Communicating Furnace
For installation of a non-communicating indoor 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 use of an Communicating Interface Control Field
Kit(S1-33102953000).
Do Not Use a traditional humidistat to control humidifier operation. If a humidifier is installed, the
Touch Screen Communicating Control will operate humidifier.
