Electronic device and method for control of a building management system

A method for regulating, by an electronic device, a temperature of a thermo-fluidic installation for a building comprising a heating/cooling system having mixing valves adapted to control flows of hot and/or cold water within said heating/cooling system,

• said electronic device comprising a control unit adapted to:
• receive a main signal from a building management system;
• receive a predefined reference signal representative of a desired parameter for said building;
• receive environmental signals from environmental sensors placed in said building and adapted to measure environmental parameters of said building;
• issue a control signal towards an actuator associated with a respective mixing valve in order to modify opening or closing thereof,
• said method comprising the steps of:
• connecting said electronic device with a cable that carries the main signal and a respective actuator associated with one of said mixing valves;
• receiving a reference temperature signal (Trif);
• computing an error (e(t)) between the reference temperature and an internal temperature (Tinterna) measured inside the building;
• computing a first derivative of the error (de(t)/dt);
• applying a fuzzy algorithm in order to compare the main signal with the error (e(t)) and error first derivative (de(t)/dt) signals, so as to obtain the control signal directed towards said mixing valve.

• said electronic device comprising a control unit adapted to:
• receive a main signal from a building management system;
• receive a predefined reference signal representative of a desired parameter for said building;
• receive environmental signals from environmental sensors placed in said building and adapted to measure environmental parameters of said building;
• issue a control signal towards an actuator associated with a respective gate in order to modify opening or closing thereof,
• said method comprising the steps of:
• connecting said electronic device with a cable that carries the main signal and a respective actuator associated with one of said gates;
• receiving a reference carbon dioxide level signal (Crif);
• computing an error (e(t)) between the reference carbon dioxide level and an internal carbon dioxide level (Cinterno) measured inside the building;
• computing a first derivative of the error (de(t)/dt);
