If several control units are incorporated in the RoCon system of a
heating installation, additional parameter settings are relevant for
this, which can be used for setting the individual functions and pa-
rameters using the appropriate authorisations.
On the room station EHS157034
– Parameter [RoCon U1 assign]:
– The setting = "Living Room" can be used to influence the
heating circuit defined by the set heating circuit ID.
– The setting = "Mixing Valve" can be used to carry out all
the settings for the mixer circuit defined by the set heating
circuit ID.
– Parameter [Master-RoCon]:
If the heating circuit is set for the direct heating circuit of a
Daikin Altherma EHS(X/H), the setting = "On" can be used to
activate the Master-RoCon function. In addition to the heating
circuit functions, the hot water functions of the Daikin
Altherma EHS(X/H) can also be operated with this room sta-
tion.
The activation of the Master-RoCon function can also be used
for heating installations just made up of a Daikin
Altherma EHS(X/H) (without heating circuit extension) and a
room station, and which are to be operated primarily via the
room station (see following information).
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 in the dispay.
The settings on the room station are transferred to
the heat generator, but not vice versa. The room
station has priority.
For example, if the operating mode [Summer] is set,
and subsequently, on the control unit of the Daikin
Altherma EHS(X/H) the operating mode [Heating] is
set, a heating circuit demand is not generated, be-
cause the direct heating circuit, that is allocated to
the room station by the heating circuit ID, is still in
the operating mode [Summer]. The change in oper-
ating mode must therefore be undertaken at the
room station.
On heating installations with heating circuit extensions, we
recommend not activating the Master-RoCon function
(Setting = "Off") and instead using the terminal function.
With all control units RoCon B1 B1 and EHS157034
– Parameter [Terminaladress]:
As soon as a control unit is allocated a terminal ID (all settings
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
incorporated in the RoCon system can be remotely controlled
using a valid device ID (caretaker authorisation).
If you intend to use the terminal function in the heating sys-
tem, you need to allocate the terminal ID = 0 to a control unit.
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 remote
controlled device.
Daikin Altherma EHS(X/H)
(RoCon BM1)
[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.
Mixer module EHS157068
[HC Assignment]
Identical to heating circuit ID.
The value must not be the same as the
heat generator ID of a Daikin
Altherma EHS(X/H) 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 incorporated in the heating installation must
be regarded as a special application. If necessary contact Daikin service technician.
