In the "heating/cooling" parameter level you must
select the "Mode" level.
In the "Mode" parameter level you will find the "Dif-
ference from heating limit" parameter.
Set the desired value at which the heating opera-
tion of the heat pump should be switched off. The
value 0.0 K means that the heat pump only
switches to summer mode if the room set tempera-
ture (Fig. 19), e.g. 20 °C, is reached at the external
probe. Please note the diagram in Fig. 17 for infor-
mation on which value should be set here.
An example setting:
The "colder/hotter" parameter (room target temper-
ature) of +2 °C means a desired room temperature
of +22 °C.
The "Difference from heating limit" parameter
(summer/winter changeover) of 7.0 K means
heating operation of the heat pump up to an out-
side temperature of +15 °C
(+22 °C room target temperature - 7.0 K "colder/
hotter" = +15 °C).
The heating operation is interrupted when the
desired heating limit is exceeded and after the time
stored for the building time constant has passed.
Only the hot water supply is still active.
