Jumpers listed here are required and if set incorrectly will flag an error upon installation. While the
other jumpers can be set from the Touch Screen Communicating Control, it is good practice to ini-
tially set all jumpers at the respective control. This will avoid any confusion that may occur with
future service at the units.
For installation of a non-communicating outdoor unit with the Touch Screen Communicating Con-
trol, the installer should reference the indoor and outdoor unit installation instructions. If informa-
tion is not provided, there may be a need for a Communicating Interface Control Field Kit (S1-
33102953000).
