1 GENERALITIES

1.1 Description

The application is dedicated to the control and regulation of the Air Handling Units with cross flow

recovery heat exchanger. There are two solutions available:

• COMPACT Control: Responds to minimum requirements and the Standards.

• COMPLETE Control: Integrates the heating and high recovery efficiency functions to the

Base solution.

The solution makes use of the large modularity of the c-pro micro programmable controllers: the

compact control unit uses just one C-PRO MICRO CAN controller, connected to a LCD graphical

user terminal VGRAPH, while to obtain the complete control solution a C-PRO EXP MICRO

(CAN) must be connected to the C-PRO MICRO (CAN).

The C-PRO MICRO (CAN) controller has the following I/O:

• Digital outputs: 6

• Digital inputs: 5

• Analogical inputs: 4

• Analogical outputs: 1+2

The C-PRO EXP MICRO (CAN) expansion has the following I/O:

• Digital outputs: 6

• Digital inputs: 5

• Analogue inputs: 4

• Analogue outputs: 1 (+2 optional)

Both instruments are equipped with CAN field port and a second TTL port, which via a TTL /

RS485 serial interface (MODbus) allows connection to BMS or EVCO (RICS) supervision systems.

The main control functions managed by the “Complete” solution are:

- Supply fan management

- Return fan management

- Management of the cross flow recovery heat exchanger by-pass damper

- Outside air damper management

- Management of hot water coil for heating (or a group of 3 electric heaters)

- Management of time bands with ECONOMY and COMFORT working mode

- CO

probe management for fan control

- Alarms log

- User Menu split in three main levels (User, Installer, Manufacturer), each protected by a

different password.
