Installation

Sense II – 6 720 818 367 (2015/10)

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.

2.9

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.

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).

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 (

 Section 2, page 4).

3.2

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.

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.

If there is no suitable reference room, we 
recommend converting the system to weather-
compensated control instead.
