Turn on DIP switch No.5 of the master unit PCB
Use '▶' and '◀' button to mark "Func" in the 7 seg-
ment, and press ' ' button.

! CAUTION
• Request the function settings to the installation specialist during
the outside unit installation.
• When the function is not used, set it to OFF.
• Before changing the mode, make sure to check if the antifreeze
is added to the heat source water with appropriate ratio.
(If it is set to geothermal mode with inappropriate addition of an-
tifreeze or without antifreeze, there is a risk of product damage,
and we will not be responsible for such damage of the product.)
• When you add antifreeze, there may be increase of pressure dif-
ference in the heat source water system and product perform-
ance degradation.
• If it is in geothermal mode, add antifreeze according to the tem-
perature condition of at least -10°c.
(If the added amount is of -10°C or more, it may cause freeze
and burst of the heat source water.)
