※1 If the ambient temp is –10˚C or lower, the function check of the solenoid valve cannot be preformed
correctly, short circuit the terminals 121 and 102 on the terminal board, and check the operation of
the solenoid valve.
※2 If the difference between ambient temperature and return air temperature is 15˚C or higher, these
steps will be skipped.
Air cooled
operation
–10˚C < Ambient temperature ≦ 43˚C
When the ambient temperature is above 43˚C or below –10˚C, the correct judgment
may not be possible.
–10˚C ≦ Ambient temperature ≦ 43˚C
When the ambient temperature is above 43˚C or below -10˚C, the following alarm will be indicated.
J501: Out of ambient temperature specified conditon.
