2 Product description
INFORMATION
The RoCon+HP1 controller is part of the indoor unit.
It consists of the switching panel RoCon BM2C PCB to
which the actuators and sensors as well as other
components in the regulating system are connected and
the RoCon+B1 control panel.
These operating instructions only explain the functions and
possible settings of the controller. More information on the
switch box and other equipment components can be found
in the supplementary documents.
The electronic, digital controller is able to automatically control all
heating and hot water functions for a direct HC, a storage loading
circuit and also further HCs via optionally connectible mixer
modules, depending on the heating device.
It performs all safety management for the indoor unit. This executes
a safety switch-off in the event of a water shortage or undefined
operating states. A corresponding error message shows the operator
all the information regarding fault causes.
All function settings for the indoor unit and the optional RoCon
devices that are connected via the data bus are undertaken with the
control elements of the integrated RoCon+ B1 control panel and
shown on the plain text display with coloured backlighting.
The following additional, optional devices can be connected to the
indoor unit via the controller data bus:
▪ RoConU1 (EHS157034) room station
▪ RoConM1 (EHS157068) mixer module
In addition, the RoCon+ HP1 controller has a freeze-up protection
function for the direct HC and the storage tank charging circuit as
well as an automatic function for heating support (integration of an
auxiliary heat source such as a wood-burning boiler or solar system).
The potential-free AUX switching contact can be used to carry out
different control functions in conjunction with external devices
(request from an external heat generator, changeover to bivalent
operation, external status indicator, etc.).
In addition, it also has several inputs for assessing external control
contacts (external operating mode switching or heat request, Smart
Grid and low rate EVU functions
The optional outdoor temperature sensor installed on the north side
of the building can be used to further optimise the weathercompensated leaving water temperature control.
If the optional RoCon G1 (EHS157056) gateway is installed and
connected to the Internet, the indoor unit can be conveniently
monitored and operated by remote control using a mobile phone
(app).
Initial commissioning of the heating system is described in the
installation instructions for the indoor unit.
Certain menu items of the RoCon+ HP1 controller are only
accessible to the heating expert. This security measure ensures that
no undesirable malfunctions arise during operation of the system
through incorrect settings.
All settings for the assigned HC can be made with the RoConU1
(EHS157034) room station in the same way as on the control panel.
If the terminal function is activated, all operating possibilities that are
available on the integrated control panel are available with the
exception of certain special functions (e.g. manual operation).
After appropriate assignment, a connected RoConM1 (EHS157068)
mixer module is also operated using the RoCon+ B1 control panel
and/or the RoConU1 (EHS157034) room station.

).
2.1 Temporary shutdown
CAUTION
A heating system that is shut down can freeze in the event
of frost and may suffer damage.
▪ Drain the heating system that is shut down if there is
danger of frost.
▪ If the heating system is not drained, the power supply
must be ensured and the external main switch must
remain switched on if there is a danger of frost.
If the heat pump is not required for a lengthy period, it can be
temporarily decommissioned.
However, we recommend not to disconnect the system from the
power supply but merely to switch it to "Standby mode"
The system is then protected from frost. The pumps and valve
protection functions are active.
If it is not possible to guarantee the power supply when there is
danger of frost,
▪ completely drain the indoor unit on the water side, or
▪ apply suitable antifreeze measures to the connected heating
system and hot water storage tank (e.g. draining).
INFORMATION
If there is only a risk of frost for a few days when the power
supply is not reliable, it is not necessary to empty the
indoor unit due to the very good thermal insulation,
provided that the storage tank temperature is regularly
monitored and does not fall below +3°C.
However, this provides no freeze-up protection for the
connected heat emitter.

3.1 General
DANGER: RISK OF ELECTROCUTION
If electrical components come into contact with water, this
can cause an electric shock as well as cause potentially
fatal burns or injuries.
▪ The displays and keys of the controller must be
protected against the effects of moisture.
▪ To clean the controller, use a dry cotton cloth. The use
of aggressive cleaning agents and other fluids can
cause damage to devices or lead to electric shock.
INFORMATION
The heat pump makes the most effective use of energy at
the lowest possible return and hot water target
temperatures.
If an external heat generator (e.g. the optional backup
heater) is activated at target leaving water temperatures
above 50°C, the efficiency (COP) of the heat pump can
deteriorate (depending on the outside temperature).

3.3.8 External operation
In addition to operation via the integrated RoCon+ HP1 controller,
the system can also be adjusted and operated via external devices.
Operation via the Internet
An optional (RoCon G1 (EHS157056)) gateway can be used to
connect the RoCon+ HP1 controller to the Internet. This enables
remote control of the RoCon+HP1 by mobile phone (using an app).
Operation via the room station
It can also be operated via the optional RoCon U1 (EHS157034)
room station. The operating elements and instructions for use are
described in the "Daikin RoCon HP, EHS157034, EHS157068
Operating Instructions " (available in digital form). All application
instructions are also valid for the indoor unit.
4 Function
The system fully automatically controls the operation of the room
heating, room cooling and domestic hot water preparation on the
sanitary side on the basis of the specifications set in the RoCon
+HP1 controller. The functions that can influence system operation
are described below.
Some of the functions and parameters described are restricted by
access rights and can only be set by a heating specialist (see
"4.5.1Access rights (technician code)"[416]).
4.1 Operating mode
[→Main menu →Operating mode]
This menu is used to select the operating mode for operating the
device. The current operating mode is indicated by a corresponding
symbol on the start screen.
Standby operating mode (Standby)
NOTICE
A heating system that is not protected against frost can
freeze in the event of frost and thus be damaged.
▪ Drain the heating system on the water side if there is a
danger of frost.
▪ If the heating system is not drained, the power supply
must be ensured and the mains switch must remain
switched on if there is a risk of frost.
In this operating mode, the indoor unit is switched to standby mode.
The freeze-up protection function remains unchanged. In order to
maintain this function, the system must not be disconnected from the
mains.
All controllers integrated in the RoCon system via the CAN bus are
primarily also switched to the "Standby" operating mode.
INFORMATION
In the "Standby" operating mode, the heat pump and the
optionally connected backup heater are disconnected from
the power supply (energy-saving mode) if the following
conditions are met:
▪ the outdoor temperature sensor is connected and
correctly parametrised in the system configuration
▪ the outside temperature is more than 8°C
▪ there is no heating request
▪ the freeze-up protection function is not active in any
connected HC and
▪ the indoor unit has been switched on for at least
5minutes.
Reduce operating mode
Reduced heating operation (lower room target temperature)
according to the set reduction temperature in the [Reduce room
temperature] parameter (see "4.2User"[412]).

INFORMATION: Switching contact for external
operating mode changeover
A potential-free switching contact connected to the "Ext"
terminals on connection J8 of the indoor unit and wired
with a resistor can also be used to change over from an
external device (e.g. modem, ...). See " 4‒1 Resistance
values for evaluating the EXT signal"[412].
In this case, the switching contact functionality is
dependent on the parameter [Func. burner blocking
contact]:
▪ [Func. burner blocking contact] = "Resistance
values" (default setting): Evaluation of the resistance
values.
▪ [Func. burner blocking contact] = "Burner blocking
contact": Evaluation as a burner blocking contact. If the
switching contact is closed, the external heat generator
has priority.
4‒1 Resistance values for evaluating the EXT signal
Operating mode Resistance Tolerance
Standby <680Ω ±5%
Heating 1200Ω
Reduce 1800Ω
Summer 2700Ω
Automatic 1 4700Ω
Automatic 2 8200Ω
INFORMATION
The resistances specified in " 4‒1 Resistance values for
evaluating the EXT signal" [4 12] in a tolerance field of
5%. Resistances outside this tolerance field are interpreted
as an open input. The heat generator switches back to the
previously active operating mode.
The input is not considered for resistance values greater
than the value for "Automatic 2".
If several switching contacts are connected to the indoor
unit (e.g. smart grid, room thermostat), the associated
functions may have a higher priority than the external
mode switching. The operating mode requested by the
EXT switching contact is then possibly not activated or is
only activated later.
Besides these operating modes, different temporary time programs
(see " 4‒2 Overview of temporary time programs" [4 12]) are
available that are carried out with priority after activation.

4.4.3 External heat sources
[→Main menu →Settings →Ext. source]
This menu can be used to configure the integration of an optional
external heat source.
The heat supplied by an alternative heat generator (WEZ) must be
fed to the unpressurised cylinder water in the hot water tank of the
indoor unit.
▪ On use of the optional EKBUxx backup heater, this is carried out
due to the design installation situation.
▪ When using an alternative WEZ (e.g. gas- or oil-fired boiler), this
can be hydraulically integrated:
▪ unpressurised via the connections (solar feed and solar return)
of the hot water storage tank or
▪ with Daikin Altherma EHS…B… and ETS…B… device types,
via the integrated pressure solar heat exchanger
The setting of the [Config. ext. heat source] parameter determines
whether and which additional heat generator (WEZ) is available for
domestic hot water preparation (DHW) and heating support (HZU).
▪ No external heat source
▪ Optional backup heater
▪ External heat source for DHW and heating support: Alternative
WEZ provides domestic hot water preparation and heating
support. To request the WEZ, relay K3 is switched for connections
X1-L1 and XBUH1-T1 on the RTX-EHS PCB.
▪ External heat source for DHW or HZU: Alternative WEZ 1
(optional EKBUxx backup heater) provides domestic hot water
preparation and alternative WEZ 2 provides heating support. To
request the WEZ 1, relay K3 (connections X1-L1 and XBUH1-T1)
is switched on the RTX-EHS PCB and to request the WEZ 2, relay

This menu can be used to adjust parameter for inputs and outputs of
the controller PCB to optimise the system controller individually.
Smart grid
WARNING
There is a danger of scalds at hot water target
temperatures over 65°C. This is possible because the
utility company (EVU) is entitled to control current draw
optimised according to supply and demand in the
definitions for Smart Grid.
Such forced charging can cause the hot water target
temperature in the hot water tank to exceed 65°C.
This storage tank charging is carried out even when
"Standby" operating mode is set.
▪ Install scald protection in the hot water distribution line.
To use this function, a special electricity meter with SG receiver to
which the heat pump must be connected is required.
As soon as the function is activated by the [Smart grid] parameter,
the heat pump is set to an operating mode as per the following table
depending on the utility company signal.

▪ Heat request for room heating or cooling requirement.
▪ Heat request for room heating or domestic hot water preparation.
▪ "Cooling" operating mode active.
Interlink function
Setting the [Interlink function] parameter = "On" provides the option
that the indoor unit includes two different leaving water temperature
setpoints in the controller.
This applies to both weather-compensated control and control
according to a fixed target leaving water temperature (see
"4.5Configuration"[416]).
One possible application is, for example, the additional integration of
an HP convector in a surface heating and cooling system.
Prerequisite: 2 switching contacts (e.g. room thermostats) are
connected to the plug connection J16 of the indoor unit.

4.4.5 Intelligent storage tank management
[→Main menu →Settings →ISM]
If the storage temperatures are high enough, the energy in the
storage tank can be used for room heating. This can either increase
comfort ([Continuous heating] function) or make it possible to use
energy from an external heat source, e.g. solar, when heating is
required ([Heating support (HZU)] function).
Continuous heating
The activated Continuous heating function ([Continuous heating]
parameter = "On") allows uninterrupted heating even during
defrosting of the evaporator. This enables high comfort to be
guaranteed, even with rapidly reacting heating systems (e.g.
convectors).
Heating support (HZU)
If the heating support ([Heating support (HZU)] parameter = "On") is
activated, the energy in the built-in storage tank of the indoor unit is
used to perform the heating function. If the storage tank temperature
is sufficiently high, the heat generation by the heat pump remains
out of operation.

INFORMATION
The weather-compensated leaving water temperature
control has no influence on the target leaving water
temperature in the case of a hot water circuit request.
With mixer module connected
The setting of the heating/cooling curves and the activation of the
weather-compensated leaving water temperature control for the
assigned HC are carried out in the same way as described above.
The assigned HC can be operated as a:
▪ Mixer add-on
The outside temperature of the outdoor temperature sensor
connected to the indoor unit external temperature sensor is
transmitted to the mixer module via the CAN bus.
or as a
▪ Mixer add-on with zone control
A separate outdoor temperature sensor must be connected to the
mixer module. The assigned HC is controlled according to the
outside temperature relevant for this zone.
If the terminal function is activated, the mixer module can be
operated and the settings for the assigned HC undertaken via the
RoCon+B1 control panel of the indoor unit.
In conjunction with the RoCon U1 (EHS157034) room station, the
mixer module can also control the assigned HC completely
autonomously and independently of the heat generator.
Further explanations and possible settings for this menu can be
found in "7.6Configuration"[437].
Freeze-up protection function
The integrated heating circulation pump is switched on at an external
temperature below the [Frost protection temperature] parameter
value in order to prevent the heating system from freezing.
In addition, the feed, storage and connected room temperature
sensors are also constantly monitored. If the temperature measured
by one of these sensors falls below 7°C (below 5°C at room
temperature), the antifreeze function is also activated.
If the heating leaving water temperature falls below 7°C, the heat
pump heats until the heating leaving water temperature reaches at
least 12°C.
The function is ended if the external temperature rises above the set
[Frost protection temperature] parameter value+1K and also there is
no other activation condition.
INFORMATION
Operation of the heat pump can be shut off completely for
a limited period of time by the utility company if the
following low-tariff functions are activated:
[HT/NT function] parameter = "Switch all off" or [Smart grid]
parameter = "On"
These situations can be recognised if, in the [→ Main

Heating curve
INFORMATION: Overheating and moisture protection
In the event of malfunction, the underfloor heating system,
the screed or the floor structure could be damaged due to
overheating.
▪ Prior to initial commissioning, set the maximum
temperature limit in the RoCon+HP1 controller ([Max.
feed temperature] parameter) to the maximum
permissible system temperature before the screed
drying starts.
▪ Connect an overheating protection switch (in the
building) at the "EXT" plug connection to external mode
switch-over so that the indoor unit is switched to
"Standby" or "Summer" mode. If the [Room thermostat]
parameter = "Yes" or [Interlink function] parameter =
"On", the overheating protection switch must be
connected so that the room thermostat's switching
contact is interrupted.
▪ If the underfloor heating is also used for room cooling,
the connection notes in the above point also apply to
the connection of a moisture protection switch in the
building.
The heating curve is used to adapt the leaving water temperature to
the characteristics of the building independent of the respective
outside temperature (weather-compensated leaving water
temperature control, see "4.5 Configuration" [4 16]). Generally
speaking, the slope of the heating curve describes the ratio of the
leaving water temperature change to the external temperature
change.
The heating curve is valid within the limits of the minimum and
maximum temperatures set for the respective HC. Deviations may
occur between the room temperature measured in the occupied area
and the desired room temperature; these can be minimised by
installing a room thermostat or a RoCon U1 (EHS157034) room
station.
The controller is set at the factory in such a way that the heating
curve does not independently adjust itself during operation.
The automatic heating curve adjustment can be activated
([Heating curve adaptation] parameter) if the outdoor temperature
sensor and the room station (RoCon U1 (EHS157034)) are
connected (see "4.5Configuration"[416]).
Start conditions for automatic heating curve adjustment:
▪ Outside temperature<8°C
▪ Operating mode is "Automatic 1" or "Automatic 2"
▪ Duration of the setback period is at least 6h
If no automatic heating curve adjustment is activated, the heating
curve can be manually adjusted by adjusting the [Heating curve]
parameter).

Comfort heating
If the heat pump cannot cover the heating demand when outside
temperatures are very low, heat is extracted from the storage tank
and used for room heating. In rare cases (in systems with high
required leaving water temperatures and low required hot water
temperatures), the required leaving water temperature can be higher
than the storage tank setpoint temperature. In order to avoid shortterm loss of comfort in heating operation for these systems, the
[Comfort heating] parameter can be set to "On". At corresponding
outside temperatures, the storage tank temperature is raised above
the storage tank temperature set for the hot water requirement.
INFORMATION
If [Comfort heating] is set to "On", the power consumption
of the heat pump may increase. In the default setting,
[Comfort heating] is set to "Off".
Detailed explanations and possible setting values of this function can
be found in "7.6Configuration"[437].
4.5.5 Cooling
[→Main menu →Configuration →Cooling]
This menu is used to make settings for cooling operation.
INFORMATION: Danger of condensation
In the event of malfunction or incorrect parameter settings,
the underfloor heating, the screed or the floor structure
could be damaged due to condensation.
▪ Prior to initial commissioning and activation of cooling
operation, set the minimum temperature limit to the
minimum permissible system temperature in the RoCon
+ HP1 controller ([Feed temperature lower limit]
parameter).
To protect against moisture damage caused by cooling, a moisture
protection switch can be connected to the plug connection J8
"EXT" (see "4.5.4Heating"[417]).
Prerequisites for cooling operation:
▪ Outside temperature > set value of room target temperature
▪
Outside temperature > set value of the [Start cooling outside
temp.] parameter
▪ "Cooling" operating mode activated.
▪ via menu "Operating mode" or
▪ via room thermostat function (cooling switching contact closed)
▪ No heat request active in the heating system's RoCon system.
INFORMATION
If the mean outside temperature falls below 4°C when
"Cooling" operating mode is active, the operating mode
automatically switches to "Heating".
Renewed automatic operating mode changeover to
"Cooling" only takes place:
▪ if a room thermostat is connected to plug connection
J16 (cooling) and
▪ the room thermostat's switching contact is closed and
▪ the mean outside temperature increases to over 10°C
again.
Cooling curve
[→Main menu →Configuration →Cooling →Cooling curve]
The cooling curve determines the target leaving water temperature
in cooling operation depending on the respective outside
temperature. (for weather-compensated leaving water temperature
control, see "4.5.3HC config." [416]). Warmer outside temperatures
result in a colder target leaving water temperature and vice versa.
The cooling curve can be adapted to the condition of the building by
four parameters (see " 4‒3 Cooling curve parameter
dependency"[419]).
1 [Start cooling outside temp.]
2 [Max. cooling outside temp.]
3 [Target flow cooling, start]
4 [Target flow cooling, max.]
Cooling parameters

[→Main menu →Configuration →DHW]
The domestic hot water preparation can be individually adapted to
the behaviour and requirements of the users in this menu. This
minimises energy consumption and increases comfort.
Solar function
The [Solar function] parameter is used to reduce the target
temperature of the hot water storage tank in order to increase the
yield of a connected solar system. The setpoint of the hot water
temperature is set as a function of the outside temperature and in
compliance with the safety functions. In addition, the following
parameters are defined: [Hot water hysteresis] = 5 K; [Building
insulation] = "Normal"
To activate the solar function, it must be set in the menu [→Main
menu → Configuration →DHW → Solar function] to "On" and the
switching contact connected to the plug connection J8 (EXT) must
be closed..
Settings for optional circulation pump
Depending on the [Circulation pump control] parameter, an optional
circulation pump can be controlled synchronously with the selected
time program for domestic hot water preparation or with the time
program for the circulation pump (see "4.3 Time program" [4 13]).
During the release times of the selected time program, the
circulation pump can be operated either continuously or cycled. This
is defined with the [Circulation pump interval] parameter.
Anti-legionella protection
This function is used to prevent bacterial contamination in the hot
water tank by thermal disinfection. To do so, the hot water tank is
heated 1× daily or 1× weekly to the disinfection temperature [Antilegionella temperature] depending on the [Anti-legionella day]
parameter. Disinfection starts at the specified start time [Antilegionella start time] and is active for one hour. An optionally
connected circulation pump is automatically switched on during this
time.

By activating the air purge function, the controller starts a fixed
defined sequence program with start/stop operation of the integrated
heating circulation pump and various positions of the integrated 3way changeover valves. Existing air can escape during operation via
the automatic air purge valve.
INFORMATION
The activation of this function does not replace correct
venting of the HC.
The HC must be completely full before activating this
function.

[→Main menu →Configuration →Addition →Relay test]
This program allows testing of internal switching relays. This may be
necessary in the event of malfunctions, error messages or as part of
annual maintenance. When the menu is opened, all relays are
deactivated. Selecting one or more relays activates them. When the
menu is exited, all relay tests are terminated.
The relay test menu is operated in the same way as list entries (see
"3.3.3 Navigating in lists and selecting list entries"[48]). However,
several relays can be activated in parallel in the relay list for testing.
To do this, select the corresponding relay with "OK". Activated relays
are indicated by a tick.
Screed drying
[→Main menu →Configuration →Addition →Screed]
The screed drying is started in the menu according to the settings in
[Screed program]. The program is used exclusively for the
prescribed drying of newly created screed for underfloor heating
systems. The first day of the screed program begins after activation
of the program at the change of day at 00:00.
Screed drying is a special function and is not interrupted by any
other operating mode. It can only be activated by the heating expert
for the direct HC and/or optionally connected mixed HCs. It must be
activated separately for each HC.
INFORMATION
Before starting the screed drying, the [Room thermostat]
and [Interlink function] parameters must be deactivated.
During a short-term power failure, a previously activated
screed drying is continued at the point of the interruption.
After activation of the screed drying, all weather-compensated
control functions of the respective HC are switched off. The
respective HC works as a constant temperature control regardless of
the operating mode and switching times.
Already activated screed drying can be deactivated at any time. After
ending the screed drying, the parameter is automatically set to "Off"
and the HC works according to the currently set operating mode
again.

Typical screed programs
Function heating
The function heating serves as proof of the production of defect free
work for the heating engineer. A prefabricated heating protocol
related to underfloor heating can be found in the Internet portal of
the manufacturer.
In this sense, the function heating (identical with "Heating" in
EN 1264, section 5.2) is not considered as a heating process to
achieve workability of the screed. Generally, a special screed curing
heating and/or mechanical drying is required for this.
The heating of cement screeds should be carried out at the earliest
after 21days and of anhydrite screeds after 7 days at the earliest in
accordance with the specifications of the manufacturer. The first
heating begins with a leaving water temperature of 25°C that must
be maintained for 3days. Afterwards, the heating is carried out with
the maximum set leaving water temperature for the HC (limited to
max. 55°C), which must be maintained for a further 4days.
Due to the insulating effect of the DUO heating pipe for System 70,
the screed function must be carried out at higher temperatures. The
temperature profile must be adapted in the [Screed program]
parameter for this use case. For System70, the heating begins at a
temperature of 38°C that is maintained for 3days. The set maximum
HC temperature (limited to 70°C) is then maintained for 4 days.
After the described heating process, it is not yet assured that the
screed has reached the required moisture content for workability of
the screed.
The moisture content in the screed must be checked by
measurement prior to laying the surface covering.
INFORMATION
Procedure in accordance with EN1264 Part 4:
For anhydrite and cement screeds, the HCs must be leak
tested by a water pressure test after completion. The
leaktightness must be ensured immediately before and
during the laying of the screed. The height of the test
pressure is at least 1.3x the maximum permitted operating
pressure.
Suitable measures must be taken if there is a risk of
freezing, e.g. use of antifreeze agents or heating the
building. If antifreeze agents are no longer necessary for
the intended operation of the system, the antifreeze agent
must be removed by draining and rinsing the system with
at least 3 changes of the water.

function heating

tVLeaving water temperature
Z Duration of the screed function in days after starting the
function
Screed curing heating
The drying process for the screed cannot be exactly predicted. If
there is a high degree of humidity, sometimes it can stop completely.
The drying process can be speeded up by activating the underfloor
heating (screed curing heating) or measures such as mechanical
drying.
Each screed curing heating must be ordered separately by the client
as an extra service in accordance with German construction contract
procedures (VOB). The workability of the screed is a prerequisite for
the top floor installer to start work so that he can produce defect free
work.
With standard settings, the combined function and screed curing
heating program can be activated to achieve the required residual
moisture in the screed for workability of the screed (see " 4‒6
Chronological sequence of the screed program during the combined
function and screed curing heating" [4 21]). However, the residual
moisture of the screed must basically be checked metrologically
before the flooring can be laid.

Functional IDs
The RoCon system offers a very wide range of application and
extension options. The individual RoCon system components
communicate via the CAN data bus. To do this, the RoConBM2C
PCBs and the RoCon+B1 control panels of the indoor unit and, if
necessary, the optional RoCon U1 (EHS157034) room station
system components and RoConM1 (EHS157068) mixer module are
connected to each other via data bus cables. These system
components must be allocated unique functional IDs, so that the
data exchange and the assignment within the RoCon system
functions without any problems.
The easiest way to assign the functional identifiers is to use the
Configuration Wizard. This is carried out automatically during the
first commissioning or can be started manually in case of extensions
in the heating system in [→Main menu →Configuration →Wizard].
In addition, most identifiers can also be adapted to the RoCon
system by parameter settings in this menu.

4 Function
4.8.1 Selecting the terminal address
[→Main menu →Terminal →Address]
Setting of the terminal ID of the control panel for system access. The
set value must be unique throughout the entire system. Confirmation
of this parameter with the rotary button effects a new initialisation of
the controller.
All settings except "Off" authorise the user of the control panel to
activate the terminal function and thus to operate all RoCon system
components with a valid device ID.
4.8.2 Bus scan for terminal function
[→Main menu →Terminal →Bus scan]
After activating the "Bus scan", a list of detected devices (with
assigned terminal address) is displayed in the menu [→ Main menu
→Terminal] for selection. After selecting and confirming an external
device, the terminal function for this device is activated. The control
panel is then in terminal operation.
The local control panel acts as a remote controller for the external
device and the corresponding start screen is shown on the display.
In this case, all the control functions are performed and saved 1:1 in
the same way as on the external device. The displayed values and
symbols are always taken over by the selected device.
To operate the local device, switch to the start screen of the external
device. Press and hold the rotary switch to return to the menu of the
local device.
INFORMATION
To perform the bus scan, a valid terminal address must be
assigned to the RoCon+B1 control panel of the indoor unit
or the RoConU1 (EHS157034) room station. This can only
be done with a specialist code. Contact your heating expert
in this regard.
If the terminal function is to be used in the heating system,
the terminal ID = 0 ([Terminal address] parameter = "0")
must be assigned to a control panel.
Example: Activate terminal operation for the heat generator with bus
identification 2 [→Main menu →Terminal →Bus scan]:
The bus scan is carried out. An overview of all devices that are
found is displayed.
1 Turn the rotary switch clockwise until the BM1/BE1 #2 controller
is displayed in blue.
2 Briefly press the rotary button to confirm ("OK").
Result: The local control panel acts as a remote controller for
the heat generator with bus ID 2.
To end terminal operation and switch the control panel back to the
operation of the assigned device, switch to the start screen of the
external device. Press and hold the rotary switch to return to the
menu of the local device.
INFORMATION
If the local control panel is used as a remote controller for
a mixer module, both the standard screen and the menu
structure are changed (see "9Mixer module"[448]).
4.9 Statistics
INFORMATION
The values listed in this menu are approximate values. In
particular if glycol is present in the system, there may be
greater deviations from real performance data.
[→Main menu →Statistics]
This menu can be used to access the values for the power output
and run times of the heat pump and its components. The [Electr.
energy total] parameter describes the total electrical power input of
the heat pump and its components. All other values refer to the
energy provided by the heat pump or the run time of various
components.
4.9.1 Month
[→Main menu →Statistics →Month]
This menu can be used to call up summed values for the power
output and power input over the month. The displayed value is
assigned to the month shown in blue on the diagram. The various
values can be displayed by turning the rotary switch.
4.9.2 Total
[→Main menu →Statistics →Total]
This menu can be used to call up summed values for the power
output and power input of the heat pump since commissioning (or
since the last reset by a specialist).

8 Errors and faults
DANGER: RISK OF ELECTROCUTION
Electrostatic charges can lead to voltage arcing that can
destroy the electronic components.
▪ Ensure potential equalisation prior to touching the
switching panel PCB (e.g. by touching the switching
panel holder).
The electronics of the indoor unit indicate an error by red illumination
of the status indicator, the appearance of the error screen on the
display (see "8.4 Error screen" [4 48]) and the appearance of the
error symbol on the start screen. An integrated error memory stores
up to 15 error messages (see "8.3Error protocol"[447]).
INFORMATION
A list of all error codes can be found in the reference guide
for the installer, chapter "Errors and faults".
Troubleshooting: Error code E90XX
An error reset can be performed. This can be started from the
currently displayed error screen. If the error screen has been exited,
it can be recalled via [→Main menu →Error →Screen].
If the same error is displayed again shortly, the cause of the error
must be found and rectified by a specialist. In the meantime,
emergency operation may be maintained. Emergency operation can
be permitted via [→ Main menu → Error → Emergency], see
"8.1 Emergency operation" [4 47]. If emergency operation has not
been permitted ([Emergency] parameter = "No"), it can be started
from the current error screen.
Troubleshooting: Other error codes
The cause of the error must be found and rectified by a specialist. In
the meantime, emergency operation may be maintained. Emergency
operation can be permitted via [→ Main menu → Error
→Emergency], see "8.1 Emergency operation" [447]. If emergency
operation has not been permitted ([Emergency] parameter = "No"), it
can be started from the current error screen.
INFORMATION
To ensure that the error has not been caused by incorrect
settings, set all the parameters back to the factory settings
before possible replacement of components (see
"4.5.9Parameter reset"[421]).
If it is not possible to determine the cause of the fault,
please consult a service technician.
Please have the essential device data ready for this:

8.1 Emergency operation
[→Main menu →Error →Emergency]
If the heat pump fails, the backup heater or another external heat
generator can be used as an emergency heater. If [Emergency] is
set to "Yes", emergency operation is automatically activated in the
event of an error. Otherwise, emergency operation can only be
started in the event of an error via the error screen.
If emergency operation is started via the error screen, the
[Emergency] parameter remains set to "Yes", i.e. emergency
operation is also started automatically in the event of future errors. If
this is not desired, the [Emergency] parameter must be reset to "No"
after the error has been corrected.
8.2 Manual operation
[→Main menu →Error →Manual operation]
In manual operation, the heat pump is controlled to a fixed leaving
water temperature. Manual operation should only be used for
diagnostic purposes. Manual operation is started by setting the
[Manual operation status] parameter to "Active". The desired leaving
water temperature is set by [Temperature, manual operation]
parameter.
With hydraulically controlled priority operation for domestic hot water
preparation, it must be ensured that the target leaving water
temperature set in manual operation is sufficient to achieve the
stored hot water target temperature ([Hot water temperature target 1]
parameter).
8.3 Error protocol
[→Main menu →Error →Protocol]
The error protocol can be read in this menu. The most recent error
message comes first. All previous messages are moved backwards
with each new entry in the position. The 16th error message is
deleted if a new error message arrives. The error protocol can only
be deleted by a service specialist.

9 Mixer module
In addition to the direct HC, the heating system can be extended by
additional HCs using RoCon M1 (EHS157068) mixer modules.
These additional HCs can be configured independently of the direct
HC. The configuration is similar to the configuration of the direct HC
(see "4 Function"[4 11]). Only a limited selection of parameters and
functions is available (see "9.2 Mixer valve parameter
overview"[449]).
The optional RoConM1 (EHS157068) mixer module does not have
its own control unit. For configuration and operation, it must be
connected via a CAN bus line to the RoCon+ HP1+ controller
installed in the heat generator or a RoConU1 (EHS157034) room
station. The mixer module can be operated in terminal mode from
both operating units (see "4.8Terminal"[422]).
A unique device ID (≥1) must be set on the address switch of the
mixer module (see " 9‒1 Setting the device ID for the RoConM1
(EHS157068) mixer module" [4 48]) for the HC to be controlled by
this mixer module, which must be synchronised with the [Heating
circuit assignment] parameter of the mixer module (see " 4‒6
Functional IDs in the RoCon system"[422]]).
9‒1 Setting the device ID for the RoConM1 (EHS157068) mixer

9.1 Mixer module start screen (terminal function)
9‒3 Mixer module start screen
1 Mixer circuit leaving water temperature
The start screen for the mixer module (" 9‒3 Mixer module start
screen"[449]) is a reduced version of the RoCon+B1 start screen.
The meaning of the icons corresponds to " 3‒3 Display icons on
the start screen"[47], but the mixer circuit leaving water temperature
is the only system temperature displayed.
The start screen for the mixer module is displayed in the menu
[→Main menu → Terminal → Mixer #X]. Briefly pressing the rotary
switch switches to the mixer menu. A long press of the rotary switch
switches to the menu of the local control panel.

Operating mode Request by the user or controller for the function of the heat generator (e.g. room heating, domestic hot water
preparation, standby, etc.)
Backup request Operating situation in which the required leaving water temperature cannot be reached efficiently or at all
using the heat pump process. A heater booster (e.g. a backup heater) is therefore integrated to support the
heat pump in generating heat.
Backup heater Optional electric heater booster for general support of the heat pump during heat generation.
Heating curve Mathematical relationship between the outside temperature and the target leaving water temperature in order
to achieve the required room temperature at all outside temperatures.
Refrigerant A substance used for heat transfer in the heat pump process. At low temperature and low pressure, heat is
absorbed (refrigerant evaporates) and at higher temperature and pressure, heat is released (refrigerant
condenses).
Anti-legionella protection Periodic heating of the storage water to >60°C for the preventative elimination of pathogenic bacteria (so-
called legionella) in the hot water circuit.
