Distech Controls ECC-VAV - Network Variables for Wireless Sensor Inputs - Tridium Niagara Use-Case

RF & LCD Input Values Output
network output UNVT_gen_values nvoComInputs;
This output network variable indicates the value of each RF or LCD input used on the VAV.
Typical Range
The typical range is -3276.8 to 3276.6 for each field. The units depend on the input type.
Default Value
All fields will be set at zero at start-up until a valid value is present. Unused fields will stay at zero. Note that, on the VAV, there is only 6 RF & LCD inputs so only 6 fields are used out of 15.
When Transmitted
The variable is transmitted immediately when its value has changed. Additionally, this network variable will also be transmitted as a heartbeat output on a regular basis as dictated by the general Maximum Send Time configuration property SCPTmaxSendTime.
Update Rate
This value will be updated no faster than the general Minimum Send Time configuration property SCPTminSendTime.
Default Service Type
The default service type is unacknowledged.

Module Manager

The module manager is used to manually associate wireless sensors to the VAV by entering the appropriate Module IDs and Module Types or automatically by using the Learning mode.
 
Module Manager
Enter Module ID
The Module ID is a unique hexadecimal identifier used to identify each wireless sensor (similar to a Neuron ID for a LonWorks device). The Module ID of a wireless sensor must be associated with the controller for communication to take place.
If a wireless sensor is to be manually associated with the VAV, locate the Module ID which is printed on a sticker attached to the device and enter it in this field. Click on  to add the Module ID to the Registered Modules table. The module type must also be specified in the Type column of the Registered Modules table.
Learned Modules
Index: The Index column lists the order in which the modules were learnt.
ID: The ID column lists the Module IDs of wireless sensors that have been automatically learnt.
Learned modules are not permanently associated with the VAV until they are added to the Registered Modules table by clicking .  Learned module IDs are stored in UCPTlearnedComModule[0] to UCPTlearnedComModule[11].
Registered Modules
The Registered Modules table lists all wireless sensors that have been successfully associated with the VAV.
Index: The index column lists the order in which the modules were associated with the VAV.
ID: The ID column lists the Module IDs of wireless sensors that have been associated with the VAV. The IDs of used modules are stored in UCPTusedComModule[0] to UCPTusedComModule[5].
Type: The wireless sensor type. If the type has not yet been entered, it will be listed as UNKNOWN. Click within the type field to access a drop-down menu from which the appropriate wireless sensor type can be selected.
Clear list before learning
Check this option to clear the Learned Modules table before entering Learning Mode.
 
Accept learn button only
(Recommended)
When this option is checked, the Module ID of a wireless sensor is only added to the Learned Modules table when the wireless sensor's learn button is pressed.
 
A universal wireless switch module does not have a learn button. For these devices, press the desired switch to be learned instead.
This option filters out automatic transmissions and transmissions due to a change of state, turning of a knob, etc.
Status
Displays the current state of the VAV.
Start learning modules
When this button is pressed, the controller will enter Learning Mode for 30 minutes. Each time that the VAV learns a new device, the Learning Mode is extended for another 30 minutes. There must be a delay of approximately 5 seconds before learning consecutive devices since the VAV may not have finished processing the first device.
 
If a Smart Sensor is connected to the VAV, the user must disconnect it and wait 2 minutes before starting to learn wireless modules.
 
Highlight one or more Registered Modules in the table and click on this button to remove them from the list.

Module ID
The Module ID is a unique hexadecimal identifier used to identify each wireless sensor (similar to a Neuron ID for a LonWorks device). The Module ID of a wireless sensor must be associated with the controller for communication to take place. The controller discards messages that are received from unknown sources.
Model
The wireless sensor type. The following wireless sensors are supported by wireless VAV models:
RF_TP_SENSOR: Temperature sensor.
RF_TP_SP_SENSOR: Temperature sensor with setpoint adjustment.
RF_TP_SP_OV_SENSOR: Temperature sensor with setpoint adjustment and override button.
RF_TP_SP_SLDSW_SENSOR: Temperature sensor with setpoint adjustment and slide switch.
RF_TP_SP_OV_FANSPD_SENSOR: Fan speed sensor with setpoint adjustment and override button.
RF_TP_RH_SENSOR: Relative humidity sensor.
RF_TP_RH_SP_SENSOR: Relative humidity sensor with setpoint adjustment.
RF_TP_RH_SP_OV_SENSOR: Relative humidity sensor with setpoint adjustment and override button.
RF_TP_RH_SP_SLDSW_SENSOR: Relative humidity sensor with setpoint adjustment and slide switch.
RF_OUTDOOR_TP_SENSOR: Outdoor temperature sensor.
RF_CABLE_TP_SENSOR: Cable-type temperature sensor. The temperature is averaged over the length of the cable.
RF_AIRDUCT_TP_SENSOR: Air duct temperature sensor.
RF_CONTACT_TP_SENSOR: Contact temperature sensor.
RF_DIGITAL_INPUT_SENSOR: Digital input.
RF_WINDOW_CONTACT: Window contact (can be used for doors also).
RF_LIGHT_SWITCH: Light switch.
RF_MOTION_DETECTOR_360: Motion Detector.
 
Use OCCUP_CONTACT input type to configure the motion detector.
Module Manager
Launches the Module Manager window.
The point configuration options vary depending on the wireless sensor input you chose in the Wireless tab.
