ing contact (toggle switch output A, see

threshold TDHW
(AUX)
If storage tank temperature (Tdhw) ≥ value of [Switching threshold TDHW
(AUX)] parameter.
Heating/cooling
request
If a cooling request or heating request is present.
BUH request
If a hot water request to the backup heater (BUxx) is present or the con-
figured backup heater is requested for heating support.
Error
If an error is pending
TVBH > 60 °C
If the sensor value (TVBH) is > 60 °C.
Outside temperat-
ure
If the outside temperature is < [Equilibrium Temp] parameter value. (heat
pump continues to operate = parallel equilibrium mode)
Outside temp. +
DHW/heating
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)
DHW request
If a hot water request is present.
Outside temperat-
ure + heating
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).
Multi-oil
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).
Cooling mode
If the heat pump is in the "Cooling" operating mode.
AUX delay
time
0-600 s
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.
