FUNCTIONALITIES
Adjusting and displaying fl ows
- Constant or fi xed airfl ow (CAV mode), up to 2 diff erent set point fl ows
- Variable airfl ow according to an external 0-10V signal, of the
command control or remote control (VAV mode)
- Management of airfl ows according to time slots (Clock)
- BOOST function by external contact
- STOP function by external contact
Adjusting internal water coils
- Adjusting the power by activating a 3-ways valve
*
Adjusting internal electric heaters
- Proportionally adjusting the power of the electric heaters
Adjusting an external electric heaters (accessory)
- Proportionally adjusting the power of the electric heaters by a 0-10V
signal

- Coordinating a damper servo-motor (accessory) in relation to fresh air
Controls and Safety
- Filter clogging signal
- Fault signal on temperature sensors
- Ventilation fault signal
- Signal indicating that a set point has not been observed (Airfl ow,
Pressure, Temp.)
- Fire alarm from a contact related to the external fi re detection system
- Alarm indicating a fault in the communication between the controller
and command control
- Freeze risk control on the water coil (opening the valve, stop if the
water temperature drops below 7°C in heat mode)
- Alarm history
COMMUNICATION
- Remote control with graphic touch screen (ETD)
- MODBUS RTU in standard mode (RS485)
- BACNET IP on TCP/IP port
- Web server application on TCP/IP port
Included,
Options
(*) Run around coil management:
The controller can manage the run around coil pump :
• ON /OFF driving (without by-pass valve),
• ON/OFF driving with by-pass valve management,
• Variable pump speed driving without by-pass valve.
(**) 0-10V proportional signal coming from 0-10V heating coil (parallel connection).
