NOTICE
① If the AHU-KIT adapter is installed in the position with strong electromagnetic interference,
the voltage signal may be impacted, which should be shielded to ensure the accuracy of
input voltage signal.
② When the AHU-KIT detects that the corresponding set temperature of voltage is "default
value":
If the unit is under cooling mode, the default set temperature is 26+ (T
(T – 60.8) °F].
lowest
If the unit is under heating mode, the default set temperature is 20+ (T
(T – 60.8) °F].
lowest
If the unit is under air supply mode, the default set temperature is 26+ (T
(T – 60.8) °F].

③ Input voltage should not be over 10V, otherwise it may damage the controller.
④ When set to the fresh air control function, the final set temperature needs to be adjusted
according to " T
