Multiple sensor connection

The EC Vent is ready for connection to CO2, moisture, temperature, presence and pressure sensors.

User-friendly menu

The EC Vent allows for some control options and is straightforward to operate via a simple, user-friendly menu.

Lowers energy consumption

The unit’s multiple sensor options can detect precise ventilation requirements maximising the efficient use of energy.

Additional control

EC Vent can also be used for additional control of a heater or an extra fan via a 0-10 V signal. EC Vent also can be connected to the BMS via Modbus.

The EC Vent is an intelligent control that when combined with EC fans, simplifies demand-controlled ventilation. It makes the whole process easy to set up and operate, maximising comfort and reducing energy consumption. The unit is ready for connection to CO2, moisture, temperature, presence and pressure sensors.
This allows for many control options that enable highly responsive ventilation. A single parameter such as temperature can be controlled at several different locations, or various parameters can be combined. These can control the fan directly or can be used as a complement to the weekly schedule and/or manual control to boost the ventilation rate if required.
The EC Vent is made up of an EC Vent Control board that should be placed near the fan and an EC Vent Room unit that will normally be located in a room with easy user access. The units are connected via a low-voltage cable.
