23�1 Setting up the Smart Home or Smart Energy Control Logic
The Smart Home function is managed according to pre-defined profiles. The following profile options are
available:
•
Surplus management
This profile is defined based on two thresholds. The threshold is defined with an upper threshold for
activation and a lower threshold for deactivation .
•
Deep freezer - with a temperature sensor
A switchable socket with a temperature sensor (option with the Gude connection) is required to use
this profile. The threshold is defined with an upper threshold for activation and a lower threshold for
deactivation . A temperature limit is defined as an additional parameter. When the defined temper-
ature limit is reached, the Solar-Log™ switches the deep freezer on for a period of time according to
the settings.
•
Deep freezer - without a temperature sensor
This profile is defined based on two thresholds. The threshold is defined with an upper threshold for
activation and a lower threshold for deactivation .
In addition to the thresholds, two safeguard periods to switch on the appliance can be defined.
•
Heat pump with a grid company blocking signal
Heat pumps can have a control input for a grid company blocking signal. This input is used by grid op-
erators via ripple control receivers to switch on heat pumps at a certain time. If a heat pump can now
be run with PV power, this input can be used to switch on the heat pumps in relation to the amount of
power being produced. The relay is then turned off during periods with a PV surplus--when the heat
pumps "may" run. When no PV surplus is available, the heat pumps remain deactivated. There are
three configurable periods available to avoid a cool down during periods with a longer deactivation,
e.g. during periods of bad weather. During such periods, the heat pumps are enabled and - if required -
power is purchased from the grid.
This profile is defined based on two thresholds and three periods of continuous operation. The periods
of continuous operation are defined based on the:
•
Time from/to and
•
Month from/to
.

Vaillant heat pump with a grid company blocking signal
This profile is especially pre-configured for Vaillant heat pumps. The function and configuration
corresponds to the "heat pump with a grid company blocking signal" profile.
