Page 21: Normal Operation
CTK03 ComfortNet™ Communicating Thermostat Basic and Advanced Temperature Control Options (ISU 3010) Basic Options: The Installer Setup displays basic temperature control options which include Backup Heat Differential, Backup Heat Upstage Timer and Outdoor Temperature Lockouts. Note: Outdoor Temperature Lockouts only apply to Heat Pump applications. Advanced Options: The Installer Setup displays both Basic and Advanced Options. Advanced temperature control options include Finish With High Cool Stage, Finish With High Heat Stage, Temperature Differential settings between all stages 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 22 System Installation Guide Humidification The thermostat reads the indoor humidity level and allows the user to set a humidification setting with or without window protection. Window Protection Window Protection limits the amount of humidity to prevent frost or condensa- tion on windows. Window Protection (ISU 8050) requires an outdoor sensor. The maximum humidity level that is allowed ("Window Limit") is displayed on the Humidification Settings screen. The thermostat prevents frost or condensation on windows by not allowing the humidity to go above the Window Limit when it is controlling the humidifier. This helps inform the user as to why their humidity setting might not be reached at times. The Window Limit is based on the current outdoor temperature and the user's window protection setting. If Window Protection is turned Off, the ther- mostat controls the humidity level to the user's desired humidity setting. Frost or con- densation may appear on windows. To see all humidification options, press MENU > INSTALLER OPTIONS > VIEW/EDIT CURRENT SETUP > HUMIDIFICATION. Dehumidification - Residential The thermostat reads the indoor humidity level and allows the user to set a dehu- midification setting.
- Page 23 CTK03 ComfortNet™ Communicating Thermostat Dehumidification - Commercial The thermostat reads the indoor humidity level and allows the user to set a dehumidification setting. Dehumidification using the cooling system has the following methods of dehumidification control (ISU 9080): Basic: This option uses the cooling system to reach the desired humidity level. Minimum On Time and High Humidity Comfort Reset are not used with this method. This option should only be used if the equipment can lower the fan speed in a call for dehumidification. Minimum on Time (ISU 9090): This option ensures that the compressor runs long enough to effectively reduce humidity when the cooling equipment is cycled on. The compressor will run for the minimum "on time" you set until the desired humidity level is reached. High Humidity Comfort Reset (ISU 9100): This option uses the cooling system to lower the temperature up to 5 F below the current cool setpoint until the desired humidity is reached. The high humidity comfort range is from 1 to 5 F. High Humidity Comfort Reset with Minimum On Time (ISU 9090 and ISU 9100): This method uses both options above to reduce humidity while maintaining a comfortable temperature.
- Page 24 System Installation Guide Dehumidification Away Mode Dehumidification Away Mode protects the home when unoccupied for long periods of time during hot and humid weather by maintaining the desired humidity and temperature settings. To start Dehumidification Away Mode, press Menu, then press Dehumidification Away Mode. The thermostat automatically follows settings that are set by the dealer during installer setup. Press Cancel to end Dehumidification Away Mode. Southern Dehumidification Away Mode Options: (ISU 9180 to 9200) • Fan: Auto, On or Circulate • Low Limit Temperature Setting: The thermostat allows the cooling system to lower the indoor air to the Low Limit Temperature Setting to control humidity. • Temperature Setting: The temperature maintained while Dehumidification Away Mode is active and the desired humidity level is satisfied. • Dehumidification Setting: The desired humidity level while Dehumidification Away Mode is active.

Page 25: Temperature Control
CTK03 ComfortNet™ Communicating Thermostat 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. -
