Initial commissioning
If several control units are incorporated in the RoCon system of a
heating installation, additional parameter settings are relevant for
this and can be used to set the individual functions and param-
eters using the appropriate authorisations.
For the EHS157034 room station
– [RoCon U1 assign] parameter:
– The setting = "Living Room" can be used to influence the
heating circuit defined by the set heating circuit ID.
– The setting = "Mix Valve" can be used to carry out all the
settings for the mixer circuit defined by the set heating cir-
cuit ID.
– [Master-RoCon] parameter:
If the heating circuit ID for the direct heating circuit of a Daikin
heat generator is set, the master RoCon function can be acti-
vated via the setting = "On". Thus, the hot water functions of
the Daikin heat generator can be operated in addition to the
heating circuit functions with this room station.
The activation of the master RoCon function is useful for heat-
ing systems that are constructed of a Daikin heat generator
only (without heating circuit extension) and a room station,
and that are to be operated primarily via the room station (see
following information).
For heating systems with heating circuit extensions, it is rec-
ommended not to activate the master RoCon function (setting
= "Off") and to use the terminal function instead.
For all RoCon B1 and EHS157034 control units
– [Terminaladress] parameter:
As soon as a control unit is assigned to a terminal ID (all set-
tings with the exception of "Off"), the control unit can be used
to activate the terminal function.
After carrying out the [Bus - Scan], all the system components
integrated in the RoCon system can be remotely controlled
using a valid device ID (caretaker authorisation).
If the terminal function is to be used in the heating system, the
terminal ID = 0 must be allocated to a control unit.

Operating support during initial
commissioning and during system
extensions
When a Daikin heat generator or a EHS157034 room station is
switched on for the first time, normally the opportunity of setting
the user language is offered first.
Afterwards, the Daikin heat generator is queried "Use Standard
Config?". This query can normally be answered with "Yes".
Only in special applications (e.g. several heat generators in the
RoCon system) should the answer be "No". In this case, the
"Basic Configuration"
parameter level will be offered in order to
set the necessary adaptations (see tab. 6-16).
In the case of the EHS157034 room station, after setting the user
language, the
"Setup Wizard"
installation menu appears.
The parameters required for the definition of the function, the au-
thorisation and the ID of the room station in the RoCon system
are queried and checked for plausibility.
This prevents duplicate device and terminal IDs being set.
Therefore, it is recommended that you use this installation menu
when extending or making changes to the RoCon system of the
heating installation. To do this, a room station already integrated
in the heating installation must first be reset.
1. Enter the technician code (see chap. 3.6.1).
2. Push the Exit button for at least 5 s.
The
"Special Level"
menu is displayed.
3. Use the rotary button to select the
"RoCon B1/U1 Reset"
program.
4. Execute the program by briefly pressing on the rotary button.
The
"Setup Wizard"
installation menu starts.
Device ID
Unique numbering of a heat gen-
erator or mixer module in the RoCon
system.
Up to 16 device numbers can be allo-
cated.
These device numbers are detected
during a [Bus - Scan] and are dis-
played for identification of a remotely
controlled device.
Daikin heat generator
(RoCon BE1)
[BUS ID HS]
Identical to heat generator detection.
The value must not be the same as the
heating circuit ID of a mixer module in the
RoCon system.
EHS157068 mixer module
[HC Assignment]
Identical to the heating circuit ID.
The value must not be the same as the
heat generator ID of the Daikin heat gen-
erator in the RoCon system.
The value must be the same as the setting
of the address switch (fig. 4-2).
Tab. 4-1 Functional IDs in the RoCon system
1)
A maximum of 8 heat generators can be connected in the RoCon system via the CAN data bus. Several heat generators integrated in the heating installation must
be regarded as a special application. If necessary contact a Daikin service technician.

Parameter
Comments
If the master RoCon function is activated, the oper-
ating mode of the heat generator is set via the room
station, and this is shown on the display.
The settings on the room station are transferred to the heat
generator, but not vice versa. The room station has priority.
If the [Summer] operating mode is set on the room station, for
example, and later the [Heating] operating mode is set on the
control unit of the Daikin heat generator, no heating circuit re-
quirement is generated, as the direct heating circuit (which is
assigned to the room station via the heating circuit ID) is still
in the [Summer] operating mode. The change in operating
mode must therefore be carried out at the room station.
