Once the unit is securely attached to the valve,
Briefly tap the pen magnet on the micr°pelt logo on the product’s cover
The radio establishes a link to the gateway
→
upon successful completion, a double-beep sounds
The motor performs a reference run
→
upon successful completion, a triple-beep sounds
The unit is now active
Activation only works from mounting position. If performed during normal operation, the product will
not show any reaction.
9.6 Reset (from Normal Operation only)
The MLR003FiEU61-12-1.1 RESET function allows access to mounting position. It is also useful to restore
correct operation should a malfunction occur.
To RESET the device,
Hold the pen magnet to the micr°pelt logo on the product’s cover until a beep sounds
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
9.7 No Reset from Mounting Position
9.8 Removal from the Valve
Unscrew the ring nut from the valve and RESET the device. It will move to mounting position and switch
OFF.
9.9 Temperature Control Loop
To obtain an estimate of the ambient temperature, the device measures the flow temperature every 5
minutes and performs a moving average across the last 30 minutes. It then performs the following
computation:
Having established an estimate of the ambient temperature, the device then compares this estimate to
the ambient temperature requested by the user. If they are the same, or if the ambient temperature is
already moving towards the requested temperature, the device does not move the motor. Otherwise, the
device applies a Proportional Controller Gain algorithm to compute the motor movement:
The default value of P is 3. It can be modified via the downlink packet (Section 7.2).
9.10 Antifreeze
The antifreeze function prevents damage to the pipes. Below 6°C at the integrated valve side
temperature sensor, the valve opens to 95%. The 6°C is an absolute temperature, any user-offset is
ignored.
