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 heat-
er based on a backup demand (room heating operation). The temperature of the sensor inte-
grated 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].

AUX Fct
Setting assigns the switching conditions to the potential-free AUX contact (toggle switch out-
put A; see chapter 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 heat pump or the configured backup heater is re-
quired 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 [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.

Min Pressure
Defines the minimum water pressure.
Pressure monitor function (only if the pressure sensor is activated, [Pressure Config] = On,
see tab. 5-1): If the measured value falls below the set value, the Daikin Altherma EHS(X/H)
is switched off and an error message is generated.
