Display Qht Marine Cruisair Dometic, 722200200, 722200210

Display Qht Marine White / Gray

Qht Keypad/Display for Cruisair DX and Tempered Water – Vimar Idea Bezel, and vimar eikon bezel

For Operation With the Q-Logic Microprocessor Control System

The Q-Logic microprocessor control system works with Cruisair direct expansion evaporators and tempered water air handlers. Q-Logic consists of a power/logic circuit board installed in the electrical box of the evaporator or air handler, and is controlled by a Qht or Q3 keypad/display.

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.

An optional CAN-bus network adapter is available for new Q-Logic systems and as a retrofit for existing installations to provide ship-wide network monitoring and controlling of multiple DX systems or air handlers.

The Qht also operates the auxiliary heat. If the optional water-temperature sensor is installed, Q-Logic provides an automatic change-over function from cooling to heating.

A dehumidification mode operates the system on a timed basis so the boat stays ventilated and dry even when no one is aboard (optional electric heat package recommended).
