LUX LP0511D Instalation and Operation Instructions

LUX LP0511D Instalation Manual

This thermostat can be used with most single-stage 24 volt: gas, oil or electric heating and cooling systems, single-stage heat pumps, or gas Millivolt heating systems. It cannot be used with: 3-wire zone valves, 120/240 volt heating elements, or multi-stage heat pumps. Ask your dealer for other LUX thermostats to control those systems.

LUX LP0511D Instalation

Remove Old Thermostat

  1. Turn OFF the electricity to all heating and cooling components. Do not turn the electricity back on until all work is completed.
  2. Remove the front portion of your old thermostat to expose the wiring connections.
  3. Write down the letters printed near each wire terminal that is used, and also the color of each wire that is connected to it. Self-adhesive wire labels are also enclosed.
  4. Carefully remove the wires one at a time, and bend them in a manner so that they do not fall back inside the wall. Do not allow bare wire ends to touch each other.
  5. Loosen the mounting screws for the old thermostat and carefully remove it from the wall.

Thermostat Mounting Location

On replacement installations, mount the new thermostat in place of the old one unless the conditions listed below suggest otherwise. On new installations, please follow these general guidelines:

  1. Mount the thermostat on an inside wall, about 5 ft. (1.5m) above the floor.
  2. Do not locate the thermostat where air circulation is poor such as in a corner, alcove, or behind a door that is normally left open.
  3. Do not locate the thermostat where unusual heating or cooling conditions may be present, such as: direct sunlight, above a lamp, television, or radiator, or on a wall next to an exterior door or window.
  4. Do not locate in a damp environment, as this can lead to corrosion that may shorten thermostat life.
  5. If painting or construction work is still ongoing, cover the thermostat completely or wait until this work is complete before installation.

Instalation New Thermostat

  1. Strip wire insulation leaving only 3/8 in. (9.5mm) bare wire ends, and clean off any corrosion present.
  2. Fill the wall opening with non-combustible insulation to prevent drafts from affecting the thermostat’s normal operation.
  3. Route the wires through the opening in the new thermostat base plate, and hold the base against the wall. Try to line up the screw holes from the prior thermostat, and install the mounting screws.
  4. If the previous holes cannot be used, hold the thermostat base against the wall so that it appears straight and level (position the base for best appearance) and mark for the new screw holes. Attach the base to the wall using the screws provided (use the supplied plastic anchors if needed when mounting to a soft material such as drywall).

LUX LP0511D Wiring Terminal Connections

  1. When attaching the wires to the thermostat, please ensure that the bare wire ends are held ALL the way into the terminal block while the screw is being tightened.
  2. Securely tighten all of the electrical terminal screws, including any unused ones. Be careful not to over tighten the screws, they only need to be snug.

** Complete heating and/or cooling system wiring can be found in the WIRE IDENTIFICATION AND WIRING SCHEMATICS section of this instruction sheet. The schematics shown provide component information for brand new installations or for unreferenced wires.

LUX LP0511D System Configuration and Setup Option

On the circuit board, there are hardware settings called “jumpers”. Each jumper has 3 metal pins, and a small black cap. The cap is moved to either the top two pins or the lower two pins. Changes to these options are recognized every time the HEAT/OFF/COOL mode switch is moved.

JP1 (CTRL): [UP = Manual Operation] The thermostat operates manually, and only shows the room and set temperatures. In this mode, there are no temperature programs, days of the week, or clock times. [DOWN = Program Operation, default] The thermostat follows four temperature programs: MORN, DAY, EVE, and NITE. Each period has a start time and a set temperature.

JP2 (SCALE): [UP = Celsius] This setting displays all temperature values in C˚ degrees. [DOWN = Fahrenheit, default] All temperature values are displayed in F˚ degrees.

JP3 (BATT): [UP = None] This setting only applies if you are NOT using batteries in the thermostat, and are powering the thermostat entirely from the system (“C” wire terminal). [DOWN = Batt, default] This setting, regularly monitors the battery level, and shows “LOW BAT” on the screen if the batteries need replaced. Use this setting at all times when batteries are physically present in the thermostat.

JP4 (HP): [UP = Heat Pump] Use this setting if you have a heat pump unit (which looks just like an outside air conditioning unit, but is used for both cooing and heating). [DOWN = non-HP, default] This setting is used for the majority of all heating systems that are not heat pumps. Examples for this setting would be: natural gas furnace, hot water baseboard heat, and oil heat.

JP5 (FAN): [UP = Electric / HP] This setting runs the system’s blower fan when heat is called for, and is required for systems that do not control their own fan while in HEAT mode. Heat pump systems, and units with an electric heating element typically require this setting. [DOWN = Gas, default] This setting lets the heating system control the blower fan automatically by itself. Types of systems that would typically use the “Gas” fan setting would be: natural gas furnace, propane furnace, and oil furnace.

JP6 (B/O): [UP = “B”] This setting energizes the “B/O” wire terminal at all times in HEAT mode, and is not energized in COOL mode. This setting is not typical, and is only needed for certain brands of heat pump units, such as: Rheem, Ruud, Goettl, and Bard. [DOWN = “O”, default] This setting energizes the “B/O” wire terminal at all times in COOL mode, and is not energized in HEAT mode. This setting is used for the majority of heat pump units with the exception of only a few brands.

LUX LP0511D Thermostat Front Panel

HEAT / OFF / COOL, SYSTEM MODE SWITCH: Set this switch to HEAT to control your heating system, and COOL to control your cooling system. The OFF position will disable both the heating and cooling units.
AUTO / ON, FAN SWITCH: When this switch is in AUTO, the blower fan (if present in your system) will automatically cycle on and off by itself when heating or cooling is running. When in the ON position, the blower fan will run constantly with or without a demand for heating or cooling, even in OFF mode.

MULTI-FUNCTION, SET SLIDE SWITCH: Unless other settings are being adjusted, this switch should always remain in the RUN position for the thermostat to control temperature. When this switch is in the DAY/TIME position, the day and clock can be changed. When this switch is in the WEEKDAY or WEEKEND positions, the heating and cooling temperature program periods can be adjusted. NOTE: this switch is only used in “Program” mode. When the thermostat is used in “Manual” control mode, all four of the switch positions will act like the RUN position.

RESET BUTTON: There is a small recessed push button located to the left of the DOWN button, which can be pressed with a pen/pencil, paper clip, or similar object. A single press of this button causes the LCD display screen to become fully populated, the heating/cooling load relay to cycle off, and
performs an internal system check of the thermostat components. If your thermostat is acting in an erratic manner, pressing the Reset button may remedy this behavior. If your thermostat continues to act erratically, a Full Software Reset may be needed. This and other additional features that can be accessed using the same Reset button, which are explained in the ADVANCED FEATURES section of this manual.

LUX LP0511D Thermostat Basic Operation

SET DAY AND TIME: Place the Set Slide Switch into the DAY/TIME position. With the day flashing, press UP or DOWN to set the day of the week. Press NEXT and the clock will start flashing. Use UP or DOWN to set the time, making sure the AM/PM indication is correct. Holding UP or DOWN will make the clock digits scroll rapidly. Return the Set Slide Switch to RUN.

HEATING AND COOLING: Basic operation of your heating or cooling system can be obtained with the Set Slide Switch in the RUN position and choosing either HEAT or COOL on the System Mode Switch. When the thermostat is first powered up, it will follow a default temperature routine that is preset from the factory (shown below).

TEMPERATURE OVERRIDE: While in Program mode, the set temperature can be temporarily changed by pressing UP or DOWN. The set temperature will return to the programmed value stored in memory when the start time of the next upcoming program period is reached (MORN, DAY, EVE, NITE). While a Temporary Override is in effect, the word OVERRIDE will be shown in the display screen. An Override may be cancelled moving the mode switch to OFF, then back to HEAT or COOL.

MINIMUM RUN TIME: The thermostat has an internal time delay of 5 minutes between load-on and load-off activations to prevent heating or cooling system damage, which can occur from very frequent cycling. If heating or cooling does not turn on right away with a change in set temperature, please wait 5 minutes and the system should resume normal operation.

TEMPERATURE HOLD: A Temperature Hold is used for maintaining a fixed set temperature. Once a Hold is initiated, the thermostat will maintain the set temperature indefinitely. A Hold may be used for days, weeks, or even months at a time. To enter Hold mode: press HOLD one time and the word Hold will appear in the display. To cancel a Hold, press HOLD one more time.

STATIC NOTICE: This thermostat is protected against normal minor static electric discharges, however to minimize the risk of damaging the unit in extremely dry weather, please touch a grounded metal object before touching your thermostat.

LCD DISPLAY BACKLIGHT: The display screen has backlighting that will assist viewing at nighttime, or in locations with low light levels. A press of any button on the front panel will light the display for approximately 10 seconds. Any button presses that occur while the backlight is on, will reset the timer, causing the screen to remain illuminated for an additional 10 seconds.

LUX LP0511D Temperature Program

This thermostat has 4 separate program periods for both Heat and Cool mode, they are: MORN, DAY, EVE, and NITE. Each period ends at the start time of the following period. The heat programs are set in HEAT mode, and the cool programs are set in COOL mode.

WEEKDAY PROGRAMS: Move the Set Slide Switch to WEEKDAY. You will be programming all five weekdays at the same time. Use UP or DOWN to adjust the start time for the MORN period, then press NEXT to advance. Use UP or DOWN to adjust the set temperature for the MORN period, then press NEXT to advance. Now adjust the start time and set temperature for the DAY period, pressing NEXT after each to advance. Continue with these same steps to adjust the start times and set temperatures for the EVE and NITE program periods. When you are finished setting all four periods, continue pressing NEXT to review your entries for all 4 periods. Move the Set Slide Switch to the RUN position if you are finished, or to WEEKEND to adjust the periods for Saturday or Sunday periods.

WEEKEND PROGRAMS: Move the Set Slide Switch to WEEKEND. You will be programming both Saturday and Sunday at the same time. You will begin with the start time for the MORN period, and use the same steps that you did for setting the Weekday periods, pressing NEXT to advance through the values. Return the Set Slide Switch to the RUN position when you are finished.
