Universal Fan Coil Controller – 3 X 0-10V | 5 IN – 3 OUT

Two 0-10 V outputs are dedicated to the management of proportional valves, variable speed management be done with the third 0-10 V output or with the 3 relays on board. If relays are not used for speeds, they can activate lights or other loads. An input is also available for reading 0-10V or 4-20mA signals to interface external probes for temperature, humidity, CO2 , etc; the third 0-10 V output can also be configured in this mode, as input. There are also 5 digital inputs for dry contacts in order to connect buttons, window contacts, alarms;

2 inputs can be connected to NTC temperature probes (eelectron codes TS00A01ACC and TS00B01ACC). The logic inside the device can manage a 2/4 pipes fan coil with an internal 2-stage PI algorithm. A sophisticated parameterization allows its use in modern systems that require a differentiation of the behavior between speed and valves (independent regulation differentials), ventilation to avoid air stratification, logics for efficient maintenance of comfort and energy saving.

The device also integrates the “Virtual Holder Logic”; the field of application is the hotel room: through a magnetic sensor installed on the door and connected to a digital input, accurate presence information is managed. The presence detection solution can deduce the presence of people in the room using one or more dedicated sensors. It also detects an unexpected presence and is able to differentiate more behaviors. Moreover, 10 logic blocks are available to implement simple expressions with logical or threshold operator or complex expressions with algebraic and conditional operators; It is possible to use predefined algorithms as proportional controls of temperature and humidity or dew point calculation. Device is equipped with KNX communication interface.
