Hi Terrie,
just be sure all dip switch settings are correct before commencing with initial start up of the system(s).
Once all is confirmed the system(s) should operate satisfactory.
BTW there is a nice test function facility on the pcb of the outdoor unit which will save you going around and switching on all the remote controllers.If my memory serves me right the setting for test is on dip switch 4- 1 on (cool test) & both 1 & 2 on for heat test.
Happy commissioning

regards
Jase
