Section 1. General Information 1.1 Overview This sensor is a wall mounted low voltage control that allows a user to control the temperature in the respective zone. The sensor can be used in two different ways: • • Stand-alone remote indoor temperature and relative humidity sensor. Temperature and relative humidity* sensor used to control individual zones in zoning applications. * For zoning applications, relative humidity control is a system-level function.
Section 2. Operation Display Selection 2.1 Buttons and Indicators 1 Notification Icons Room Temperature System Status Indoor Temperature Indoor Relative Humidity Humidity PM Current Time Outdoor Sensor Displays Outdoor Temperature or Humidity if available. Touch to alternate. Outdoor Hold Hold 5 Maintains the current setpoints permanently or until a chosen time.
IMPORTANT: Do not use household cleaners or spray cleaners, including water spray to clean the 940 zone sensor screen or enclosure. Household cleaners and sprays may cause permanent damage to the zone sensor. 1 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.
2 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. 3 Presets - Three presets allow one-touch control of conditions.
4 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. 5 Hold - This sensor offers three variations of Hold functionality that override the scheduled setpoints. Temporary Hold Permanent Hold Hold Until NOTE: The Hold button is only visible when a schedule is enabled on the 950 Control. Press Cancel Hold to resume schedule.
Temporary Hold - This feature temporarily overrides the scheduled setpoints until the next scheduled period. Indoor Temperature Humidity 1) Adjust Setpoint - Adjust the setpoint to the desired setting by pressing the up and down arrows. After approximately 5 seconds, the screen will display Holding Until with the time of the next scheduled period. To cancel, press Cancel Hold. Permanent Hold - This feature is used to permanently override the scheduled setpoints.
Hold Until - This feature overrides the scheduled setpoint until a user selected time is reached. 1) Press Hold Two Times - Press Hold two times to enter Hold Until mode. 2 Indoor Temperature Humidity 2) Adjust Setpoint - Adjust the setpoint to the desired setting. 3) Set End Time - Set the time to return to the scheduled setpoints. 3 The screen will show Holding Until with the selected time. To cancel, press Cancel Hold. When a 940 Sensor is following a schedule, the screen will appear in this manner.
2.2 940 Sensor’s Screen Layout The screen layout of the 940 Sensor can be customized through the 950 Control. MENU > SETTINGS > SCREEN SETTINGS > ZONE SENSOR Select the desired display settings. These settings will update on the 940 Communicating Sensor after selecting APPLY.
NOTE: If a zone without a 940 Communicating Sensor is currently displayed, the following screen will appear. Please note the zone in the top left. Press either of the green arrows to switch to the appropriate zone.
Section 3. Installation 3.1 Contents and Specifications The following parts are included in product model AZONE940AC52Z: 1121- Communicating Sensor Base Mounting screws/anchors Installation/User’s Guide Specification Description Product Model: AZONE940AC52Z Product: AccuLink™ Communicating Sensor Size: 5.5” width x 3.4” height x 1.
3.2 Zone Sensor Location Considerations The 940 Communicating Sensor is designed for installation in climate controlled living spaces. It is recommended to place the sensor in central locations with good circulation. Avoid exterior walls and areas too near windows, doors, vents or concealed pipes or chimneys. Important: If an air source is directed at or above the sensor, heat from the screen can be trapped within the sensor body and can cause the indoor temperature to be biased.
3.3 Physical Mounting Remove cover by grasping at edges and gently pulling the cover straight towards you. It should release without much effort. Be sure wires are routed through the center of the base plate and are long enough to connect to terminals. For convenience multiple hole patterns are provided. Select and mark two opposing holes. A level may be used to ensure accuracy.
Mounting to studs: Drill 1/8” pilot holes in the 2 locations marked above. OR Mounting to drywall: Drill 3/16” pilot holes for anchors (included with the control) in the 2 locations marked above. Gently tap anchors into the holes. D R DRILL HOLES 1/8” for screws into studs 3/16” for drywall anchors 14 B Attach base to wall using 2 screws provided. Do not overtighten.
3.4 Wiring Connect power leads to the D, R and B terminals. • Wire data to D. • Wire 24 VAC hot to R. • Wire common to B. D B R Seal Hole NOTE: All wall penetrations MUST be sealed to prevent temperature biasing. !

3.5 Setting Zone Address Indoor Temperature Setting up the 940 Sensor is a two-step process. 2 1 System Zone Setup Number BOTH steps MUST be performed. Setting STEP 1 – Setting the 940 Sensor’s address: 1. Verify that the Setup Number is “1” and if not adjust it using red/blue arrows. 2. Select SYSTEM ZONE address by adjusting with black arrows. SETTING display will not adjust until setting is accepted below. 3. Pressing DONE saves changes and exits the setup screen.
STEP 2 – Assigning the 940 Sensor to the corresponding damper in the 950 Control. 1 2 1. Go to the 950 Control 2. Navigate to: MENU > SERVICE > TECHNICIAN ACCESS > PROCEED > ZONE SENSORS. 3. Select the corresponding damper on the left side of the screen. 4. Select the appropriate sensor on the right side of the screen 3 5. Press ASSIGN. Repeat these steps for all communicating sensors. See the Zone Panel literature for more information. Scan to see a video on how to set up zoning with the 940 Sensor.
NOTE: If you need to re-enter this setup screen, press and hold INDOOR TEMPERATURE for approximately 5 seconds. Important: Once the 940 Sensor’s address has been selected and the sensor has been associated to a zone in the 950 Control, changing the address at the 940 Sensor will have no effect on the zone assignment. To change zone assignment, see below. 3.
3.7 Optional User Display Settings The setup screen allows changing of display settings. These features can be adjusted by changing the SETUP NUMBER and changing the SETTING range in the same manner as the Zone Address was set in the previous section. Please see the matrix below. NOTE: To enter this setup screen, press and hold INDOOR TEMPERATURE for approximately 5 seconds.
