APPLICATION NOTE
A350P Proportional Temperature Control
of Johnson Controls® VA-7152 and VA-8052 Valve Actuators
A350P
IMPORTANT: Use the A350P temperature control
only as an operating control. Where failure or
malfunction of the A350P control could lead to
personal injury or property damage to the controlled
equipment or other property, additional precautions
must be designed into the control system.
Incorporate and maintain other devices such as
supervisory or alarm systems or safety or limit

Application
The A350P proportional temperature control can
control VA-7152 and VA-8052 series valve actuators.
VA-8052_COM_TRANS
Applications can use a common 24 VAC power supply L1
