1 .1 .1 TC 1V with valVario controls

Mains voltage = control voltage
V1: quick or slow opening valve with start rate.
V2: pressure regulator with solenoid valve.
Tightness control TC 1V checks gas solenoid valves V1
and V2 and the pipe between the valves for tightness.
If both valves are tight, the TC forwards the OK enable
signal to the automatic burner control unit GFA. This
opens valves V1 and V2 simultaneously. The burner
starts.
