To calculate the 

calorific energy

 consumed by the system is required, in addition to the 

flow meter, it is necessary to know the temperature of the fluid at the outlet (supply) and 

at  the  inlet  (return)  of  the  air-conditioning  circuit.  For  this  purpose,  the  temperature 

probes incorporated in the flow meters and fittings supplied by Zennio can be used. Each 

one of these probes can be connected in any of the 5 analogue/digital inputs (1). 

A short press on the 

Prog./Test button

 (3) will make the device enter the programming 

mode. The 

Prog./Test LED

 (4) will light in red. On the contrary, if this button is held while 

plugging the device into the KNX bus, the device will enter the 

Safe Mode

. In such case, 

the programming LED will then blink in red. 

For  detailed  information  about  the  technical  features  of  the  device,  as  well  as  on  the 

installation  and  security  procedures,  please  refer  to  the  corresponding 

Datasheet

, 

bundled with the original package of the device and also available at
