+ 4 K and Tdhw > [T-HS Setpoint] + 1 K.
Heating support deactivated when
Tdhw < T
HZUmin
or Tdhw < [T-HS Setpoint].
T
HZUmin
= current active target hot water temperature [T-DHW Setpoint] + set parameter
value [TDiff-DHW CH ].
Tdhw = current hot water storage tank temperature
[T-HS Setpoint] = current active inflow target temperature (see tab. 6-12 and section 3.6.4)

tion.

Equilibrium Temp Setting affects the operation of the potential-f
ree AUX switching contact (toggle switch out-
put A) defined in the parameter [AUX Fct].
Only when parameter [Equilibrium Func.] = On.
Outdoor temperature from which the optional ancillary heating is activated for supporting
t
he room heating. The bivalent temperature is relevant for operation of the optional ancillary
heater based on a backup demand (room heating operation). The temperature of the sen-
sor integrated into the external unit for heat pump (info value TA2) is used.
The info value TA2 displayed can differ from the value in the standard display depending

Quite Mode Mode for low-noise operation with reduced output (see section 3.4.10).
0: Deactivated

AUX Fct Setting assigns the switching conditions to the potential-free AUX contact (toggle switch
o
utput A; see section 3.6.9).
0: Function deactivated
AUX switching contact changes;
1: When storage tank temperature (Tdhw) ≥ value of parameter [T-DHW 1 min].
2: When there is a cooling or heating demand.
3: When there is a hot water demand to the Backup Heater (EKBUxx) or the configured
B
ackup Heater is required for heating support.
4: When there is a malfunction.
5: When sensor value (TVBH) > 60°C.
6: When the outdoor temperature < parameter value [Equilibrium Temp].
→ Hea
t pump continues to operate = parallel bivalence operation.
7: When the outdoor temperature < parameter value [Equilibrium Temp] + there is a heating
o
r hot water demand.
→ Hea
t pump does not continue to operate = alternative bivalence operation.
8: When there is a hot water demand.
9: When outside temperature < parameter value [Equilibrium Temp] + heat demand "Room
h
eating" (not for hot water demand). Heat pump no longer operates in room heating mode
below the value set in parameter [Equilibrium Temp] - only in hot water mode.
Use: An alternative bivalency operation room heating, if the boiler is incorporated hydrauli-
cally in such a way that it heats the depressurised storage tank water in the Daikin
A
ltherma EHS(X/H) directly (connectio
n via solar connections).
10: "Multi-Oil" - if outside temperature < parameter value [Equilibrium Temp] + heat demand
"
Room heating" (not for hot water demand). Heat pump no longer operates in room heating
mode below the value set in parameter [Equilibrium Temp] - only in hot water mode.
Use: An alternative bivalency operation room heating, if the boiler is hydraulically incorpo-
rated in the flow of the heat pump. For this type
of application, the frost protection function
must be deactivated on the Daikin Altherma EHS(X/H) (parameter [T-Frost Protect] = Off).

With a closed cooling RT switching contact
, the inflow target temperature is increased
by the set value (see tab. 6-1, parameter [Interlink fct]). Demand, e.g. from
