2 Product description

2 Product description

INFORMATION

The RoCon+ HP controller is part of the Daikin Altherma
ETS(X/H).

It consists of theswitching panel PCB RoCon BM2Cto
which the actuators and sensors as well as other compon­ents in the regulating system are connected and the oper­ating unit RoCon+ B1.

These operating instructions only explain the functions and
possible settings of the controller. More detailed informa­tion on other device components can be found in the other
applicable documents.

The electronic, digital controller is able to automatically control all
heating and hot water functions for a direct heating circuit, a storage
loading circuit and also further heating circuits via optionally connect­ible mixer modules, depending on the heating device.

It undertakes all safety management for the Daikin Altherma ETS(X/
H). In the event of a water shortage or undefined operating states,
this executes a safety switch-off. A corresponding error message
shows the operator all the information regarding fault causes.

All function settings for the Daikin Altherma ETS(X/H) 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
Daikin Altherma ETS(X/H) via the controller data bus:

▪ Room controller EHS157034
▪ EHS157068 mixer module
In addition, the RoCon+ HP controller has a frost protection function

for the direct heating circuit and the storage tank charging circuit as
well as an automatic function for heating support (integration of an
additional 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, switching to bivalent operat­ing mode, external status display, 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 outside temperature sensor installed on the north side
of the building can be used to further optimise the weather-com­pensated feed temperature controller.

If the optional EHS157056 gateway is installed and connected to the
Internet, the Daikin Altherma ETS(X/H) 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 Daikin Altherma ETS(X/H).

Certain menu items of the RoCon+ HP 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 allocated heating circuit can be carried out in the
same way as the operating unit. If the terminal function is activated,
all operating possibilities that are available on the integrated operat­ing unit are available with the exception of certain special functions
(e.g. manual operation).

After appropriate assignment, a connected EHS157068 mixer mod­ule is also operated using the RoCon+ B1 control panel and/or the
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 indoor unit 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" (see Control­ler operating instructions).

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 sys-

tem and hot water storage tank (e.g. draining).

INFORMATION

If there is a danger of frost for only a few days with uncer­tainly in the gas and power supply, the oes not need to be
drained because the heat insulation is very good as long
as the storage tank temperature is observed regularly and
does not fall below + 3°C.

However, this provides no frost protection for the connec­ted heat distribution system.

The energy supply company (EVU) sends signals that are used for controlling the power mains loading and that have an influence on the cost
of the power and availability.

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 control unit must be pro-

tected against the effects of moisture.

▪ To clean the control unit, use a dry cotton cloth. The

use of aggressive cleaning agents and other fluids can
cause damage to devices or lead to an electric shock.

INFORMATION

The Daikin Altherma ETS(X/H) 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 feed target temperatures above
50°C, the efficiency (COP) of the Daikin Altherma ETS(X/
H) can deteriorate (depending on the outside temperature).

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+ HP
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

Chap. 4.5.1).

4.1 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 Daikin Altherma ETS(X/H) is switched to
standby mode. The frost 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 outside temperature sensor is connected and cor-

rectly parametrised in the system configuration
▪ the outside temperature is more than 8°C
▪ there is no heating request
▪ the frost protection function is not active in any connec-

ted HC and
▪ the Daikin Altherma ETS(X/H) has been switched on

for at least 5minutes.

Reduce operating mode

Reduced heating operation (lower room target temperature) accord­ing to the set reduction temperature in the [Reduce room temperat­ure] parameter (see Chap. 4.2).

Domestic hot water preparation according to the feed target temper­atures and switching cycles in the [Hot water auto. 1] hot water time
program (see Chap. 4.2).

Heating operating mode

Heating, cooling mode according to the room target temperature set
in the [Room temperature target 1] parameter (see Chap. 4.2).

A connected outside temperature sensor (weather-compensated
feed temperature control) or a connected room controller also influ­ence the target temperature.

Domestic hot water preparation according to the feed target temper­atures and switching cycles in the [Hot water auto. 1] hot water time
program (see Chap. 4.2).

Summer operating mode

Only domestic hot water preparation according to the set target tem­peratures and switching cycles is carried out in the [Hot water auto.
1] hot water time program (see Chap. 4.2).

All controllers integrated in the RoCon system via the CAN bus are
also switched to the higher-level [Summer] operating mode.

Automatic 1 operating mode (time program)

Automatic heating and setback mode according to the permanent
time programs (see Chap. 4.3):

▪ [Heating circuit auto. 1]
▪ [Hot water auto. 1]

Automatic 2 operating mode (time program)

Automatic heating and setback mode according to the permanent
time programs (see Chap. 4.3):

▪ [Heating circuit auto. 2]

INFORMATION: SWITCHING CONTACT FOR EX­TERNAL OPERATING MODE CHANGEOVER

Switching can also be performed from an external device
(e.g. modem, ...) via a floating switching contact connected
to terminal J8 of the Daikin Altherma ETS(X/H) to the "Ext"
terminals. See Tab. 4-1.

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 con-

tact: Evaluation as a burner blocking contact. If the
switching contact is closed, the external heat generator
has priority.

Tab.4-1 Resistance values for evaluating the EXT signal

INFORMATION

The resistances specified in Tab. 4-1 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 Daikin
Altherma ETS(X/H) (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 Tab. 4-2) are available that are carried out with priority after ac­tivation.

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.

Due to such forced charging, the hot water target temper­ature in the hot water storage tank can exceed 65°C.

This storage tank charging is carried out even when the
[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 Daikin Altherma ETS(X/H) 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 Tab. 4-4 depend­ing on the utility company signal.

Interlink function

Setting the [Interlink function] parameter = On offers the possibility
that the Daikin Altherma ETS(X/H) two different feed temperature
setpoints are included in the controller.

This applies to both weather-compensated control and control ac­cording to a fixed feed target temperature (see Chap. 4.5).

One possible application is, for example, the additional integration of
an HP convector in a surface heating and cooling system.

Prerequisite: 2 switching contacts are connected to Daikin Altherma
ETS(X/H) plug connection J16 (e.g. room thermostats).

▪ [Interlink function] parameter = Off: Deactivated
▪ [Interlink function] parameter = On: Evaluation of the heating and

cooling switching contacts at plug connection J16 on the RoCon
BM2C PCB. Activation of cooling mode only by switching the op­erating mode to [Cooling] (see Chap. 4.1). Setting of the [Room

If the switch-on condition is fulfilled, heat is taken from the storage

tank and this is used to supply the heating system.
Switch-off condition:
Tdhw < T

or Tdhw < [Feed temperature, target] parameter (see

HZUmin

Chap. 4.5.3)

If the switch-off condition is fulfilled, the heating support from the hot
water storage tank is set and the burner takes over the heating oper­ation.

The [Heating support power] parameter limits the maximum power
that can be taken. The [Heating support max. temp.] parameter limits
the maximum temperature that can enter the heating system.

Certain functions and parameters in the controller are restricted by

access rights and are not visible to the user. To gain access to it, the
specialist code must be entered.

4.4.5 Intelligent storage tank management

[→Main menu →Settings →ISM]
If the storage temperatures are high enough, the energy in the stor-

age 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

This function enables uninterrupted heating, even when the evapor­ator is being defrosted. This enables high comfort to be guaranteed,
even with rapidly reacting heating systems (e.g. convectors).

Heating support (HZU)

If the Heating support function ([Heating support (HZU)] parameter =
On) is activated, the energy in the Daikin Altherma ETS(X/H)'s integ­rated storage tank is used to undertake the heating function. If the
storage temperature is sufficiently high, the burner remains inactive.

The minimum value (T

) is calculated as follows: T

HZUmin

HZUmin

= cur­rently active hot water target temperature [Hot water temperature,
target] + [Heating support hysteresis] parameter.

4.5.3 HC configuration

[→Main menu →Configuration →HC config]
This menu is used to adjust the basic functionality of the heating cir-

cuit.
Further explanations and possible settings for the parameters in this

menu can be found in Chap. 7.6.2.

Weather-dependent feed temperature control

If the weather-compensated feed temperature control is active, the
feed temperature ([Feed temperature, target] parameter) is determ­ined automatically according to the set heating/cooling curve de­pending on the outside temperature.

This function is activated in the delivery condition. It can only be de­activated (fixed value control) or reactivated with a technician code.

If the room controller is also connected (EHS157034) to the RoCon+
HP, the target temperatures are controlled according to the weather
and room temperature ([Room influence] parameter).

This function can only be configured using the technician code. Con­tact your heating expert in this regard.

This function is activated or deactivated via the [Weather-com­pensated] parameter in the "Configuration" menu.

▪ [Weather-compensated] parameter = Weather-compensated:

Weather-compensated feed temperature control

▪ [Weather-compensated] parameter = Feed temperature, fixed:

▪ For cooling mode: [Feed temperature, cooling mode] parameter

If the terminal function is activated, the mixer module can be oper­ated and the settings for the assigned heating circuit undertaken via
the RoCon+ B1 control panel of the Daikin Altherma ETS(X/H).

In conjunction with the EHS157034 room control, the mixer module
can also control the assigned heating circuit completely autonom­ously and independently of the heat generator.

Further explanations and possible settings for this menu can be
found in Chap. 7.6.

Frost 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 feed temperature falls below 7°C, the Daikin Altherma
ETS(X/H) heats until the heating feed temperature reaches at least
12°C.

The function is ended if the external temperature rises above the set
[Frost protection temperature] parameter value + 1K and also there
is no other activation condition.

INFORMATION

If low rate functions are activated,
[HT/NT function] parameter = Switch all off
or
[Smart grid] parameter = On
operation of the heat pump can be shut off completely for a

limited period of time by the utility company. In these
cases, regulation is not possible even in frost protection
conditions and the device's internal heating circulation
pump is not switched on.

These situations can be recognised if, in the [→Main
menu →Information →Overview] menu in the operating
data field: "Ext", the "High rate" value or "SG1" is dis­played.

4.5.4 Heating

[→Main menu →Configuration →Heating]
This menu is used to configure heating times and target feed tem-

peratures for heating mode.

INFORMATION

The weather-compensated feed temperature control has
no influence on the feed target temperature in the case of
a hot water circuit request.

With connected Mixer module

The setting of the heating/cooling curves and the activation of the
weather-compensated feed 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 outside temperature sensor con­nected to the Daikin Altherma ETS(X/H) external temperature

sensor is transmitted to the mixer module via the CAN bus.
or as a
▪ Mixer add-on with zone control

A separate outside temperature sensor must be connected to the

mixer module. The assigned HC is controlled according to the out-

side temperature relevant for this zone.

Heating curve

WARNING: FLAMMABLE MATERIAL

In the event of malfunction, the floor heating system, the
screed or the floor structure could be damaged due to
overheating.

▪ Prior to initial commissioning, set the maximum temper-

ature limit in the RoCon+ HP controller ([Max. feed
temperature] parameter) to the maximum permitted
system temperature prior to starting the emission
measurement.

▪ Connect an overheating protection switch (in the build-

ing) at the "Ext" plug connection for external operating
mode switch-over so that the Daikin Altherma ETS(X/
H) is switched to the "Standby" or "Summer" operating
mode. If the [Room thermostat] parameter = Yesor the
[Interlink function] parameter = On, the overheating
protection switch must be connected so that the room
thermostat's switching contact is interrupted.

▪ If the floor 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 feed temperature to the char­acteristics of the building independent of the respective outside tem­perature (weather-compensated feed temperature control, see

Chap. 4.5). Generally speaking, the slope of the heating curve de-

scribes the ratio of the feed 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. The room temperature
measured in the occupied area may differ from the required room
temperature; these deviations can be kept to a minimum by installing
a room thermostat or a room control.

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 outside temperature sensor
and the room controller (EHS157034) are connected (see

Chap. 4.5).

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 6h
If no automatic heating curve adjustment is activated, the heating

curve can be manually adjusted by adjusting the [Heating curve]

parameter).

INFORMATION: MANUALLY ADJUSTING THE HEAT­ING CURVE

Do not make any corrections to the set values for 1 – 2
days, and then only make them in small increments.

▪ Deactivate the external heat sources (e.g. stoves, dir-

ect sunlight, open windows).
▪ Fully open any radiator thermostat valves or actuators.
▪ Activate "Heating" operating mode. Approximate setting

values:

Heating element: 1.4 to 1.6.

Floor heating: 0.5 to 0.9.

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 feed temperatures and low required hot water temperatures),
the required feed temperature can be higher than the storage tank
target temperature. In order to avoid short-term loss of comfort in
heating mode 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 Chap. 7.6.

4.5.5 Cooling

CAUTION: DANGER OF CONDENSATION

In the event of malfunction or incorrect parameter settings,
the floor heating, the screed or the floor structure could be
damaged due to condensation.

▪ Prior to initial commissioning and activation of cooling

mode, set the minimum temperature limit to the min­imum permissible system temperature in the RoCon
controller (parameter [Feed temperature lower limit]).

Prerequisites for cooling mode:
▪ Outside temperature > set value of room target temperature
▪ Outside temperature > set value of the [Start cooling outside

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 switching to "Cooling"
only takes place:

Cooling curve

[→Main menu →Configuration →Cooling →Cooling curve]
The cooling curve determines the feed target temperature in cooling

mode depending on the respective outside temperature. (for
weather-compensated feed temperature control, see Chap. 4.5.3).
Warmer outside temperatures result in a colder feed target temperat­ure and vice versa. The cooling curve can be adapted to the condi­tion of the building by four parameters (see Fig. 4-3).

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 →Cooling →Parameters]
This menu combines further parameters to determine target feed

temperatures in cooling mode.
During weather-dependent T-HS control, the user can increase or

decrease the target feed temperature by a maximum of 5K with the
parameter [Cooling setpoint correction]. A temperature reduction is
limited by the [Feed temperature lower limit] parameter.

INFORMATION

If optional frost protection valves are installed in the sys­tem, the [Feed temperature lower limit] parameter must not
be set below 7°C.

4.5.6 Domestic hot water

[→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] 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 target value 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= 5K; Building insulation= Normal

To activate the solar function, it must be set to "On" in the menu
[→Main menu →Configuration →DHW →Solar function] and the
switching contact EXT (J8) 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 Chap. 4.3). 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 [Anti-le­gionella temperature] depending on the [Anti-legionella day] para­meter. Disinfection starts at the specified start time [Anti-legionella
start time] and is active for one hour. An optionally connected circu­lation pump is automatically switched on during this time.

Floor screed dryout

[→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 floor 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 relat­ing to floor heating systems can be found on the manufacturer's In­ternet portal.

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 after 21days
at the earliest and of anhydrite screeds after 7 days at the earliest in
accordance with the specifications of the manufacturer. The first
heating begins with a feed temperature of 25°C that must be main­tained for 3days. Afterwards, the heating is carried out with the max­imum set feed temperature for the HC (limited to max. 55°C), which
must be maintained for a further 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 EN1264 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.

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 floor 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 Fig. 4-6).
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. For this, the RoCon BM2C circuit
boards and the RoCon+ B1 control units of the Daikin Altherma
ETS(X/H) as well as the optional EHS157034 room station and
EHS157068 mixer module are connected with each other via data
bus lines if necessary. 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.

4.8.1 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 as-

signed 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 control 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 Daikin
Altherma ETS(X/H) or the 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 must be allocated 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").

è The local control panel acts as a remote control for the heat

generator with bus ID 2.

To end terminal operation and switch 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 control for a
mixer module, both the standard screen and the menu
structure are changed (see Chap. 9).

and run times of the heat pump and its components. The [Electr. en­ergy total] parameter describes the total electrical power consump­tion 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 out-

put and power consumption 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]
