Operating instructions MVA009

No

Objective

Button

No.

Action

LED or Tone activity

Reasons for failure

1

Pairing from mounting position

(OFF)

OR from normal operation

Turn dial to end position

Left OR Right and hold 5 seconds, then turn to the opposite stop and release immediately.

Unit transmits a teach telegram (1x green LED), connects with the controlling unit and confirms the successful teach-in with a second flash green LED.

The unit remains in mounting position. Any actuator not in mounting position will activate the motor and return to mounting position to switch off the device.

After 5 seconds 1x green LED for teach sent

Teach-in successful:

1x green LED

Failure (not teached):

3x red LED

No tone signals.

Controller or gateway either not present or not in pairing mode, so that pairing fails

2

Mounting

Mount the actuator before executing run-in sequence and normal operation.

Consider required adapter (Section 14)

3

Reference run and normal operation

Turn to end position

Left OR Right for short press (< 1 second)

Unit executes run-in sequence and enters normal operation.

Radio communication will occur every 2 minutes and for a time duration of 30 minutes after activation. Communication after 30 minutes follow the 4BS settings transmitted by the room control unit.

Success:

1x green LED

Failure:
3x red LED

No tone signals

Mounting failure (e.g. missing adapter),

Motor failure, Gear failure

Unmounted will return the motor to mounting position and switch off the device.

1

Local Offset

Operation in Temperature Setpoint (°C)

(Internal control loop)

Turn to end position

Left OR Right for short press.

Turn dial left for 1 or up to 5 times until its end position:

Every successful actuation will decrease the actual setpoint temperature by 1°C and transmit the new setpoint as absolute value.

Turn dial right for 1 or up to 5 times until its end position:

Every successful actuation will increase the target temperature by 1°C.

The temperature setpoint may be changed by up to +/- 5°C.

Multiple local inputs within one cycle time frame of 5 seconds are internally cumulated to one desired target value. 

Individual local input cycles are open for a max. time window of 5 seconds and concluded with a telegram transmit including the desired target temperature as absolute °C temperature value.

Resulting changes in motor position will only be executed when the room controller confirms the local change with its responding and next data telegram.  

Success:

1 … 5 tone signals according the number of inputs

Failure:

Red flashing LED for 2 seconds. (Left and right inputs in one cycle).

Wait for 10 seconds.

No tone signals:

No local actuation detected or accepted.

Device is in mounting position.

2

Local Offset

Operation in Valve Position (%)

Turn to end position

Left OR Right for short press.

Turn dial left for 1 or up to 5 times until its end position:

Every successful actuation will signalize the controller the desired reduction in target temperature with a relative value (e.g. 0x7F for -1)

Turn dial right for 1 or up to 5 times until its end position:

Every successful actuation will signalize the controller the desired increase in target temperature with a relative value. (0x01 when +1)

The desired temperature setpoint change communicated to the controller may be changed by up to +/- 5.

Multiple local inputs within one cycle time frame of 5 seconds are internally cumulated to one desired target value. 

Individual local input cycles are open for a max. time window of 5 seconds and concluded with a telegram transmit including the desired target temperature as absolute °C temperature value.

Resulting changes in motor position will be executed when the room controller confirms the local change with its responding and next data telegram. 

Success:

1 … 5 tone signals according the number of inputs

Failure:

Red flashing LED for 2 seconds. (Left and right inputs in one cycle).

Wait for 10 seconds.

No tone signals:

No local actuation detected or accepted.

Device is in mounting position.

1

Deactivate, Move to mounting position, Switch off

Disassembly

Turn to end position

Left OR Right and hold for at least 5 sec. up to 1x green LED,

then turn to the opposite stop and release immediately

Green LED appears, than release.

3x red LED indicates teach-in failure which however does not play any role when deactivating the device. Motor moves back to mounting position and device switches off.

Reactivation in mounted position will restart the device with no changes to previously set parameters including link table settings to enter normal operation.

Success:

After 5 seconds 1x green LED followed by 3x red LED

Failure:

No LED

No tone signals

No LEDs:

Try again and hold the dial end position tight. Do not release during the 5 seconds time period.

2

RESET followed by normal operation.

Turn to end position

Left OR Right and hold for 10sec. After the green LED flashes a second time, turn it briefly to the left stop and release it immediately

Turn dial to left or right until its end position and hold for at least 10 seconds until the 2nd green LED appears, then release.

When mounted, teached and active:

Device enters installation radio cycle of 2 minutes for a 30 minutes duration. Transmitted ambient temperature is the raw and actual temperature (no approximation, no smoothing).

In case of Radio communication failure: Device switches to Temperature setpoint and 21°C.

Success:

1x green LED after 5 seconds followed by a 2nd green LED after another 5 seconds

(10 seconds in total).

No LEDs:

Try again and hold the dial end position tight. Do not release during the 10 seconds time period.
