Permissible air intake temperatures
The DHW heat pump shuts down outside the permissi-
ble air intake temperatures. In some operating pro-
grams, DHW can also be heated outside the permissi-
ble air intake temperatures, through the use of an
immersion heater (accessories). With type T0S-ze, an
external heat generator can be connected.
Permissible air intake temperatures:
■
For DHW heating in recirculation air mode and recir-
culation air mode with air discharge to the outside
(temperature in the installation room):
3 °C to 35 °C.
■
For DHW heating in outdoor air mode (outside tem-
perature):
-5 °C to 35 °C.
