Special system settings
The RoCon mb controller is already basically configured for the
ROTEX HPSU monobloc compact. However, it must still be
adapted to optionally connected accessories and the installation
environment during initial commissioning.
The adjustment is carried out by setting the parameters in the
"Configuration"
rotary switch setting
.
The next lowest level can be accessed or the respective pa-
rameter directly accessed by navigation with the rotary button.
3.6.1 Access rights (technician code)
Certain settings in the control unit are limited by access rights. To
receive access to these parameters, the technician code must be
entered at the
"Setup"
level.
Fig. 3-13 shows the basic procedure for entering the access
code. The expert company receives the technician code in a sep-
arate letter.
3.6.2 Heat slope
The heat slope is used to adjust the target feed temperature to
the characteristics of the building depending on the respective
outside temperature (weather-dependent T-HS control, see
chap. 3.6.4). Generally speaking, the steepness of the heating
slope describes the ratio of the T-HS change to the external tem-
perature change.
The heat slope is valid within the limits of the minimum and
maximum temperatures set for the respective heating circuit. De-
viations may occur between the room temperature measured in
the occupied area and the desired room temperature; these can
be minimised by installing a room station or a room thermostat.
The
control unit
is set at the
factory
in such a way that the
heat
slope
does
not independently adjust itself
during operation.
Automatic heat slope adaptation
can be activated (parameter
[HC Adaption]),
if
the
room station
(RoCon U1,
15 70 34) is
connected
(see chap. 3.6.4).
Start conditions for automatic heat slope adjustment:
– Outside temperature < 8 °C
– Operating mode is automatic (I or II)
– Duration of the setback period is at least 6 h
If
no automatic heat slope adjustment
is activated, the heat
slope can be
manually
adjusted by
adjusting
the
[Heat-Slope]
parameter
).

Caution - Risk of overheating of floor
heating!
In the event of malfunction or during manual
operation, the floor heating, the screed or the
floor structure could be damaged due to over-
heating.
●
Prior to initial commissioning of the floor
heating system, set the maximum temper-
ature limit in the RoCon mb controller
(parameter [T vbh1 max]) and the maximum
permissible system temperature (parameter
[Max T-Flow]).
●
Connect an overheating protection switch (in
the building) at the "EXT" plug connection to
external operating mode switch-over so that
the ROTEX HPSU monobloc compact is
switched to "Standby" or "Summer" operating
mode (see chap. 3.4.2).
With parameter [Room thermostat] = On or
parameter [Interlink fct] = On, the overheating
protection switch must be connected so that
the room thermostat's switching contact is
interrupted.
●
If the floor heating is also used for room
cooling, the connection notes in the above
point also apply to the connection of a
moisture protection switch in the building.
