Examples of boiler control with if/then actions

Navigation in the softwareIf-Then Actions

This page describes example configurations in detail.

Requirements

To use if/then actions, you need a smart-me Limited or Professional license.

Basics

The technical data can be found on the pages of the respective products (e.g. maximum switching capacity).

The configuration of the outputs is described on the inputs and outputs page (e.g. activating output 1).

The basics are described under if/then actions (e.g. where to find if-then actions).

Note that if/then actions only work correctly if the connection to the smart-me Cloud is ensured. Event actions are more limited, but are stored and executed locally.

When configuring if/then actions, always check whether the unit displayed is watts or kilowatts.

The smart-me meters are equipped with bistable relays: if switching on is configured, switching off must always be configured as well.

Introduction

Determine the consumption and plan a reserve for consumption fluctuations

To configure good control, it is important to know the power drawn by the consumers. It is also necessary to plan a reserve for every case. For example, if the attic boiler requires 3 kW, the boiler is switched on when less than -3.5 kW is measured on the balance meter and is only switched off again when more than 0 kW is measured. The 0.5 kW difference then serves as a buffer if someone switches on, for example, a computer (60 watts), so that in this case there is not immediately too little energy available.

Delayed switching on or off

In addition, a time span must be factored in before switching on or off. For example, the boiler is only switched off when the value of 0 kW is exceeded for longer than 5 minutes. This ensures that a short-term consumer such as an oven or a kettle does not immediately result in the consumer having to be switched off and on repeatedly. This is all the more important the larger the building is.

Determine how many consumers can be switched on at the same time

You should always check how the fuses have been dimensioned. This must be taken into account when all consumers are running at the same time, e.g. at night. If the fuse is too small, you must configure the if/then actions so that the consumers are not switched on at the same time.

Determine the switch-on and switch-off times of consumers for staggered switching on

When switching on consumers step by step, e.g. several boilers, you must ensure that the delay between the first and the second consumer is long enough for the first consumer to draw full power. For example, if it only takes 20 seconds for the consumers to draw full power, the consumers can be switched on with a delay of one minute. Provided there is enough electricity available.

If there are fixed switch-on and switch-off times, make sure that they are offset by at least 1 minute. For example, switching on between 5:00 and 8:00 and switching off between 8:01 and 4:59

Switching off consumers

When switching off consumers, e.g. several boilers, it is possible to switch everything off at once. For example, with a delay of 5 minutes (delayed switching off). However, it is also possible to switch off the boilers step by step.

Example of step-by-step switching off with a delay:

• The first boiler switches off with a delay of 5 minutes so that, for example, someone can switch on the kettle without this switching off the boiler.

• The second boiler is switched off after 7 minutes of increased grid consumption (i.e. 5 minutes after the first + 2 minutes waiting time)

• The third boiler is then switched off after 9 minutes of increased grid consumption

Grid-optimized vs. self-consumption-optimized

When configuring the switch-on and switch-off thresholds, you must decide whether the system is grid-optimized, i.e. the consumers switch on and off as far as possible whenever electricity is drawn from the grid. Or whether the system should be optimized for self-consumption. This means that as much electricity from the roof as possible should be used.

• Example for a consumer of 2.5 kW with a reserve for consumption fluctuations of 0.5 kW.

  • Grid-optimized: switch the boiler on at -3 kW and off at 0 kW.

  • Self-consumption-optimized: switch the boiler on at -1.5 kW and off at +1.5 kW.

  • Partly-partly: switch the boiler on at -2.5 kW and off at + 0.5 kW.

When configuring, note that the variant with optimized self-consumption is more profitable in winter, but in summer in good weather the consumers are switched on very early and are already full in the afternoon when the sun is shining.

We have had good experience when the consumers switch on when they can be supplied 100% with solar power and the reserve for small fluctuations in the grid share is taken into account. In other words, the "Partly-partly" example above.

Booster button

Setting up a booster button for a consumer is possible, but makes the setup more elaborate and complicated. Also note that only the owner of the smart-me account has the option of activating a booster button.

For this function, we must use a digital output that is not physically connected to a consumer. We then use the button only as a state for the if/then actions.

Reheating with peak and off-peak tariff vs. reheating with a single tariff.

For boilers that are reheated using the if-then actions, the local tariff structure can be taken into account.

If electricity is cheaper at night, it is common to reheat during the night. However, this means that the boiler usually has its maximum temperature at sunrise.

If a single tariff is applied, it is best to stagger the reheating from 12:00 noon. This way, in summer the boiler can be optimally charged in the morning and, if necessary, heated up in the afternoon. In this way, the solar yield for the boiler is better. In the following examples, reheating takes place at night. If this is to take place during the day, simply change the switch-on times in the examples. Make sure that switching off must also be taken into account.

3-stage boiler control

The example below for controlling 3 boilers can also be used for controlling 1 boiler with 3 phases. The configuration is exactly the same.

When configuring if/then actions, always check whether the unit displayed is watts or kilowatts.

Power of boiler EG: 6 kW

Configuration: Boiler 1 On (EG)

If/then action: Boiler EG On

This if/then action performs the function:

• to switch the boiler on when the balance meter supplies sufficient electricity for more than one minute.

Or

• It is a defined time and the boiler is heated for three hours in any case.

The configuration is explained below in the tabular view. It is important to note that it is an AND action, the threshold is now above and no longer below, and the times are the opposite of switching on (reheating), offset by 1 minute.

To ensure that the boilers are not switched on at the same time, we will build in a delay before each boiler is switched on. The boiler with the shortest delay time has the greatest advantage in using solar energy, as it is switched on first. In this example, we will switch on the boiler with the highest consumption first, so that it has the opportunity to be switched on first after a long period of high consumption, e.g. at midday.
