3.1 General
DANGER!
If electrical components come into
contact
with
water
,
this can cause an
electric shock
as well as cause
potentially fatal injuries and burns.
●
The
displays and
the
buttons
on the Control
must be protected from the
effects of
moisture
.
●
To
clean
the Control use a
dry cotton cloth
.
Using aggressive
cleaning agents
and other
liquids
can cause
damage to equipment or lead
to an electric shock
.
Maximum energy utilisation
The most effective energy utilisation is achieved by the
HPSU compact at the lowest possible return flow and
hot water temperatures.
At temperatures in excess of 50 °C, the effectiveness
(COP) of the HPSU compact will be made worse by
the heatingsupport provided by the optional heater
(backup heater), depending on the outdoor temper-
ature.
The Control RoCon HP is part of the ROTEX HPSU
compact.
It consists of the control panel PCB, the actors and
sensors and other components of the ROTEX regu-
lating system RoCon connected and the control unit
RoCon B1
.
In this instruction manual we explain just the functions
and setting possibilities of the Control. More information
on the ROTEX HPSU compact and other equipment
components can be found in the supplementary docu-
ments.
The electronic, digital Control 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
ROTEX HPSU compact. This executes a safety switch-off in the
event of a water shortage or undefined operating states. A corre-
sponding fault message shows the operator all the information for
causes of faults.
All function settings for the ROTEX HPSU compact and the op-
tional RoCon equipment connected via the data bus are carried
out with the operating elements of the integrated operating part
RoCon B1 and displayed in clear text display on a coloured
backlit display.
The regulation data bus can be used to connect the ROTEX
HPSU compact to the following optional equipment:
– Room station
RoCon U1
(
15 70 34
).
– Mixer module
RoCon M1
(
15 70 68
).
In addition, the control unit RoCon HP has a frost protection
function for the direct heating circuit and the storage tank
charging circuit, as well as the facility for incorporation of an
additional heat source (wood-burning boiler, solar system) via a
potential-free burner blocking contact or the potential-free AUX
contact.
The weather-controlled flow temperature regulation is more ac-
curate with the optional external temperature probe
RoCon OT1
(
15 60 70
), which can be installed to the north of the building.
If the optional gateway
RoCon G1
(
15 70 56
) is installed and
connected to the Internet, the ROTEX HPSU compact can be
conveniently monitored and operated by remote control using a
mobile phone (app).
The Control RoCon HP contains a timer which can be used to
set:
– 2 individually-adjustable timer programmes for room heating
(direct heating circuit),
– 2 individually-adjustable timer programmes for hot water gen-
eration,
– 1 individually-adjustable timer programme for an optional cir-
culation pump.
Initial commissioning of the heating system is described in the
installation manual of the ROTEX HPSU compact.
Certain menu items in the Control RoCon HP are only accessible
to the specialist heating technician. This security measure en-
sures that no undesirable malfunctions arise during operation of
the system through incorrect settings.
The room station RoCon U1 has the same operating panel as the
RoCon B1 operating element integrated in the ROTEX HPSU
compact.
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).
A connected mixer module RoCon M1 will also be operated, after
appropriate allocation, by the control unit RoCon B1 and/or the
room station RoCon U1.
