Intelligent Appliance Control
Zone 1
CO GAS INSIDE THE SUPPLY DUCT
A faulty furnace can produce low to dangerous levels of CO which can be distributed to everyone in the home through the ventilation system.
CO/PRO® monitors for CO gas in the supply duct and TURNS THE FURNACE OFF when 25 ppm of CO is detected.

When CO levels drop to 15 ppm or less, power is reapplied!
Zone 2
ESCAPED
EXHAUST GAS IN
THE AMBIENT AIR
Exhaust systems can become clogged by animals and vent joints can crack, forcing low to dangerous levels of CO into the home's ambient air.
CO/PRO® monitors for CO in the ambient air from the exhaust systems and
TURNS THE FURNACE AND WATER HEATER OFF
when 25 ppm of CO is detected.

"This unit provides way more protection to homeowners and reduces liability for contractors", said Contractor Judge #1
"The multiple ways it monitors is different that standard CO monitors", said Contractor Judge #2
"I like that this is a low-level detector, as most on the market don't alarm to over 40 ppm, and this starts below 25 ppm", said Contractor Judge #3
