Operating instructions MVA009 ReCom

In order to teach and configure the drive via ReCom, it is mandatory to change the default security code first!

No	Objective	Button No.	Action	LED or Tone activity	Reasons for failure
1	Change security code from mounting position	Turn dial to end position Left OR Right for short press.	The drive is activated and sends a SIGNAL telegram. The room controller changes the default security code of the drive and prepares it for the configuration. The device then carries out a reference run. When mounted, the drive activates and transmits a 4BS telegram every 2 minutes, as well as every 12 hours (default) a SIGNAL telegram. Unmounted: Device goes into the mounting position and shuts off.	NONE	If the drive does not react to ReCom communication, then the change in the security code may have failed.
2	SIGNAL and ReCom from mounting position (Security code has been changed)	Turn to end position Left OR Right for short press.	The unit activates and transmits one single SIGNAL telegram to allow the controller to change desired Linktable and/or parameter. Device executes Reference run to either activate (mounted) or return to mounting position and switch off (unmounted). Each Signal telegram will be followed by standard 4BS telegram.	No tone signals Successful execution of device internal ReCom Parameter: green-red-red	If the drive cannot be configured, the security code may not be changed successfully
1&2	The commands SEC CODE change, write link table, write parameters can also be performed in a single ReCom session (note TCM Maturity Time).
3	Configuration with SIGNAL and ReCom from normal operation (Security code has already been changed)	NONE	The drive sends a SIGNAL telegram every 12h (default interval), giving the room controller the opportunity to configure. Thereafter, the drive continues its normal operation	Successful execution of device internal ReCom Parameter: green-red-red

All further standard installation and use procedures are identical with manual teach-in:

Assembly

Reference run → Normal operation

Setpoint adjustment

Mounting position = Off → Disassemble

Manual reset

Note: If the link table is not correctly described (no teach-in), the unit will remain in self-controlled mode at 21°C and does ignore any room controller. Local inputs / changes to the setpoint temperature on the dial are possible. Local entries lead to the immediate transmission of a data telegram.

Remarks Remote Commissioning

The ReCom specification of the EnOcean Alliance applies

ReMan / ReCom processes are executed in response to the signal sent by the drive (SIG)

SIG telegrams are sent:

o Every time the drive is started from the installation position. Actuators in operation must first be deactivated as follows: Turn against the left or right stop, hold for 5 seconds until 1x green LED, turn briefly against the opposite stop and release immediately, 3x red LED

o For drives in operation: Deactivate the drive by turning it against the left or right stop, hold for 5 seconds until 1x green LED, release, 3x red LED

o Cyclic, during operation and parallel to regular 4BS communication in a default time interval of 12 hours

NOTE: The SIG telegram interval can only be changed by means of ReCom (see product specification).

The maximum waiting time for an UNLOCK response to a signal telegram is 1 second

NOTE: Analogous to 4BS communication on A5-20-01 and A5-20-06

ReCom acknolwledges for UNLOCK, LOCK and SET CODE are enabled

ReCom starts with an UNLOCK, the required Default Security Code (SC) is 0x53C65E34

Writing the link table and parameters

requires prior modification of the Default Security Code

Invalid SCs (0x00000000 and 0xFFFFFFFF) are automatically reset to the default SC

Changing the SC plus writing the link table plus writing parameters can be done in one pass.

The sequence of processing individual parameters or sequence of link table / parameter is freely selectable.

NOTE: Note the Maturity time of the radio module with successive commands.

The maximum available time window between UNLOCK and LOCK is 8 seconds

If there is physical access to the device, the SEC CODE can be manually reset to its default value

Proceed as follows:

1st. Bring the device into the assembly position

2nd. Turn the adjusting wheel to the left against the stop and hold

→ After 5 seconds 1x green LED, after another 5 second 1x green LED

3rd. Turn to the right within one second and hold for 5 seconds

→ 1x green LED

4th. Within 2 seconds, turn 2x briefly to the left against the stop

→ 2x green LED followed by 2x tone signals

→ The SEC CODE has been reset to its default value 0x53C65E34
