SMXII PWR LGC FOR MOD SYS/HV
PLHMX-HV, SMX II P/L Box Modulating Systems, 115/230V. Each cooling unit (or evaporating unit) in a modulating system requires its own control. There are two options: The SMX II microprocessor system or three-knob electromechanical switch assembly. The SMX II microprocessor control system consists of a PLHMX-HV power/logic module, SMXir keypad/display (one for each evaporating unit), CXP cable, and a TSEP temperature sensor. The PLHMX-HV power/logic module includes a 3 ft (0.9 m) wire harness that connects to the evaporating unit’s junction box. The CXP cable, available in many different lengths, connects the SMXir keypad/display to the PLHMX-HV. The TSEP temperature sensor, also available in different lengths, plugs into the PLHMX-HV. The TSEP’s sensor bulb is installed in the return air path. The SMXir keypad/display has an attractive, compact housing available in black or white. The display includes a mounting plate for easy surface-mount installation. A large, easy-to-read LED shows cabin temperature, set point, programming prompts, and fault code warnings. Small LEDs and backlit text indicate system status. Under a decorative hinged door is the membrane-sealed SMX 10-button keypad with clearly labeled keys for single-keystroke operation. Internal electronics have an anti-corrosion coating. An optional infrared remote control is available. For more information about the SMXir keypad/display, including dimensions, please refer to specification sheet L-2088. The three-knob electromechanical switch assembly is available in two varieties: The SA1 for cooling only systems, and the MS5 for units with electric heat. Knobs control mode, fan speed, and a thermostat. These controls come with a 10 ft. (3 m) capillary tube, 3 ft. (0.9 m) wire harness.
