Smart Grid
If you want to run Smart Grid, you must connect the Smart Grid modem to the ventilation unit as shown in the picture. The Smart Grid
signal is connected to the circuit board in Compact P2, which also controls AIR and GEO if these have been connected up.
Smart Grid can be economically advantageous because it regulates the power consumption of the heat pump in line with the price of
electricity as it fluctuates throughout the day. Smart Grid receives an external signal from the power supply company. This deter-
mines in which operating setting the unit is to run.
The connection is established via a terminal block that is located at the top of the unit. The connection to the terminal block is carried
out at the back of the cover plate. You then run the wires through one of the cable glands. Connect the signal directly without resistors
as these are already installed in the wire.
You program Smart Grid in the unit software under ‘General settings’. See the options in the Software Instructions.
Smart Grid has four operating settings:
Connection in 7-pin terminal block
Terminal 4: N (Blue)
Terminal 5: SG-A (Black)
Terminal 6: SG-B (Red)
Operating setting Status Description
1. The heat pump is turned off A: Closed
B: Open
The power supply for the heat pump is disconnected, as many
people are using electricity, which results in the price being
high.
2. Normal operation A: Open
B: Open
The heat pump produces domestic hot water in accordance with
the values that have been selected in the settings.
3. Low electricity price A: Open
B: Closed
During these periods when the price of electricity is low, it is
possible to increase the production of domestic hot water.
4. Overcapacity of electricity A: Closed
B: Closed
There is an overcapacity of electricity, the price of electricity is
low, and you therefore have to produce domestic hot water.
