Function
The RVAZ2-24 is an electromechanical actuator, intended for use in
applications such as heating, cooling, ventilation, chilled beams, fan-coils
and radiators. The actuator is very versatile, suitable for a wide range of
valves.

Installation
Start-up sequence
During operation the actuator will self-adjust according to stroke length
of the valve.
N N o o t t e e ! ! The actuator will not work properly if no valve is installed.
Mounting
Upside down installation is allowed, along with the standard horizontal
and vertical installation.
Fix the actuator to the valve using the connection nut, manual power is
sufficient.
C C a a u u t t i i o o n n ! ! Do not use any tools as they can damage the actuator bracket.
Make sure the actuator stem is completely retracted before mounting it
on the valve.

Wiring
The actuator has a halogen free connection cable fixed to the actuator.
Connect the supply voltage and control signal. If the actuator and
controller share a transformer, it is very important to keep the phase
separate from the zero, so the same pole is used as zero for both
controller and actuator, since this is the reference for the control signal.
