Codis 35 VAV

Variable air volume damper applications

KOER-VAV
D E S C R I P T I O N

Codis 35 VAV was designed to control Variable Air Volume dampers. Its hardware platform is the same as Codis 35 FC with the addition of a CO2 sensor. Like the FC, it enables higher energy efficiency thanks to a powerful weekly scheduler, “Occupied” operating mode and a digital input for presence sensor connection or passive electromechanical switch (open window) connection.

Typical Application

KOER-shema_VAV

OFFICES

Staying late and alone at work without heating or cooling can only increase the level of stress for employees. With Codis and Compact BMS timer settings can be overridden and that one office can be kept heated or cooled. Good air quality and the right temperature help employees to stay productive and focused for longer periods of time.

RESTAURANTS

For the guests, the aroma of freshly prepared food is enjoyable and it can be a good marketing tool for the restaurant. But if the restaurant is not properly ventilated, the enjoyable aroma will become an unpleasant smell after just a few days. Codis 35 and the volatile organic compound (VOC) sensor ensure that the right balance of fresh air and a good atmosphere are part of the business image.

HOTELS

Home away from home is something that all guests are looking for in hotels. To achieve that feeling, guests should be able to adjust heating, cooling or ventilation settings in a simple and intuitive way. The clean and modern design of Codis and intuitive controls of Compact BMS are a perfect combination for HVAC management in rooms and for control of zones in hotels.

RESIDENTIAL

No matter which season it is, a home should always be kept within perfect temperature limits for family and friends to enjoy it. With Codis and Compact BMS home temperatures can be easily adjusted for different zones and different occasions. Also, better control of all home zones achieves significant savings for household costs.
