CO2 monitor - low battery alarm

[Duplex]

Has anyone had an issue with the CO2 monitor alarm sounding as the ZAMP charge controller is starting as the sun is rising?  At least once a week while hooked up to shore power, our CO2 alarm sounds and flashes the Low battery code.  The ZAMP rep says "if the CO2 monitor is not isolated from the solar system, this could mean a short or crosswire situation."  Any help would be appreciated, we would rather not be awaken by flashing light and an alarm.  This usually happens while the ZAMP controller is flashing as the sun is coming up. Does your ZAMP controller flash as it is starting each morning?

 

Thanks,

John

What the Zamp representative is says is that the CO monitor should be hooked directly to power (like a positive buss bar) to isolate it from all other systems.
