EnOcean Remote Management (ReMan), Remote Commissioning (ReCom)

EnOcean Link Table

MVA005 supports the following number of tech-in relationships:

• Inbound EnOcean Link Table:                 0 Teach-in relationships (not existing)

• Outbound EnOcean Link Table:               3 Tech-in relationships

Comment:

MVA005 uses an outbound link table only, inbound relationships are not supported. Manually erasing the outbound link table is not possible. Manual pairing (teach-in) however overwrites the first entry of the outbound link table, clearing the other two entries.

Outbound Teach-In

Outbound teach-in is supported for EEP A5-20-06 (4BS).

Two options are available to teach-in MVA005 with an external Gateway/Controller: 

• Manual via teach-in message (4BS version 3)

• Remote commissioning

ReMan supported functions

• PING

• LOCK, UNLOCK (Acknowledged)

• SET CODE (Acknowledged)

• QUERY ID, QUERY STATUS

Comments:

MVA005 Default Security Code = 0x53C65E34.

Invalid security codes: 0x00000000; 0xFFFFFFFF

Invalid security code settings will be automatically converted in to the default code 0x53C65E34 to ensure further access through Remote Management.

 ^*1RESET DEVICE DEFAULTS:

Immediately after executing the Reset_To_Defaults command, the device is reset to the manufacturer status and restarted. The internal memory is reset (1x red LED) and the drive is started (2x red LED). The manufacturer default parameters are reloaded (see Table 9.5 "DEFAULT" values). The motor then moves to the mounting position and performs a reference run. When installed, the drive is started in the maintenance interval. Unmounted, the drive remains in the mounting position and shuts off. All entries of the link table and the security code remain unaffected

ReCom internal MVA Parameter

Device description file (DDF, xml) can be found here Overview MVA EnOcean

Description INDEX 0 = Ambient to Target Offset [K]

The ambient to target offset parameter [K] is related to a function to correct the ambient temperature measured in the actuator. Due to its mechanical design and the near field of the radiator, the temperature measured is subject to deviations relative to the actual room temperature. In automatic mode (0x00), the drive uses its integrated flow sensor (valve adapter) to determine the actual room temperature value with its internal approximation function. In all other settings than automatic mode, an absolute value is subtracted from or added to the effective measured temperature. Example setting 0x07 = +3K: The temperature output by the ambient sensor is the effectively measured temperature minus 3°C.

Description INDEX 1 = Radio communication interval [s/min]

The radio interval is only relevant when operating in radio communication failure mode (RCE, or controller disabled) and controls the transmit interval of 4BS standard telegrams according to A5-20-06. In standard operation, the 4BS defined radio interval will always override the parameter internal setting. 

Description INDEX 6 = buzzer

Buzzer is used for versioning in some firmware versions; it has no additional function. It is readable but not writable (section 11).

Description INDEX 11 = Ambient to Target Offset (A) Parameter

The so-called “A” parameter is used within the internal temperature approximation function to calculate ambient temperature corrections based on actual measured flow (valve adapter) temperatures. In steady sensor state, the A factor describes the level of parallel shift of the ambient temperature. Function [T Approximated = T Ambient - ((T Flow - T Ambient) * Offset A Parameter)]. Differences in time constants when radiators are turned on and off are compensated with an overlaying smoothing function to eliminate   temperature peaks. The smoothing function is based 2 internal arrays with 3 consecutive temperature values that are compared in its deviations (<1°C) over a time period of 3 x 10 minutes.     

Description INDEX 12 = Temperature Control Gain „P“ Parameter (only when SPS = 1)

The P parameter describes the gain/multiplier within the temperature control loop (only when SPS = 1) to calculate the valve adjustment % value. The default value of 90 corresponds to a valve opening of 18% when T Ambient the Setpoint temperature difference is 1°C. Note: The Automatic Ambient to Target Offset (Index 0 = 0x00) mode does us the approximated temperature to calculate the valve opening value, which is why the corresponding valve opening angles may be different to the above mentioned calculated value.

Description INDEX 14 = Signal Communication Interval

The signal communication interval can be changed from its default value of 12 hours to carry out Remote commissioning operations with short(er) time intervals.
