DC-VAV • DC VAV

  • DUCO
  • Valve
  • For DC-BOX FOCUS

Patented control valves for demand-driven ventilation systems. Each valve is equipped with a CO2 or moisture sensor for a measurement IN the air flow. It is also possible to integrate a sensorless valve.

Application

The control valves ensure that only polluted and/or moist air is discharged, where and when required and in the right amount. The control valves are used as standard with the Duco Comfort Plus & Duco Tronic Plus systems.
  • All 'dry rooms', such as the living room/open kitchen or the bedrooms, can be fitted with a CO2-controlled valve (DC-VAV CO2 75 and DC-VAV CO2 30): This constantly monitors the indoor climate and ensures for the polluted air (at a ppm> 800 ppm) to be extracted in the relevant room and only there
  • The 'wet rooms', such as the bathroom, can be equipped with a controlled valve (DC-VAV RH 50): As soon as, for example, a shower is carried out, the moisture sensor on the valve automatically ensures that the moist air is extracted in the bathroom. until the condition is normalized again
  • In addition, there is also a possibility to provide a sensorless valve (DC-VAV SC 25) for efficient drainage in, for example, the toilet: This valve can also be adjusted to any flow
  • For the toilet, an extremely sensitive CO2 valve DC-VAV CO2 25 can optionally be provided, which already responds to a change of 5 ppm.

Specifications

Wireless communication (via RF protocol) or wired communication (via Duco protocol) with other control components in the Duco network

  • Measuring area:
    • CO2 and temperature
    • Relative humidity and temperature
  • Measuring range: 400-2000 ppm or 0-100% RH
  • Installation: in the DC-BOX FOCUS
  • Placement:
    • DC-VAV CO2 75 and DC-VAV CO2 30: Connected to the drain for the living room/open kitchen and bedroom(s)
  • DC-VAV CO2 25: Following the drain for the toilet
  • DC-VAV RH 50: Following the drain for the bathroom or laundry room
  • DC-VAV SC 25: Valve without integrated sensor that can fulfill several functions, can be used in combination with DC-SEN room sensors, DC-CV control switch, DC-SC switch contact
  • The standard flow rate of the control valves can be changed manually during or after installation via the display menu or via the Duco Ventilation App
  • NOTE: For optimum system operation, all zones must be provided with a separate air duct network
