Zone Panel
ZZONEPNLAC52ZB (Kit)
ZZONEEXPAC52ZB (Zone Panel)
ALL phases of this installation must comply with NATIONAL, STATE AND LOCAL CODES
IMPORTANT - Proper application is critical when installing zoning systems. Not done correctly, the HVAC
and zoning systems will not provide the expected comfort. Reference application bulletins CNT-APG003-
EN/Trane and CNT-APG004-EN/AS for detailed information on Zoning Application
IMPORTANT - This Document is customer property and is to remain with this unit. Please return to service informa-
tion pack upon completion of work.
These instructions do not cover all variations in systems or provide for every possible contingency to be met in connection with
the installation. Should further information be desired or should particular problems arise which are not covered sufficiently for the
purchaser's purposes, the matter should be referred to your installing dealer or local distributor.

  • Page 17 STEP 5 - Auto Zone Sizing The zone control has the ability to energize the blower and modulate dampers to determine how much air each zone can handle. The Static Pressure kit is required to use Auto Zone Sizing. NOTE: All zones less than 25% cannot be a voting zone (See STEP 7).
  • Page 18 MANUAL ZONE SIZING Auto Zone Sizing is the optimal way to determine the amount of air flow into each zone, but this process is not mandatory. Zone sizes can be set manually using the following guidelines. EXAMPLE (highlighted below): A 2-zone, 3-ton AC system is configured to move 1200 CFM. Zone 1 has a 12”...
  • Page 19 ZONE SIZING EXAMPLE: The zone size has a direct impact on system operation and homeowner comfort. The system uses zone sizes to determine the air handling capability of each zone and determines the amount of excess air that has to be managed.
  • Page 20 EXAMPLE: A home has a 5-ton single stage AC system with 3 zones. Zone #1 is a 6 inch duct that feeds the laundry room. Since this zone is sized less than 25%, the zone is forced to non-voting and should not be allowed to energize the equipment.
  • Page 21 STEP 8 - Indoor Heating Airflow Offset% The air flow offset is the difference between cooling and indoor heating (fossil/electric) air flow. The control uses this offset to calculate and manage excess air. EXAMPLE: The system is a 3-ton AC configured at 1200 CFM. The furnace is configured to move 960 CFM.
  • Page 22: Section 5. Zone Sensor Setup

    Section 5. Zone Sensor Setup The Zone Sensors Screen is used to associate temperature sensors with zones. The Zone Sensor Setup Screen is compromised of two sections: Select Zone/Damper and Available Sensors. STEP 1 - Select Zone/Damper All enabled zones will be displayed in the left column of the Zone Sensor Setup.
  • Page 23 STEP 4 - Assign Remaining Sensors Repeat Steps 1-3 until all zones have been assigned a sensor. STEP 5 - Exit Sensor Setup When all zones have been assigned a sensor, press “Done.” Note: All zones must be assigned a temperature sensor before exiting the Service Menu.
  • Page 24: Section 6. Damper Test Mode

    Section 6. Damper Test Mode Damper Test Mode gives the user the ability to open specific dampers to verify the dampers are performing properly. Each damper can be driven independently or in any combination. The blower will operate during an active damper test.
