the fastening and pull the thermostat off of the valve.

2. 

 Use an appropriate adapter, if required, and push it onto 
the valve.

3. 

 Screw the connector on the valve or the adapter.

closed several times to store the end points. In some cases 
this process can take a few minutes. After successful adapta-
tion it returns to normal mode.
