The SMX Net, (SMX Online for Air-Cooled A/C systems), like the SMX II, is a microprocessor-based electronic control system for use with Cruisair Direct Expansion (DX), Tempered Water (TW), and DX Air-Cooled air conditioning systems.

Unlike the SMX II control system, the SMX Net allows multiple air conditioning units to be networked together for central control. Each unit in the network has a unique ID number, allowing you to control any SMX type keypad on your boat from any other SMX keypad, just as if you were there.

SMX Net systems use the state-of-the-art SMXir keypad/display with optional remote, or the SMX Net (SMX Online for Air-Cooled systems) keypad/display which can be retrofitted in the field to replace a electromechanical rotary switch assembly. Additional SMX Net control system features include: outside temperature display, auxiliary (electric) heat control and 2-speed fan control.

Using the optional SMX Net Convenience Panel, you can put all your systems into a preprogrammed day or nighttime mode at the touch of a button. You can lock out one or more air conditioning systems to maintain optimal electrical load control. And when you leave the boat, you can put the systems into a preprogrammed dehumidification mode with a single keystroke.

Many of the SMX Net's factory settings can be changed; customizing the system to best match your personal preferences.
