Configure the system
The thermostat configuration will be done on
your online account. Here you can configure the
parameters of the system, such as: Heat Pump
or Normal, number of heat and cool stages,
heating fuel, calibration temperature, and
configurable terminal (Z). In your online
account, you will have to enter the thermostat
configuration. Refer to page 7 for the
appropriate diagrams when you set up
the thermostat.
While the default settings online will be
sufficient in most cases, you also have the
option to change advanced configuration
settings, such as: Swing, Differential, Recovery
Setting, Fan Circulation Period, Fan Circulation
Duty Cycle, Maximum Setpoints, Minimum
Setpoints, and Thermostat Lock.
CAUTION: Be careful when changing advanced
configuration settings. These configuration
settings should only be changed by those
familiar with heating and cooling systems’
parameters. Contact a local HVAC
professional for help.
