Cruisair Controls & Boards
For precise control and monitoring of cabin temperature and humidity levels, Mid-Atlantic Marine Technology offers a number of modern, wall-mountable Cruisair controls. From electromechanical to microprocessor platforms, we have the right control for your vessel.
Qht Price: $189.95 (Includes Bezel)
(Black or White)
New! Q-Logic Controls: The Qht keypad/display is an elegant, panel-mount design that works with the Q-Logic Control System and operates Cruisair Direct Expansion (DX) and Tempered Water (TW) air conditioning systems. It offers all of the standard operational and safety features required for marine A/C systems, and includes some exciting new features and conveniences. Optional CAN-bus support puts the air conditioning system onto the ship's network.
- The Qht can replace SMXII and SMXht displays, and has the exact same size and appearance. The Qht supports both Vimar® Idea and Gewiss® Playbus Euro-styled bezels in a wide variety colors.
- Inside Temperature Sensor (TSEP) and display cable (CXP) are the same as used with the current SMX platform.
- Easier menu-based programming.
- Smarter error/fault codes.
- Better serviceability (separate off-board compressor triac).
- Optional outside temperature display is available with an additional TSEP sensor.
- Optional humidity sensor/inside temp sensor available.
- Optional electric heat package can be added.
- Optional support adapter available for Dometic’s WhisperCool DC fan air handlers.
- Optional support for CAN-bus network interface.
SMXHT Price: $189.95 (Includes bezel)
(Black or White)
SMXHT Controls: The SMXht keypad/display is a microprocessor-based controller designed for the precise monitoring of self-contained and remote direct expansion air conditioning systems in marineenvironments. It is designed for use with the SMX II-HV power/logic board, operable on both Direct Expansion and Chilled Water systems. The SMXht keypad/display has a sleek, modern Euro design. Available in grey or white, it features raised buttons for easy access and control. Decorative snap-on bezels are available in Vimar® Idea or Gewiss® Playbus styles, and a variety of colors and materials to match your vessel’s interior.
- SMXht offers many great features. Line voltage and refrigerant high and low pressure switches are constantly monitored.
- If a problem is detected, the system will shut down and display a fault code on the keypad/display.
- A nonvolatile memory retains current operation mode and all programmable settings when power is turned off.
- Complete system monitoring on both DX and TW systems.
- Automatic humidity control – reduces moisture when the boat is unattended.
- Multiple fan speed selections – automatic or manual speeds.
- Blank the lit display when desired – keep cabin dark at night.
- Supports auxiliary heat for TW systems.
SMXir Price: $189.95
SMXir Controls: The SMXir keypad/display and optional remote control work with both DX microprocessor control systems offered by Cruisair – SMX II and SMX Net. SMX II logic systems offer all the standard operational and safety features required for most Direct Expansion systems. SMX Net logic systems add networking capability and other special features that make it unique in the industry. The SMX II or SMX Net power/logic board comes installed on the designated self-contained unit or condensing unit. Either logic system can be retrofitted in the field to replace an electromechanical switchassembly.
- The SMXir keypad/display has an attractive, compact housing.
- A large, easy-to-read LED display shows cabin temperature, setpoint, programming prompts, and fault code warnings.
- Small LEDs and backlit text indicate system status.
- SMXir features a plastic housing, sealed membrane keypad, and electronics with anticorrosion coating.
- Available in black or white, and with either a 3/4 or full coverage door.
- Dehumidification Program – reduces moisture when the boat is unattended.
- Low Voltage Shutdown; High/Low Pressure Shutdown.
- Remote System Control.
- Supports auxiliary heat when used with Net Board.
- Software Update Capability (SMX Net only).
SMXIIAB Price: $199.95
(Does not include snap on cover)
Electromechanical Rotary Knob Controls: Electromechanical rotary-knob switch assemblies provide conventional control over basic air conditioning functions. Both 115V and 230V switches are available. 3-knob assemblies provide function selection (Off-Fan-Run), fan-speed control, and a room thermostat. 2-knob assemblies for tempered water systems provide function selection (Off-Fan-Run) and fan speed control. (In these systems the thermostat is on the air handler.) 1-knob assemblies provide function selection only (Off-Fan-Run).
