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 FloorHub control box enables precise regulation of up to 8 heating zones, including 6 wireless and 2 wired zones. It communicates via ZigBee 3.0 wireless technology, ensuring stable and efficient operation of underfloor or radiator heating systems.
The unit includes a magnetic antenna with a 1 m cable to extend the communication range and supports the binding function for wireless linking with dedicated thermostats. It features outputs for pump and boiler control, including a 3A voltage output for the circulating pump and a voltage-free NO-COM-NC output for heating devices such as gas boilers.
Additional functions include adjustable pump and heat source shutdown delay (0–15 min), built-in 3-minute switchon delay, and removable connectors for simplified wiring. The control box can be mounted on a DIN rail or flat surface and requires an Internet gateway for remote operation and integration within the HERZ Thermiq system.
Product highlights
• Controls up to 8 heating zones (6 wireless, 2 wired)
• ZigBee 3.0 wireless communication for reliable operation
• Magnetic antenna with 1 m cable for extended range
• Pump and boiler control outputs (3A pump / NO-COM-NC boiler)
• Adjustable shutdown delay from 0 to 15 minutes
• Built-in 3-minute start delay for safe system activation
• Removable connectors for easy wiring
• Mounting on DIN rail or flat surface
• Requires HERZ Thermiq Internet gateway for remote control
The control box is adapted to work with NC type actuators (normal closed). The wires of the thermoelectric actuators should be plugged in removable connectors in the appropriate zones. Current load of each zone is adapted to support up to 6 thermoelectric actuators with a power of 2 W. With more actuators in one zone, use additional relay to relieve the output of this zone.
When the actuator has no power, it is closed. After applying 230V voltage, the actuator will open.
