Advanced temperature control options include Finish With High Cool Stage, Finish With High Heat Stage, Temperature Differential settings per stage and Cycle Rate settings per stage. Finish With High Heat or Cool Stage - When a multi-stage heating or cooling system is used, this feature keeps the high stage of the heating or cooling equipment running until the desired setpoint is reached.
  • Page 21 THX9321/9421 Prestige IAQ and RF EIM ® Humidification The thermostat can be set to control humidification in all modes (Heat, Off, Cool [ISU 8060]). A discharge air sensor is required to humidify in the cool mode. If both humidification and dehumidification are set up to be controlled in the same mode (Heat, Off, Cool), the thermostat maintains a 15% deadband between humidification and dehumidification setpoints. The thermostat automatically switches between humidification and dehumidification to maintain the desired humidity level.

  • Page 23 THX9321/9421 Prestige IAQ and RF EIM ® Southern Dehumidification Away Mode This feature lowers the temperature up to 3° F below the setpoint as needed to prevent excessive humidity while the home is unoccupied. Southern Dehumidification Away Mode options: (ISU 9180 to 9200) • Fan Control: Auto, On or Circulate • Low Limit Temperature Setting: Lowest temperature allowed to control humidity. • Temperature Setting: Temperature is maintained when dehumidification is not needed. • Dehumidification Setting: Humidity level desired while Dehumidification Away Mode is active. You can control humidity with a dehumidifier or a cooling system. If a cooling system is used, humidity is controlled by cooling indoor air to the Low Limit Temperature Setting. When the desired humidity level is reached, the system will maintain the Southern Dehumidification Away Mode temperature setting. Ventilation The thermostat can be set for the following ventilation types: (ISU 10000) • ERV/HRV • Passive (Fan Only) • Fresh Air Damper Ventilation Control Methods (ISU 10060) • ASHRAE: Operation of ventilation equipment meets the ASHRAE 62.2 Ventilation Standard based on CFM, number of bedrooms and square footage of home.

  • Page 24: Temperature Control

    System Installation Guide Indoor sensor operation Temperature control The thermostat can be set to respond to its internal temperature sensor, or to an option- al remote indoor sensor. If multiple sensors are used, the thermostat will respond to an average of temperatures detected at each sensor. Humidification control If optional remote indoor sensors are installed, you can choose which sensor you want to use for humidification control. You can use a different sensor for dehumidifica- tion. Dehumidification control If optional remote indoor sensors are installed, you can choose which sensor you want to use for dehumidification con- trol. For example, you can use one sensor for humidification control, and another for dehumidification. Wireless indoor sensor Battery level indicators (when batteries are inserted) Good: Status light flashes green for 5 seconds.
