    thermostats plus: 
    Enhanced Comfort  
    Ñ Allows  the 
    homeowner to accurately maintain the 
    desired temperature and humidity 
    settings in the home. By combining the 
    functions of a programmable/non-
    programmable thermostat and a 
    humidistat, the Thermidistat Control 
    provides temperature control, humidity 
    control, and dehumidiÞcation. 
    Humidity Control  
    Ñ The Thermidistat 
    Control accurately controls humidity level. 
    It controls humidiÞcation during heating and dehumidiÞcation during cooling.  
    Automatic Humidity Adjustment   
    Ñ 
    When used with the outdoor temperature 
    sensor, the Thermidistat Control 
    automatically adjusts the humidify 
    setting, reducing excess condensation 
    from forming on the windows.  
    Vacation mode   
    Ñ With a single touch 
    of a button, vacation mode adjusts all 
    comfort levels for optimum efÞciency 
    while the home is unoccupied Ñ or 
    restores the settings to normal upon return.  
    Smart Recovery   
    Ñ Provides consistent 
    heating and cooling right on time as it 
    gradually adjusts indoor temperatures 
    before a scheduled change.  
    Equipment On Indicator   
    Ñ When 
    the cooling equipment is operating, the 
    word COOL preceded by a small triangle 
    is displayed below the cooling set point. 
    When the heating equipment is 
    operating, the word HEAT preceded by a 
    small triangle is displayed below the 
    heating set point. If the equipment turn 
    on is being delayed, the triangle and the 
    word will ßash.  
    Non-Programmable Option   
    Ñ Offers 
    the same popular humidity control 
    beneÞts to consumers who do not need 
    the added beneÞts of programming. Nine 
    functional buttons, along with the UP and 
    DOWN buttons, make it easy to enter the 
    temperature and humidity set points. The 
    LCD is the largest display on the market

    This timer prevents the compressor from starting unless it has been off for at least 5 minutes. It can be defeated for 1 cycle by 
    simultaneously pressing the FAN mode button and INCREASE TEMPERATURE (UP) button.
    Fifteen-minute cycle timer
    This timer prevents the start of a heating or cooling cycle until at least 15 minutes after the last start of the same cycle. Its 
    function is to assure that equipment is not cycled more than 4 times per hr. This timer is defeated for 1 cycle when the desired 
    temperature is manually changed. It can also be defeated for 1 cycle by simultaneously pressing the FAN button and the 
    INCREASE TEMPERATURE button.
    Fifteen-minute staging timer
    In multistage heating or cooling, this timer prevents any higher stage from turning on until preceding stage has been on for 15 
    minutes. This timer is defeated if temperature error is greater than 5¡F (usually due to a large change in desired temperature).
    Minimum on time
    In normal operation, when a stage turns on, it will not turn off for a minimum of 3 minutes (2 minutes on BuilderÕs model).
    Heat/Cool set points (desired temperature)
    A minimum difference of 2¡ is enforced between heating and cooling desired temperatures. This is done by allowing one 
    setting to ÒpushÓ the other, to maintain this difference. (Thermidistat Control is adjustable.) BuilderÕs thermostats are 
    controlled by a single set point.
    Equipment on indicators (Non-Programmable models)
    When cooling equipment is ON, a COOL ON icon is displayed above the room temperature display. When heating equipment 
    is ON, a HEAT ON icon is displayed above the room temperature display.
    Equipment on indicators (Thermidistat Control)
    When cooling equipment is ON, a COOL icon preceded by a small triangle is displayed below the cool set point. While 
    cooling equipment turn on is delayed by a staging or cycle timer, the triangle and the word COOL will ßash. The same is true 
    for the HEAT icon and its preceding triangle located under the heat set point. The 2 triangles are also used to indicate the state 
    of the humidify and dehumidify outputs. See next section.
    Humidify/dehumidify output on indicators (Thermidistat Control)
    Within humidity select screen (selected by Humidity button and indicated by ÒhuÓ or ÒdhuÓ on clock display), the triangle 
    under humidity set point will be on while humidify output is on. The triangle under dehumidify set point will be on while 
    dehumidify output is active (turned off, because this output is reverse logic).
    Auto changeover
    When auto changeover mode is selected, a change from heat to cool (or vice versa) will not occur until an opposite mode 
    demand has existed for 20 minutes. If set point is changed, the 20 minute requirement is deleted. Auto changeover mode can 
    be disabled. BuilderÕs and Standard Programmable thermostats are manual changeover.
    Emergency heat mode
    When thermostat is controlling a heat pump and emergency heat is selected, all Y signals are locked out, and W becomes 
    energized upon a call for heat.
    Smart Recovery (Programmable models)
    With Smart Recovery selected, transition out of setback begins a Þxed time period before selected recovery time and gradually 
    adjusts room temperature so that the desired temperature will be achieved at selected recovery time. 
    Room Temperature Offset (All models)
    Room temperature may be deliberately offset by up to 5¡F in either direction.
    Maximum On/Off Deadband
    Maximum sensed temperature difference between ON and OFF is 0.8¡F for BuilderÕs thermostats and 0.6¡F for all other 
    models.
