THERMOSTAT TYPE SETUP

On Heat Pump equipment ONLY, either Gas/Electric or Heat Pump thermostats can
be used. The SmartZone controller MUST be set for the thermostat type being
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

THERMOSTAT WIRING

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
common connection or are battery powered / mechanical.
