3 Product information
3.1 Product description
• The user interface is used to control a heating system with a
maximum of four heating/cooling circuits and a cylinder primary
circuit for DHW heating, solar DHW heating and solar central heating
backup.
The user interface incorporates a time program:
- Heating systems: For each heating circuit, 2 time programs with
2 switching times per day. If a buffer cylinder is not installed,
heating circuits 2 ... 4 can only switch to heating mode when
heating circuit 1 is in heating mode.
- Domestic hot water: One time program for DHW heating and one
time program for the DHW circulation pump, each with 6
switching times per day.
The user interface displays information about the heat source and
heating system and is used to change the settings.
After operating for 1'h hour, the user interface has a power reserve
of at least 8 hours. If the power failure lasts longer than the power
reserve, the time and date will be deleted. All other settings are
saved.
• The functional scope and thus the menu structure of the user
interface are determined by the structure of the system. Your
attention is drawn to the importance of the system structure in the
relevant places. The adjustment ranges and default settings may
differ from the information in these instructions.
Certain menu items are specific to certain countries and are only
displayed if the country in which the heat pump is installed has been
set accordingly on the user interface.
3.1.1 Control types
The following main control types are available for the heating system:
• Weather-compensated: Automated control of the flow temperature
based on the outside temperature.
Weather-compensated with the influence of the room
temperature: Automated control of the flow temperature based on
the outside temperature and room temperature. Installation of a
remote control in the reference room is required.
If cobling is active, a set constant temperature is maintained.
Observe the further information on the control types and settings that
affect how the system is controlled (7 Chapter 6.3, page 17) .
3.2 Important notices on usage
&
WARNING: Risk of scalding!
I
If
t~ermal
disinfection ha. s been activated to avoid
• legion ella, the hot water
IS
heated once to in excess of
65 ·C. The factory setting for the hot water temperature
is 60 ·C. There is a risk of scalding at the draw-off points
if the temperature is set higher than this.
~ Make sure that a mixing device is installed.
&
NOTICE: Floor damage!
I
~
For underfloor heating systems, make sure that the
• maximum temperature for the floor type in question
is not exceeded.
~
If necessary, connect an additional temperature
switch at the voltage input of the respective pump or
to one of the external inputs of the heat pump.

3.3 Additional accessories
For precise information regarding suitable accessories, refer to the
catalogue.
Function modules and user interfaces of the EMS 2 control system:
• User interface
CR 10
as simple remote control
User interface CR 10 H as simple remote control with option to
measure relative humidity (heating/cooling circuits)
MM 100: Module for heating/cooling circuits with mixing valve
MP 100: Module for a swimming pool with heating via the heat pump
MM 100: Module for solar DHW heating
• MS 200: Module for extended solar systems.
Applicability of these instructions to EMS 2-capable modules
These instructions also apply to the user interface when used in
conjunction with heating/cooling circuit module MM 100 (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.
