Function

4 Function
The system fully automatically controls the operation of the room
heating, room cooling and domestic hot water preparation on the
sanitary side on the basis of the specifications set in the RoCon+ HP
controller. The functions that can influence system operation are de-
scribed below.
Some of the functions and parameters described are restricted by
access rights and can only be set by a heating specialist (see
Chap. 4.5.1).
4.1

Mode

[→ Main menu → Operating mode]
This menu is used to select the operating mode for operating the
device. The current operating mode is indicated by a corresponding
symbol on the start screen.
Standby operating mode (Standby)
NOTICE
A heating system that is not protected against frost can
freeze in the event of frost and thus be damaged.
▪ Drain the heating system on the water side if there is a
danger of frost.
▪ If the heating system is not drained, the power supply
must be ensured and the mains switch must remain
switched on if there is a risk of frost.
In this operating mode, the Daikin Altherma ETS(X/H) is switched to
standby mode. The frost protection function remains unchanged. In
order to maintain this function, the system must not be disconnected
from the mains.
All controllers integrated in the RoCon system via the CAN bus are
primarily also switched to the "Standby" operating mode.
INFORMATION
In the [Standby] operating mode, the heat pump and the
optionally connected backup heater are disconnected from
the power supply (energy-saving mode) if the following
conditions are met:
▪ the outside temperature sensor is connected and cor-
rectly parametrised in the system configuration
▪ the outside temperature is more than 8 °C
▪ there is no heating request
▪ the frost protection function is not active in any connec-
ted HC and
▪ the Daikin Altherma ETS(X/H) has been switched on
for at least 5 minutes.
Reduce operating mode
Reduced heating operation (lower room target temperature) accord-
ing to the set reduction temperature in the [Reduce room temperat-
ure] parameter (see Chap. 4.2).
Domestic hot water preparation according to the feed target temper-
atures and switching cycles in the [Hot water auto. 1] hot water time
program (see Chap. 4.2).
Heating operating mode
Heating, cooling mode according to the room target temperature set
in the [Room temperature target 1] parameter (see
A connected outside temperature sensor (weather-compensated
feed temperature control) or a connected room controller also influ-
ence the target temperature.

INFORMATION: SWITCHING CONTACT FOR EX-
TERNAL OPERATING MODE CHANGEOVER
Switching can also be performed from an external device
(e.g. modem, ...) via a floating switching contact connected
to terminal J8 of the Daikin Altherma ETS(X/H) to the "Ext"
terminals. See Tab. 4-1.
In this case, the switching contact functionality is depend-
ent on the parameter [Func. burner blocking contact]:
▪ [Func. burner blocking contact] = Resistance values
(default setting): Evaluation of the resistance values.
▪ [Func. burner blocking contact] = Burner blocking con-
tact: Evaluation as a burner blocking contact. If the
switching contact is closed, the external heat generator
has priority.

The resistances specified in Tab. 4-1
5%. Resistances outside this tolerance field are interpreted
as an open input. The heat generator switches back to the
previously active operating mode.
The input is not considered for resistance values greater
than the value for "Automatic 2".
If several switching contacts are connected to the Daikin
Altherma ETS(X/H) (e.g. smart grid, room thermostat), the
associated functions may have a higher priority than the
external mode switching. The operating mode requested
by the EXT switching contact is then possibly not activated
or is only activated later.
