Why MAXUM vs classic Logic 5.0

Faster average travel — about 12″/sec on many sectionals (vs classic industrial packages)
Floor-level LCD setup & diagnostics — less ladder time for programming and errors
Built-in Wi-Fi / myQ Facility — remote status, cycle counts, maintenance insights
Soft start / soft stop — quieter, gentler on the door system
Dual handing — one unit covers left or right installs

Classic Logic 5.0 J /
H /
T remain strong workhorses — MAXUM is the next-gen option when speed and connected diagnostics matter.
