Operating mode default setting

  • Three levels for setting operating mode defaults (central BMS, room, fume cupboard)
  • Configuration options for prioritisation and shut-off
  • Operating mode default setting can affect all controllers in a room or a single controller, e.g. 24-hour operation
  • Default setting from the central BMS using network variables (LonWorks, BACnet, Modbus) or with switch contacts: room operating mode or fume cupboard operating mode
  • Default setting using the room control panel with switch contacts: room operating mode or fume cupboard operating mode

Diversity control

  • In many large laboratories the simultaneous operation of all controllers at maximum power is either not desirable or not possible because of the limited capacity of the system

Monitoring of the total extract air flow rate

  • The total extract air flow rate is monitored
  • An optical alarm is emitted on the room control panel
  • Alarms are consolidated for signalling

Limiting the total extract air flow rate

  • The total extract air flow rate is monitored
  • If it exceeds a certain value, the volume flow rate is reduced for individual fume cupboards, and the total volume flow rate is limited as a consequence
  • Reducing the volume flow rate for only selected fume cupboards ensures that as many fume cupboards as possible can be safely used at the same time
  • Optical and acoustic alarms are emitted on the fume cupboard for which the volume flow rate has been reduced
  • An optical alarm is emitted on the room control panel

Room management function

Application

  • The room management function is a software option that provides functions for the entire room
  • Within an EASYLAB system with a maximum of 24 controllers, the room management function is activated on one controller – supply air controller TCU3, extract air controller TCU3, or TAM adapter module
  • For fume cupboards, the room management function can only be activated on the TAM adapter module
  • Factory set parameters for the room management function
  • On-site activation using the EasyConnect configuration software

Central interface point for room functions

  • Room operating mode default setting for all controllers in the room; priority can be selected
  • Room operating mode default setting using switch contacts LonWorks, BACnet, Modbus, or room control panel
  • Volume flow rate setpoint change based on temperature control
  • Volume flow rate setpoint change based on external differential pressure control
  • Connection of a room pressure transducer, door contact, and setpoint value switching contact for internal differential pressure control
  • Control input signal for sun protection/blinds (to be provided by others) and lighting

Centralised configuring of the room parameters and functions

  • Default setting for the minimum total extract air or the minimum total supply air for the room
