Required Action

Shut the unit off and check wiring.

Reset Method

This error must be manually reset and requires a power reset.

H. Error Code 8 — E2 Test Failure

Error Criteria

This error occurs if internal hardware detects an E2 failure.

Required Action

Shut the unit off.

Reset Method

This error must be manually reset and requires a power reset.

I. Error Mode

When an error occurs, the red and yellow LEDs both come on steady. To determine the error, follow these steps:

1.Enter the Run mode by pushing buttons #1 and #2 for at least 3 seconds until all LEDs flash.

2.Press and release the #1 button to enter the Read mode.

3.Push the ADVANCE/MANUAL (#2) button to advance to item number 20, “1st Most Recent Error.” Determine the error(s) by reading the values in items 20-24 and referring to the error codes described above.

4.Fix the error(s).

5.Press buttons 1 and 2 to exit read mode. Enter Setup mode by pressing button #1 for at least 3 seconds until all the LEDs flash.

6.Push button #2 to advance to item number 20.

7.To reset the error code while the green DS4 LEDS is ON, press the READ/ADJUST (#1) button once. This resets the error mode and erases all repaired error codes.

NOTE: Cycling power to the board will also erase the repaired error codes.

J. RAM Test Failure

Error Criteria

If internal hardware detects a RAM failure, this alarm will be displayed by alternately flashing DS1+DS3 and DS2+DS4.

Required Action

Shut the unit off.

Reset Method

This error must be manually reset and requires a power reset.

K. ROM Test Failure

Error Criteria

If internal hardware detects a ROM failure, the alarm is dis- played by alternately flashing DS1+DS2 and DS3+DS4.

Required Action

Shut the unit off.

Reset Method

This error must be manually reset and requires a power reset.

L. Unit Always In Unoccupied Mode

A jumper wire is factory-installed to force the unit into occu- pied configuration whenever G or Y1 are closed. Without the jumper wire, the unit will always be in unoccupied mode. Check the wire. An occupied/unoccupied switch may be installed in place of the jumper. Check the wiring and setting of the switch.
