Duplexvent DV180/370/510SE Interactive Line Side Entry - Up to 510 m 3 /hr air volume

Internet Connection Duplexvent Interactive Line units incorporate an Internet server that uses Modbus TCP/IP protocol to provide a connection between the ventilation unit and the internet via a standard plug and play ethernet cable. This allows you to monitor and control the unit from a computer, laptop or smartphone via the internet or a local area network. The unit can also be monitored remotely by technical service which saves time and cost on service processes.

All the Interactive Line units incorporate an integrated web server with user and service interfaces which enable unit control and monitoring from a remote location. With this unique feature you can control your unit via a computer, laptop or smart phone in order to maintain the optimum operation at all times. Similarly a service technician can connect to the unit remotely, check the status, diagnose any faults and instruct the user what to do immediately, saving service and down time costs. The units include a digital controller with LCD display which incorporates 10-speed air flow control, weekly ventilation programming, filter maintenance indicator, automatic frost protection facility and automatic boost function with delay timer. Controls The digital control provides the following features: ● 10 speed EC fan control ● Daily / Weekly programme setting ● Automatic boost function with timer delay (via volt-free contact or 0-10V sensor output) ● Automatic frost protection reduces the supply ventilation rate for a certain period to prevent ice build-up within the heat recovery cell depending on the outside air temperature ● Automatic, 100% summer bypass provides free cooling in the summer season. Its motorised damper is triggered by the temperature sensor automatically ● Heater control for frost heater and post-heater

The units are also continuously checked for any faults by the integrated Failure Diagnostic System which alerts the user as soon as it detects any unusual operation hence providing a real time maintenance update. On-demand ventilation can be achieved by using humidity, CO 2 and air quality sensors which boost the air volume gradually based on the moisture and occupancy levels in the dwelling. It is also possible to integrate the unit into a Building Management System (MODBUS TCP/IP) to monitor and control the unit’s functions by a central control system. Having the latest, low energy EC fan technology, the DV180SE, DV370SE and DV510SE comply with the ErP 2015 standards, are tested by TUV laboratories and come with an outstanding 5 year warranty + . ● Filter monitoring and alert via pressure sensors ● BMS connection (Modbus TCP/IP) ● Internet connection with user and service interfaces ● Outputs for electric / water heater ● Zonal ventilation control (winter / summer) ● Constant flow / pressure control ● Indoor temperature control based on extract air / supply air / room temperature via 5 different sensors ● Demand ventilation via CO 2 , humidity and air quality sensors

Heaters The new generation PTC (Positive Temperature Coefficient) electric heater incorporates a power adjustment facility which automatically increases/decreases the power based on the air volume going through the heater hence shortens the heating response. Also the heater has two protection thermostats and a perforated metal filter which can easily be maintained via the inspection door. This significantly increases its life span especially when the heater is installed on the outdoor air side for frost protection purposes. Alternatively it can be used as post-heater to achieve the required indoor air temperature.
