The VA-703x electrothermic actuator provides a two position (open/closed) control in HVAC applications. Its compact design makes it suitable for installation in confined spaces such as fan coil applications, and it is designed for field mounting onto VG6000 series terminal unit valves via an M30 x 1.5 threaded nut without tools.

Wiring instructions
WARNING
When servicing make sure that:
• the electric supply to the actuator is switched
off to avoid possible damage to the
equipment, personal injury or shock.
• you do not touch or attempt to connect
or disconnect wires when electric power is on.
• Do not open or repair, contact the nearest
Johnson Controls Commercial System
wholesaler. Figure 6: Wiring Diagram VA-7035-2xNO
When wiring the actuator, please follow the Dimensions in mm
instructions below: 38 50
• Make sure that the line power supply
is in accordance with the power supply
specified on the actuator.
• All wiring should conform to local codes 51
and must be carried out by authorised personnel
only. 2m
