European Burner Controls
European Standards (CE, EN, etc.)
Some European burner controls have low voltage limit and/or VPS terminals, which differs from the line voltage load terminals.
The wiring diagram below addresses wiring of such controls with the SV2 Series valves.
Certain European burner controls do not have separate interlock circuits. The SV2 Series valves require that the ILKIN terminal
be tied to the burner management control is some manner and not simply jumpered to L1 power.
Burner controls with independently switched line and neutral voltages will not work as is with the SV2 Series valves and require
extra components plus wiring to make them work effectively with the SV2 Series valves.
As well, per European standards, the burner management control used shall have two line voltage switching elements in series
that switch power to the valve coils. If the burner control does not two switching elements in series, the following alternatives
may be used in the European Union, per KIWA.
For systems using VPS, MV1 and MV2 must be powered separately.
