All these controls perform non-volatile lock-outs, condition
from which a restart of the system is only possible by
means of the control manual reset.
This range of controls is suitable to equip burners for
domestic and industrial heating. The VM41 control is
suitable for single flame applications, while the VM42
control is suitable for dual flame applications.

flame (ionization);
− two independent safety contacts for the gas valve
control;
− electrical service life at max.declared loading >250.000
− inbuilt manual reset;
− easy to install and wire;
− interchangeable with the relevant mechanical controls
as regards operation and dimensions;
