In the heat exchanger, the exhausted air is cooled by the supplied air causing moisture condensation. The resulting condensed water is drained
towards the siphon. The condensate drain connection is found at the bottom side of the heat recovery unit. A siphon, which is connected to the
sewerage system, must be mounted onto the coupling of the condensate drain connection (HT 32 mm (1.26") drain pipe).

This RS-485 bus is intended to connect only the peripherals of the Futura heat recovery unit. The bus is four-wire, with a 24 V supply and a
maximum total current of 500 mA. The power supply is resistant to overload or short circuit.

The terminating resistor 120R is connected at the heat recovery unit. It is recommended to connect a second terminating resistor at the most
remote controller or sensor. . For more convenient wiring, a Jablotron JA-110Z-B RS-485 bus splitter and JA-190PL box can be used. In the case of
a large number of devices and a long wiring in a star connection, a suitable hub must be used.
