Troubleshooting Section 

 
The PresSura Room Pressure Monitor is designed to be trouble free. However, 
installation problems or interaction with other HVAC components may cause system 
problems. The PresSura 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 configuration problems and 
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 PresSura menus, see 

Software 

Programming

 for keystroke 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 hospital 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 tests 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 B 

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.
