Lux ELV4 Advanced Features

Swing ADJUSTMENT:
The thermostat works by turning the heating system on and off when the room temperature deviates from the set temperature. The size of this variation is called the "swing". Your system will power up about 3 to 6 times per hour. The smaller the number of oscillations, the higher the number of cycles per hour, so the room temperature is more accurate and constant. A larger number of oscillations reduces the number of cycles per hour, but in most cases saves energy. To change the swing setting, turn the dial to RUN mode. Hold down the NEXT button and press the HOLD button once, then release both. A number appears on the screen. Use the UP / DOWN button to change the number value between 1 and 9. The number 1 is the default. Press the NEXT button to accept the settings and return to normal operation.

MINIMUM TIME TO COMPLETE THE JOB:
This is determined by the thermostat and controls the minimum time the thermostat must keep the heater on or off before automatically switching to an alternate on or off state. This function prevents the heater from turning on and off quickly and accidentally. The time for this delay is set at 5 minutes between switching on and off

Lux ELV4 Front Panel Overview

SOFTWARE RESET:
The software reset is a small concave button located to the right of the NEXT and HOLD buttons. This button can be pressed with a pencil or the end of a paper clip. A software reset will clear all user temperature programs and all other software settings to their default values. You should log the time and temperature of your heating program before using a software reset.

KEY:
There are four main buttons on the front of the thermostat: the UP and DOWN arrow keys, the NEXT button and the HOLD button.

ROTATION SPEED:
LUX Speed ​​Dial ® provides an easy way to quickly navigate between different programming areas. This rotating disc has four separate positions.

TURN OFF THE HEATING / CONSUMER:
This switch is located on the front of the power supply (back half of the thermostat). To access this switch, separate the front and back of the thermostat by pressing your thumb under the bottom of the thermostat and pulling the front of the thermostat away from the back. In winter, set the power switch to the "HEAT" position to control your heating system. During the hot summer months when heating is not required, set the switch to the "OFF" position to prevent components of your heating system from turning on.

Lux ELV4 Installation

Please read ALL of these instructions carefully before beginning installation. Save them for future reference.

INSTALLATION LOCATION:
Install a vertical electrical junction box to mount the thermostat approximately 1.5 meters from the floor in an interior wall where the thermostat will be exposed to the average room temperature. Using an "inside" electrical box makes installation easier because there is more room for connecting wires. The thermostat should be located away from recessed hot or cold water pipes, corridor air or exhaust ducts, direct sunlight, chimneys or stairs to properly sense the room temperature. Do not place the thermostat directly over any heating element.

Lux ELV4 Wiring

  1. Turn off the power before removing your old thermostat (if you have one). Make sure this thermostat has the rated voltage and current to be activated.
  2. Remove the front of the thermostat by gently pressing the button on the bottom of the thermostat and turning the housing up and to the side.
  3. If replacing an old wall voltage thermostat, remove it carefully to avoid damaging the wire insulation. Check old insulation for cracks, breaks, or scuffs, and if necessary, use certified electrical tape to obtain adequate insulation or replace cables in an approved manner.
  4. Use the diagrams in the "CABLE IDENTIFICATION AND HANGING DIAGRAM" section of this manual to ensure that the thermostat connections are made to the correct wires for your installation.
  5. Secure the cables with solderless cable connectors (supplied), making sure all cable connectors are tight and tight.
  6. Bend the solid cable and carefully slide it into the electrical box along with the cable connector, leaving sufficient space behind the fixing screws. Secure the thermostat base to the control box with the fixing screws.
  7. Place the front of the thermostat onto the back plate by first holding the plastic teeth on the top and then pressing the bottom of the thermostat firmly against the back plate to lock the two halves together.
  8. Install two new Energizer ® or DURACELL ® AA size alkaline batteries before proceeding. Make sure the battery is installed in the correct direction according to the markings on the battery holder. The battery compartment is in front of the thermostat behind the door.
  9. Now reconnect the power supply to the heating system. From the thermostat display, make sure that the power off indicator (shown at right) does not appear on the display screen. If this is the case, remove the front and try mating the front with the back again.

Lux ELV4 Wiring

Lux ELV4 Setup Option

The settings, options, and components listed below in this section are located on the back of the thermostat on the circuit board.

CHOICE:
On the right side of the circuit board is a square box with 2 small switches. Each switch controls a different setting depending on the switch position. The individual switches are marked 1 and 2 and the table corresponding to the possible options for each of the two switch positions is printed on the circuit board.

TEMPERATURE SCALE (Option Switch 1):
This determines how the thermostat displays all screen temperatures. The OFF position is F° and ON is C°. TIME FORMAT (Optional Switch #2): This determines how the thermostat displays the clock and all other times on the screen. The position of the OFF switch is 12 hours and ON is 24 hours.

HARDWARE RESET:
Hardware reset is a button near the center of the board. This reset button is used by the thermostat to read the position of the option switch. If any of the above two option settings change, the hardware reset button must be pressed to detect the change. It can also be used if the thermostat shows erratic behavior. The custom temperature program is not erased when a hard reset is performed, but you must set the hour and day of the week.

Lux ELV4 Operation Instuction

DAY/HOUR SET:
Turn the dial to the SET DAY / TIME position. The day of the week starts flashing on the screen. With the day flashing, press the UP button once for each day to move to the desired day of the week. Press the NEXT button; This should start the flashing time and the day should remain steady. Use the UP or DOWN button to set the clock to the desired time. The hour digits will increase rapidly if the UP or DOWN button is pressed.

OPEN TEMPERATURE:
A temperature wipe occurs in Run mode whenever the user adjusts the setpoint temperature to a value different from the value set in the program setpoint temperature for that day and time. When the thermostat is in override mode, the word "OVERRIDE" will appear at the bottom of the display screen. The thermostat will maintain the heat setting at this new setpoint temperature until the start of the next programming period is reached. At this point, the set temperature will return to the value stored for the new programming period. To enter cancel, press the UP or DOWN button once and the set temperature will start flashing. Scroll up or down to set the desired temperature set point. Cancellation can be canceled by turning the control wheel or by triggering HOLD.

TEMPERATURE HOLDING:
Temperature maintenance is similar to the reverse, but is used to maintain a constant setpoint temperature over a long period of time during manual control. Retention is the easiest way to regulate and maintain a steady temperature. Allows you to set and maintain a constant temperature indefinitely without worrying about programming. Temperature maintenance can be used for days, weeks or even months. To enter hold, press the HOLD button once and the word "HOLD" will appear in the temperature area of ​​the screen along with the set temperature. While the set temperature flashes, scroll up or down until the desired new temperature setting point is displayed. To release the hold function, press and release the HOLD button again or turn the RUN dial.

For the two types of programs described below, this thermostat offers four independent times of day for heating modes: MORNING, DAY, NIGHT, and NIGHT. Each period ends at the start time of the next period. When you first insert the battery or perform a software reset, the default temperature program (see below) is entered into all four program periods. You can use the program by default or customize any part to suit your own preferences. When setting program items, flashing values ​​are items that you can change at that time.

Lux ELV4 Programming

MANAGE PROGRAM SCHEDULE:
Turn the dial to PROGRAM WORKSHOP. You program all five workdays simultaneously. The first period is TOMORROW. Use the UP and DOWN buttons to set the start time for this period and then press the NEXT button to continue. Now set the desired set point temperature for the MORNING period using the UP and DOWN scroll buttons and press FORWARD to continue. Now set the start time and temperature for the TAG period by pressing NEXT to continue. Continue with the same steps to set the start time and temperature for the EVE and NITE programming periods. Once you have set all four periods, you can keep the NEXT button pressed during all four periods to view your track, or turn the RUN knob when you are ready.

MAKE WEEKEND PROGRAM:
Turn the END OF WEEK PROGRAM knob. You program Saturday and Sunday at the same time. You start with the start time of the MORN period and use the same procedure used when setting the program period of the week, using the NEXT button to scroll through the values. When finished, return the disk to the RUN position.
