Section 4. Zoning Setup
STEP 1 - Enable Zoning
Enter the Installer Setup section on the 950/1050
Control:
Home screen --> Menu --> Service --> Technician
Access* --> Proceed --> Installer Setup
Move through the Standard Installation Set Up
options and Enable Zoning on the first screen of
Group 2.
Important: Must use a Trane/American
Standard manufactured indoor unit with a
variable speed blower. If a TAM9, TEM8, or TAM8
air handler is being used, verify the Airflow
Mode selected on the air handler CDA or 7
segment display is set to Constant CFM.
STEP 2 - Damper Travel Time
Select the travel time that matches the dampers.
NOTE:
Trane and American Standard dampers
use a 60 second travel time.
NOTE:
The zone control can handle many types of
dampers, but all dampers in the system must have
the same drive time (15 to 60 seconds) and must
be power open/power close. Spring controlled
dampers are not allowed. See the damper
installation guide for additional information.
STEP 3 - Auto Detect Dampers
The zone control will send out a signal to open and
close the dampers when “Yes” is selected. The
control will see the load on each damper slot and
automatically configure the number of zones with
dampers detected.
STEP 4 - Manually Detect Dampers
The dampers will be automatically checked if auto
damper detection was selected.
The technician will need to manually select the
appropriate dampers if auto damper detection is
not used.
Required Steps before enabling zoning:
1) Zone Panel must be powered (24VAC transformer)
2) Zone Panel must be connected to communicating bus (D, B)
3) All non-communicating zone temperature sensors must be connected to corresponding zone slots
4) All communicating zone temperature sensors must be addressed to corresponding zone number
5) All dampers should be installed and connected to corresponding zone slot
6) Discharge Temperature Sensor must be connected
7) Install and wire Differential Static Pressure Sensor and probes (only required for Auto Zone Sizing)
