Input Network Variables (nvi’s) Description Parameter Variable Name Function Room network input This input network variable provides a network remote temperature Temperature SNVT_temp_p value to the thermostat. When linked of written to, the internal nviSpaceTemp temperature reading (internal sensor) is no longer used. Valid Range: 40 to 122°F (-40 to 50°C) Default Null (release) Value: 621.81°F (327.67°C or 0x7FFF) This network variable is subject to the Receive HeartBeat Time,... -
Page 9: Nvifanspeedcmd
Parameter Variable Name Function Fan Mode network input This input network variable is used to connect an external fan SNVT_switch speed switch to the node or to allow any supervisory device to nviFanSpeedCmd override the fan speed controlled by the node’s control algorithm. This input is used in conjunction with FanMenu bit in nciGenOpts. -
Page 10: Nvioccmancmd
Parameter Variable Name Function Occupancy network input This input network variable is used to command the Space Command SNVT_occupancy Comfort Controller into different occupancy modes. It is typically nviOccManCmd set by a supervisory node to remotely control the occupancy modes to override the local occupancy routines of the thermostat. Default Null Value: OC_NUL = 0xFF Valid Range: 0 = OC_OCCUPIED *... -
Page 11: Nviapplicmode
Parameter Variable Name Function Sequence of network input This network variable input is used to coordinate the Space operation SNVT_hvac_mode Comfort Controller with any node that may need to control the nviHeatCool heat/cool changeover of the unit. This input is overridden by nviApplicMode, unless nviApplicMode is HVAC_AUTO. - Page 12 Output Network Variables (nvo’s) Description All output network variables will be updated no faster than the Minimum Send Time (nciMinOutTm) configuration value. An output network variable will be transmitted immediately when its value has changed significantly (manufacturer’s defined). Additionally, this variable will also be transmitted as a heartbeat output on a regular basis as dictated by the Maximum Send Time (nciSndHrtBt) configuration value.

78000 bits per second Network segment length varies depending on wire type. Table 1: Summary of Specifications for a Vykon’ LON Network Network Configuration The Echelon network is designed to support free topology wiring and will accommodate bus, star, loop or any of these topologies. - Page 23 Maximum Number Of Devices Up to 64 transceivers are allowed per network segment. If your network requires more than 64 transceivers a repeater is then required to extend your network...
- Page 24 Maximum Cable Length The maximum length of a chain is related to its transmission speed. The longer the chain, the slower the speed. Using proper cable, Echelon supports a baud rate of 78 kilobits per second for distances up to 1600- ft (500 m) in free topology and 8800 ft (2700 m) in bus topology with double terminations.

The name of the file is: VT7xxxReadme.txt Plug-Ins File: LNS Plug-Ins simplify start-up, maintenance, configuration and reduce the installation effort.
- Page 26 Device Identification An Echelon device has a unique mechanism to identify itself, the Neuron ID, which is obtained during commissioning. There are two ways of getting the Neuron ID: with a Service Pin or manually. Service PIN The service pin is used to identify the device at commissioning. By pressing simultaneously the “Up” button and the “Down”...
