Microprocessor Control

Equipment Options Switches

Equipment options are selected and enabled using DIP switches 1 through 7. These are located on the control board near TB1. These switches are factory-set and should not require any user changes. The setting and function of the switches can be individually read on the LCD display.

NOTE

In order to update the dip switch settings, power must be cycled off, then on, from the unit disconnect switch.

6.17Run Diagnostics (Available On Rev 1.001.0 and higher)

By selecting Run Diagnostics, maintenance personnel can check system inputs, outputs and conduct a test of the microcontroller circuit board from the wall box control. A review of the system inputs and the microcontroller test can be done without interrupting normal operation.

Show Inputs

With the unit on and the fan running, the input states may be displayed for the following devices:

•High Water Alarm: Normally off unless High Water Alarm is active.

•High Head Pressure Alarm: Normally off unless High head Pressure alarm is active.

•Custom alarm #1: Normally off unless this special customer selectable alarm is active.

•Custom alarm #2: Normally off unless this special customer selectable alarm is active.

•Power: Normally on unless unit is turned off through the wall box or any of the following optional

devices: High Temperature Sensor, Smoke Sensor, High Water Alarm or Remote Shutdown
