Using the Energy Planner of the Ecosoft Smart Grid Controller

Heat pump efficiency: A value of 3.0 means that 1 kWh of electrical energy is converted to 3 kWh of heat energy. The COP of a heat pump advertised by the manufacturer indicates a theoretical efficiency, which will not be reached most of the time in reality. The efficiency depends on the input and output temperature. Fill in the real efficiency at (SPF), to make a good comparison with gas prices possible. This option is only applicable in a hybrid (gas/electrical) system.

Gas boiler efficiency: Fill in here how efficient the used gas heater is. An efficiency of 100% means that 1 m3 of gas is needed for 9.77 kWh of heat energy. This option is only applicable in a hybrid (gas/electrical) system.

Heat Pump Control:
Heat Pumps can be set to four different states using the SG (Smart-Grid) interface. These states are: Halt, Normal, Boost, Max. How a heat pump operates during one of these states can often be configured in the heat pump itself. In the Energy Planner options that are shown below, you can determine when the Smart-Grid Controller will switch the heat pump in one of these 4 states.
Some heat pumps only have an EVU connection. In that case, only the states Halt and Normal are applicable.

[Halt] when gas heating is less expensive: The operation of the heat pump can be stopped (blocked) when gas heating is less expensive. Comparison will be made based on gas and electricity prices, and the configured efficiency of both heating methods. This option is only applicable in a hybrid (gas/electrical) system.

[Halt] The operation of the heat pump can also be stopped when electricity is more expensive than a certain configured amount per kWh (price inclusive of taxes), or during hours at which electrical energy is most expensive.

[Boost] The heat pump can be set to an elevated state (more power consumption) when electrical power is cheaper than a configured amount per kWh (price inclusive of taxes), or during hours at which electrical energy is cheapest.

[Max] The heat pump can be set to a maximum state (even more power consumption), when electrical power is cheaper than a configured amount per kWh (price inclusive of taxes), or during hours at which electrical energy is cheapest. It is possible that during the Max state, extra electrical heating will be applied having a lower COP than normal. Preference will be given to assign to the cheapest hours to the Max state, instead of the Boost state.

[Normal] If none of the three other states is active, the Normal state will be active. In that case the heat pump will operate in the same way as without a connected Smart Grid Controller.

Current plan
The plan is shown as text: It will shown the states (Halt/Normal/Boost/Max), each of them placed between to times. The time preceding an operation state is its start time. The time following a operation state is its stop time.
The planning is shown by a row of color codes. Every colored block stands for 1 hour of the day.
blue = Halt, grey = Normal, orange = Boost, red = Max.
