Cannot change P_ settings on the LME7 controller with Staged Gas Heat

Content in the image below.

When the Siemens LME7 controller in commissioning mode there is a signal priority:

Highest priority

1. Voltage Signals into X5-03 pins 2 & 3 – Used for Staged MHTD burners
2. Commissioning mode
3. Analog Signal into X65 – Used for modulating MHTD burners 

Lowest priority

Since the Staged Heat inputs at X5-03 pins 2 and 3 have a higher priority then Commissioning mode (setting P0, P1 and P2 at the LME7), if it sees voltage at these pins, it will not allow you to make changes to the motor rpms through the onboard display. 

Solution:

1. Power unit down.
2. Temporarily Remove "Relay A".
3. Power unit back up and give the unit a call for heat using Manual Override Mode. 
4. You can now adjust P0, P1, P2 setting from LME7 per instructions in the IOM (RTSVX072-EN)
5. Once settings are adjusted, power unit back down and reinstall "Relay A".
