4.3.1.1
Saving and Restoring Setpoint Parameters
Upon initial start-up the A/C system operates using the
setpoints programmed by the factory (primary setpoints)
as the operating setpoints. As described in Section
4.3.1,
the customer may enter new operating parameters in the
Control menu anytime and the system will then operate
accordingly. The customer may store the new setpoints
in the Service menu if it is intended to save them. Once
stored, the Customer setpoints now become the operating
setpoints. The primary setpoints entered by the factory still
remain stored in the controllers' memory as the Factory
setpoints.
At any time, setpoints for the system may be re-adjusted
to any value and the system will operate accordingly. If
it becomes necessary however, the customer may enter
the Service menu and restore the setpoints to the stored
Customer operating setpoint values. The original Factory
(primary) setpoint values may also be restored from the
Service menu. Whichever setpoints are restored (Factory
or Customer), become the current operating setpoints.
