1. Product Description

The motor drive for angle seat valves (KFR valves) enables the retrofitting of existing and already installed shut-off valves into remotely controllable smart devices, without interrupting the water supply or cutting into the water pipe.

The motor can be controlled in two different ways:

1. The device can be directly paired with Aqua-Scope main sensors (internet-connected sensors) of the AQM, AQS, or AQX series using the Aqua-Scope app and is then controlled by these sensors. No LoRaWAN network is required. Instructions can be found in the section 'Pairing with Aqua-Scope Main Sensors'.
2. The motor can be directly paired with Aqua-Scope control sensors (not internet-connected) of the FLO, DRY, or CLP series without requiring any additional wireless connection to the internet or a LoRaWAN network. Instructions can be found in the section 'Pairing with Aqua-Scope Control Sensors'.

The motor is powered by a 12V power supply and is fully water- and dirt-resistant up to the power supply unit. An optional battery pack is available for off-grid operation.

Various adapter rings and a sophisticated connection system allow the motor to be used with all modern angle seat valves from DN15 to DN32. Thanks to an additional water sensor that can be plugged directly into the device, the motor can also be used for leakage protection without any wireless connection at all.

2. Parts of the Motor

Handwheel (H)	Inner Coupling (K)	Adapter (Ax)	Distance Rings (D1,D2)
Ball Bearing Seat (Ws)	Motor (M)	Main Body (G)	Bracket (N)

3. Installation of the motor

3.1. Mounting the motor on the valve

The motor drive can be used with all commercially available angle seat valves. However, due to the variety of mechanisms, certain adjustments must be made. When installing, the valve should be normally open (installers recommend opening the valve fully and then closing it slightly with approx. 2 clockwise turns).

1. First, loosen the screw in the center of the handwheel using a screwdriver. Some manufacturers do not use the typical green handwheel. The spindle may be hidden under plastic, but will always have a screw on top and a square end. Keep the screw for later use.
2. Now remove the handwheel.
3. Select one of the 4 adapters (A1...A4) for wrench sizes M17, M22, M27, or M30 that fits well onto the bottom of the valve top (hexagonal or rectangular shape). If none of the supplied adapters fits the valve, refer to the “Custom Adapter” section for further guidance.
4. Select the correct ball bearing seat (W1 ... W3) and place it on the spindle. If the spindle is larger than 8x8 mm, which is required for the largest ball bearing seat, this product cannot be used for this valve. If the spindle is smaller than the smallest ball bearing seat of 6x6 mm, the issue can be resolved similarly to the adapter case. See the instructions in the “Custom Adapter” section.
5. Now fix the ball bearing seat with the screw from step 1.
6. Depending on the size of the valve top and spindle, additional spacer rings (D1, D2) may be required on the adapter ring. If the inner coupler (K) cannot be pushed all the way into the main housing (G) without resting on the valve housing, or if the main housing does not reach the already installed adapter ring, a spacer ring (D1 or D2) must be placed between the adapter ring (Ax) and the main housing (G). This is usually the case with rising spindle valves. The spacer rings are 12 or 24 mm in size and can also be combined into a 26 mm ring. The spare handwheel can be used to test the opening and closing of the valve.
7. Now place the housing (G) onto the adapter or spacer ring.
8. Insert the inner coupler into the housing. It must reach over the ball bearings in both the open and closed positions. The housing is transparent for this purpose.
9. The retainer (N) is needed to hold the entire assembly in position if the valve is not installed upright. It is recommended to always use the bracket. The complete device is attached to the pipe using the two included cable ties. The cable ties can be removed at any time. To slide the retainer over the housing, the two tabs on the housing must be slightly pressed together. There are two small notches on the inner ring of the retainer for this purpose.
10. Finally, place the motor head onto the housing. Sometimes the inner coupler must be slightly rotated so that the gear structure of the motor meshes with the inner coupler.

3.2. Valves from Wilhelm Ewe GmbH and Co. KG

The valves from this company have a unique design. You must insert the split ring (E1+E2) into the 24 mm spacer ring (D1) instead of using one of the adapters A1 ... A4. A small additional spacer ring (DE) is placed directly under the ball bearing seat to fix the valve's grease chamber.

3.3. Custom Adapter

If no suitable adapter is available for the valve seat, a custom one must be made. To do this, select an adapter that fits over the valve seat and fill the gap with a two-component resin. This resin is included with the motor. Cut off a piece of the compound with a utility knife and knead it until a uniform color is achieved. Then fill the gaps between the adapter ring and the valve base. After the resin has hardened, the now custom-fit adapter ring can be used.

Note: The resin will adhere firmly to the valve. If this is not desired, lightly oil the valve beforehand. Then the hardened adapter ring can be removed more easily.

Similarly, a ball bearing seat can be adapted for a valve shaft with a square smaller than 6x6 mm. Ensure that the spindle is precisely centered in the ball bearing seat.

3.4. Setting the End Positions of the Motor Drive

Once the motor is mounted and powered, it must determine the correct end positions for the ‘OPEN’ and ‘CLOSE’ positions:

1. Manually turn the valve to the ‘OPEN’ position before the motor is initially installed. According to installer recommendations, the optimal ‘OPEN’ position is about 2 turns towards ‘CLOSE’ after reaching the stop in the ‘OPEN’ direction (counterclockwise).
2. Power the motor.
3. Press the button briefly once. The motor will now move briefly in both directions and determine whether it is in the ‘OPEN’ or, contrary to the recommendation in step 1, in the ‘CLOSE’ position. This information is indicated by the color of the LED on the device.
4. If the motor was initially in the ‘OPEN’ position, the first ‘CLOSE’ command (either via short button press or external control) will move it fully to the ‘CLOSE’ position and then slightly reverse. This function is intended to relieve the valve's rubber seal. If the seal has become brittle from long-term closing or aging, this may lead to valve leakage in the ‘CLOSE’ position. Therefore, this slight reverse function can be disabled.
   • If paired with an internet-enabled Aqua-Scope sensor, use the app in the “Configuration” section.
   • If paired with a non-internet-enabled device or used standalone, the function can be toggled on or off by pressing and holding the button for 6 seconds (6 * buzzer), then releasing.

Once the end positions are recognized, the motor will no longer forcefully drive against the valve's endpoints, but will instead count the required motor turns and approach the endpoints gently.

4. External Cable Water Sensor

An optional wired flood sensor can be connected to the device. There is a plug on the power cable near the motor. Remove the blue rubber plug and insert the sensor. Please push the connector in firmly to ensure a waterproof connection.

If the sensor head detects water, an acoustic signal will sound, the valve will close, and the alarm will be indicated by a flashing red LED. In addition, an alarm message will be sent via LoRa radio. Once the sensor head is free of water, you can clear the alarm by pressing the button for 2 seconds. It is also possible to clear the alarm via radio.

5. Operation on the Device Itself

The device has a single button with a built-in three-color LED. To operate the valve, you can either click the button or press and hold it for a few seconds. The motor helps count the seconds by beeping once per second. The device is designed for outdoor use and must prevent malfunctions caused by water drops on the button. Therefore, please press the button firmly (not too timidly), even for short clicks, so that the touchless button can detect your finger.

5.1. Button Operation

Using the button on the motor head (G), various commands can be sent to the motor:

• 1 short click: Motor turns to the opposite position (Open–Closed)
• Hold button for 2 seconds: An alarm is deactivated
• 2 short clicks: Status report is sent
• Hold button for 3 seconds, followed by one or three short clicks:
  • 1 click: Enable button lock
  • 3 clicks: Disable button lock
• Hold button for 4 seconds, followed by one or two short clicks: Behavior of the external sensor when no more water is detected (when water is detected, the motor closes)
  • 1 click (factory setting): The motor remains closed
  • 2 clicks: The motor opens again immediately
• Hold button for 5 seconds: If a Wi-Fi radio module is plugged in, this module will be reset to factory settings.
• 6 short clicks: Enable or disable relief of the rubber seal in the 'CLOSED' position
  • 2 * Beep + 2 * green LED flashes (factory setting): enabled
  • 3 * Beep + 3 * green LED flashes: disabled
• Hold button for 10 seconds, followed by 5 short clicks: Motor reset. This function is only necessary if the motor needs to switch from one of the three mentioned operating modes (pairing with main sensors, pairing with control sensors, LoRaWAN) to another.
  • 3 * Beep + 3 * red LED flashes: ok

5.2. LED Signals

The device has a two-color LED with the following meanings:

• Green slow flashing: Open
• Red slow flashing: Closed
• Red and Green fast flashing: Motor is moving
• Red flashing: Alarm
• Red triple flashing: Motor is blocked and cannot move the valve
• Yellow flashing: Searching for connection to the radio network

6. Motor Control via Radio

6.1. Pairing with Aqua-Scope Main Sensors

If a motor is operated with an internet-enabled Aqua-Scope sensor (AQS, AQM, AQX), the sensor must first be connected to the internet. The Aqua-Scope app then allows you to add the motor as a sub-device to the main sensor in the "Configuration" section. The motor is then always controlled via this sensor. In case of an alarm, a control signal is sent directly to the motor without using the internet connection.

6.2. Pairing with Aqua-Scope Control Sensors

The device can also be controlled directly by non-internet-enabled Aqua-Scope sensors (FLO, DRY, CLP). These must be paired with the motor. The sensors are put into pairing mode for this purpose. Information on pairing mode can be found in the manuals of the respective products. On the motor, press the button twice quickly. The sensor and motor are now paired, and the sensor can shut off the water by controlling the motor in the event of an alarm.
