Siemens
The Siemens product category includes a range of components for heating, ventilation, and air conditioning systems. These products are designed for integration into professional heating systems and include standalone fan speed switches, three-way sets with motor drives, direct zone valve sets, heat meters, mechanical thermostats, and electronic controllers. They are commonly used in applications such as zone control, flow regulation, and system monitoring in commercial and residential buildings.
These components are suitable for installation in IVAR and other compatible heating systems, and are intended for use by qualified installers and contractors.
How to choose
- Select the correct nominal diameter (DN15, DN20, DN25) based on the pipe size and flow requirements of the system.
- Ensure compatibility with the control system and existing components, such as thermostats and controllers.
- Check the operating principle and actuation type (mechanical or electronic) to match the control strategy of the installation.
- Verify the flow capacity (e.g., 0.6m3/h, 1.5m3/h, 2.5m3/h) to ensure it meets the system's hydraulic requirements.
Frequently asked questions
