Frequently asked questions

SEDS can be integrated during the construction phase in any new residential building starting from 15-17 flats.

The SEDS system consists of a plug-and-play base that can be connected to different energy sources. Details on how to integrate SEDS into your building plans? Contact us. Together we will work out how SEDS can make a difference for your project.

SEDS is the most profitable solution for residential buildings from 15-17 units and up.

Correct, the property price of a flat with a SEDS unit is higher than that of a similar flat with a conventional heating system.

So why should you choose SEDS?
Because it’s an investment that quickly repays itself. Self-generated energy makes you less dependent on the energy market. Smart control ensures optimal energy efficiency. And the lifespan of SEDS makes it a one-time, sustainable investment.

Subsequently, energy performance is an increasingly decisive factor in the process of purchasing a new home. Therefore, a home with a SEDS unit is also a smart choice for the future.

Yes.

SEDS is a hybrid source-independent heating system. It can be connected to any energy source. Grey and green, now and in the future. That makes SEDS completely future-proof and ready for the rise of renewable energy sources.

You can request this information from SEDS. We will provide you with the necessary documentation, including:

• The substantiation document
• The datasheet of the SEDS unit

1. Press “+” or “–” to view the current room temperature.
2. The sun or snowflake icon indicates whether the system is cooling or heating (LED indication).
3. Via the shower icon, the temperature of the domestic hot water (buffer tank) can be set. By default, this is set to 55 °C.
4. Use the “+” and “–” buttons to adjust the settings.
5. By pressing the airplane icon, vacation mode is activated (LED indication).

The standard setpoints are:

• 24 °C for cooling
• 21 °C for heating

You can adjust this with an offset of –3 to +3 degrees. This offset is relative to the current standard setpoint.

No, night setback does not provide any additional benefit. The energy saved at night is required in the morning to bring the apartment back up to temperature.

Cooling:
The default setting is 24 °C. If you want the space to continue cooling for longer, press the “–” button and set, for example, –3. This means the system will continue cooling until 21 °C.

Heating:
The default setting is 21 °C. If you want the space to become warmer, press the “+” button and set, for example, +3. The system will then continue heating until 24 °C.

Via the shower icon on the thermostat, you can set the temperature of the buffer tank (minimum 40 °C).

A higher temperature provides more comfort, but also results in higher energy consumption. The heat pump has to work harder, at a lower efficiency, and the thermostatic mixing valve will mix in more cold water to maintain a safe water temperature.

An important nuance is that this does not affect the outlet temperature to the sanitary fixtures, but it does allow hot water to be drawn for a longer period, as the tank is charged to a higher level.

2-pipe system:
The system looks at the total demand within the circuit to which your apartment is connected. From 51% demand for cooling or heating (or no demand), the system switches to that mode. In the case of equal demand (50/50), heating is given priority. Demand per building orientation will generally be more evenly distributed.

3-pipe system:
In a 3-pipe system, the switching takes place within the apartment, giving the owner complete freedom to choose between cooling or heating.

Underfloor heating works via a manifold (inside the SEDS unit). The circuits ensure an even distribution of heat or cold throughout the apartment. This results in a very comfortable and energy-efficient solution.

1. Check whether the buffer tank temperature is set high enough (for example, increase it from 50 °C to 55 °C).
2. Check at all taps whether cold, lukewarm, or hot water is coming out.
3. If the problem persists, contact SEDS at +32 14 42 14 26.

Too warm:

1. Lower the thermostat offset by 2 or 3 degrees.
2. Take solar gains into account, as they can strongly influence the temperature.
3. If this does not help, contact service@seds.be.

Too cold:

1. Increase the thermostat offset by 2 or 3 degrees.
2. Check whether all zones on the manifold receive sufficient flow.
3. Check whether the floor feels evenly warm everywhere.

Allow the system at least 24 hours to respond.

If your bedroom is equipped with additional zone control, the room can be individually controlled. This throttles the temperature within the room and therefore results in less heat in winter and less cooling in summer.

The zone control automatically opens (or closes) the underfloor heating or cooling valve based on the desired temperature in that room. Once the set temperature is reached, the valve closes (or opens) again.

Activate vacation mode via the airplane icon on the thermostat (LED indication). The system switches to an energy-efficient mode, and no domestic hot water will be produced until vacation mode is deactivated.

The installation can remain in either cooling or heating mode and maintains a room temperature of approximately 16 °C.
