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.
If wiring the actuators, we recommend the Loxone Tree cable.
Strip the cable as far as needed and use the thin orange/white wire pair to connect the power supply.
For strain relief, form a small loop between the individual actuators and attach the cable near the first actuator.
The wires are pressed into the terminals of the actuators using the terminal cover, or the IDC Tool (100226) supplied with the Miniserver or Tree Extension.

Make sure that no water can drip onto the actuator. Although the actuator can be mounted in any position, it is recommended to install the actuator above the valve to prevent water dripping onto the actuator in case of a leaking valve or condensation. |
|
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.
The available functions differ depending on whether the device is battery operated or connected to an external power supply. This is determined during pairing. The device must therefore be paired in the same supply method in which it is to be operated later.
If the supply method is changed later, the device must be deleted from the configuration and paired 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.

Safety Instructions↑
When connecting to an external power supply, the installation must be carried out by a qualified technician in accordance with all applicable regulations.
Ensure that the device is protected from water.
The device must not be used as part of safety-critical systems.
