    * For zoning applications, relative humidity control is a system-level function. The 950 Control allows the user to select the humidity-controlling zone.
    * NOTE: For proper operation, some features of the 940 Sensor require software version 2.2 or later on the 950 Control. Before proceeding, please be sure the 950 Control is running software version 2.2 or later.

Trane XL940 Operation

Icons

Alert Triangle – A critical alert has been detected. Contact servicing dealer.
Signal Icon – The communicating sensor has lost communication. Contact servicing dealer.
Lock Icon – Indicates the screen has been locked by the 950 Control. When this lock is present, the sensor will not respond to any keypad presses.

Setpoints - The setpoint is the desired temperature for each mode (Heating or Cooling).

Select the heating or cooling button to adjust the temperature for that mode. Using the red or blue arrow, adjust the temperature up or down. If scheduling is enabled on the 950 Control, changing the setpoint on the 940 Sensor overrides the scheduled setpoint until the next scheduled period. See the Hold section for additional information.

Presets - Three presets allow one-touch control of conditions.

Note: buttons will not be present if disabled from the 950 Control. (See Section 2.2) These preset buttons on the 940 Sensor are configured from the 950 Control and allow one-touch convenience for the common situations of Home, Away or Sleep.
These preset values are temporary and will revert to the 950 Control’s scheduled settings at its next scheduled period.

Fan Mode - Fan Mode is a system-level function. Changing the fan mode at any sensor will change the system fan mode to reflect the last fan setting.
