used or the equipment will not operate properly with potential risk of damage.
Set the thermostat type as shown below using the “STAT TYPE” and “Arrow” buttons.
NOTE: When GAS/ELECTRIC Equipment, this option is NOT available, all thermostats
will be GAS/ELECTRIC.
NOTE 2: When using SmartLink for 8X system, secondary controller stat type must
also be set using the same method.

SmartZone will use time and temperature to automatically manage staging.
This accurate method of staging eliminates the need for multi-stage
thermostats. SmartZone is compatible with most all thermostats that have a
