SILVER 724 INSTALLER'S GUIDE

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

Remote 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.

ODT ODT

Outdoor Sensor

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.

Troubleshooting

Symptom Display will not come on
Indoor Temperature display is incorrect
Indoor humidity display is incorrect Room temperature overshoots the desired setpoint in cooling mode
Room temperature overshoots the desired setpoint in heating mode Cooling will not come on
Heating will not come on
Heating or Cooling is being displayed, but no air coming from registers/ vents Fan runs all the time Fan is set to "On" but not running

Troubleshooting

Possible Cause

Action

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

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 sensor needs calibrating

Calibrate humidity sensor

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
Minimum compressor/indoor heat 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 overshoot or raise cooling target RH 3) Intended operation; if objectionable, change Control Response settings in the Installers Settings, Comfort Settings Menu
Intended operation; if objectionable, change control response settings in the Installers Settings, Comfort Settings Menu

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) 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) Fan delay time has not expired 2) System is not operating properly

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
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
1) Wait one minute for blower delay to end, then recheck register/grills 2) Check/repair system

1) Fan mode is set to "On" or "Circ" 2) System is not operating properly
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, change fan mode to "Auto" 2) Check/repair system
1) Intended operation; if objectionable, disable SCF or raise cooling target humidity 2) Check/repair system
