MERCURY NOTICE

PHYSICAL LOCATION
Temperature Sensing Considerations
The XR724 Control is designed for installation in climate-controlled living spaces. It is recommended to place the unit in central locations with good circulation. Avoid exterior walls and areas near windows, doors, vents or concealed pipes or chimneys. 

1. CAUTION: ELECTRICAL HAZARD 
   CAUTION: Before proceeding with installation, verify system power has been removed. Separate the face of the new Comfort Control from the wall plate.
   NOTE: It is not recommended that this WiFi Comfort Control be mounted onto metal structures. Metal may adversely affect the radio frequency (RF) communication between the Comfort Control and the WiFi network.
2. Mark two mounting holes using a new wall plate.
   • Pull wires through hole in the center of wall plate.
   • Locate the new wall plate over the existing opening.
   • Mark two holes with a pencil.
   • Use a level to verify that the two hole locations are level.
   • Correct hole locations as needed.
3. Install new wall plate.
   • Pull wires through hole in the center of wall plate.
   • Locate the naew wall plate over the existing opening.
   • Attach wall plate to the wall using two screws provided. Do not over-tighten.
4. Attach all wires securely to the new Comfort Control. 
   (See the Field Wiring Diagrams on the following pages.)
   Note: A wire must be connected to “C” to power the Comfort Control.
   • Use the information from the Field Wiring Diagrams to match the wires to the correct terminals.
   • Use 1/8” blade screwdriver to secure wires in terminals.
     CAUTION: EQUIPMENT DAMAGE HAZARD
     Improper wiring can lead to equipment damage. Use the field wiring diagrams to ensure the Comfort Control is wired properly. After wires are secure, bare wires MUST NOT touch each other. See the Field
     Connection Wiring Diagrams on the following pages for specific system applications.
5. Attach the Comfort Control face to the wall plate.
   • Carefully align the face plate to the wall plate while aligning pins into wire terminals.
   • Once Comfort Control face is properly aligned, apply pressure at top and bottom of
     Comfort Control face until it is secure.

Optional Remote Temperature Sensor Installation
Wire specification for remote sensors: 2 conductors, 18 gauge wire. Make sure that the sensor wires are installed in a separate cable from the wiring to the HVAC system. Best results for distances of 100 feet or less. Accuracy may be affected for distances up to a maximum of 200 feet. Shielded cable is recommended for distances over 100 feet and less than 200 feet.
CAUTION: Keep this wiring at least one foot away from large inductive loads such as electronic air cleaners, motors, line starters, lighting ballasts, and large distribution panels. Failure to follow these wiring practices may introduce electrical interference (noise) which can cause erratic system operation. Shielded cable is required if the above wiring guidelines cannot be met.
Be sure to ground only one end of the shield to the Comfort Control common terminal. Tape back the other end of the shield.

Remote Sensor Part Numbers
Remote Indoor Sensor: Use ZZSENSAL0400AA for indoor applications.
Remote Outdoor Sensor: Use BAYSEN01ATEMPA for outdoor applications.

• IMPORTANT: Make sure that the sensor wires are installed in a separate cable from the Comfort Control cable.
• IMPORTANT: Follow directions below for averaging. These instructions replace the averaging information found in the Installer’s Guide for the ZZSENSAL0400AA.

Remote Temperature Sensor Connections and Operation:

• A) Indoor sensor connected to RS.
  The Remote Sensor (RS) function can be configured in the Service/Installer Settings/Sensor Settings menu. Options are:
  • None
  • Replaces onboard temp sensor of the Comfort Control
  • Averages with onboard temp sensor
    Replace – RS Sensor replaces the internal temperature sensor of the Comfort Control. This allows the Comfort Control to be installed in a location different than the area where the temperature will be measured. Use ZZSENSAL0400AA.
    Average – RS Sensor averages its temperatures with the internal sensor. Use ZZSENSAL0400AA.
• B) Outdoor sensor connected to ODT. Reports outdoor temperature to the Comfort Control.
  The Outdoor Sensor (ODT) function can be configured in the Service/Installer Settings/Sensor Settings menu. Options are:
  • None
  • Outside
    Outside – ODT (outdoor temperature sensor). If ODT sensor is selected and connected, the outdoor temp is displayed on the main screen. ODT model is BAYSEN01ATEMPA.
