APPENDIX 2
FACTORY RUN TEST PROCEDURE
GENERAL
Each unit undergoes a fi nal QA check before the unit
is shipped from the factory. This fi nal check includes
a complete operational test that verifi es the operation
of all of the systems and installed options on the unit.
The Run Test is built into and performed by the Unit
Controller. The Run Test can also be used in the fi eld
to verify operation at start up.
The unit will arrive in the fi eld with all the ordered
options already confi gured. As part of start up you may
need to change set points and turn features ON or OFF
based on the desires of the customer. Once confi gured
the Run Test mode can be used to verify operation.
RUN TEST INITIATION
The Run Test sequence is initiated by performing the
following:
•
Press the “Program” button one time. This
places the Unit Controller in the program mode.
The two-digit display will show the fi rst param-
eter, 01, which is the Run Test parameter. The
four-digit display will show a 0. The 0 indicates
that the Run Test is off.
•
Press the “Alarm/Advance” button one time.
This places the Unit Controller in the change
mode.
•
Press the “Address/Down” key one time to
change the 0 to a 1.
•
Press the “Program” button one more time to
initiate the Run Test mode.
RUN TEST SEQUENCE
The run test sequence is as follows:
•
If the supply fan is not on at the start of the test
it will be energized. On a VAV unit the fan will
operate at the programmed minimum speed.
•
The Unit Controller will energize the binary
output for compressor #1 and condenser fan
#1. 15 seconds later the Unit Controller will
energize the output for the compressor #2. 15
seconds later the Unit Controller will ener-
gize the binary output for compressor #3 and
condenser fan #3. 15 seconds later the Unit
Controller will energize the binary output for
compressor #4.
•
The Unit Controller will operate each compres-
sor for 3 minutes. This results in the compres-
sors turning off in reverse order.
•
There will be a 2-minute delay between when
the last compressor turns off and the start of the
heating sequence.
•
The Unit Controller will energize the binary
output for each of the staged heat sections in
15-second increments.
•
The Unit Controller will operate each staged
heat sections for 3 minutes. This results in
the staged heat sections turning off in reverse
order.
•
If the unit is equipped with hydronic heat the
Unit Controller will send a 10 VDC, direct
acting, 2 VDC, reverse acting, signal to the
hydronic valve for 2 minutes.
