- Fritz Volkert
Product | Feature | Description | FPORT | Keywords | Benefits |
MLR003R | Operating mode setpoint ambient temperature °C w/o external room temperature sensor value °C | Device receives °C setpoint temperature value | 0x01 | Room temperature control accuracy Adjustable PI control | Operates on its optimized internal PI-controller with adjustable parameters. No external room sensor required. |
MLR003R | Operating mode setpoint ambient temperature °C with external room temperature sensor value °C | Device receives °C setpoint temperature value plus room sensor value | 0x01 | Room temperature control accuracy Adjustable PI control Motor travel | Operates on its optimized internal PI-controller with adjustable parameters and reduced motor travel. |
MLR003R | External Temperature Sensor expiry | Decide for how long the MLR003 is using its last received external room sensor value.
| 0x09 | External Temperature Sensor expiry | If a Room Temperature is sent by Downlink, continue using it until: a) new Room Temperature is sent by Downlink, or until b) the Device loses Gateway communication, or until c) individual time setting |
MLR003R | PI(D) control closed percent | Adjustable PI parameter Closed Percent (Minimum percent that device will close to) | 0x07 | PI Closed Percent | Eliminate the dead are from 0% to effective water flow (valve opening point), see FPORT 0x05 |
MLR003R | PI(D) control offset percent | Adjustable PI parameter Offset percent (Percentage Offset to be added to PID Output) | 0x07 | PI Offset Percent |
|
MLR003R | Operation with external temperature sensor | Device receives °C setpoint temperature value | 0x0a | External room sensor | Device receives its room sensor value only on Byte 1. Reduced payload size. |
MLR003R | Operating mode valve Position % | Device receives valve position % values from an external temperature controller | 0x01 | Room temperature control accuracy | When external PI room temperature control is used from e.g. existing building automation |
MLR003R | Internal flow sensor measurement | Device receives °C flow temperature value | 0x01 | Internal flow sensor | Useful to analyze flow distribution in buildings. |
MLR003R | Battery measurement | Device returns its battery voltage with standard LoRaWAN MAC command … | 0x00 | Battery status | Battery status |
MLR003R | Energy management and harvesting | Device measures its averaged consumption as well as generation between active periods | 0x01 | Energy management, Harvesting | Energy status |
MLR003R | Adjustable motor travel distance | Mass flow reduction through reduced motor travel distance (resolution increases with reduced mm operating range over 0…100%) | 0x03 | Hydronic balancing | Allows hydronic balancing. Useful in unbalanced radiator and uncontrolled/over dimensioned flow temperature installations. |
MLR003R | Local ambient temperature measurement | Flow raw offset correction | 0x08 | Smart and adjustable local ambient measurement |
