6.6 Smart Grid
In case the air conditioning system is connected to a third-party device
able to provide Smart Grid requests (e.g. a power meter connected to
the grid), the EKMBPP1 is able to receive this information and use it in
order to execute Smart Grid requests to control the power consumption
of the system. When a Smart Grid request is made, the values of the
operation ON/OFF state, operation mode and setpoint of the unit are
stored in memory, to be restored when the grid requests normal
operation again. There are 4 possible Smart Grid operation mode
requests:
Free running (normal operation)
There is no Smart Grid intervention. The unit operates normally,
respecting any local and scheduled configuration.
Forced off (blocked operation)
There is a Smart Grid request to switch the unit OFF. All units
connected to the adapter are switched OFF.
Recommended on
There is a Smart Grid request to consume power, if possible.
▪ All units connected to the adapter are switched ON.
▪ Room buffering (space heating/cooling) will be applied. The system
will heat up or cool down to the setpoint ±1°C.
Forced on
There is a Smart Grid request to consume power.
▪ All units connected to the adapter are switched ON.
▪ Room buffering (space heating/cooling) will be applied. The room will
heat up or cool down to the setpoint ±2°C.
INFORMATION
Smart Grid requests can be overruled, except for Forced off
operation. When trying to overrule Forced off operation by
requesting operation ON, the EKMBPP1 will immediately
request operation OFF again.
