Cruisair Air Conditioning Controls

Cruisair Cabin Controls- SMX II CONTROL SYSTEM

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.

It offers all of the standard operational and safety features required for most A/C systems and more. SMX II systems use the new Euro-styled SMXht Keypad/Display, or the SMXir keypad/display with optional remote, or the SMX II keypad/display which can be retrofitted in the field to replace a electromechanical rotary switch assembly.

For normal operation, it is only necessary to turn the system on and select the desired setpoint. You can select cooling only, heating only, or automatic changeover between cooling and heating. Fan speed is automatically controlled or can be manually set.

The dehumidification mode can be used to operate the system on a timed basis so that area(s) stay ventilated and dry, even when no one is aboard.

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