Description
Setting assigns the switching conditions for the potential-free AUX switch-
ing contact (toggle switch output A, see
Function deactivated.
AUX switching contact switches;
If storage tank temperature (Tdhw) ≥ value of [Switching threshold TDHW
(AUX)] parameter.
If a cooling request or heating request is present.
If a hot water request to the backup heater (BUxx) is present or the con-
figured backup heater is requested for heating support.
If an error is pending
If the sensor value (TVBH) is > 60 °C.
If the outside temperature is < [Equilibrium Temp] parameter value. (heat
pump continues to operate = parallel equilibrium mode)
If the outside temperature is < [Equilibrium Temp] parameter value + a
heating request or a hot water request is present. (heat pump does not
continue to operate = alternative equilibrium mode)
If a hot water request is present.
If the outside temperature is < [Equilibrium Temp] parameter value + "room
heating" heat request (not for hot water request). Heat pump no longer op-
erates in room heating mode below the value set in the [Equilibrium Temp]
parameter - only in hot water mode.
Application: Alternative room heating bi-valence mode if the boiler is hy-
draulically integrated so that it directly heats the unpressurised storage
tank water of the Daikin Altherma EHS(X/H) (connection via solar connec-
tions).
If the outside temperature is < [Equilibrium Temp] parameter value + "room
heating" heat request (not for hot water request). Heat pump no longer op-
erates in room heating mode below the value set in the [Equilibrium Temp]
parameter - only in hot water mode.
Application: Alternative room heating equilibrium mode if the boiler is hy-
draulically integrated in the heat pump feed. For this application type, the
frost protection function must be deactivated on the Daikin Altherma
EHS(X/H) ([Frost protection temperature] parameter = Off).
If the heat pump is in the "Cooling" operating mode.
AUX switching contact (A) only switches after a delay if the switching con-
dition (see [AUX switching function] parameter) is present for longer than
the set time.
Storage tank temperature (Tdhw) switching threshold for AUX switching
contact (see [AUX switching function] parameter).
