ReMan / ReCom MVA008 (EN)

EnOcean Link Table

MVA008 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

Comments:

MVA008 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 A5-20-01 (4BS)

Two options are available to teach-in MVA004 with an external Gateway/Controller:  

 Manually via teach-in message (4BS version 3)

Description INDEX 0 = environment to setpoint offset [K]

The ambient-to-setpoint offset [K] is a function related to the ambient sensor to correct the temperature measured in the device. For structural reasons and due to the near field of the radiator, the temperature measured on the MVA unit is subject to deviations from the actual room temperature. In automatic mode (0x00), the drive uses its integrated flow (valve adapter) sensor to determine the actual room temperature using an approximation function. With the other settings, an absolute value is subtracted from or added to the 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 can be changed permanently via index 1. The setting to values less than 10 minutes increases the energy consumption and should therefore only be used for non-permanent maintenance purposes.

Description INDEX 10 = reference run

A reference run can be carried out via index 10, e.g. to move the valve bodies, reset the zero point or switch off an activated but not installed device.

Description INDEX 11 = Automatic environment-to-setpoint offset, A parameter

The so-called A parameter is used in the internal temperature approximation to calculate the correction of the ambient temperature based on the flow temperature measured at the time of measurement (on the valve adapter). This factor causes a parallel shift of the approximated ambient temperature in the steady state of ambient and flow temperature: T Approximated = T Ambient - ((T Flow - T Ambient) * A-Parameter)

Description INDEX 12 = temperature controller gain P parameter (only with PLC = 1)

The P parameter describes the internal multiplier in the temperature control loop (only with SPS bit = 1) for calculating the valve adjustment % value. With setting 30, a valve opening of 19% is calculated for a temperature failure of 1°C (T ACTUAL = 21 ° C and T TARGET = 22 ° C). An internally determined ambient temperature value is used for the internal calculation of the controller when in automatic offset mode, which is why the corresponding valve opening angles are not calculated using the above method.
