INTRODUCTION

Thank you for your confidence in our product. To obtain the best results from your investment, please read this manual and acquaint yourself with your purchase before installing your new thermostat. Then follow the installation procedures, one step at a time. This will save you time and minimize the chance of damaging the thermostat and the systems it controls. These instructions may contain information beyond that required for your particular installation. Please save for future reference.

TOOLS REQUIRED

• 1 Phillips screwdriver (small)

• Wire Stripper
• Drill

COMPATIBILITY

LUX PSDH121+ is designed for use with single stage heat pump systems with auxiliary and/or emergency heat. These systems are typical known as 2-stage heat one stage cool heat pump systems.

FEATURES

• Vertical or Horizontal Orientation
• Large easy to read backlit display
• Mode and Fan control for ease of use
• Simple Temperature UP and Down Control.
• Calibration control
• Temperature Swing adjustability (9 levels)
• 2 or 5 minute compressor delay
• Fahrenheit or Celsius selection
• Temperature Limits for High and Low selections
• Test mode to temporarily disable the compressor delay

OPERATING INSTRUCTIONS

• In the winter, set the system switch to HEAT to control your heating system.
• In the summer, set the switch to COOL to control your air conditioner.
• Press either the TEMPERATURE UP or DOWN key in order to show the current SET TEMPERATURE.
• Press TEMPERATURE UP or DOWN keys again until your desired temperature is displayed. The display will show the current room temperature again after two seconds.
• Press the light bulb button to illuminate the display. Adjusting the temperature will keep the display lit until no button has been pressed for over ten seconds.
• In spring and fall or when windows are open, you can set the system switch to OFF.
• Setting the FAN switch to AUTO automatically runs your system’s fan during heating and cooling.
• Setting the FAN switch to ON runs your system’s fan continuously even without heating or cooling.
• Setting the Mode switch to EMER (emergency heat) runs your Emergency heating system rather than the heat pump.

INSTALLATION

• Turn off electricity to the appliance before installing or servicing thermostat or any part of the system. Do not turn electricity back on until work is completed.
• Do not short (jumper) across electric terminals at control on furnace or air conditioner to test the system. This will damage the thermostat and void your warranty.
• All wiring must conform to local codes and ordinances.
• This thermostat is designed for use with 24 volt and millivolt systems.
• The thermostat should be limited to a maximum of 1.5 amps; higher current may cause damage to the thermostat. If you are in doubt, call your HVAC contractor.
• Your thermostat is a precision instrument. Please handle it with care.

THERMOSTAT LOCATION

• On replacement installations, mount the new thermostat in place of the old one unless the conditions listed below suggest otherwise. On new installations, follow the guidelines listed below.
• Remember that your PSDH121+ may be mounted vertically or horizontally when determining the optimal location.
• Locate the thermostat on an inside wall, about 5 ft. (1.5m) above the floor, and in a room that is used often.
• Do not install it where there are unusual heating conditions, such as: in direct sunlight; near a lamp, radio, television, radiator, register, or fireplace; near hot water pipes in a wall; near a stove on the other side of a wall.
• Do not locate in unusual cooling conditions, such as: on a wall separating an unheated room; or in a draft from a stairwell, door, or window.
• Do not locate in a damp area. This can lead to corrosion that will shorten thermostat life.
• Do not locate where air circulation is poor, such as: in a corner or an alcove; or behind an open door.
• Do not install the unit until all construction work and painting has been completed.

REMOVING THE OLD THERMOSTAT

• Switch electricity to the furnace and air conditioner OFF; then proceed with the following steps.
• Remove cover from old thermostat. Most are snap-on types and simply pull off. Some have locking screws on the side. These must be loosened.
• Note the letters printed near the terminals. Attach labels (enclosed) to each wire for identification. Label and remove wires one at a time. Make sure the wires do not fall back inside the wall.
• Loosen all screws on the old thermostat and remove it from the wall.

MOUNTING THE PSDH121+ ON THE WALL

• Decide whether the thermostat will be mounted vertically or horizontally.
• Strip insulation 3/8 in. (9.5mm) from wire ends and clean off any corrosion.
• Fill wall opening with non-combustible insulation to prevent drafts from affecting the thermostat.
• Grip the device per the diagram below to remove the front plate from the back plate.

NOTE  If you are mounting the base to a soft material like plasterboard or if you are using the old mounting holes, the screws may not hold. Drill a 3/16- in. (4.8mm) hole at each screw location, and insert the plastic anchors provided. Then mount the base as described below

ATTACHING WIRES
Route the wires through the large hole in the base plate by the terminal block. Hold the base against the wall, with the wires coming through. Position the base for best appearance (to hide any marks from an old thermostat). The terminal block should be either to the right of or below the routing hole. Attach the base to the wall with the two screws provided.
