a line through it and the dryer will operate normally.
When the remote switch is closed, a 24V DC signal is applied to the digital

The icon background will change from grey to blue and the line will
disappear to indicate that the dryer has been remotely stopped.

the controller will re-start the drying cycle on a fully regenerated desiccant
bed.
