Important Information and User Instructions1
General introduction1.1
emcotherm control technology offers products that are individually
harmonised to the needs of the convector market. This technology
has been developed in an environmentally-friendly and effective way
according to the latest state of technology.
Centralised and decentralised controlled and set switching functions
allow emcotherm control technology to be matched perfectly to the
product interfaces of leading manufacturers of convectors.
emcotherm control technology primarily consists of the following
components:
Connection box with integrated control board→
In emcotherm floor convectors, the connection box is installed in→
the convector at the factory and is ready for connection (see chapter
“Electrical Connection“ in the accompanying emcotherm convector
manual)
Components for individual room temperature control (see chapter →
in this manual)
Accessories for control components (see chapter  in this manual)→
Recommended uses and operation of emcotherm control components
can be found on the following pages of this manual.
Why you should read this manual1.2
This manual has been prepared to the best of our knowledge. In
particular this manual describes the areas of use, operation and
proper installation of the various emcotherm control components. It
should make the operator, user and maintenance personnel familiar
with the setup, functions, operation and maintenance as well as the
safety factors of these control components. This manual also contains
important information and descriptions for professional fitting and
installation of the emcotherm control components when used with
emcotherm convectors. It is therefore mainly intended for trained and
qualified personnel.
Please keep this manual in a safe place, so that you can refer to it
whenever necessary. Also be sure to pass this user information on to
subsequent owners.

Safety Information2
Safety-conscious operation2.1
The highest level of safety and a high standard of quality are a matter
of course to us, which is why all emcotherm control components have
been developed, manufactured and tested according to the latest
applicable norms, standards and directives.
Safe operation of emcotherm control components and the devices
connected to them can only be guaranteed if the control components
and connected devices are in a technically correct condition and are
used in a safe and aware manner according to their intended use!
For your own safety, we strongly recommend that you read and adhere
to all safety instructions in this manual as well as those in the manual
of connected devices (convector) before fitting, installing, operating
and using the emcotherm control components.
Personnel qualification2.2
In normal operating situations it is assumed that both emcotherm
control components and connected devices (convectors) are properly
fitted, electrically installed and ready for operation. Basic operation
and setting functions of the emcotherm control components can
be executed by semi-skilled and trained personnel according to the
directions in this manual.
All activities that go beyond simple operating and adjusting functions
such as fitting, installation, error / fault remedying and repairs must be
carried out by trained and qualified specialists.
DANGER !
DANGER !
All electrical installations, connecting, and disconnecting the
emcotherm control components may only be carried out by electrical
specialists* in compliance with the electrotechnical regulations.
* Definition of an electrical specialist as per:
Regulations for the Prevention of Industrial Accidents- Electrical
Systems, BGV A and
German Low Voltage Connection Ordinance (NAV)
Non-observance of this information can lead to death or serious→
bodily injury.
Competency and authorisation of personnel are to be determined by
the operator.

temperature control components
Install the room thermostat together with the speed controller→
preferably on an inside wall and across from the heating source in
the room.
Install approx. . m above the floor→
Select an installation site that is not close to open doors, windows→
or outside walls
ATTENTION !
ATTENTION !
Attention! Convective air should be able to reach the controller with no
obstruction, meaning to avoid installing the controller behind a curtain
or between shelving or other similar barriers.
Do not expose the controller to direct sunlight and do not install near
lamps, heaters, heating pipes, fireplaces or other electronic devices (TV,
PC etc.), which could emit heat.
When installing a combination of speed controller (DZR) and room
thermostat (RT), we recommend mounting the RT under the DZR

Short description emcotronic II3.5.2
The room thermostat displays the current operation mode:
Heating mode:→red LED illuminated
Cooling mode:→yellow LED illuminated
When the red and yellow LED are not illuminated, set-point and→
actual temperature correspond. Neither heating nor cooling is
taking place, the valves are not being triggered.
Use the occupancy button to switch between ‘room occupied’ and
‘room unoccupied’
‘Room occupied’: (→green LED illuminated) means comfort mode,
controlling according to the set value.
‘Room unoccupied’: (green LED off) means economy mode.→
When heating, the mode will operate at  K less and when cooling
at  K more.
The following operation states are possible:

Setting the set-point temperature with emcotronic II3.5.3
The desired room temperature (set point temperature) can be set using
the adjusting knob.
The maximum and minimum adjustable set point temperatures
(possible setting range) can be limited mechanically through the use of
a limiting pin.
Do this to limit the setting range: mechanical maximum value limit
