Built-in test procedure
The AEC-2 has a built in test procedure. The test should be performed after the control has been installed
and may be used at any time to check the operation of the control. The test procedure tests the circuitry in
the control and each stage individually. Follow the instructions below to step through the test procedure.
If an alert system is connected, be aware that it is normal for the alert to be activated during
most of the test procedure.
In order to start the test procedure, power to the AEC-2 must be
off. Then, while holding the UP and DOWN buttons in, turn on
the power. The AEC-2 will start up in the test mode.
Input test
1) Press the PROG button once. The AEC-2 will display a number.
This number should be between 100.0 and 125.0.
Press the PROG button again and the AEC-2 will display the
temperature. If the temperature displayed is not correct, check if the
sensor is installed properly.
Memory test
2) Press the STORE button. The AEC-2 will display PASS if the
factory programs are in memory. It will display FAIL if the programs
in memory have been changed in any way from the factory settings.
See Reloading the Factory Programs under the Getting To Know The
AEC-2 section in this user's guide to reload the factory programs.
