 System Description

 Operating Principle

Uponor Motion is a product that flushes domestic tap water (hot and cold) in a residence to prevent water stagnation. The system monitors the tap water temperatures to detect stagnation. If the water temperature stays in the stagnation zone for a set period of time (default 72 hours), a two-way valve will open and start a flush cycle. The flush cycle continues for a set period of time, or until the water temperature reaches the target temperature (whichever occurs first), returning the tap water to a non-stagnant state.

Components

External Flush/Pair Button (Optional)
The external flush/pair push-button can be used to switch the internal Wi-Fi access point on/off or to initiate a comfort flush.

External Alarm (Optional)
An external alarm can be connected to complement the build-in audible alarm with for example a visual one. The alarm needs to be suitable for a low voltage signal (24 V).

• A – Power LED (green)
• B – Alarm LED (red)
• C – Clear alarm button

Uponor Motion detects problems in the system, such as inadequate flush cycles, out of range temperature sensors, incorrect two-way valve operations and drain water backlog.
Faults are temporary problems that do not affect the overall function of the Uponor Motion.
Alarms are problems that require attention to ensure proper function of the Uponor Motion. When such a problem occurs, operation is halted (to prevent damage). The alarm LED starts flashing and an audible alarm notifies the resident that immidiate action is required. The audible alarm can be silenced by briefly pressing the clear alarm button.
Open the Uponor Motion app to check what kind of alarm it is and how to remedy it. Detailed operating data will also be saved in the datalog (internally for download via app and on the microSD card).

Clearing Alarms

Note
Power cycling (off and on again) the Uponor Motion controller does not clear any alarms. Use the Clear alarm button.

Press and hold the Clear alarm button, for about 5 seconds, to clear any active alarms, or to silence an audible alarm (the alarm is still active though, only silenced). Uponor Motion then performs a system check, and turns off the Alarm LED if all active alarms are remedied.
If an alarm is still active though, the Alarm LED stays on (solid or flashing) until remedied and the Clear alarm button is pressed again. The system will stay in this state for about 72 hours, until returning to active alarm again (audible alarm comes on again if the alarm state is still active).

Call the installer to check the sensor and it’s wiring.

“Valve for hot water is not opening” or “Valve for cold water is not opening”
The Alarm LED flashes.
This alarm is active when the hot/cold water valve receives the signal to open, but does not register as open. The cause can be an actuator failure or a position detector failure. Either could be broken, or the wiring is faulty. If this failure appears only once, it is not critical (it could be an interference of signals) but if the problem persists it should be reviewed by an installer. It could be a wiring issue that can be solved directly or a replacement of the actuator is needed.

1. Press the Clear alarm button to turn off the audible alarm.
2. Try to execute a comfort flush to confirm malfunction of the valve.
3. If the alarm persists or comes on during the comfort flush, call the installer to check the valve, actuator and wiring.

“Valve for hot water is not closing” or “Valve for cold water is not closing”
The Alarm LED flashes.
This alarm is active when the hot/cold water valve receives the signal to close, but does not register as closed. The cause can be an actuator failure or a position detector failure. Either could be broken, or the wiring is faulty. If this failure appears only once, it is not critical (it could be an interference of signals) but if the problem persists it should be reviewed by an installer. It could be a wiring issue that can be solved directly or a replacement of the actuator is needed.
Either
The valve is open (water is running). Call the installer to check the valve, actuator and wiring.
Installer only: To stop the water remove the actuator from the valve and close the valve manually with a slotted screwdriver.
Or
The valve is closed (water is not running).

1. Press the clear alarm button to reset Uponor Motion.
2. Try to execute a comfort flush to confirm malfunction of the valve.
3. If the alarm persists or comes on during the comfort flush, call the installer to check the valve, actuator and wiring.

“Conflicting signals from hot water valve” or “Conflicting signals from cold water valve”
The Alarm LED flashes.
This alarm is active when the hot/cold water valve sends conflicting signals. The cause can be an actuator failure or a position detector failure. Either could be broken, or the wiring is faulty. If this failure appears only once, it is not critical (it could be an interference of signals) but if the problem persists it should be reviewed by an installer. It could be a wiring issue that can be solved directly or a replacement of the actuator is needed.
Either
The valve is open (water is running). Call the installer to check the valve, actuator and wiring.
Installer only: To stop the water remove the actuator from the valve and close the valve manually with a slotted screwdriver.
Or
The valve is closed (water is not running).

1. Press the clear alarm button to reset Uponor Motion.
2. Try to execute a comfort flush to confirm malfunction of the valve.
3. If the alarm persists or comes on during the comfort flush, call the installer to check the valve, actuator and wiring.

Power Cut

During a power cut:

• The stagnation timers keep increasing if the temperatures were for cold water above the cold target temperature or for hot water below the hot target temperature when the power cut started.
• The stagnation timers stay on “0” if the temperatures were for cold water below the cold target temperature or for hot water above the hot target temperature when the power cut started.
• Any type of flush can only be performed once the power is back on.
• Data logs won’t be recorded during a power cut.
• All other data like scheduled flushes etc. are recovered after the power comes back on.
• After the power is back on the connection between Uponor Motion app and the unit will be restored automatically.
