INSTALLATION AND WIRING
When this Comfort Control is replacing an old thermostat that contains mercury in a sealed tube, do not dispose of your old thermostat in the trash. Dispose of it properly. Contact your local waste management authority for instructions regarding recycling and proper disposal of the old thermostat. A listing of heating, ventilating, and air conditioning wholesalers that participate in the Thermostat Recycling Corporation’s recycling program is available at www.thermostat-recyle.org.
Temperature Sensing Considerations
The Silver 724 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.
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.
Mark two mounting holes using a new wall plate.
Install a new wall plate
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.
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.
Attach the Comfort Control face to the wall plate.
Turn the power to the heating and cooling system back on. The Comfort Control display should turn on and begin displaying information. Proceed to Installer’s Setup to configure system settings.

Caution: Do not run sensor wires in the same bundle with HVAC wires. Keep away from high voltage wiring to avoid interference
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.
Remote Temperature Sensor Connections and Operation
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.
| Troubleshooting | ||
| Symptom | Possible Cause | Action |
| Display will not come on | Loss of 24VAC between R & C at the Control | 1) Check wiring between R & C 2) Check transformer for 24VAC output 3) Check for broken or shorted thermostat wire |
| Indoor Temperature display is incorrect | 1) Indoor temperature display needs calibrating (always allow 1 hour before calibrating after any power cycle) 2) Heat from the touchscreen is being trapped within the body of the control | 1) Calibrate indoor temperature sensor 2) Relocate the control away from any competing air sources or redirect the air sources away from the control |
| Indoor humidity display is incorrect | Indoor humidity sensor needs calibrating | Calibrate humidity sensor |
| Room temperature overshoots the desired setpoint in cooling mode | 1) The delta “Off” in cooling mode is set to a negative number 2) Cooling overshoot is enabled and the indoor RH is higher than the target cooling RH 3) Minimum compressor on time has not been met | 1) Intended operation; if objectionable, change the delta “Off” to 0 degrees 2) Intended operation: if objectionable, disable cooling over- shoot or raise cooling target RH 3) Intended operation; if objectionable, change Control Response settings in the Installers Settings, Comfort Settings Menu |
| Room temperature overshoots the desired setpoint in heating mode | Minimum compressor/indoor heat on time has not been met | Intended operation; if objectionable, change control response settings in the Installers Settings, Comfort Settings Menu |
| Cooling will not come on | 1) System mode is not set to Cool/Auto or setpoint is set too high 2) Delta “On” for cooling is set too high 3) Minimum off time delay is being enforced 4) Cooling system may need service | 1) Select the correct system mode and/or lower the setpoint 2) Change the delta “On” setting for cooling mode 3) Intended operation; if objectionable, change Control Response settings in the Installers Settings, Comfort Settings Menu 4) Check/repair system |
| Heating will not come on | 1) System mode is not set to Heat/Auto or setpoint is set too low 2) Delta “On” for heating is set too high 3) Minimum off time delay is being enforced 4) Heating system may need service | 1) Select the correct system mode and/or raise the setpoint 2) Change the delta “On” setting for heating mode 3) Intended operation; if objectionable, change Control Response settings in the Installers Settings, Comfort Settings Menu 4) Check/repair system |
| Heating or Cooling is being displayed, but no air coming from registers/ vents | 1) Fan delay time has not expired 2) System is not operating properly | 1) Wait one minute for blower delay to end, then recheck register/grills 2) Check/repair system |
| Fan runs all the time | 1) Fan mode is set to “On” or “Circ” 2) System is not operating properly | 1) Intended operation; if objectionable, change fan mode to “Auto” 2) Check/repair system |
| Fan is set to “On” but not running | 1) Smart continuous fan (SCF) is enabled and the indoor humidity is higher than the cooling target RH (SCF will be displayed on fan mode button) 2) System is not operating properly | 1) Intended operation; if objectionable, disable SCF or raise cooling target humidity 2) Check/repair system |
