Basic Functions And Operating Modes; System Information (Info) - Daikin EHSX04P30A Operating Instructions Manual

The operating mode can be affected by additional functions such
as:
– Weather-controlled flow temperature regulation
– Switching time program
– Setting the temperature target value
– Setting at the room station
– EXT signal (external operating mode switching)
– Quite Mode
– Interlink fct
– SMART GRID - Signal
– EVU (reduced cost tariff) - Signal
– 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

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-
On
pending on the heat demand for the defrosting function, heating
of 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)

Keylock Function
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, one after the other. The number
of displayed parameters depends on the connected components.
No settings can be made to these values.
Keylock Function
● Place the rotary switch in the "Info"
Off

● Press the rotary switch briefly.

● Select the desired information level with the rotary switch.
● Confirm the changes with a brief push of the rotary switch.

● Select the individual information with the rotary switch.
More detailed explanations and possible setting values for this rotary switch setting
can be seen in chapter 6.10.
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:
– External temperature < -2 °C, minimum storage
temperature = 30 °C
– External 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 (EKBUxx) is
switched on automatically on in order to heat up the
storage tank water to at least 35 °C.
Standard display is shown (see fig. 3-2).
