CO Sensor Input (Optional)
If a CO Sensor is wired to the Electric Control package and the CO sensor is triggered, all exhaust fans
will be turned ON and will ramp up to their high speed. All supply fans will be turned OFF, the gas valve
will be shut off, and the shunt trip will be ON. This option is only accessible through terminal IO1.
Terminal IO1 should be energized by closing a dry contact placed between terminals H1 and IO1. CO
sensor should be enabled; otherwise, the IO1 terminal will function as BMS input. Factory Default Setting
is OFF.

This option can only be enabled if CORE Hood is disabled. If this option is enabled, all the faults
occurring on a connected PCUCORE system will be displayed on the HMI. A cat5 cable will be needed
to connect the PCUCORE to the slave side of the network,typically J3. Factory Default Setting is OFF.
