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 system 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 information 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 30 (open / shorted condition). Since wired sensors are physically connected to a zone, Link will only provide an option to assign the sensor to the zone its connected to (or unassign the sensor if needed).
  • Page 31 Enable or disable temperature and humidity for each sensor as desired. Link will allow up to four sensors to be averaged within each zone. The system controller (SC360) can also be used as a zone sensor ONLY if it’s installed within the zone that is being controlled.
  • Page 32 If a zone only has one wireless sensor assigned and the wireless sensor fails (batteries are weak), then Link will enter single zone mode. All dampers will open, and Link will control temperature based on zone priority and zone size. In this example, if the wireless sensor fails, zone 1 still has three sensors to control temperature and comfort.
