If Manual staging is selected instead of Automatic, then 5 additional staging options for the Auxiliary heat need to be configured. Unlike straight
cooling projects where Manual Staging is recommended be enabled so Reverse Staging could be utilized, the same recommendation is not made for
heat pumps. The Auxiliary Staging adds an extra layer of complexity into the mix, especially if there are 2 compression stages plus 2 auxiliary stages,
so Automatic Staging should be selected on heat pump applications.
Installation Settings > Thresholds > Thermal Protect
A200485
The Thermal Protect range tells the thermostat the maximum difference allowed between the thermostat and hottest or coldest rooms in the home. If a
sensor measures a temperature that is significantly outside of this range, it probably means the reading is inaccurate. The thermostat will ignore this
inaccurate reading to prevent the heating or cooling from running excessively. This setting is adjustable from 10 to 25 degrees.
Installation Settings > Thresholds > Installer Code
A200486
It is recommended that professionally installed thermostats be locked out by enabling the Installer Code. This prevents the homeowner from
accidentally changing any of the settings in the Equipment, Thresholds, or Test Equipment settings. This lockout feature is separate from the Access
Control lockout and password that the homeowner can set for the homeowner settings.
Write this code down as it is not well documented or easy to find online. The code cannot be changed, as is the same for all thermostats.
