Note:
When activating valve proving (e.g. on shutdown), the load on the valve
terminals is restricted. If the load is not reduced, the design lifetime is about
100,000 burner start cycles!

Caution!
Maximum permissible current load may be exceeded!
If terminal X2-02 pin 3 is used as the connection for supplying the PWM
motor, no other motor may be connected on terminal X2-01 pin 3.
