•
the display and installation (Step 3) can commence.

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).
The support ring supplied helps
to fasten the energy-saving con-
troller in a more stable position if
the relevant valve connections are only small.
• Attach the support ring to the
valve connection (D). If the valve
connection is too large to attach
the support ring to it, the stability
is already sufficient and the sup-
port ring is not required.
