The expansion module EM-LON supplements the EASYLAB base components (controller TCU3 or adapter module TAM) with a LonWorks interface to link rooms or individual volume flow controllers to the central BMS.

The LonWorks interface supports the EASYLAB room operating mode concept. It is possible to set operating mode defaults in order to control different volume flow rates for daytime and night-time operation; it is also possible to increase or reduce the air change rate by a certain amount (volume flow rate setpoint change), e.g. to influence the room temperature.

Using the LonWorks interface, an individual alarm management system can be set up by consolidating configurable EASYLAB alarms. The interface also enables the transfer of actual operating values such as volume flow rates and damper blade position for a controller or for all controllers in a room.

LonWorks interface

Description of network variables (SNVT)

All variables and parameters are based on standard network variables (SNVT); this ensures integration of the expansion module EM-LON into a LonWorks network.

The equipment functions that support each variable are listed under the special information for that network variable.

Abbreviations

  • FH: Fume cupboard controller
  • EC/SC: Extract air controller / supply air controller
  • RR: Room controller for supply air or extract air
  • TAM: Adapter module
  • RR-RMF: Room controller with active room management function
  • TAM-RMF: Adapter module with active room management function

Operating mode default setting

  • Input variables nviManOverride (SNVT_hvac_overid), nviOccCmd (SNVT_occupancy) and nviMode (SNVT_state) are available for operating modes
  • nviManOverride has the highest LON priority
  • nviMode has the lowest LON priority.
  • A configuration of the assignment is possible only for nviOccCmd by means of the parameter nciConfig_Occ (SCPTdirection).
  • The valid binding of an input variable results in a valid operating mode default setting in LON for a single controller or for the room
  • The invalid binding of an input variable does not result in an operating mode default setting in LON

Operating modes Standard mode

Standard mode means normal operation in the daytime (in Germany: usually according to DIN 1946, part 7, 25 m³/h extract air per m² main useful floor area)


Reduced operation

Low mode in comparison to standard mode, e.g. as a night-time setback


Increased operation

High mode in comparison to standard mode, e.g. in an emergency


Shut-off mode

Installation details

  • Installation details

Installation and commissioning

Installation

  • As attachment for the EASYLAB base component: factory mounted
  • For retrofitting: Mount the expansion module into the base casing
  • Connect to the LonWorks network


Commissioning

  • The EASYLAB controller identifies the expansion module automatically
  • Integrate system with the LonWorks network and link the data points logically (binding) using a network management tool (e.g. Echelon LonMarker, to be provided by others)
  • Load EASYLAB LonWorks application
  • Applications are available for download from our website
