APPLICATION DESIGN AND COMPATABILITY
  • The sensor is designed for indoor carbon dioxide concentration measurement and respective air capacity regulation through the control output signal to the fan.
  • Air capacity control based on CO2 concentration is an efficient energy saving solution.
  • The sensor has two separate outputs: a normally opened dry relay contact and an analogue output 0…10 V (this output is adjustable for 2…10 V/0…20 mA/4…20 mA).
  • The relay output is used to turn the fan on/off depending on indoor CO- concentration and the analogue output is used for smooth fan speed control for a fan with EC-motor or a fan with extra speed controller with 0-10 V input, refer to RS...TA or VFED.
  • In case of smooth fan speed control the fan speed varies proportionally to carbon dioxide emissions.
  • The relay and analogue outputs make the sensor compatible with any ventilation system.
  • The integrated self-calibration system ensures reliable sensor operation during the sensor service life.
MODIFICATIONS
  • The sensor is available in two modifications: CO2-1 and CO2-2.
  • The CO2-1 model incorporates LED lights for CO2 concentration and operation buttons indicating the level of three operation modes: 1 – on, 2 – off, 3 – operation by CO2 concentration.
  • The button is used to switch the ventilation system on or off when CO2 - based ventilation control is not required.
  • The CO2-2 model has no LED-lights and on/off button.
  • The model is applied for premises requiring permanent ventilation, i.e. at school classes and other public premises.
MOUNTING AND POWER SUPPLY
  • The sensor is designed for wall surface mounting.
  • 24 VAC low current power supply.
  • If power supply 24 V is not available, connect the TRF plug that is offered as an accessory.
ACCESSORIES
  • Power supply unit is applied for connection of the sensor to 220 V (model TRF-220/24-1,6) or 120 V (TRF-120/24-1,6) AC power mains.
