Product description
The Controller RoCon HP is part of the Daikin
Altherma EHS(X/H).
It consists of the
RoCon BM1
control panel to which
the actuators and sensors, as well as other compo-
nents in the Daikin RoCon regulating system, are con-
nected, and the
RoCon B1
operating unit.
In this instruction manual we explain just the functions
and setting possibilities of the Controller. More infor-
mation on the Daikin Altherma EHS(X/H) and other
equipment components can be found in the supple-
mentary documents.
The electronic, digital Controller is able to automatically control all
heating, cooling and hot water functions for a direct heating
circuit, a storage tank charging circuit and optionally connectable
mixer module, depending on the heating unit in question.
It is responsible for all safety management functions of the
Daikin Altherma EHS(X/H). This executes a safety switch-off in
the event of a water shortage or undefined operating states.
A corresponding fault message shows the operator all the infor-
mation for fault causes.
All function settings for the Daikin Altherma EHS(X/H) and the
optional RoCon devices connected via the data bus are carried
out with the operating elements of the integrated RoCon B1
control panel and displayed in clear text display on a coloured
backlit display.
The regulation data bus can be used to connect the Daikin
Altherma EHS(X/H) to the following optional equipment:
–
EHS157034 room station
–
EHS157068 mixer module
.
In addition, the RoCon HP control unit 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 (inclusion of an additional source of heat such as a wood-
burning boiler or solar installation).
The potential-free AUX switching contact can be used to carry out
different control functions in conjunction with external devices
(demand 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
demand, SMART GRID- and low-tariff EVU functions

Energy supply company (EVU) sends signals that are used for controlling the
power mains loading, and which have an influence on the cost of the power and
availability.
The weather-controlled flow temperature regulation can be opti-
mised with the
RoCon OT1
optional external temperature probe
which can be installed on the north face of the building.
If the
EHS157056
optional gateway is installed and connected to
the Internet, the Daikin Altherma EHS(X/H) can be conveniently
monitored and operated by remote control using a mobile phone
(app).
The Controller RoCon HP contains a timer which can be used to
set:
– 2 individually-adjustable timer programmes

for room heat-
ing and room cooling
(direct heating circuit),
– 2 individually-adjustable timer programmes for hot water gen-
eration,
– 1 individually-adjustable timer programme for an optional cir-
culation pump.

Use of the timer programme for room cooling only possible in combination with
a connected room thermostat
Initial commissioning of the heating system is described in the in-
stallation manual for the Daikin Altherma EHS(X/H).
Certain menu items in the Controller RoCon HP are only acces-
sible to the specialist heating technician. This security measure
ensures that no undesirable malfunctions arise during operation
of the system through incorrect settings.
The EHS157034 room station has the same operating panel as
the Daikin Altherma EHS(X/H) B1 operating element integrated
in the RoCon B1.
All settings for the allocated heating circuit can be carried out in
the same way as the operating unit. With activated terminal
function, all operating possibilities that are available on the inte-
grated operating unit are available, with the exception of certain
special functions (e.g. Manual Operation).
An EHS157068 connected mixer module will also be operated,
after appropriate allocation, by the RoCon B1 control unit and/or
the EHS157034 room station.
