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:
Ex
ternal temperature < -2 °C, minimum storage
temperature = 30 °C
Ex
ternal 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.
In order
to accelerate the heating process with
the back-up heater, temporarily
Parameter [Function Heating Rod] = "1" and
Set parameter [Power DHW
] to the maximum
value of the backup heater.
Set rotary switch to the operating mode and
parameter [1x Hot Water] to "On". Following
su
ccessful heating, reset the parameters to
"Off".
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 condition 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. De-
pending on the heat demand for the defrosting function, heating
o
f the direct heating circuit may be interrupted temporarily.
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 operating sta-
tuses of all system components, on
e 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).
Pr
ess the rotary switch briefly.
The parameter overview is displayed.
Se
lect the desired information level with the rotary switch.
Confirm the changes with a brief push of the rotary switch.
The value is displayed (for example, see fig. 3-6).
Select th
e individual information with the rotary switch.
More detailed explanations and possible setting values for this rotary switch setting
can be seen in chapter 5.10.
Display operating data
The current operating data for the Daikin Altherma EHS(X/H) are
shown on the RoCon HP Control in the "Overview" information
level.
The display of the operating data is not divided into several
wind
ows. By adjusting the rotary switch it is toggled between the
windows.
