Optional High Limit Contact Relay
The high CO2 limit relay option provides a dry (i.e.
unpowered) contact closure that activates when the detected
concentration rises above the high CO
2
limit. The high limit
is adjustable from 0 to 5000 ppm.
Setting High Limit Contact Polarity
The polarity of the high limit contact is set with jumper JP5
as shown in the table below.
