Note
Another way to adjust set temperature1 is to press the
"Plus" or "Minus" buttons from within the default display
(mixed water volume).
Frost protection
Only frost protection remains active if you
set the set temperature to below 20°C
using the "Minus" button. The display
shows "--°C".
 Set temperature2
Note
For hygiene reasons, do not set a DHW temperature of
less than 61°C.
Set temperature2 is the DHW temperature to which the appliance
regulates if an external signal transmitter is connected and active.
In the "Set temperature1" menu, press
"Menu" once to access the "Set tempera-
ture2" menu. The "External signal trans-
mitter" symbol appears.
You can change the value using the "Plus"
and "Minus" buttons. Setting range: 61
- 65 °C
Operation with external signal transmitter
!
Material losses
See "Permissible voltage range for external signal trans-
mitters" in chapter "Specification/data table".
As standard, these appliances are designed to allow you to allo-
cate a separate, individual set DHW temperature to a connected
external signal transmitter, such as a PV system or an economy
tariff transmitter. This set temperature2 is activated if the termi-
nal connected to the external signal transmitter receives a signal
(see chapter "Electrical connection/ External signal transmitter
connection option"). While activated, set temperature2 replaces
the standard set DHW temperature ("Set temperature1").
 Air intake temperature display
An "A" appears as the air intake temper-
ature symbol.
The current air intake temperature is
displayed.
The air intake temperature is displayed
only while the appliance fan is running. If
it is not possible to establish an air intake
temperature, two dashes are shown.
 Enabling the "Runtime-dependent rapid heat-up" function
Note
In appliances with no electric emergency/booster heater,
this parameter has no function.
Note
Only use the runtime-dependent quick heat-up if instruct-
ed by a Stiebel Eltron representative.
Enabling this function is likely to impact the efficiency of
the product and may lead to unnecessary higher energy
consumption and operational costs.
The appliance offers a runtime-dependent rapid heat-up option.
If the selected set temperature is not reached by the heat pump
after a user defined period, the appliance switches on the electric
emergency/booster heater in parallel to back up the heat pump
(subject to this function being enabled).
Once the set value has been reached, the electric emergency/
booster heater remains inactive until the set time has elapsed
again following a heat demand. This function is disabled at the
factory.
This function is set in two stages. First enable the function and set
the runtime in the second parameter.
The tHE0 setting disables the runt-
ime-dependent rapid heat-up function.
This function is enabled via setting tHE1.
The function is disabled at the factory.
Switch between the tHE0 and tHE1 set-
tings using the "Plus" and "Minus" but-
tons. The tHE1 setting allows the electric
emergency/booster heater to cut in if the
set temperature is not reached after expi-
ry of the runtime selected below.
