Systemair EC-Vent control board

Built-in transformer (230V/24V) 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 c...
