Parameter
Power DHW Heating output of electric auxiliary heater for hot water generation
BUH s1 power Heat capacity of the ancillary electric heater in Stage 1 heating support
see operating instructions of immersion heater BUxx.
BUH s2 power Heat capacity of the ancillary electric heater in Stage 2 heating support
see operating instructions of immersion heater BUxx.
Power BIV Setting limits the output of the heating support.
TDiff-DHW CH Only when parameter [HZU] = On.

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)
T vbh1 max Setting limits the inflow temperature (measured at t
tion.
Equilibrium Temp Setting affects the operation of the potential-free 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
the 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
on parameter [Outside Config].
Quite Mode Mode for low-noise operation with reduced output (see section 3.4.10).
0: Deactivated
1: Activated
2: Operated in whisper mode only at night between 22:00 and 6:00 hours.
AUX Fct Setting assigns the switching conditions to the potential-free AUX contact (toggle switch
output 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
Backup 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].
→ Heat pump continues to operate = parallel bivalence operation.
7: When the outdoor temperature < parameter value [Equilibrium Temp] + there is a heating
or hot water demand.
→ Heat 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
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 incorporated hydrauli-
cally in such a way that it heats the depressurised storage tank water in the Daikin
Altherma EHS(X/H) directly (connection 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).
AUX time AUX switching contact (A) switches with a delay when the switching condition (see param-
eter [AUX Fct]) is pending for longer than the set time.
T-DHW 1 min Switching threshold storage tank temperature (Tdhw) for AUX switching contact (see pa-
rameter [AUX Fct]).
Delta-T CH Set outdoor temperature spread The Daikin Altherma EHS(X/H) heating circulation pump
controls the flow rate in order to achieve the set spread between the inflow target tempera-
ture and the return flow temperature (t
V var Current minimum necessary volume flow in the system (calculated value, not configurable)
T-Flow CH adj Only when parameter [Interlink fct] = On.
With a closed cooling RT switching contact
by the set value (see tab. 6-1, parameter [Interlink fct]). Demand, e.g. from
