  • Page 17: Hardware Setup Options

    HARDWARE SETUP OPTIONS: On the thermostat’s circuit board, there is a row of DIP switches, labeled #1 through #8. The position of these switches will change how the thermostat operates, and also how information is conveyed to you on the LCD display screen.
  • Page 18 may be more convenient if you are typically home during the day, and only need the set temperature to be different while you are sleeping. SWITCH #4 (SCALE): [OFF/DOWN = F, default] All temperature values are displayed using the Fahrenheit scale. [ON/UP = C] This setting displays all temperature values using the Celsius scale.

  • Page 19: Complete The Install

    GAS / ELEC SLIDE SWITCH (FAN OPERATION): This switch is a physical component by itself on the circuit board, and is much larger than the DIP BATTERY switches listed above. [DOWN = GAS, default] This setting lets the heating system control the blower fan automatically by itself.
  • Page 20 thermostat’s “G” wire terminal, to control a blower fan. The Fan Mode switch has no effect in systems that do not have a blower fan (such as a hot water radiator system). MULTI-FUNCTION, SET SLIDE SWITCH: This switch provides an easy way to quickly access the most commonly used thermostat settings.

  • Page 21: Operating Instructions

    NEXT BUTTON: This button is mostly used while setting items such as software options, and temperature program periods. When there are several items on the screen that can be changed, usually one of them is flashing indicating that it can be adjusted.
  • Page 22 outdoor temperatures are too low to support efficient operation, but it could also prevent damage to the heat pump if outside temperatures are below the manufacturer’s recommendations. As every heat pump has different operating characteristics, you should refer to your heat pump literature to determine when to disable the heat pump and run in Emergency Heat mode.

  • Page 23: Temperature Programs

    TEMPERATURE PROGRAMS: By default, 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.

  • Page 24: Advanced Features

    ADVANCED FEATURES: TEMPERATURE SWING AND OFFSET SETTING: A thermostat works by turning your heating or cooling system on and off whenever the room temperature varies from the desired set-point temperature. The amount of this variation is called the swing. Generally your system should cycle on about 3 to 6 times per hour. A smaller swing number makes the system cycle more frequently, so the room temperature is more precise and constant.
  • Page 25 Cut-In / Cut-Out Stage) 70˚F Set Temperature Swing Setting= #2 (+/- 0.5˚F) Offset ** Setting= 4˚F degrees Stage) ** Cut-In / Cut-Out DEGREES (F) ** = Only applies if a second heat stage is present...
  • Page 26 TEMPERATURE CALIBRATION: The internal temperature sensor in this thermostat is accurately calibrated at the factory, and in most cases alterations to this setting should not be needed. The Temperature Calibration feature allows you to manually offset the measured temperature by as much as plus or minus 5°F (3°C) degrees from its original value.
  • Page 27 desired set temperature that will be used for the Setback duration. Just like the previous step, you can either wait for the screen to advance on its own, or press the NEXT button to advance and return to the Normal Run screen. TO CANCEL A SETBACK: While in the Normal Run screen, press and hold the SETBACK button for at least 2 seconds.
  • Page 28 the UP/DOWN buttons to select the proper code to access the cool limit setting. Press the NEXT button to accept the setting. If the code you tried was not correct, the thermostat will exit and return to the Normal Run screen with no changes made.
  • Page 29 GRAPHICAL AIR FILTER MONITOR: In most systems that use a blower fan and air ducts, there is an air filter that is either replaceable or requires cleaning. The filter is usually located in the air handler, where the blower fan is. This thermostat feature assists you with keeping track of proper maintenance and/or periodic replacement intervals for your system’s filter.
  • Page 30 HARDWARE RESET: The Hardware Reset button (labeled “HW RST”) is a small round push button that is located towards the HW RST right side if the circuit board, just below the battery holder. Pressing this button will cause the LCD display screen to become fully populated, the heating and cooling load relays to cycle off, read the position of the Hardware Setup Option switches, and will perform an internal system check of the thermostat...

  • Page 31: Battery Replacement

    BATTERY REPLACEMENT: This thermostat is powered by two “AA” Alkaline batteries. The batteries should be replaced AT LEAST once per year to ensure reliable operation (or sooner, if the “LOW BATT” icon appears at the top of the display screen). The batteries are located on the back of the thermostat, at the top of the circuit board.
