Product description
Depending on heater unit, the electronic, digital controller auto-
matically regulates all heating, cooling and hot water functions for
a direct heating circuit, a storage tank charging circuit and, via
mixer modules that can be optionally connected, also further
heating circuits.
It undertakes all safety management for the ROTEX HPSU
monobloc compact. This executes a safety switch-off in the event
of a water shortage or undefined operating states. A corre-
sponding error message shows the operator all the information
for fault causes.
All function settings for the ROTEX HPSU monobloc compact
and the optional RoCon devices that are connected via the data
bus are undertaken with the controls of the integrated RoCon B1
control panel and shown on the plain text display with coloured
back-lighting.
The following additional, optional devices can be connected to
the ROTEX HPSU monobloc compact via the controller data bus:
–
RoCon U1
room station (
15 70 34).
–
RoCon M1
mixer module (
15 70 68).
In addition, the RoCon mb 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 system).
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.).
Several inputs for evaluating external control contacts are also
available (external operating mode switching or heat request,

Utility company (EVU) outputs signals that are used to control power grid ca-
pacity utilisation and influence the electricity price and availability.
With the optional
RKRSCA1
outside temperature sensor
(
14 10 39
) that is installed on the north side of the building,
weather-dependent T-HS control can be further optimised.
If the optional
RoCon G1
gateway (
15 70 56
) is installed and
connected to the Internet, the ROTEX HPSU monobloc compact
can be conveniently monitored and operated by remote control
using a mobile phone (app).
The RoCon mb control unit contains a timer which can be used
to set:
– 2 individual adjustable switching time programs

for room
heating and room cooling
(direct heating circuit),
– 2 individually-adjustable timer programs for hot water gener-
ation,
– 1 individually-adjustable timer program for an optional circu-
lation pump.

Use of the switching time programs for room cooling only in combination with a
connected room thermostat
Initial commissioning of the heating system is described in the in-
stallation instructions for the ROTEX HPSU monobloc compact.
Certain menu items of the RoCon mb control unit are only acces-
sible for the heating expert. This security measure ensures that
no undesirable malfunctions arise during operation of the system
through incorrect settings.
The RoCon U1 room station has the same user interface as the
ROTEX HPSU monobloc compact's integrated RoCon B1 control
panel.
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. Handbetrieb).
After corresponding assignment, a connected RoCon M1 mixer
module is also operated using the RoCon B1 control panel and/or
the RoCon U1 room station.
The RoCon mb controller is part of the ROTEX HPSU
monobloc compact.
It consists of the
RoCon BM1
printed circuit board, to
which the actuators, sensors and further components of the
ROTEX RoCon regulating system are connected, and the
RoCon B1
control panel.
In this instruction manual we explain just the functions and
setting possibilities of the control unit. More detailed information
on the ROTEX HPSU monobloc compact and other device com-
ponents can be found in the other applicable documents.
