The controller considers the winter period from December 21 to June
21, and the summer period the remaining months of the year.
Depending on the current active rate and according to the tariff period,
the icon with the corresponding tariff number is displayed on the screen.
“SMART GRID” Modes
It is possible to activate the SG states of the
e-system
for the external
control of the device. Depending on the value of the digital inputs, we
distinguish four operating states SG:
-
SG1 [0 0] (Normal status):
Both the
e-system
and the heat pump
operate normally according to their configuration.
-
SG2 [0 1] (Reduced tariff):
We are in a reduced tariff period, so we will
take advantage of the lower price of electricity to change heat pump
setpoints and produce more heat and cold.
-SG3 [1 0] (Locked status):
The
e-system
sends a compressor lock signal
to the heat pump, but production surpluses can still be used by
activating or deactivating the non-critical loads configured.
-
SG4 [1 1] (Forced status):
There is overload in the grid. The
e-system
will force the maximum possible consumption in the installation to help
balance the grid.
These external signals can be sent by the electric company itself to try
to keep the distribution network balanced at any time.
5.5. Active outputs in controller
The main display also shows the signals at the active outputs sent by the controller at
the bottom of the screen.
