The HERZ Thermiq system offers flexible communication options, allowing connection through three different versions, depending on the product type:
• Wired
• Wi-Fi
• Zigbee
Each version ensures reliable data exchange between room controllers, actuators, and the central control unit, while maintaining compatibility across the HERZ Thermiq ecosystem.
The HERZ Thermiq Window/Door Sensor is a compact, battery-powered device that detects the open or closed status of windows, doors, or other movable elements. It communicates via the ZigBee 3.0 protocol and immediately sends a signal to the HERZ Thermiq App whenever the magnetic contact changes state.
It can be integrated into smart automation scenarios—for example, to switch thermostats to frost protection mode when a window is opened. With its miniature size, it fits easily onto any window or door frame. The ZigBee internet gateway is required for operation.

• Works with ZigBee 3.0 protocol and HERZ Thermiq App
• Supports smart automation (e.g. thermostat frost mode when window opens)
• Miniature design – fits all types of windows and doors
• LED indicator for device status
• Simple, wireless installation – battery-powered
• Requires HERZ Thermiq ZigBee gateway for operation
• Wired
• Wi-Fi
