Be sure to set these to OFF (When set to OFF, the
unit cannot communicate with the air conditioner).
There is a switch between TC1 and 2 input on the

When there is a problem while the unit is running,
it will output a relay ON signal.
When the Auto Restart function on the air condi-
tioner itself is set to ON, be sure to set these to
OFF.
