COMPATIBILITY
This programmable thermostat is compatible with Single or Double pole, 120/240 VAC, line voltage electric heating systems up to 16 Amps. The heating wattage rating is 1900 Watts (Resistive) for 120 VAC, and 3800 Watts (Resistive) for 240 VAC. This thermostat can also be used with 120/240 VAC line voltage Hydronic (hot water) heating systems with motors up to 1/4 HP.
6.Bend the solid conductors, and then push them and the wire connectors into the electrical box carefully, providing enough clearance behind the mounting screw locations. Secure the thermostat base to the electrical box with the mounting screws.
7.Place the thermostat front portion onto the back plate by first catching the plastic tabs at the top, and then firmly pressing the bottom of the thermostat towards the back plate to latch the halves together.
NOTE:
When you are finished performing your installation and setup options, please remove the thin plastic film that is protecting the LCD display screen on the front of the thermostat. This plastic may or may not be present, and is evident by the appearance of fake digits appearing on the display screen.
8.Install two new Energizer® or DURACELL® "AA" size alkaline batteries before continuing further. Ensure that the batteries are installed in the proper direction as per the markings shown in the battery tray. The battery tray is located in the front of the thermostat, behind the door.
9.Now turn the supply power back on to the heating system.
On the thermostat screen, ensure that the Power Unit Disconnected Indicator (shown at right) is not present on P
the display screen. If it is, remove the front half and try mating the front half to the back half again.
NOTE:
This thermostat is protected against normal static electric
discharges, however to minimize the risk of damaging the unit in
extremely dry weather, touch a grounded metal object before
touching your thermostat.
A temperature Hold may be used for days, weeks, or even months at a time. To enter a Hold, push the HOLD button once, and the word“HOLD” will appear in the temperature portion of the screen, along with the flashing set temperature. While the set temperature is flashing, push either the UP or DOWN button to the new desired set temperature value. To cancel a Hold, press and release the HOLD button once again, or rotate the dial away from RUN.
ADVANCED FEATURES
SWING SETTING:
A thermostat works by turning your heating system on and off whenever the room temperature varies from the set-point temperature. The amount of this variation is called the “swing”. Your system should cycle on about 3 to 6 times per hour. A smaller swing number increases the number of cycles per hour, so the room temperature is more precise and constant. A larger swing number decreases the number of cycles per hour, but saves energy in most cases. To change the Swing setting, turn the dial to RUN mode. Hold down the NEXT button and push the HOLD button once, then let go of both. A single number will appear on the screen. Use the UP/DOWN buttons to change the number value between 1 and 9. Number 1 is the default setting. Press the NEXT button to accept the setting and return to normal Run mode.
MINIMUM RUN TIME DELAY:
This is determined by the thermostat, and controls the minimum length of time that the thermostat must remain with the Heat either On or Off, before it will automatically switch to the alternate On or Off state. This feature prevents rapid undesired cycling of the heating equipment. The time amount for this delay is fixed at 5 minutes between on or off load changes.

INSTALLATION
Please read ALL of these instructions carefully before beginning installation. Save them for future reference.
W A R N I N G
•This Thermostat is a line voltage (120/240 VAC) control. Do not attempt to install it unless you are completely familiar with line- voltage wiring. If improperly handled, there is a risk of electric shock hazard which may cause serious injury or death.
•The thermostat is rated for normal full load current from a double 20A circuit breaker or fuse block. Do not use on circuits with current protection devices that are rated higher than 20 amps.
•Maximum load for this thermostat MUST NOT exceed 3800 Watts, otherwise a potential fire hazard exists.
MOUNTING LOCATION:
Install a vertical, electrical switch box for mounting the thermostat approximately 5 Feet (1.5 Meters) above the floor on an inside wall where the thermostat will be exposed to average room temperature. The use of a “deep” style switch box will make the installation easier by providing more room for making the wiring connections. The thermostat must be placed away from concealed warm or cold water pipes, air ducts, or drafts from hallways, direct sunlight, fireplaces, or stairways in order to sense room temperature properly. Do not place the thermostat directly above any of the heating elements.
CAUTION
Turn off electricity to your heating system prior to installing this thermostat, or servicing any part of the system. Do not turn electricity back on until installation is fully completed.
WIRING:
1.Disconnect power before removing your old thermostat (if applicable). Double check that this thermostat is rated for the voltage and amperage to be switched.
2.Remove the front portion of the thermostat by carefully pressing the button at the bottom of the thermostat and swinging the body up and away.
3.When replacing an old line voltage wall thermostat, remove it carefully to avoid damage to the insulation on the wiring. Check the old insulation for cracks, nicks, or fraying and apply certified electrical tape where necessary to achieve adequate insulation, or replace the wires in an approved fashion.
4.Use the diagrams shown in the “WIRE IDENTIFICATION AND WIRING SCHEMATICS” section of this manual to ensure that the thermostat connections are made to the proper wires for your installation.
5.Attach the wires together using the solder-less wire connectors (provided), and be sure that all wire connectors are tight and secure.
NOTE:
Wiring performed must comply with all applicable national electrical
codes and local ordinances for your particular area.
The hardware reset is a push button that is located near the center of the circuit board. This reset button is used by the thermostat to read the position of the option switches. When either of the two option settings above are changed, the hardware reset button must be pushed for the change to be recognized. This can also be used if the thermostat is exhibiting any erratic behavior. User temperature programs are not erased when a hardware reset is performed, however you will have to set the clock and day of the week.
FRONT PANEL ITEMS
SOFTWARE RESET:
The Software Reset is a small recessed push button that is located to the right of the NEXT and HOLD buttons. This button can be pushed with a pencil or the end of a paper clip. The software reset clears all of the user temperature programs, and all other software preferences to their default values. You should write down your heating program times and temperatures prior to using the Software Reset.
PUSH BUTTONS: | | | | | |
There are four primary push buttons on the front | | | | | | | |

OPERATING INSTRUCTIONS
SET DAY/TIME:
Rotate the dial to the SET DAY/TIME position. The day of the week will start flashing on the display. With the day flashing, press the UP button, once for each day, to advance to the desired day of the week. Press the NEXT button; this should cause the time to start flashing and the day to remain on steady. Using either the UP or DOWN buttons, adjust the clock to the desired time. The clock digits will increment rapidly if either the UP or DOWN buttons are held in the pressed position.
TEMPERATURE OVERRIDE:
A Temperature Override occurs in Run mode, anytime the user adjusts the set temperature to a value other than what the stored program set temperature is for that day and time. When the thermostat is in an Override, the word “OVERRIDE” will appear in the bottom of the display screen. The thermostat will maintain thermal control using this new set temperature, until the start of the next program period time is reached. At that time, the set temperature will return to the value stored in memory for that new program period. To enter an Override, push either the UP or DOWN button once and the set temperature will begin to flash. Push either the UP or DOWN button to the desired set temperature value. An Override may be cancelled by rotating the dial or by initiating a HOLD.
TEMPERATURE HOLD:
A Temperature Hold is similar to an override, but is used for maintaining a constant set temperature under manual control, for a longer time duration. A Hold is the simplest means to set and maintain a fixed temperature. It allows you to set and maintain a fixed temperature indefinitely, without concern for programming.
periods. When you are finished setting all four periods, you may continue pushing the NEXT button through all four periods to review your entries, or turn the dial to RUN if you are finished.
SET WEEKEND PROGRAM:
Turn the dial to WEEKEND PROGRAM. You will be programming both Saturday and Sunday at the same time. You will begin with the start time of the MORN period, and use the same procedures that were performed while setting the Weekday Program periods, using the NEXT button to advance through the values. Return the dial to the RUN position when you are finished.
BATTERIES AND MAINTENANCE
The batteries should be replaced AT LEAST once per year, or sooner if the LOW BATT battery symbol appears in the lower left portion of the display screen as shown. To replace the batteries in the thermostat, open the front door of the unit. The battery
compartment is located just below the rotary dial and push buttons. Pull the battery compartment out, starting with the top edge. Remove the used batteries from the battery tray and discard appropriately.
Install two new Energizer® or DURACELL®, “AA” size alkaline batteries into the battery tray. Observe the polarity markings shown in the battery compartment to ensure proper installation. When finished, re-install the battery compartment by first seating the bottom into its alignment pins, and pivoting the top in towards the thermostat to snap the latch back into place.
