Pactrol CSM.

CSM controls are designed to provide ignition of a gas burner under remote, manual control, while providing automatic shutdown and lockout in the event of any subsequent flame failure.

A compact semi-automatic control for all types of gas burner. The control has push-buttons for START and STOP functions, and a ''flame-on'' indicator lamp. Flame supervision is by flame-rectification, with the option of ultra-violet sensing by the addition of a special UV head.

The control is intended for applications where the burners are not left running unattended for long periods. It is not suitable for permanent pilot systems.
