Note:
When valve proving is activated (e.g. on shutdown), the load on the valve's
terminals (according to chapter Technical data/Terminal rating Outputs) is
restricted.

Power factor
If the terminal load (according to chapter Technical data/Terminal rating
Outputs) is not reduced (max. rated current 2 A, cos >0.4), the design
lifetime will be reached after about 100,000 burner startup cycles!
