Sensors

[→ Main menu → Configuration → Sensors]
Optional sensors are activated and configured in this menu. Pres-
sure setpoints for the water side can be defined.
Further explanations and possible settings for the parameters in this
menu can be found in Chap. 7.6.1.
4.5.3

HC configuration

[→ Main menu → Configuration → HC config]
This menu is used to adjust the basic functionality of the heating cir-
cuit.
Further explanations and possible settings for the parameters in this
menu can be found in Chap. 7.6.2.
Weather-dependent feed temperature control
If the weather-dependent feed temperature control is active, the feed
temperature ( [Feed temperature setpoint] parameter) is determined
automatically depending on the external temperature according to
the set heating/cooling curve.
This function is activated in delivery condition. It can only be deactiv-
ated (fixed value control) or reactivated with a technician code.
If the room controller is also connected (EHS157034) to the RoCon+
HP, the temperature setpoints are controlled according to the
weather and room temperature ([Room Influence] parameter).
This function can only be configured using the technician code. Con-
tact your heating expert in this regard.
This function is activated or deactivated via the [Weather-dependent]
parameter in the "Configuration" menu.
▪ [Weather-dependent] parameter = Weather-compensated:
Weather-compensated feed temperature control
▪ [Weather-dependent] parameter = Feed temperature, fixed: Con-
trol based on fixed target temperature
▪ For heating mode: [Feed temperature heating mode] parameter
or [Feed temperature reducing mode] parameter
▪ For cooling mode: [Feed temperature cooling mode] parameter
INFORMATION
The weather-compensated feed temperature control has
no influence on the feed target temperature in the case of
a hot water circuit request.
With connected Mixer module
The setting of the heating/cooling curves and the activation of the
weather-compensated feed temperature control for the assigned HC
are carried out in the same way as described above.
The assigned HC can be operated as a:
Operating Instructions
18
▪ Mixer add-on
The outside temperature of the outside temperature sensor con-
nected to the Daikin Altherma EHS(X/H) external temperature
sensor is transmitted to the mixer module via the CAN bus.
or as a
▪ Mixer add-on with zone control
A separate outside temperature sensor must be connected to the
mixer module. The assigned HC is controlled according to the out-
side temperature relevant for this zone.
If the terminal function is activated, the mixer module can be oper-
ated and the settings for the assigned heating circuit undertaken via
the RoCon+ B1 control panel of the Daikin Altherma EHS(X/H).
In conjunction with the EHS157034 room control, the mixer module
can also control the assigned heating circuit completely autonom-
ously and independently of the heat generator.
Further explanations and possible settings for this menu can be
found in Chap. 7.6.
Frost protection function
The integrated heating circulation pump is switched on at an outside
temperature below the [Frost protection temperature] parameter
value in order to prevent the heating system from freezing.
In addition, the feed, storage and connected room temperature
sensors are also constantly monitored. If the temperature measured
by one of these sensors falls below 7 °C (below 5 °C at room tem-
perature), the antifreeze function is also activated.
If the heating feed temperature falls below 7 °C, the Daikin Altherma
EHS(X/H) heats until the heating feed temperature reaches at least
12 °C.
The function is ended if the outside temperature rises above the set
[Frost protection temperature] parameter value + 1 K and also there
is no other activation condition.
INFORMATION
If low rate functions are activated,
[HT/NT function] parameter = Switch all off
or
[Smart grid] parameter = On
operation of the heat pump can be shut off completely for a
limited period of time by the utility company. In these
cases, regulation is not possible even in frost protection
conditions and the device's internal heating circulation
pump is not switched on.
These situations can be recognised if, in the [→ Main
menu → Information → Overview] menu in the operating
data field: "Ext", the "High rate" value or "SG1" is dis-
played.

peratures for heating mode.
