digitalSTROM climate terminal block
Editing device propertiesIn the dialogue Editing device properties, the following parameters are available for the digitalSTROM terminal block air conditioning:
"Heating group“
Select whether the heating system should be controlled by a temperature control or by presets.
.
The Temperature control is the standard of the digitalSTROM heating solution. Here, the digitalSTROM air-conditioning terminal block of the actuator is interconnected with a room climate sensor. Hence, the actuator (heating actuator) is either controlled by the room climate sensor or follows a fixed actuating value.
Pease note that the output of the actuator must be set to pulse width modulation.
The temperature is controlled by the digitalSTROM app Heating Control.
If you select the air-conditioning terminal block as heating, you can then control the connected end devices by pressing a button or directly via the presets.
Pease note that the output of the actuator must be set to switched.
"Connected end device
Select the relevant end device: Unknown, floor heating, wall heating, radiator heating.
Please note that this setting is important, when it comes to being able to automatically select the operating mode in the digitalSTROM server app heating control.
"Push button“
For the heating groups heating, cooling and ventilation, you can define the push button as a device push button or as a room push button.
Please note that this option is inactive for the heating group temperature control.
"Output"
The output of the actuator is dependent on the selected heating group:
• switched for the heating group Heating
• pulse width modulation (PWM) for the heating group temperature control
• deactivated (output is switched off) is possible for both heating groups
Editing climate device properties In the dialogue Change climate device properties for the digitalSTROM climate terminal block, the following parameters are available for the particular digitalSTROM meter:
"Actuator type"
Select whether the valve used is open or closed if there is a control signal.
"Normally open (NO)“
The valve is opened without control signal. If the control signal is present, the valve closes.
"Normally closed (NC)“
The valve is closed without control signal. If the control signal is present, the valve opens.
"Pulse Width Modulation Cycle Time (PWM)"
The valves are controlled by a pulse width modulation signal (PWM). The cycle time determines how long this signal is.
Example: With a cycle time of 900 seconds (15 minutes) and a set point of 50%, the valve is closed during 7.5 minutes and then opened during 7.5 minutes.
"Cycle time of the valve protection signal"
Time within which the valve first moves from the closed end position and back again (only if valve protection is activated).
"Set point during emergency operation"
The opening of the valve when the valve does not receive any control signals due to a fault. With this entry you ensure that your rooms reach a pleasant temperature even during emergency operation.
"Advanced settings “
In the advanced settings, the output for the pulse width modulation and the switched output can be set. The values for the minimum and maximum PMW value, the minimum and maximum control value as well as the offset of the output are defined and displayed graphically in the dialogue.

digitalSTROM indoor climate sensor
Display sensor valuesFor the digitalSTROM room climate sensor, you can display the current sensor values under display sensor values. Thus, a direct and real-time data query is possible.
Please note:
With EnOcean room climate sensors, the sensor values are sent at regular intervals and therefore cannot be called up directly.
Editing device propertiesIn the Editing device properties dialogue it is possible to enter the real or current temperature if necessary (Fig. 42). This will only be necessary if the measured temperature does not match the actual temperature. The offset is calculated and applied automatically.
Please note:
The temperature offset can only be entered for supported devices.

Configuration of heating control
The digitalSTROM heating control is a room-based concept so that each single room can be controlled individually.
The configuration of the heating includes the type of heating control, the settings of the heating per room, as well as the creation of time profiles.
The digitalSTROM heating application provides an infrastructure that intelligently controls individual rooms using connected room temperature sensors and actuators (heating control valves). The temperatures are set for different operating modes as desired and selected depending on requirements.
As a first step, the blue digitalSTROM climate terminal blocks and the temperature sensors (e.g. digitalSTROM room climate sensor dS-iSens200) are fitted. Alternatively, selected radio-based EnOcean devices can also be used.
In a second step, the relevant operating mode (floor heating, wall heating or radiator heating) and the heating group (temperature control) is allocated to the connected end devices (e.g. actuator BL-KM200). These settings can be set for the actuator in the Hardware tab under Edit device properties.
In a third step in the Rooms tab, allocate the digitalSTROM climate terminal blocks and temperature sensors in the digitalSTROM-configurator to the relevant rooms.
In a fourth step install the heating control App under the Apps tab in the digitalSTROM configurator.
In the overview tab select the mode for the normal operation: comfort and eco. This is always active, unless the night or room reduction is active or you are on holiday.
Under rooms, the current temperatures, the target temperatures and the current mode for your rooms are displayed. If required, you can switch the room reduction (mode cool) manually for individual rooms on- or off.
Please note that references to faults and configuration errors are displayed under news and events.
In the Heating tab you can define the standard temperatures in Celsius degrees for all rooms and for the five operating modes (Comfort, Eco, Cool, Night and Holiday). If the selected room is in the operating mode use set control value, then select, instead of the temperature, the desired control value (0% to 100 %) for the valve opening.
You can also easily make these settings in the climate control app on your Smartphone under standard temperatures.
You can choose under behaviour when absent, whether the rooms, when the activity leaving home is activated should automatically be shifted into the mode cool, to actively save energy. This option is particularly useful if the rooms are heated with radiators or if the building is poorly insulated. If your home is equipped with floor heating or is very well insulated, this option is not recommended.
You can easily set the time the heating starts via the Climate Control app on your Smartphone.
The temperature of your apartment is lowered during your holiday. If after your holiday, you would still like to come back to a nice warm home, you can decide using the preheat time at the end of the holiday, how long before you return, the heating should switch to normal operation.
The Cooling tab is displayed automatically if the Heating and Cooling setting was selected for the Properties of the Heating System. This option is only available to heating systems that manage the passive cooling, e.g. heat pumps. At the same time, cold water is pumped through the radiator. The settings for the cooling mode in summer can be displayed and configured here.
You can switch between heating and cooling mode either from a building management system via the digitalSTROM-Gateway or from a sensor terminal using the sensor function switchover heating/cooling.
The switchover heating/cooling by parameter shows whether the last switchover was performed by a building management system or sensor terminal. If a sensor terminal was used, the corresponding terminal is listed under sensor switchover heating/cooling. Additionally, the entire heating system can also be switched off via a sensor terminal. At the same time, the terminal used is displayed with the sensor function Heating switched on/off in the parameter Sensor heating on/off. Please note that the heating is switched on if the contact is closed.
In the room settings you can set the minimum temperature for each room. If this temperature is exceeded, the cooling system in this room is switched off automatically. In the room cooling column, the cooling can also be switched off manually.
In the time profiles tab, you can set time profiles for the night and room reduction, which reduce the room temperature automatically and thus actively save energy.
Configure night reduction: This option allows you to reduce the temperature of your whole apartment (Mode Night).
Configure room setback: This option allows you to reduce the temperature of individual rooms. If, for example, you only need a room at the weekend, the temperature of the room can be lowered on week days (Mode cool).
If you have set both time profiles for the night reduction and for the room reduction, the room is always reduced to the lower temperature.
The night and room setbacks can be defined for every day or for the whole week. You can also flexibly adjust these time profiles in the Climate Control app on your Smartphone.
Your time profiles are displayed with wide bars in the graphical interface.
You can find more information on the configuration of the night and room setback in the on-line help.
In the general settings tab you have the following setting options:
Heating control switched on or off: if the control is switched on, the rooms are regulated to the temperature desired for the active mode. If the control is switched off, all heating actuators are deactivated and the heating valves are closed (NC valves) or open (NO valves). In this way you save energy. The room temperature is also logged and can be read via the Climate Control app. Under building type, choose whether it is a single family house or an apartment in an apartment block.
Under Heating system select the heating or heating and cooling options.
In the Room settings the operating mode of the heating for your rooms, the control value for emergency operation and the associated room sensors and terminal blocks/actors are displayed.
You can choose between the following operation modes (double-click on the selected room):
Off – no control active
Radiator
Floor heating
Control value follows a reference room
Use predefined control values
Automatic (Default)
The operating mode is automatically chosen for the connected end device.
More information on the room settings or operating mode of your heating can be found in the online help in the digitalSTROM Server App Heating Control.
