Actuators for mechanical self-powered CAV controllers Type EN, RN, or VFC, and for flow adjustment dampers Type VFR

• Switching between two volume flow setpoint values, e.g. for daytime and night-time operation
• Supply voltage 24 V AC/DC or 230 V AC
• Control input signal: 1-wire control or 2-wire control (3-point)
• Potentiometer or mechanical stops
• Positive lock connection with CAV controller
• Retrofit possible

• Motorised, variable setpoint adjustment on the CAV terminal unit
• 24 V AC/DC supply voltage
• Control input signal: Voltage signal 2 – 10 V DC
• Specification of setpoint value range by mechanical stops
• Positive lock connection with CAV terminal unit
• With potential-free auxiliary switches for end position monitoring
• Retrofit possible

Actuators for mechanically automatic CAV terminal units EN (Generation 3) and VFC as well as flow adjustment damper VFR

• Motorised, variable setpoint adjustment
• Supply voltage 24 V AC/DC
• Control input signal: Voltage signal 0 – 10 V DC
• Setting the setpoint range by adjusting the potentiometer on the actuator
• Positive lock connection with CAV terminal unit or flow adjustment damper
• Retrofit possible

Actuators and installation accessories for mechanical self-powered CAV controllers Type EN, RN, or VFC, and flow adjustment dampers Type VFR

• Parts kits for easy retrofit
