GENERAL FEATURES

• up to 70 litre/sec at 50Pa - max 75 litre/sec capacity
• sfp down to 0.55 W/l/s
• summer bypass which allows the airflow to bypass the heat exchanger automatically when internal and external temperatures are between adjustable setpoints.
• frost-protection - proportionally reduces intake motor speed as temperature falls - activated when the outside temperature between +8ºC and -3ºC.
• run-time and power outage counters
• easy to install and maintain
• 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 from:
  • A light switch (if more than one light switch is used, each one must be a double pole switch)
  • Remote humidistat (230V - DRH240)
  • Passive infra red (230V - PIRFF)
  • 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 90 minutes.
• adjustable boost speed delay from 0 to 5 minutes
• remote purge cable connection on circuit board (for optional purge facility)
• 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
• relay for external pre-heater
• 3 speed selector switch
• optional remote purge cable - factory connected - adjustable over-run timer from 0 to 250 minutes. Pre-set to 15 minutes (adjustable at factory)
• 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 QRcode.
