Key Requirements

1. Installation in Each Room:

   • Install a Themo thermostat in every room with hydronic floor heating for precise temperature control.

2. Use of Room Sensor:

   • Themo thermostats must use the integrated room sensor to accurately monitor and regulate the room temperature.

   • Ensure the room sensor is not blocked by furniture, curtains, or other objects, as this can affect its performance.

3. Compatibility:

   • Themo thermostats are compatible with 220V systems and can replace existing wall-mounted thermostats of the same voltage.

   • Note: Themo thermostats do not work with 24V systems or battery-powered systems.

Understanding Heating Dynamics

1. The actual electricity consumption in a hydronic system is made by the air-to-water or ground heat pump that feeds hot water into the system.

2. These systems have inherent inertia, meaning there may be a delay before the system detects the need to start consuming electricity and begins heating.

Setting Up Themo for Hydronic Heating

1. To optimize Themo thermostats for hydronic floor heating, you need to adjust the settings in the Themo app:

   1. Open the Themo App.

   2. Navigate to the Device settings > Configure Device.

   3. Select Heating type option

   4. Choose heating system type as Hydronic heating which is specifically designed for hydronic heating systems.

      • This setting increases the heating cycle duration, ensuring the system operates efficiently and avoids short cycling.

      • The heating cycle duration is set to a minimum of 15 minutes and a maximum of 1 hour, depending on the system's requirements.

      • The app will provide more relevant heating history.

If you experience issues or have questions, refer to the user manual or contact Themo support for assistance. 

By following these steps, you can effectively use Themo thermostats to control your hydronic floor heating system, ensuring optimal comfort and energy efficiency.
