General Wiring Instructions
WARNING The wiring technician must be trained and experienced with
electronic circuits. Disconnect power supply before attempting any
wiring connections or changes. Make all connections in accordance with
wiring diagrams and follow all applicable local and national codes.
Provide disconnect and overload protection as required. Use copper,
twisted pair, conductors only. If using electrical conduit, the attachment
to the actuator must be made with flexible conduit.
Always read the controller manufacturer's installation literature
carefully before making any connections. Follow all instructions in this
literature. If you have any questions, contact the controller manufacturer
and/or Belimo.
Transformer(s)
Belimo actuators require a 24 VAC class 2 transformer and draws a
maximum of 10 VA per actuator. The actuator enclosure cannot be opened
in the field, there are no parts or components to be replaced or repaired.
800-543-9038 USA
– EMC directive: 89/336/EEC
– Software class A: Mode of operation type 1
– Low voltage directive: 73/23/EEC
CAUTION It is good practice to power electronic or digital controllers
from a separate power transformer than that used for actuators or other
end devices. The power supply design in our actuators and other end
devices use half wave rectification. Some controllers use full wave
rectification. When these two different types of power supplies are
connected to the same power transformer and the DC commons are
connected together, a short circuit is created across one of the diodes in
the full wave power supply, damaging the controller. Only use a single
power transformer to power the controller and actuator if you know the
controller power supply uses half wave rectification.

WARNING! Do Not Pipe in this manner!
Note Valve Porting!
The A-port must be piped to the coil! Not the B-port!
Flow is not possible from A to B. If AB-port is not piped as
the common port, the valve must be re-piped. It is good
practice to install a balancing­valve in the bypass line. These
valves are intended for closed loop systems. Do not install
in an open loop system or in an application that is open to
atmospheric pressure.
Operation/Installation – Correct Piping
2-way valves should be installed with the disc upstream. If installed with disc downstream, flow curve will be deeper. If installed “backwards” it is NOT necessary to
remove and change. No damage or control problems will occur.
3-way valves must be piped correctly. They can be mixing or diverting. Mixing is the preferred piping arrangement.
The BELIMO Characterized Control Valve is a CONTROL valve, not a manual valve adapted for actuation. The control port is the A-port. It is similar to the globe valve in that
the middle port is the B or bypass port. The common port AB is on the main opposite the A-port. These diagrams are for typical applications only. Consult engineering
specification and drawings for particular circumstances.
Reduced B-Port Flow
Note: The B-port flow of the 3-way CCV is lower than that of the A-port. In most applications this is beneficial since the reduced flow compensates for the inexistent
pressure drop across the coil in the bypass mode. Therefore, proper sizing is important to avoid flow noise in particular when the system is designed with constant
speed pumps. Please refer to our valve sizing and selection guidelines.
The flow velocity in the pipe upstream and downstream of the valve should be considered as well. The typical HVAC design maximum flow is 4 to 8 ft/s to avoid noise
issues.
Also, the pipe reduction factor must be considered and can be found on pages 3 and 4. Pipe reducers decrease the Cv value of a valve and consequently increase the
pressure drop across the valve, a situation that could lead to noise or a lower than designed flow.
