is the reference room. If the room temperature-
dependent control is active, the room temperature in this room
serves as the reference variable for the entire system.
If the weather-compensated control with influence of the room
temperature is active, the room temperature functions as an
additional reference variable.
In case of room temperature-dependent control and weather-
compensated control with influence of the room temperature
the control quality depends on the installation location.
•
The installation location (= reference room) must be
suitable for controlling the heating system
(
Æ
Fig. 4, page 9).
•
The user interface must be installed on an interior wall.
•
If remote controls are used for all heating circuits, the user
interface can be installed in the heat source.
When using manual valves with factory default in the reference
room:
▶ Set the output of the radiators as low as possible.
In this way, the reference room will be heated identically as
the remaining rooms.
When using thermostatic valves in the reference room:
▶ Open the thermostatic valves completely and set the
output of the radiators as low as possible using adjustable
return fittings.
In this way, the reference room will be heated identically as
the remaining rooms.
WARNING:
Risk of scalding!
If DHW temperatures above 60 °C are set or
thermal disinfection is switched on, a mixer
must be installed.
DANGER:
Risk of electric shock!
▶ Before installing this product:
Disconnect the heat source and all other
BUS nodes from the mains voltage across
all poles.
If there is no suitable reference room, we
recommend converting the system to mere
weather-compensated control instead.
