Functional profile according to LONMARK®
The LON-capable actuator is certified by LONMARK®. Die following actuator functions are made available via the LONWORKS®
network as standardised network variables in accordance with LONMARK®: the Node Object #0, the Damper Actuator Object
#8110, the Open Loop Sensor Object #1 and the Thermostat Object #8060.

Node Object #0
The node object contains the object status and object request
functions.
nviRequest: SNVT_obj_request
Input variable for requesting the status of a particular object in the
node.
nvoStatus: SNVT_obj_status
Output variable that outputs the current status of a particular object
in the node.
nvoFileDirectory: SNVT_address
Output variable that shows information in the address range of the
Neuron chip.

Damper Actuator Object #8110
The actuator object is used to display the functions of the actuator
on the page of the LONWORKS® network.
nviRelStpt: SNVT_lev_percent
The nominal position is assigned to the actuator via this input
variable. This variable is normally linked to the output variable of an
HVAC controller.
nviActuateState: SNVT_switch
A preset position is assigned to the actuator via this input variable.
Note on priority: The variable which was most recently active, either
nviActuatorState or nviRelStpt, has priority.
nviManOvrd: SNVT_hvac_overid
This input variable can be used to manually override the actuator
into a particular position.
nvoActualValue: SNVT_lev_percent
This output variable shows the current actual position of the actuator
and can be used for control circuit feedback or for displaying
positions.
nvoAbsAngle: SNVT_angle_deg
This output variable shows the current angle of rotation / stroke of
the actuator and can be used to display the position or for service
purposes.
nvoAbsAirFlow: SNVT_flow
This output variable is inactive with this actuator and shows a
constant value of 65535 (this variable is only active in conjunction
with LON-capable VAV controllers).

Open Loop Sensor Object #1
One sensor can be connected to the actuator.
A passive resistance sensor (e.g. Ni1000), an active sensor (output
0 ... 32 V) or a switch (On/Off) can be connected. In the case of
the open loop sensor object, the measured sensor values are
transferred to the LONWORKS® network.
nvoSensorValue: SNVT_xxx
This output variable shows the current sensor value. Depending on
the connected sensor, the output variable can be configured via the
sensor plug-in and specifically adapted to the system.
The SNVT_.. can be configured as:
SNVT_temp_p
SNVT_lev_percent
SNVT_lux
SNVT_temp
SNVT_abs_humid
SNVT_press_p
SNVT_switch
SNVT_enthalpy
SNVT_smo_obscur
SNVT_flow
SNVT_ppm
