The Merlin power monitor is a method used for interlocking a kitchens gas supply with the ventilation system. As an alternative to pressure differential switches the PM2+ is designed to monitor the current going to a ventilation fan. When the fan is turned on the PM2+ monitors the electrical current going to the fan motor using a unique built in current monitor which displays the exact fan current, in order to interlock with the ventilation with precision accuracy. When there is sufficient current going to the fan monitor the PM2+ sends a signal back to the Merlin system indicating the fan is running. Gas can now be introduced into the kitchen.
The Merlin PM2+ carries a 3 Year AGS warranty and is fully supported by our technical team.
