3.2 Zone Control Module
The Zone Control Module is another important part of the system. There will be one Zone
Control Module per Damper.
The Zone Control Module is the interface between the Airzone controller, the damper, and the
thermostat. When the Airzone Controller commands to open or close the dampers, the Zone
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.
The Zone Control Module stores all parameters related with the zone and has additional
capabilities such as:
1) accepting inputs from window or door contact switches
2) motion detector input
3) optional remote temperature sensor input
If the Zone Control Module detects a communication error with the thermostat or an operation
failure with the associated damper motor, it will send an error message to the Airzone
Controller, which in turn will relay it to the iQ Controller.
3.3 Touch Thermostat
The Touch Thermostat is the interface between the User or Installer and the Zoning System.
The Installer will set the Zone Control Module parameters through the thermostat. Those
parameters will be saved in the Zone Control Module during a power loss. As for the user, the
thermostat will be used to set the zone temperature set point, local ventilation mode, Sleep
mode and the time schedule setup.
The Touch Thermostat will allow the user to access any other zone and set the set point
temperature, without the need to go to the zone to make the change.
When the environmental conditions in a given zone do not allow the installation of a Touch
Thermostat (such as a bathroom), a Remote Temperature Sensor must be used. A thermostat
is still required for the zone. In these cases, the Sensor is placed in the space where the
temperature needs to be controlled. The thermostat will provide the same user interface
functions for the zone.
