Troubleshooting Section
The S

Room Pressure Controller is designed to be trouble free. However, installation
problems or interaction with other HVAC components may cause system problems. The
S

system is easy to troubleshoot if an organized approach to evaluate the system is
taken. Troubleshooting is broken down into hardware and software problems. Hardware problems
deal with the physical installation of the device. Hardware problems include wiring problems,
incorrectly installed equipment, and add-ons or non-TSI equipment. Software problems include
control problems, configuration problems, or interaction problems with the HVAC system.
The hardware test described in this section determines that all TSI mechanical components are
functioning correctly. The hardware test requires the diagnostics menu items to be accessed. If
you are unfamiliar with the S

procedure. Troubleshooting the majority of problems is usually quick if the hardware test is
followed.
Software and hardware problems are covered in the troubleshooting chart. Pick the problem that
most closely resembles your problem and review the possible symptoms and corrective action.
Software or system performance problems can and are affected by the supply air system, exhaust
air system, or physical configuration of the room. Separating TSI system problems from the
HVAC system can sometimes be difficult. TSI recommends confirming all hardware is operating
correctly before troubleshooting software problems.
Hardware Test
Three tests need to be performed in order to determine all hardware is functioning correctly. The
test are broken down into:
•
Confirming wiring is correct.
•
Confirming physical installation is correct.
•
Verifying mechanical components.
Confirming wiring is correct
The most common problem with installed hardware equipment is incorrect wiring. This problem
usually exists on initial installation, or when modifications to the system take place. The wiring
should be very closely checked to verify it
exactly
matches the wiring diagram. The TSI cables are
all color coded to ensure proper wiring. A wiring diagram is located in Appendix C of this
manual. Wiring associated with non TSI components should be closely checked for correct
installation. If non TSI components are installed, consider disconnecting them for testing
purposes.
Confirming physical installation is correct
All of the hardware components need to be installed properly. Review the installation instructions
and verify components are installed properly at the correct location. This is easily done when the
wiring is checked.
Verifying mechanical components
Verifying all TSI components are operating correctly requires following a simple procedure. The
fastest procedure to confirm all equipment is operating is to first test the DIM, and then go into the
diagnostic menu to test each component.
NOTE
: These tests require power to the units, so if unit has no power, refer to hardware
troubleshooting chart to eliminate power problem.
