Zoning Alarms and Alerts
Which Alarm do you have?
Please Note: M1 Mid Tier Inverter products are limited to two zones.
Zoning Alarms
Alarms begin with an A, and are in red buttons
Alerts begin with a T, and are in yellow buttons
When looking at fault codes, especially at the EcoNet thermostat, pay close attention to the verbiage and the suffix at the end. Don't allow yourself to be chasing a rabbit down the wrong hole by looking at a fault that may be in the indoor equipment and just using the numbers. Anytime you report a fault to your distributor, provide the complete fault description, not just the number.
_O means Outdoor Unit
_A means Air Handler
_F means Furnace
_C means Communication
_S means System
_Z means Zoning
Zoning related alarms can only be read on the
(-)ETST700SYS Smart Thermostat.
