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

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