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 compon-
ents in the regulating system are connected and the oper-
ating unit RoCon+ B1.
These operating instructions only explain the functions and
possible settings of the controller. More detailed informa-
tion 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 connect-
ible 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 op-
tional RoCon devices that are connected via the data bus are under-
taken 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 sys-
tem).
The potential-free AUX switching contact can be used to carry out
different control functions in conjunction with external devices (re-
quest from an external heat generator, switching to bivalent operat-
ing 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-com-
pensated feed temperature controller.
If the optional EHS157056 gateway is installed and connected to the
Internet, the Daikin Altherma ETS(X/H) can be conveniently mon-
itored and operated by remote control using a mobile phone (app).
Initial commissioning of the heating system is described in the in-
stallation 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 un-
desirable 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 operat-
ing unit are available with the exception of certain special functions
(e.g. manual operation).
After appropriate assignment, a connected EHS157068 mixer mod-
ule is also operated using the RoCon+ B1 control panel and/or the
EHS157034 room station.

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 re-
main switched on if there is a danger of frost.
If the indoor unit is not required for a lengthy period, it can be tem-
porarily decommissioned.
However, we recommend not to disconnect the system from the
power supply but merely to switch it to "Standby mode" (see Control-
ler operating instructions).
The system is then protected from frost. The pumps and valve pro-
tection 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 uncer-
tainly 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 connec-
ted heat distribution system.
