COSTER REGULATOR HUMIDITY RELATIVE HUMIDITY CENTRAL AIR XTU 664

Temperature and relative humidity regulator
with time programmer C-Bus REMOTE MANAGEMENT: Can be implemented with the ACB 460 accessory
GENERALITY
3-point controls for water coil valves selectable for heating and/or cooling
– or ON-OFF for 1, 2, 3 stage electric heaters
– or ON-OFF for 1, 2-stage direct expansion coils
Progressive command 0...10V DC:
– for air mixing damper servomotors
– or for rotary recuperator
– or for steam humidifier
As an alternative to a 3-point command:
– adiabatic humidification coil ON-OFF control e
– ON-OFF command for fan/s with time program or alternatively
– ON-OFF command according to the seasonal period
Telemanagement via additional ACB 460 board
Programming with 4 operating keys and alphanumeric display
