 7. CONTROL FUNCTIONS

MAIN ELEMENTS

Control panel includes:

General switch

Electric box including control and wiring components, with access from side panel.

FUNCTIONS

Airfl ow adjustments

Manual fans speed adjustment

Automatic fans speed adjustment in VAV mode. Fans adjust their speed from the signal measured by an external 
sensor (CO

2

, Relative humidity or Temperature)

Automatic speed adjustment of the fans in COP mode (Constant Pressure). Fans adjust their speed to maintain a 
constant pressure in the duct net. It is necessary to install an external TDP sensor (accessory)

BOOST function (Forced speed preset via external power free contact) (available just in models 04 to 27)

ON/OFF  function (Remote ON/OFF via external power free contact)

Temperature regulation

Temperature probes integrated within the unit (supply, extract, inlet and outlet)

Bypass adjustments

Manual actuation of bypass

Automatic actuation of bypass function free-cooling/ free-heating and heat exchanger anti-freezing protection

SECURITY FUNCTIONS

Control of polluted fi lters via  pressure switches (included)

Alarm display in remote control

Fault detection in temperature probes

Fault detection in fan via pressure switches (included)

Anti-frost protection of heat exchanger via bypass activation.

COMMUNICATION

Remote wiring control

ON/OFF remote digital input via external power free contact.

Alarm digital output via power free contact.

Modbus RTU (RS-485)
