Control & power
- Control type
- Switched power
- Power supply
- 230 V AC, 50/60 Hz
A suitable thermostat or relay switches the actuator’s 230 V supply. Thermal movement is gradual rather than instantaneous.
A suitable smart controller can expose supported functions to Matter. The control type alone does not confirm electrical compatibility or actual position feedback.
Technical specifications
Selection & installation notes
- Thread size alone does not guarantee valve compatibility; closing dimensions and valve geometry must match.
