3.3.1 Selecting communication wire for AHU-KIT and wired controller
Wire type
Total length of
communication wire
between indoor unit and
wired controller (m/ft.)
Wire diameter (AWG)
Remark
Light/Ordinary polyvinyl
chloride sheathed cord.
(60227 IEC 52/60227
IEC 53)
L≤250(850)
2×18~2×16
1. Total length of
communication cable can't
exceed 250m (850ft.).
2. The cord shall be Circular
cord (the cores shall be twisted
together).
3. If unit is installed in places
with intense magnetic field or
strong interference, it is
necessary to use shielded
wire.
Connection between AHU-KIT and wired controller is shown as follows
：
(1) When one AHU-KIT is connected to one AHU, you can adopt the connection ways of one
wired controller to one AHU-KIT or one wired controller to several AHU-KITs (group
control, n≤16).
(2) When several AHU-KITs are in parallel connection with one AHU, you can only adopt the
way of one wired controller to several AHU-
KITs (group control, n≤2).
