7. Adapter run
Once the batteries have been inserted, the motor reverses;
meanwhile, "InS" and the activity symbol (

As soon as "InS" is displayed without the activity symbol
(
), the electronic radiator thermostat can be mounted.
This is followed by an adapter run ("AdA") to adapt the ther-
mostat to the valve.
• Attach the radiator thermostat to the valve.
• Tighten the union nut.
• Press the boost button when "InS" is displayed.
