The CS1 current switch is an alternative to using an air pressure differential switch and can work with one fan. It can work in conjunction with the Merlin 1500GD, the Merlin 2000GD or the Merlin 1200s panels.

A two-core volt free connection from the CS1 to the Merlin panel allows the gas valve to open when current is being monitored
