Zennio ZCL8HT230v2 HeatingBOX 230V 8X v2 KNX lämmitystoimilaite 8 lähtöä AC

The Zennio ZCL8HT230v2 HeatingBOX is a KNX heating actuator designed for precise control of up to 8 independent heating zones. With silent triac outputs and support for both PWM and On/Off control modes, it is ideal for managing electrothermal actuators in residential and commercial buildings. The device mounts on a DIN rail and requires a 230V AC auxiliary power supply for the outputs.

Advantages

Silent switching triac outputs eliminate noise, making it suitable for quiet environments. The integrated valve protection function periodically activates valves to prevent seizing. Manual control via push buttons and LED indicators provide easy local operation and status monitoring.

Suitable for

• Underfloor heating systems
• Radiator heating control
• Multi-zone HVAC management
• KNX building automation projects
