2.1 COMPACT solution
The picture above shows a principle layout. It is intended for indicating the presence of the components, not their position, in
the AHU controlled by the EVCO device. It is also NOT intended for indicating the real layout of the AHU.
The unit has the following main features:
•
N° 2 Fans with 3 speeds or with 1 speed + speed variator
•
N° 1 Heat exchanger/Cross flow recovery heat exchanger
•
N° 1 Recovery heat exchanger By-pass damper (optional)
•
N° 1 Recovery heat exchanger anti-freeze temperature probe
•
N° 1 Presence sensor (installed in the room)
•
N° 1 Start – Stop (remote)
Note: The compact solution is by default configured for piloting 3-speed fans (PG10 = DO)
