8. (Step 3) Installing the energy-saving controller

The actuator can be installed on all standard heating
valves. There is no need to drain away water or fiddle
around with the heating system before doing this. First,
you need to remove the old thermostat dial:
• Turn the thermostat dial anti-
clockwise as far as it will go (A).
Release the thermal ring of the
•
thermostat (B).
• Remove the thermostat from
the valve (C).
An adapter will need to be used
in the case of certain valves.
Adapters for Danfoss valves (RA, RAV, RAVL) are inclu-
ded in the scope of delivery. For details, please refer to the
adapter overview (see 26).
The adapter must be placed on
•
the valve and turned until it is
securely seated.
In the case of the RAV adapter,
•
the extension supplied must be
attached to the valve tappet.
• The RA and RAV adapters
must, in addition, be secured
by means of the bolt and nut
supplied.
The energy-saving controller can only be installed if "InS" is
showing on the display. Following installation, the actuator
will perform an adjustment run so that it can adapt to the
valve. During this process, "AdA" will be displayed.
• Place the actuator on the valve.
Tighten the union nut.
