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

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 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.

target] (see "7.7.2Values"[444])
If the switch-off condition is met, heating support from the hot water
storage tank is ceased, and the heat pump takes over 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.

4 Function
This function is activated in the delivery condition. It can only be
deactivated (fixed value control) or reactivated with a technician
code.
If the RoConU1 (EHS157034) room station is also connected to the
RoCon+ HP1, 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 [Weathercompensated] parameter in the "Configuration" menu.
▪ [Weather-compensated] parameter = "Weather-compensated":
Weather-compensated leaving water temperature control
according to the settings made in the [Heating] and [Cooling]
menus.
▪ [Weather-compensated] parameter = "Feed temperature, fixed":
Control based on fixed target temperature
▪ For heating operation: [Feed temperature, heating mode]
parameter or [Feed temperature, reducing mode] parameter
▪ For cooling operation: [Feed temperature, cooling mode]
parameter
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
menu → Information → Overview] menu in the operating
data field "Ext" the "High rate" or "SG1" value is displayed.
4.5.4 Heating
[→Main menu →Configuration →Heating]
This menu is used to configure heating times and target leaving
water temperatures for heating operation.
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).
