Frequently asked questions about the Smart ThermostatListed below are the questions most frequently asked about the Smart Thermostat. Simply click on a question to be taken straight to the answer.
If a WLAN is not available in the room (e.g. if the building is under construction), it is still possible to install the Smart Thermostat and complete the basic configuration using the step-by-step wizard. The connection to the router/network and the mobile phone can then be configured in a second step, even by the end user (two-step commissioning concept).
The Smart Thermostat offers different opportunities to save energy.
- Green Leaf: This indicator appears red when the room operation is not energy-optimized. Simply touch the indicator to turn it into a Green Leaf. The Smart Thermostat will then resume energy-optimized operation.
- Self-learning control algorithms: The Smart Thermostat saves energy by using two self-learning control algorithms (Optimum Start Control and Adaptive Gain Control).
- Scheduler: End users can choose between three different scheduler setpoints (Comfort, Pre-comfort and Economy) to ensure the Smart Thermostat runs as efficiently as possible.
- Optimum Start Control is a self-learning algorithm that figures out how long it takes to heat up a room in order to switch on the heating system just in time. This results in lower energy consumption and better comfort.
- Adaptive Gain Control is a self-learning PID control algorithm which analyzes the dynamic behavior of the room temperature depending on the heating equipment. For each type of building it optimizes the parameters to achieve better loop control. This reduces energy consumption and improves comfort. As a result, the Smart Thermostat learns the characteristics of a room in less than one day and quickly adapts itself without any human involvement.
The following sensors are built-in:
- Indoor air quality sensor to inform users about the indoor air quality level.
- Humidity sensor for controlling and monitoring purposes.
- Temperature sensor to ensure maximum temperature comfort.
- Presence detector (PIR) and proximity sensors that recognize the presence of people and respond without user operation.
- Light sensor for optimum readability of the display.
The built-in presence detector senses movement in a room up to a distance of approximately 8 meters. Small animals are not detected. By default, the Smart Thermostat switches the operation from "Economy" to "Comfort" when people are detected. This function can be disabled. In addition, if people are detected, the Smart Thermostat turns the display ON and shows the temperature.
Installation and wiring
It is possible to connect up to two remote sensors to the multifunctional input. Depending on the configuration, the Smart Thermostat controls the room based either on the remote temperature (the internal sensor is deactivated) or the average temperature of the remote and internal sensors. However, one Smart Thermostat cannot control several rooms at the same time. In this case, several Smart Thermostats need to be installed, one in each room. Note that the app can operate up to 12 Smart Thermostats.
Most likely it is because the Smart Thermostat detects that someone enters the room when a scheduled "Economy" mode is running. In this case, the Smart Thermostat automatically switches from "Economy" to "Comfort" until the next scheduled mode starts. However, you can turn off auto-switching by disabling the “Enable room presence detection” parameter under “Advanced settings.”
The installer or end user needs to configure the timezone setting (default: GMT) using the startup wizard (under “Advanced settings”). If the Smart Thermostat is connected to a WLAN router, the date and time information will automatically be pushed from the cloud and stored in the Smart Thermostat. If the connection is suddenly unavailable, the local device will keep using the stored local date and time until the information synchronizes with the cloud later.
The installer or end user needs to configure the timezone setting (default: GMT) using the startup wizard (under “Advanced settings”). If the Smart Thermostat is connected to a WLAN router, the date and time information will automatically be pushed from the cloud and stored in the Smart Thermostat. This allows the time scheduler to continue running in the Smart Thermostat. The settings will be synchronized later when a WLAN connection is available again.
When you turn on "Auto" mode, the Smart Thermostat follows your scheduler setting to match your preferences. If you would like to turn off "Auto" mode, you can change to "Manual" mode with one click (and vice versa). In "Manual" mode, you can set your home’s temperature by yourself. Each button is visible on the Smart Thermostat display as well as on the home screen of the app.
If you are the owner of the Smart Thermostat, simply choose "Private WLAN". This will allow you to change the WLAN connection in the "Settings" menu and have a direct access to the "Advanced settings".
If you are a service provider or facility manager, please choose "Administered WLAN" and set a password. In this case, the WLAN connection and "Advanced settings" (e.g. optimization parameters) are password protected and can only be changed by the service provider or facility manager under "Advanced settings".
If you would like to change the email address of your account, you need first to reset the old registered email address from your Smart Thermostat by contacting the cloud support team by contacting the global customer support. Afterwards you can restart the procedure to create a new account and pairing your app with the Smart Thermostat.
Usability and application
If the input of the Smart Thermostat has been configured as "window," and the window contact is open, the Smart Thermostat switches the operating mode to protection (OFF). In that case, you cannot operate the Smart Thermostat. Close the window contact so the Smart Thermostat returns to the home screen.
