– Switching time program
– Setting the temperature target value
– Setting at the room station
– Setting on room thermostat
– Switch status at EXT input (external
operating mode switcho-
ver)
– Switch status at EBA input (external demand request)
– Quite Mode
– Interlink fct
– Switch status at SMART GRID input
(EVU function SMART
GRID)
– Switch ststus at EVU input (EVU function HT/NT (low tariff) or
SM
ART GRID)
– Defrosting function
– Frost protection function
– Screed function
–Air Purge
– Manual Operation
Button block
The operating panel on the RoCon HP can be blocked to prevent
inadvertent actuation (see fig. 3-4).
Unlocking can be carried out in the same way.
The prerequisite for this function is that, in the level "Setup", the
parameter [Keylock Function] is set to "On" (see chapter 6.2.1
tab. 6-1).

3.4 Basic functions and operating modes
If the storage temperature falls below a certain
minimum value, the safety settings of the Daikin
Altherma EHS(X/H) prevent the operation of the heat
pump in the case of low external temperatures:
– Extern
al temperature < -2 °C, minimum storage
temperature = 30 °C
– Extern
al temperature < 12 °C, minimum storage
temperature = 23 °C.
Without backup heater:
The storage tank water must be heated to the minimum
required storage temperature by an external heater.
With backup heater (EKBUxx):
With an outdoor temperature < 12 °C and a storage
tank temperature < 35 °C, the backup heater (BUH) is
switched on automatically on in order to heat up the
storage tank water to at least 35 °C.
● I
n order to accelerate the heating process with
the back-up heater, temporarily
– Parameter [Function Heating ] = "1" and
– Set parameter [Power DHW] to t
he maximum
value of the back-up heater.
– Set rotary switch to the operating mode and
parameter [1x Hot Water] to "On".
Automatic defrosting function
At low outdoor temperatures and corresponding humidity values,
the external heat pump unit may ice up. This icing impairs effi-
cient operation. The system detects this condi
tion automatically
and starts the defrosting function.
During the defrosting function, heat is drawn from the hot water
storage tank and the backup heater is turned on if required. 
Depending on the heat demand for the defrosting function,
hea
ting of the direct heating circuit may be interrupted tempo-
rarily.
After 8 minutes at most, the system returns to normal mode.
3.4.1 System information (Info)
In this rotary switch position, the rotary switch can be used to call
up all the system temperatures, the type of Daikin
Altherma EHS(X/H), various software information and the oper-
ating statuses of all system compon
ents, one after the other. 
The number of displayed parameters depends on the connected
components.
No settings can be made to these values.
● Place the rotary switch in the "Info" position.
 Standard display is shown (see fig. 3-2).
● Press the
rotary switch briefly.
 The parameter overview is displayed.
● Select the desired information level with the rotary switch.
● Con
firm the changes with a brief push of the rotary switch.
 The value is displayed (for example, see fig. 3-6).
● Sele
ct the individual information with the rotary switch.
More detailed explanations and possible setting values for this rotary switch setting
can be seen in tab. 3-5 and in chapter 6.10.
