The Cruisair Q-Logic Control System is designed for use with both direct expansion evaporators and tempered water air handlers. This dual microprocessor-based control consists of a power/logic circuit board in the system’s electrical box that operates with Qht and Q3 control/displays.

An optional CAN-bus network adapter is available for new Q-Logic systems and as a retrofit for existing installations. Supporting both the Qht and the Q3 controls, this adapter provides ship-wide network monitoring and controlling of multiple DX systems or air handlers. The CAN-bus adapter adheres to CAN-bus Standard 2.0B and is fully ISO compliant. It is available in two CAN-bus communication protocols to support connection to several popular helm and cabin touchscreen control systems.

The Qht control/display is European in style and accommodates an assortment of decorative bezels — including a new model sized to fit the popular Vimar Eikon bezel. The Qht display features raised buttons for easy access and control and an attractive blue backlit LCD.
