Parameter settings
Parameter
Function Heating
Setting as to whether there is an additional heat generator (WEZ) for hot water genera-
Rod
tion and heating support (see chapter 3.6.7).
0: No additional WEZ
1: Optional backup heater
2: Alternative WEZ takes over the hot water generation and heating support
3: Alternative WEZ 1 takes over hot water generation and alternative WEZ 2 takes over
heating support
HZU
Heating support from domestic hot water storage tanks when the minimum temperature
is exceeded (see chapter 3.6.8 and parameter [TDiff-DHW CH Support]).
Off: No heating support
On: Heating support function active
Equilibrium Func.
The bivalence function is relevant for operation of the optional ancillary heater based on
a backup demand (room heating operation).
Off: Operation of the backup heater is always possible.
On: The backup heater is only enabled if the temperature falls below the one set in the
parameter [Equilibrium Temp].
SMART GRID
Evaluation of the SG signal (see chapter 3.4.11).
0: SMART GRID function not active; SG signal not evaluated.
1: Depending on the signal from the energy supply company, the heat pump is turned off
(no frost-protection function - see chapter 3.6.5) or run in high-temperature mode.
Mode SG
Only if parameter [SMART GRID] = 1:
Used for a possible target temperature increase in the case of a SMART GRID start com-
mand.
0: Comfort (5 K increase in target domestic hot water temperature)
1: Standard (2 K increase in inflow target temperature and 5 K increase in target domes-
tic hot water temperature)
2: Eco (5 K increase in inflow target temperature and 7 K increase in target domestic hot
water temperature)
HT/NT Function
Setting which specifies which heat sources are switched off when the standard signal is
received from the energy supply company (EVU) in the case of the customer having an
off-peak tariff network connection.
0: Deactivated (no effect)
1: Refrigerant compressor switched off
2: Refrigerant compressor and reserve heating switched off
3: Everything switched off (no frost protection - see chapter 3.6.5)
HT/NT Contact
Specifies whether the HT/NT input is an NC or NO contact.
0: NO contact (switching contact closed = standard tariff)
1: NC contact (switching contact closed = off-peak tariff)
Room thermostat
Configuration of a room thermostat connected to the port J16 on the Daikin Altherma
EHS(X/H) using potential-free contacts.
–
Off: Deactivated
–
On: (Only when parameter [Interlink fct] = Off)
Evaluation of
on the RoCon BM1 circuit board (only when none of the operating modes "Standby",
"Economy mode", "Summer", "Vacation", "Holiday" or "Screed" is active):
a)
b)
c)
Interlink fct
Configuration for systems operating with 2 different inflow target temperatures
(see chapter 3.6.6).
A possible use for this might be the additional integration of aFWXV(15/20)AVEB in a
surface heating and cooling system.
Requirement: 2 room thermostats need to be connected to plug connection J16 on the
Daikin Altherma EHS(X/H).
–
Off: Deactivated
–
On: Evaluation of
the RoCon BM1 circuit board.
Activation of cooling mode only possible by changing operating mode to "Cooling"
(see chapter 3.4.2).
Setting for the parameter [Room thermostat] no longer evaluated.
