The COOL/HEAT mode lock requires initial programming during installation. Please consult your authorized dealer
for assistance. The COOL/HEAT mode lock sets the unit forcibly to either COOL or HEAT operation. This function
is convenient when you wish to set all indoor units connected to the multi system to the same operation mode.
