Valve Actuator Air

The Loxone Valve Actuator Air is a wireless motorized valve actuator for heating systems. By using common adapter rings, it can be mounted on a wide range of valves, which are typically used for radiant floor heating and radiators.

Mounting

In delivery state, the valve is fully open. The Valve Actuator Air performs a calibration run after pairing, so it must be installed before initial start-up. Before mounting, make sure that the valve pin is movable and not rusted.

Then snap the actuator onto the adapter ring. Do not apply excessive force. Make sure that the actuator is correctly positioned on the valve. Only use valve adapters suitable for the valve.

Then insert the batteries or connect the external 24VDC power supply.

Make sure that no water can drip onto the actuator.
The installation position is arbitrary, but in case of a leaking valve or if condensation occurs, it is advantageous if the actuator is located above the valve.
If a large number of valve actuators share one electrical line with a small wire cross-section, significant voltage drop may occur. In such a case, it is recommended to use a larger wire cross-section for the 24V supply line and to switch to a smaller cross-section just before connecting the actuators.

Commissioning

In delivery state, pairing mode will be active after the power supply has been established. This is indicated by the status LED flashing red/green/orange.

Then follow the pairing procedure

To activate the pairing mode manually, hold down the pairing button for at least 5 seconds immediately after inserting the battery.

After pairing, the calibration run starts. The Valve Actuator determines the valve travel and registers the 0% and 100% positions.

By default, the actuator then moves to the 0% position (valve closed). Programming must be created to open the valve again.


LED states

LED state Description
Alternating red-green-orange (frequency 1Hz) Device is in pairing mode.
3 times green, then LED permanently off Device was successfully paired.
Blinking orange (frequency 1Hz) Air device is offline.
Rapid red-green flashing Identification (if powered with 24V).

Device test and calibration run

The actuator can be fully opened or closed for test purposes.
In addition, the actuator can be recalibrated.

If the actuator is battery powered , it must first be woken up.

Then right-click on the actuator in the Periphery tree and select an option:

Device test on: Fully open actuator/valve
Device test off: Fully close actuator/valve
Recalibrate device: Perform calibration run.


Battery Replacement

To replace the batteries, open the cover on the back of the Valve Air actuator. Remove the two AA batteries. After inserting the new batteries, the device restarts and the status LED flashes green 3 times.

The actuator fully opens and remains in this position for 60 seconds. This makes it easier to mount the actuator on the valve. The actuator then returns to the position set by logic.
