•The Pump On LED (A) remains on during this time.

•The Pump On (C) icon displays.

If the Pump On sequence has been programmed to end by a pressure switch:

•The GLC 4400 pump output relay activates (J7-3) and will stay on until a switch closure is received (J6-3) (see Setup Menus, Pump On, page 19).

•The Pump On LED (A) remains on during this time.
