GIRA varmeaktor 6-kanal basic KNX REG 211400

This GIRA heating actuator stands out with its six independent switching outputs, each capable of driving electrothermal valve actuators via PWM or 2-point control, making it a flexible choice for KNX-based room temperature management. Unlike simpler actuators, it supports both 24 V AC and 230 V AC output voltages, selectable per channel, to match different actuator types.

Highlights

• 6-fold switching outputs for electrothermal actuators
• Per-channel selectable output voltage: 24 V AC or 230 V AC
• PWM or 2-point control for precise temperature regulation
• Integrated valve protection, frost protection, and emergency operation
• Compact 4 TE DIN rail mounting

In daily use

The actuator is powered directly from the KNX bus, while the outputs require an external auxiliary voltage. Status feedback for each channel is transmitted via KNX, allowing integration into building management systems. Programming is done with ETS software. The device is designed for installation in distribution boards on a DIN rail, occupying 4 module widths.
