Testing the Control

The Boiler Control 262 has a built in test routine which is used to test the main control functions.

The 262 continually monitors the sensors and displays an error message whenever a fault is

found. See the following pages for a list of the 262’s error messages and possible causes.

When the

Test

button is pressed, the

Test

light is turned on. The individual outputs and relays

are tested in the following test sequence.

TEST SEQUENCE

Each step in the test sequence lasts 10 seconds.

During the test routine, the test sequence is paused by pressing the

Test

button. While paused, the control displays the testing step as

well as the word PAUS. If the

Test

button is not pressed again for 5 minutes while the test sequence is paused, the control exits the entire

test routine. If the test sequence is paused, the

Test

button can be pressed again to advance to the next step. This can also be used

to rapidly advance through the test sequence. To reach the desired step, repeatedly press and release the

Test

button until the

appropriate device and segment in the display turn on.
