Operating Instructions

User Interface functionality

The unit has no user-accessible buttons to avoid manipulation of the device in public environments. Installers rely on a pen-shaped magnet to perform tasks related to the installation.

Setting up a Gateway

In a web browser, navigate to the gateway IP address

Pairing the Device with a Room Controller or Gateway

Devices will be accompanied with a spreadsheet containing the following information:

• Device EUI

• Join EUI

• Application Key

The Device EUI is unique to the device and allows identification and communication via LoRaWAN.

The Application Key is randomly generated to ensure secure communication.

To pair a device to a MultiTech gateway:

1. In a web browser, navigate to the gateway IP address

2. Login to the gateway

3. LoRaWAN, Key Management, click Add New

4. For each device, enter the following details, and then click OK:
   Dev EUI (available in the spreadsheet)
   App EUI (available in the spreadsheet)
   App Key (available in the spreadsheet)
   Class: A
   Device Profile: LW102-OTA-EU868
   Network Profile: DEFAULT-CLASS-A

5. Click Submit

6. Wait for Save and Apply to go red, and then click it

Mounting Position and OFF

In mounting position, the plunger inside the valve actuator is fully retracted, so that the unit can easily be attached to a circulation valve. In mounting position, the product is OFF, preserving the charge of the internal energy storage device. This makes it the preferred mode for shipping and storing.

How to enter mounting position from normal operation:

• If the unit is attached to a valve, remove it

• Hold the pen magnet to the micr°pelt logo on the product’s cover until a beep sounds

• The unit will fail the reference run and consequently end up in mounting position

 Upon delivery, all new units are in mounting position.

Attaching and Activating a unit

Before attempting to attach a unit to a valve, be sure it is in mounting position (refer to the above section).

Check the target valve for contamination and leakage. If the valve requires it, do cleaning or service. Then, place the aluminum connector of the product against the valve and secure it by using the ring nut.

Should the target valve not be of type M30 x 1.5, an adaptor is required.

Once the unit is securely attached to the valve,

1. Briefly tap the pen magnet on the micr°pelt logo on the product’s cover

2. The radio establishes a link to the gateway upon successful completion, a double-beep sounds

3. The motor performs a reference run upon successful completion, a triple-beep sounds

4. The unit is now active

Activation only works from mounting position. If performed during normal operation, the product will not show any reaction.

Upon activation, the device initially moves to 50%. From there it makes adjustments as appropriate (moves to the instructed valve position, or monitors and controls the temperature).

Reset (from Normal Operation only)

The RESET function allows access to mounting position. It is also useful to restore correct operation should a malfunction occur.

To RESET the device,

1. Hold the pen magnet to the micr°pelt logo on the product’s cover until a beep sounds

2. The internal microcontroller will reset and restart

If the device is mounted on a valve, it will activate

If the device is unmounted, it will go into mounting position and switch OFF

No Reset from Mounting Position

Removal from the Valve

Unscrew the ring nut from the valve and RESET the device. It will move to mounting position and switch OFF.
