Instructions for installation and use

12. CONTROL OF HEATING CIRCUIT

Self-acting flow controller with integrated control valve and ac
tuator
For controlling the heating circuit the Akva Lux II VXe is supplied with
a self-acting flow controller with integrated control valve Danfoss
AVQM and a Danfoss AMV actuator placed in the primary return flow
line. The AMV actuator is electrically wired to the controller from
the plant.
The control valve closes on rising differential pressure and opens on
falling differential pressure to control max flow. The controller closes
when set max. flow is exceeded.
In a combination with electrical actuators AMV and ECL electronic
controllers the flow and temperature can be controlled to achieve
highest energy savings. The controller is equipped with excess pres-
sure safety valve, which protects control diaphragm for flow control
from too high differential pressure.
AMV 150
The actuator has undergone a functional test and is preset from
factory.
In the event of operating disturbances the actuator can be shut off
manually by turning the manual override knob on top of the actuator
clockwise. Please note that the knob can be "tight" to turn.
