It is critical that you check the serial number of the CPAP. Respironics change the design of the switch panel during the production of the Respironics REMstar Plus (Legacy) model to the point that there are two keypad designs. The 2 Million (2,000,000) serial number is the switch over point between keypad designs. It is a very subtle difference, only with a very careful study of the control panel and shell can the difference be observed.
This is the replacement keypad with three control buttons works for the Respironics REMstar Plus Legacy CPAP with serial number > 2,000,000:
- Power On/Off
- Ramp
- Humidifier Temperature
For the REMstar Legacy Series of CPAP/BiPAP such as the REMstar Plus.
Over time the contacts on the back of the buttons can build up resistance and no longer work. Easily replace the keypad with this replacement.
