indicate the type and seriousness of the ensuing risk if measures for
minimizing danger are not taken.
The following signal words aredefined and can be used in this document:
DANGER
DANGER indicates that severe or life-threatening personal injury will
occur.
WARNING
WARNING indicates that severe to life-threatening personal injury may
occur.
CAUTION
CAUTION indicates that minor to medium personal injury may occur.
NOTICE
NOTICE indicates that material damage may occur.
Important information
The info symbol indicates important information where there is no risk to
people or property.
1.2 General safety instructions
HNotice for the target group
These installation instructions are intended for
plumbers, heating engineers and electricians. All
instructions must be observed. Failure to comply with
instructions may result in material damage and
personal injury, including possible loss of life.
▶ Read the installation instructions (heat source,
heating controller, etc.) before installation.
▶ Observe the safety instructions and warnings.
▶ Observe national and regional regulations,
technical rules and guidelines.
HDetermined use
▶ Use the product only to control heating systems.
Any other use is considered inappropriate. We take no
responsibility for damage caused through incorrect
use.

2 Product information
This is an original manual. This manual may not be translated without the
approval of the manufacturer.
2.1 Declaration of conformity
The design and operating characteristics of this product comply with the
European and national requirements.
The CE marking declares that the product complies with all the
applicable EU legislation, which is stipulated by attaching this
marking.
The complete text of the Declaration of Conformity is available on the
Internet: worcester-bosch.co.uk
2.2 Product Description
The user interface HPC 410 controls max. 4 heating/cooling1) circuits
individually 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.
– 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.
• 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.
The functional scope and thus the menu structure of the user interface
are determined by the structure of the system. The adjustment ranges,
default settings and functional scope may differ from the information in
these instructions, depending on the system installed at the site.
Depending on the software version of the control unit, the texts shown in
the display may differ from the texts in this manual.
• If 2 or more heating/cooling1) circuits are installed, settings for each
heating/cooling1) circuit is available and are necessary.
• If special system components and modules are installed (e.g.
MS 200solar module,poolmodule MP 100), correspondingsettings
are available and necessary.
Control modes
The following main control modes are available for the heating system:
•Outdoor-temp.-compensated
– the flow temperature is adjusted based on the outside
temperature according to an optimised heating curve.
•Outdoor-temp.-compensated with low end
– the flow temperature is adjusted based on the outside
temperature according to a simplified heating curve.
For both of the control modes a room controller may be installed in the
reference room to allow the influence of the measured and required
room temperature. The heating curve is then adjusted accordingly.
If cooling is active, a set constant temperature is maintained.
2.3 Additional accessories
Function modules and user interfaces of the EMS 2 control system:
•User interface CR102) as a simple remote room controller.
•User interface CR10H as a simple remote room controller with
option to measure relative humidity (heating/cooling circuits).
•MM 100: module for one heating/cooling circuit with mixing valve.
•MP 1002): module for a swimming pool.
•MS 1002): module for solar DHW heating.
•MS 2002): module for advanced solar systems.
Combination is not possible with the following products:
• FR..., FW..., TF..., TR..., TA...
3 Commissioning
WARNING
Risk of scalding!
As DHW temperatures above 60 °C can be reached when the customer
activates the extra DHW function, a temperature mixing device must be
installed.
NOTICE
Floor damage!
The floor may be damaged due to excessive heat.
▶ 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 circulation pump and to one of the external
inputs.

done. The range and default values varies depending on
model of heat pump.
[Set on/off hysteresis of split outdoor unit in heating
mode.]:
50...1500 K x min
The heat pump starts when the flow temperature has been
below the set flow temperature for the set value. The heat

The heat pump stops when the flow temperature has been
below the set flow temperature for the set value. The heat
pump starts when the flow temperature has been above
the set flow temperature for the set value.
[Set on/off hysteresis in pool mode.]: 50...1500 K x min
The heat pump stops when the flow temperature has been
below the set flow temperature for the set value. The heat
pump starts when the flow temperature has been above
the set flow temperature for the set value.

two points: the base point (starting point of the heating curve) and the

Table 15 Basic settings of the simple heating curve
Heat constantly below a certain outside temperature
To prevent the system from cooling down, DIN-EN 12831 requires that,
for the maintaining of a comfortable heat, all heating surfaces and heat
sources are designed to a defined output. If the adjusted outside
temperature set under Constant heat below is undercut, the active
setback mode is interrupted by normal heating mode.
For example, if the settings Setback: Heating off : 5 °C and Constant
heat below: -15 °C are active, the setback mode is activated when the
adjusted outside temperature is between 5 °C and -15 °Cand the heating
mode is activated below -15 °C. This allows smaller heat emitters to be
utilised.
Frost protection limit temperature (outside temperature threshold)
Under this menu item the limit temperature for the frost protection

Outdoor temp or Room and outside temp. is set in the menu.
NOTICE
Domestic hot water carrying parts may be damaged beyond repair if
the frost protection limit temperature is set too low and in prolonged

▶ Only contractors are permitted to adjust the factory setting of the
frost protection limit temperature (5 °C).
▶ Do not set the frost protection limit temperature too low. Damage
caused by a low frost protection limit temperature is not covered by
the warranty.
▶ Set frost protection limit temperature and frost protection for all
heating circuits.
▶ To ensure frost protection for the entire heating system, set either
Outdoor temp or Room and outside temp. in the Frost prot. menu.
The setting Room temperature does not offer absolute frost protection,
because pipework installed in façades, for instance, can freeze. If an
outside temperature sensor is installed on the other hand, frost
protection can be assured for the entire heating system regardless of the

settings are only available if the system is designed and configured
accordingly. Default temperature settings depend on the installed heat
source.
CAUTION
Risk of scalding!
The maximum DHW temperature can be set above 60 °C and during
thermal disinfection the DHW is heated to above 60 °C.
▶ Inform all people concerned and make sure that a mixing device is
installed.
The DHW system is activated by default at delivery.
▶ If no DHW system is installed, deactivate DHW system in the
commissioning or in the DHW menu.
Perform thermal disinfection to kill off pathogens (e.g. legionella) on a
regular basis. In the case of larger DHW systems, there may be statutory
requirements for thermal disinfection.
