Pressure Sensor Cleaning
Accumulations of dust or dirt can be removed with a dry soft-bristled brush (such as an artist's
brush). If necessary, water, alcohol, acetone, or trichlorethane may be used as a solvent to
remove other contaminants.
Use extreme care when cleaning the velocity sensors. The ceramic sensor may break if
excessive pressure is applied, if sensor is scraped to remove contaminants, or if the cleaning
apparatus abruptly impacts the sensor.
If you are using a liquid to clean the sensor, turn off power to the RPM10 /
RPM20 PresSura Monitor.
Do not use compressed air to clean the velocity sensors.
Do not attempt to scrape contaminants from the velocity sensors. The velocity
sensors are quite durable; however, scraping may cause mechanical damage
and possibly break the sensor. Mechanical damage due to scraping voids the
pressure sensor warranty.

Troubleshooting Section
The Model RPM10 and RPM20 Room Pressure Monitors are designed to be trouble free.
However, installation problems or interaction with other HVAC components may cause system
problems. The system is easy to troubleshoot if an organized approach to evaluate the system is
taken. Troubleshooting is broken down into hardware (mechanical) 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 controller menus, see
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
