SIMULTANEOUS OPERATING BY ONE REMOTE HAND SET SIGNAL.
COMPRESSOR DELAY function may be established at the time of installation of your Air V. If you have one air
conditioner, you need not use these functions. However, if your vehicle has more than one cooling system, depend-
ing on the manufacturing installation, you must use COMPRESSOR DELAY function to avoid simultaneous operating
the units which may cause the damage of power system of the vehicle.
COMPRESSOR DELAY FUNCTION
COMPRESSOR DELAY function is defined and preset by your manufacturer. (NO or 3SEC) The default is NO. To change
NO to 3SEC in your air conditioning unit, you must change the COMPRESSOR DELAY function switch of main printed
circuit board in the ceiling assembly frame. With a sharp object, you can change the COMPRESSOR DELAY function
control. As illustrated below. You must apply the above procedures to only one of two units. The unit applied this
function starts approximately 3 seconds later than the normal unit does, so the simultaneous start of the units is
impossible in general.
