The SeaMach™ reverse cycle air conditioners can be controlled by either a wall mounted digital thermostat or by the MachAir™ II, an electronic thermostat/controller with an OLED display.

The MachAir II is a digital thermostat/controller that provides temperature and humidity control, allows for fan speed adjustment and shows fault conditions in a compact, yet easily readable display. The MachAir™ II thermostat/controller is designed to operate with SeaMach™ self contained and split systems models with cooling capacities of 5,000 to 24,000 BTUH. The SeaMach OLED (Organic Light Emitting Diode) is the latest in display technology with features not available in other, less advanced systems. OLED (Organic Light Emitting Diode) displays are brighter, thinner, lighter and use less power than older LCDs. In addition, OLED's offer wider viewing angles and higher contrast than LCDs.

The thermostat/controller is easily programmed to allow the user to customize the operation of the SeaMach unit. Intuitive icons enable the viewer to see at a glance the operating status of the unit and the cabin temperature. Other features include:

• Recessed four position touch pad with push on / push off control
• Heat-Cool-Auto-Dehumidify modes
• Auto and manual fan speed control
• Operates on either a 115/230 VAC 50/60 Hz power supply
• Monitors operation of the SeaMach unit and display fault conditions
• Integral room sensor
• Display compatible with Gewiss and Vimar cover plates
