The PM2 current monitor is an alternative to using air pressure differential switches and can work with up to two fans. It can work in conjunction with the Merlin 1500GD or Merlin 2000GD panels.

A 12volt supply from the Merlin 1500GD or 2000GD panel powers the PM2 current monitor. A two-core volt free connection from the PM2 to the Merlin panel allows the gas valve to open when current is being monitored. There is a potentiometer fitted to the PM2 for both the supply and extract fan. This allows fine tuning of the PM2 when installing the system.
