IP54 protection in the following mounting positions: Accessory mounting holes Maintenance ● ● The VAV compact controllers are maintenance-free. Disconnect the electrical connections from the terminals if you need to service the device. CAUTION Risk of injury from electric shock There is a risk of injury from electric shock when using the gear train disengagement slider to manually adjust the actuator. ● The actuator must be in a de-energized state during manual adjustments.

Commissioning and parametrization Parametrizing the VAV application The VAV compact controllers are parametrized via configuration tools, see Equipment combinations [▶ 2]. The VAV compact controllers are pre-configured by the OEM via the PPS2 interface (with AST20 or ACS931). Some parameters can be changed during commissioning, operation, or maintenance. Parameter Range Description Factory setting Operating mode CON (VAV operation) / 3P (pos.
Operating modes Operating mode CON / VAV - variable air volume control Variable air volume control (VAV): The operating point is determined by the setpoint (DC 0…10 V or DC 2…10 V signal at YC input) and the Vmin / Vmax settings.
Override control with YC = 0 V for setpoint range 2…10 V When the setpoint signal range (YC) is set to DC 2…10 V, the actuator can be driven to "fully closed" by setting YC = 0 V. The hysteresis behavior is shown in the diagram below. Operating mode CON / VAV YC 2…10 V A full closure by setting YC = 0 V in 2-10 V operation overrides the inputs Y1 and Y2.
Operating mode 3P - open loop control To use VAV compact controllers as 3-position actuators with air volume flow measurement, the parameter "operating mode" must be set to "3P". In this operating mode, air volume flow control by the VAV compact controllers is deactivated and the parameters Vmin, Vmid, and Vmax have no effect. The damper opening direction is determined by the connection of signal inputs Y1 and Y2.
