General

  • up to 74 litre/sec at 50Pa - max 80 litre/sec capacity
  • sfp down to 0.71 W/l/s
  • summer bypass activated when inside temperature is above 24ºC (and outside temperature between 14ºC and 24ºC);
  • frost-stat - proportionally reduces intake motor speed as temperature falls - activated when the outside temperature between +2ºC to -8ºC.

  • for ceiling, loft or void in-line installation
  • variable low (trickle), boost and purge options for each motor
  • boost speed can be activated by a 230V switched live, or a 0-10V connection from:
    • a light switch (if more than one light switch is used, each one must be a double pole switch)
    • Remote humidistat (230V - DRH240)

    • Thermostat (230V - THM)
    • Remote switch/pull cord - 230V
  • very low noise levels
  • low running costs
  • 5 year warranty - 1 year parts and labour, 4 years parts only

CONTROL FEATURES - STANDARD

  • independent variable speed adjustment for each motor for trickle, boost and purge speeds.
  • adjustable boost speed over-run timer from 0 to 30 minutes.
  • adjustable boost speed delay from 0 to 5 minutes
  • adjustable purge speed over-run timer from 0 to 250 minutes, pre-set to 15 minutes (adjustable at factory).
  • adjustable night time boost and purge inhibitor
  • integral frost-stat - proportionally reduces intake motor speed as temperature falls
  • automatic summer bypass

CONTROL FEATURES - FACTORY SET

  • change of ductwork handing on humidistat version (trip point can be set at manufacture)
  • integral humidistat - proportionally increases motor speeds with rising humidity
  • 0-10V connections can be added for:
    • BMS - for remote motor shut-off
    • CO2 detector
    • home automation system
    • external pre-heater
    • 3 speed selector switch
  • purge speed over-run time
  • holiday mode for reduced speeds when property is unoccupied (factory set option) - default setting is 50% of trickle speed
  • run-time and power outage counters downloadable via QR code.
