PROGRAMMING - STEP 2
TEST SEQUENCE
The SYSTEMpro 311 has a built-in test routine which is used
to test the main control functions. The control monitors the
sensors and displays an error message whenever a fault is
found. See Appendix IV (page 98) for a list of the
SYSTEMpro's error messages and possible causes. When the
test button is pressed, the test light is turned on. The outputs
and relays are tested in the following 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 abbreviation 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
Step 1
• If FLOT is selected in MIXING item, mixing valve is run fully
open
• If VAR is selected in MIXING item, injection pump is ramped
up
over 10 seconds to 100%
Step 2
• If FLOT is selected in MIXING item, mixing valve is run fully
closed
• If VAR is selected in MIXING item, injection pump is ramped
down
over 10 seconds
Step 3
• The mixing system pump (P1) is turned on for 10 seconds
and then shuts off
NOTE: The control can only be paused
in step 3 if there is a mixing demand.
Step 4

and then shuts off
NOTE:
The control can only be paused
in Step 4 if there is a boiler demand.
