TESTING THE CONTROL
The control has a built-in test routine that is used to test the main
control functions. The control continually monitors the sensors and
displays an error message whenever a fault is found. See the following
pages for a list of the control’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, if a demand from the system is present, the test sequence may be paused by pressing the Test button. 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.
STEP 1:
The primary pump is turned on and remains on for the entire test routine.
STEP 2:
If the Alarm / C.A. DIP switch is set to Alarm, the Alarm contact is turned on for 10
seconds and then shuts off. If the Alarm / C.A. DIP switch is set to C.A., the Combustion
Air Damper contact is turned on and remains on for the entire test routine.
STEP 3:
For each boiler that is set to Auto, the following test sequence is used. If the mode
indicates that a boiler pump is used, the boiler pump is turned on and remains on. Next,
the first stage of the boiler is turned on and remains on. If a second stage is present, the
second stage is turned on and remains on. If a third stage is present, the third stage is
turned on and remains on. If a fourth stage is present, the fourth stage is turned on. After
ten seconds, all stages and the boiler pump are turned off.
This step is repeated for each additional boiler that is set to Auto.
STEP 4:
All contacts are turned off.
