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
