Setting up two controllers
Up to two controllers can be connected to the HA and HB terminals on
the indoor unit as shown.
From the factory all controllers are supplied with SW1
dip switch setting 1 OFF and dip switch setting 2
OFF. When configuring a second controller, two dip
switches on the rear of the second controller (SW1
location) must change to the ON position as shown.
Dip switch settings for the primary controller must
remain unchanged.
If two controllers are installed both are equal and
reflect the same information, and operational changes can be done on
either controller. Wi-Fi control may be setup on one of the controllers
only. There is no polarity between HA and HB.
