Operation with Advanced Microprocessor with Graphics Control

3.13.2Nonvolatile Memory

All critical information is stored in nonvolatile memory. Setpoints, setup parameters, and component run hours are kept inside the microcontroller in EEPROM. Information retained for data logging,

24 hour component run hour graphs, alarm history, and the water detection floor plan is kept in non- volatile RAM.

3.13.3DIP Switches

Equipment options are selected and enabled using DIP switches 1 to 7. These are located at the upper left of the control board and are labeled SW1. Switch 1 is at the top. These switches are factory set and should not require any user changes. The setting and function of the switches can be read from the LCD (see 3.8.4 - DIP Switches).

3.13.4Control Outputs

Active control outputs are indicated with LEDs on the lower section of the control board. Each LED is lit if the control output is active (on). Use these LEDs to assist in troubleshooting the system.
