INTELLIZONE2 INSTALLATION MANUAL
It should be noted that the MasterStat Z2TK
troubleshooting harness can be useful during startup
by allowing the temporary connection of the MasterStat
directly at the IntelliZone2 relay board for ease of
configuration or servicing.
Before powering the unit, check the following:
•
Fuses, breakers and wire size are correct.
•
Low voltage wiring has been completed.
•
MasterStat has been configured correctly.
•
Thermostats are wired and DIP switches are set for
proper zone #.
•
Blower speed has been set on the AID Tool.
•
Aurora control is configured for IntelliZone2.
