    Important Concepts To get the most out of your system, you should understand the concepts described in this section. In addition, see page 56 for a system diagram and a simple explanation of how the system works. 1. Your personal comfort range 5.
  • Page 10 Important Concepts The lower and upper limits must differ by at least three degrees. We recommend a six-degree separation. Most users don’t notice a few degrees of difference as long as they are inside their comfort range. However, one degree outside the comfort range can be uncomfortable. Therefore, the system’s priority is to keep every room inside its comfort range.
  • Page 11 Our System Works With Your Existing HVAC Equipment The MyTemp system works with the HVAC equipment you already have. When the system senses that one or more rooms aren’t within their comfort zones, it initiates a heating or cooling cycle using your HVAC equipment. Your equipment (like all residential HVAC equipment) requires a certain amount of airflow to work effectively.
  • Page 12 In general, the default settings are a good balance between comfort and energy savings. However, the importance of comfort versus energy savings varies from person to person. The MyTemp system provides the information and adjustments necessary to enable you to control...

The following suggestions are described in detail later in this manual. • Use the widest comfort ranges possible. Decrease the lower limits to use less heating and increase the upper limits to use less cooling. •...
  • Page 14 Important Concepts The simplest way to reduce conditioning is to change the upper or lower limit of the comfort range for that room, especially during peak conditioning hours. You can also improve the room’s insulation by using window treatments (blinds, tinting, curtains, and so on); adding more insulation to outside walls, ceiling, and floor;...
  • Page 15 HVAC design, forcing a compromise in the location of the HVAC equipment, the supply duct system, or the return-air paths. Without special care, remodeling almost always increases HVAC supply ducting and return problems. The MyTemp system does an excellent job of compensating for mistakes and weaknesses, and keeps all rooms as comfortable as physically possible.
  • Page 16 Important Concepts The simple and unexpected solution was to take the unused room out of saver mode so that it also received air conditioning. The airflow through three ducts was enough to cool the top floor so the temperatures in all three rooms dropped into their comfort ranges. Circulation immediately started, mixing the warmer top-floor air with the cooler bottom-floor air.

    Selecting a Thermostat Mode You can choose one of three thermostat modes to control your home’s temperature, as follows: Basic: This is the simplest mode. Basic mode allows you to set a lower limit and an upper limit for the entire house. The system applies your settings to all rooms in the house, but only conditions rooms that go outside their limits.
