Applicability Of The Technical Documentation; Disposal; Installation; Types Of Installation - Bosch WORCESTER Sense II Installation Instructions Manual

Installation

Combination is not possible with the following products:
• FR10, FR10, FW100, RC25, RC35, ISM or SC controls
Applicability of these instructions to EMS 2-capable
modules
These instructions also apply to the controller when used in
conjunction with the heating circuit module MM 100/MM 200
(accessory).
Additional setting options may be found in some menus, if your
heating system is equipped with alternative modules (e.g. solar
module MS 100 (accessory)). These setting options are
explained in the technical documentation of the modules.

Applicability of the technical documentation

Information in the technical documentation about heat
sources, additional controls or modules also apply to the
Sense II.

2.10 Disposal

▶ Dispose of packaging in an environmentally responsible
manner.
▶ When replacing a product or a component, dispose of the
old product or component in an environmentally
responsible manner.
3 Installation
The detailed system schematics for mounting the hydraulic
assemblies and components and the associated controls can
be obtained from your Local Commercial Sales Manager
(Commercial installations only).
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 controls and modules from the mains
voltage across all poles. Guard against
unintentional reconnection.

Types of installation

The use of the programming unit and the structure of the overall
system determine how the programming unit should be
installed ( Section 2, page 4).

Installation location of the user interface

If the weather-compensated control (without room
temperature influence) is active, for direct and easy access we
recommend the installation of the controller in the living space.
Alternatively, the controller can also be installed at the heat
source.
The room in your home where the controller is installed is
known as the reference room. If the room temperature-
dependent control is active, the room temperature in this room
serves as the target temperature for the entire system.
If the weather-compensated control with influence of the room
temperature is active, the room temperature functions as an
additional temperature input.
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 ( Fig. 4,
page 9).
• If remote controls are used for all heating circuits e.g.
Sense I, the main controller can be installed in the heat
source.
When using thermostatic radiator valves in the reference room:
▶ Open the thermostatic radiator 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.
If there is no suitable reference room, we
recommend converting the system to weather-
compensated control instead.
