24V supply to damper and sensors etc

Can control two fans

Can control heater/cooler

The EC Vent is more than just a control for EC fans. It is a tool that, together with EC fans, simplifies demand-controlled ventilation making it easy to set up and operate. The unique feature of the EC-Vent is that it allows for a number of control options with up to five sensors (analog or digital). A single parameter such as temperature can be controlled at several different locations. Alternatively, various parameters, (CO2, humidity, temperature, etc.) can be combined to control the fan directly or as a complement to the weekly schedule and/or the manual control to boost the ventilation if needed. It can also be used to control a heater or an extra fan via 0-10 V signal.

The EC-Vent consists of two units, one central unit to be placed near the fan and a single display unit normally sited in a room easily accessible to the user. These units are connected to each other with a low voltage cable. The EC-Vent offers the opportunity to connect up to 5 different sensors that simultaneously detect the actual ventilation requirements and in this way the EC fan will be steplessly controlled to ventilate exactly as much as is needed, no more, no less. The result is a good indoor air quality and the user avoids high electricity bills.

The central unit for the EC-Vent can be operated stand-alone from the room unit.
