  • Page 7: Zoning System Overview

    3.1 Airzone Controller The Airzone Controller is the main component of the zoning system. The controller is also the interface between the zoning system and the iQ Controller.

  • Page 8: Zone Control Module

    Control Module activates the damper motor accordingly and controls its operation. It is capable of sending error messages to the local Zone Thermostat and to the Airzone Controller if the damper is out of order or blocked. Also, the Zone Control Module communicates the temperature set point and measured zone temperature to the Airzone Controller.

    B) It runs a single 4 conductor, stranded and shielded cable to all system elements C) The dampers are powered open/powered close D) The way the Airzone Controller communicates with the Zone Control Modules is based on a communication protocol.

  • Page 10: Preparing The Cables For Wiring

    Another cause of installation problems is incorrect parameter setting. This can be avoided by writing down were each Zone Control Module is located and how are they configured (mainly Zone Control Module addresses, and master-subordinate relationships). 5.1 Preparing the cables for wiring All wires that will end in a connector should be prepared as shown below 1½...

  • Page 11: Wiring Recommendations

    Based on the wiring lay out diagram, the cable can be laid out starting from where the Airzone Controller will be installed, (normally next to the AHU or furnace), and from there to the closest damper, and thus following to the other dampers in the System.

    as available. This is the reason why it is recommended to use a separate thermostat to configure the Subordinate zone control modules. The figure above shows an example of a Master Zone with two Subordinate Zones. While the Master Zone will have ZCid=03 and tCId=0, indicating that it has a thermostat connected to it, the two Subordinate Zones have tCId=03, indicating that they are Subordinates of the Zone control module 03.

    13.4.2 Types of Bypass Dampers Airzone has two types of bypass dampers to be used depending on the installation. They are free release bypass dampers and ducted bypass dampers. The following requirements must be satisfied for any type of bypass damper whether free release or ducted: A) The bypass damper gate must not interfere with the airflow coming from the return.
  • Page 36 Airzone has two types of free release bypass dampers: rectangular and circular (the latter is characterized by the fact that it can be used in both free release or ducted bypass dampers. Traditionally, the rectangular bypass damper is installed in rectangular fiber ducts or sheet metal ducts while the circular bypass damper is usually installed in plenums with flexible ducts.

    Ducted Bypass Damper. This type of bypass damper releases the surplus static air pressure from the supply air duct to the return duct thus linking both ducts. These bypass dampers are specifically designed to be inserted into the supply duct in order to be connected with the return duct. The placement of this component is parallel to the supply air flow as shown in the following figure Fig.
