Special system settings
The Control RoCon HP already has the basic configuration for
the Daikin Altherma EHS(X/H). However, it needs to be adapted
to the optionally connected accessories and the installation envi-
ronment during initial commissioning.
Adaptation is carried out via the setting of parameters in the
rotary switch setting
"Configuration"
.
Navigating with the rotary switch accesses either the next deeper
level or directly to the appropriate parameter.
3.6.1 Access Rights (Technician password)
Certain settings are restricted by Control access rights. In order
to gain access to these setting values (parameters) you need to
enter the expert
"Setup"
code in the level.
The fig. 3-12 shows the fundamental procedure for entering the
access code. The expert code will be advised to the expert
company in a separate letter.

3.6.2 Heat curve
Caution - danger of overheating with
underfloor heating!
In the event of a fault, or in hand mode, damage may
be caused to the screed, the structure of the floor and
the underfloor heating system by overheating.
●
Before initial commissioning of the underfloor
heating system, set the maximum permissible
system temperature Control RoCon HP
(parameter [T vbh1 max]) in the maximum temper-
ature limit in the Control RoCon HP (parameter
[Max T-Flow]).
●
Connect the overheat protection switch (customer)
on the "EXT" plug connection to the external
operating mode switch so that the Daikin Altherma
EHS(X/H) is in operating mode "Standby" or
"Summer" (see section 3.4.2).
In parameter [Room thermostat] = On or parame-
ter [Interlink fct] = On, the overheat protection
switch must be connected so that the switching
contact of the room thermostat is interrupted.
●
If the underfloor heating system is also used for
room cooling, the connection notes from the
previous section are also valid for the connection
of a customer-provided humidity protection switch.
With the heating characteristic curve, the inflow target temper-
ature is adjusted to building conditions in accordance with the rel-
evant external temperature (weather-controlled flow temperature
regulation, see section 3.6.4). Generally speaking, the steepness
of the heating characteristics describes the ratio of the flow tem-
perature change to the external temperature change.
The heating characteristic curve applies within the minimum and
maximum temperature limits that have been set for the corre-
sponding heating circuit. The room temperature measured in the
living area may differ from the desired room temperature; these
deviations can be kept to a minimum by installing a room station
or a room thermostat.
The
Control
is
set in the factory
so that the
heating curve
does
not adjust itself
during operation.
The
automatic heat curve adaptation
can be activated (pa-
rameter [HC Adaption])
if
the
room station
(EHS157034)
is con-
nected
(see chapter 3.6.4).
Starting conditions for the automatic heating curve adjustment:
– Outdoor temperature < 8 °C
– Operating mode is automatic (I or II)
– Duration of setback phase at least 6 hours
If
an automatic heat curve adjustment
is not activated, the heat
curve can be set
manually
by
adjusting
the
parameter [Heat-
Slope]
.
Manually adapting the heating curve
Do not make any corrections to the set values for 1 - 2
days, and then only make them in small increments.
●
Deactivate additional heat sources (e.g. fireplaces,
direct solar radiation, open windows).
●
Fully open any existing radiator thermostat valves
or setting drives.
●
Activate the operating mode "Heating".
Approximate setting values:
– Radiator: 1.4 to 1.6.
– Underfloor heating system: 0.5 to 0.9.
