*NOTE: P11, RP11, & RP22 are digital outputs (not physical devices) wired in parallel with outputs P1, RP1, & RP2 respectively.
These outputs are only used if airless contactors are installed. If installed, test by activating both outputs (P1 and P11), (RP1 &
RP11), (RP2 & RP22) at the same time and verifying the corresponding feedback signal.
