• For common AHU with multiple AHU KITS, sharing with 1 room temperature sensor is possible. The room
temperature sensor sharing uses the communication of wired remote controller, so Wired remote controller
should be installed. mA temperature sensor is the same as well. (Refer to SEG 24 of installation option 05 series
on page 26.)
• If one room temperature sensor is used for multiple AHU kits, MCM-D201N should only be used.
