RELAY
For correct operation of the DDS system, conductors 1 and 2 should be connected across a set of volt free contacts as shown.
When in operation, the contacts should close when the dewpoint reaches the set point and remain closed until the moisture
content rises above the set point.
Note: The dryer has an internal moisture over-ride which has been factory set at 30 minutes. This means that the dryer will revert
to normal operation after 30 minutes regardless of the dewpoint.
