13. CONTROL OF HEATING CIRCUIT

Self-acting ow controller with integrated control valve and ac
tuator Akva Lux II VXi & VXi Solo H
For controlling the heating circuit the Akva Lux II VXi and VXi Solo H
are supplied with a self-acting ow controller with integrated con-
trol valve Danfoss AVQM and a Danfoss AMV actuator placed in the
primary return ow line. The AMV actuator is electrically wired to the
controller from the plant.
The control valve closes on rising di erential pressure and opens on
falling di erential pressure to control max ow. The controller closes
when set max. ow is exceeded.
In a combination with electrical actuators AMV and ECL electronic
controllers the ow 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 ow control
from too high di erential 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 o
manually by turning the manual override knob on top of the actuator
clockwise. Please note that the knob can be "tight" to turn.
AMV 13
The actuator has undergone a functional test and is preset from
factory.
Depending on the selected setting of the safety function, the AMV 13
valve is fully opened or closed when the voltage supply is switched
o .
