How To Adjust As310e's Relay "setpoint"
AS310e has control relay (contacts rated 24Vac, 2amp) which can be set to open or close at any co2 level, from 0-5,000ppm.
Remove cover and locate JP1-JP5 in the upper left corner of the pcb. Move the shorting block from JP5 to JP3. The LCD will show the relay setpoint. Push the UP or DOWN button to adjust the reading. Return the jumper to JP5. Placing the shorting block over both pins of JP5 causes the relay contacts to close as co2 rises. In greenhouses, for controling addition of co2, store the shorting block over only one pin of JP5 and the relay will open as co2 rises.
