DG8000,controlli,Controller for Terminal Units

APPLICATION AND USE
DG8000 controllers are used for 3-speed fan-coils, 2 or 4-pipe,
with On/Off valve (DG8001) and floating proportional valve
(DG8000), especially suitable for hotel rooms, hospitals and offices.
The user interface allows enabling/disabling control, setting the
3 fan speeds, changing the set-point and displaying the room
temperature.
OPERATION
DG8000 is composed of a controller, an user interface
designed for mounting into 3-unit Bticino housing and a return
sensor.
The controller can operate in Stand-alone or under ModBus
supervision. In the first case the controller operates with factoryset
parameters. In the second one it operates with the parameters
defined during the ModBus Supervision communication.

AXCU22/WMB,controlli,Electronic Fan-coil Controllers

AXCU22/WMB is an electronic fan-coil controller designed to control valves with on-off actuators, electrical heaters if
present and the three fan speeds. Once the unit has been set correctly, it controls the following fan coil units:

  • 2 pipes
  • 2 pipes with electric heaters
  • 4 pipes
  • independent wall thermostat
  • ceiling-mounted installations
  • floor-mounted fan coil installations

In all cases, automatic control of the three fan speeds based on the offset between the ambient temperature and the
set point.
Moreover AXCU22/WMB allows network connectivity: through serial TTL connection in fact it is possible to get an interface with RS485 network using the proper converter module TTL-RS 485 (AXCU/BA() directly on a PC or PLC. The

BV..P,controlli,PICVs – Pressure Independent Control Valves with Flanged Connections

BV..P,controlli,PICVs – Pressure Independent Control Valves with Flanged Connections

Pressure Independent Control Valve with diaphragm structure and
adjustable flow rate combines the advantages of dynamic balancing
valve and two-way control valve. Maximum flow rate can flexibly
be set which shows obvious advantages in changeable flow system
when load fluctuates greatly. They are used to solve the problem of
hydraulic balancing in heating and air conditioning systems. It has a
strong anti-jamming ability and a high degree of control accuracy,
which makes it work well in the frequent fluctuating flow system.
BV..P flanged valves can be coupled with MVE Controlli actuators
(no MVExxxS/SR short yoke).
