ComfortLink II / AccuLink Zoning

Zoning Webex 08/25/112

• Launch date is 08/29/11

• Approved applications for initial release:– Trane/American Standard Indoor unit with a variable speed blower

PWM control of the indoor blower is required for the 1st release– Wired sensors

Wireless sensors are currently being tested and are scheduled to release mid to late October

• Non Approved applications for initial release:– Bypass control scheme

Since the software to support bypass resides in the Zone Panel, a Zone Panel change will be required

• A 950 control is required for all zoning applications– The 950 control is the central control point for all system functionality,

including zoning

• Version 2.0 software is required for zoning operation All 950 controls built after 9/22/11 will have version 2.0 software Zoning cannot be enabled with software versions 1.0 & 1.1 Existing inventory of version 1.0 and 1.1 controls must be sold through before

version 2.0 software will be available

• Control software can be updated two ways:– Internet upgrade on control

Requires valid wireless connection and SD card– Software download to SD card via Trane.com or Americanstandardair.com

XL950 / Platinum ZV Control


• New Features (2.0)– Zoning capability (with Zone Panel and Wired Sensors)

All zoning related features are documented in the Zone Panel IG– Schlage Link compatible (non-zoning only)

Training presentation is loaded on FSR Forum– Improved diagnostics

• Improvements– Photo Album screensaver is now persistent after a power cycle– CFG.004.00 (No Humidity Sensor) is now a Normal alert and

diagnostics have been corrected– Weather feature has been completely re-architected to improve

connectivity



• ZZSENSAL0400A is a non-display temperature sensor only

• ZZSENSAL0400A is the same part that is used with the TCONT402 thermostat

• When using a ZZSENSAL0400A as a zone sensor, set point and mode can be adjusted at 950 control

ZZSENSAL0400A Wired Indoor Temperature Sensor


• The sensor requires two wires which are connected to the corresponding slot on the Zone Panel

• Zone 1 can be controlled by either the onboard sensor of the 950 control or a wired sensor

• ZZSENSAL0400A does not have humidity sensing capability

Zone Panel User Interface

• User Interface Menu– System Status– Zone Status– Information– Alerts

• User Interface is the best place to get up-to-date external duct static– Value displayed on 950 control is

not updated unless “Refresh” button is pressed


• All zoning instructions will be included in the Zone Panel literature

• This includes the steps required to setup a zoning system in the 950 control

Installation Guide


There are three options for zone dampers:•Round•Round Retrofit (slide in)•Rectangular

Zone Damper


The position indicator provides an easy reference point to view damper movement

Electrical connections. The connections “COM, PO & PC” are the same between the zone panel and actuator

Damper release button. Press this button releases the gears and allow the damper to be adjusted manually

The part number and power consumption is listed on each actuator

Zone Damper Actuator



• The 950 control has advanced diagnostic capability– All critical alerts will be displayed on the home screen and flash a

“RED” icon on the shortcut bar Critical Alerts disable heating/cooling operation

– All major alerts will display a “Yellow Icon” on the shortcut bar of the 950 control Major Alerts disable some functionality but heating/cooling operation is

possible– Normal Alerts are logged but not displayed to the end consumer

Normal Alerts are fault conditions that may interfere with system operation but will clear on there own


Advanced Diagnostics

• Diagnostic Screen will display all alerts regardless of severity– Current Alerts (active alerts only)– Alert History (alerts which have been negated)

• In the Diagnostic screen all alerts will have a Problem Description and Possible Cause listed– Current Alerts will display the time the alert was asserted– Alert History will display the time the alert was cleared



• New Alert Messages – There are certain alerts which disable zoning, but heating/cooling

operation will be maintained– These alerts are categorized as Major since heating/cooling operation is

still possible (examples below) SOP.04.00 Indoor Temperature Sensor Fault SOP.04.50 Discharge Temperature Sensor Fault SOP.04.54 Four DTS trips within 1 hour



• Disable Zoning continued…– Heating/cooling operation will be controlled by the temperature

sensor in the largest zone (highest zone size/weight)– All dampers will be driven to full open position– These alerts will display a pop-up on the zones which are disabled

and also indicate which zone is controlling heating/cooling operation

– Once the alert condition is cleared the system will automatically revert back to zoning operation









• New Alert Messages– There are certain alerts which disable heating/cooling operation– These alerts are categorized as Critical since heating/cooling

operation is not allowed (examples below) ERR91 Communication Fault ERR126 Communication device missing/changed






Summary Table

• In the previous example we showed an Err.126.00 which defeated system operation

• Err.126.00 indicates either equipment missing or changed

• A Summary Table has been added which will list all communicating devices and the current status of each device to assist in troubleshooting


Summary Table

• Here the Summary Table shows three communicating devices, two are online and one is offline

• The offline device is what created the Err.126.00

• Two Zone Expanders have been created with the same serial number because the zone dip switch was changed after initial power up


Summary Table

• Once the dip switch is changed to the correct position the online/offline status changed


Summary Table

• Select the “Offline” device and press “Remove Selected Offline Devices”


Summary Table

• The “Offline” device has now been removed

• The Err.126.00 will now be cleared and system operation will resume

• The Summary Screen allows for “Offline” devices to be removed without using the “Restore Factory Settings” which clears all settings


Look for even more advanced diagnostics in revision 2.1 software
