Only shown if ISU172 = 2 and ISU176 = 1 or greater.
Only shown if ISU172 = 2 and ISU200 = 1.
Only shown if ISU174 = 2.
Only shown if ISU172 = 2 and ISU176 = 1 or higher.
Default varies based on types of heating.
Only shown if ISU176 = 2 or for Heat Pump systems
with 2 stages of Auxiliary Heat.
Default varies based on types of heating.
Only shown if ISU176 = 3.
Default varies based on types of heating.
If backlight is on continuously, it is low-intensity. Light
changes to full brightness after pressing any key.
Auto Changeover allows user to choose heat, cool, off
or auto. When set to Auto the thermostat will
automatically choose heat or cool based on room
temperature and heat/cool set points. Manual
changeover allows the user to manually toggle
between heat, cool and off.
Only shown if ISU300 = 0. The deadband indicates the
minimum number of degrees that are allowed between
the heat and cool settings when in auto changeover.
For example, if the deadband is set to 3°F and the cool
setpoint is 75°F the warmest heat setpoint allowed
would be 72°F.
Set to 0 in areas that do not follow daylight savings
time.
Indoor temperature sensors will display the
temperature at the sensor location or an average of
two indoor temperature sensors, not including the
temperature sensor in the thermostat. The
temperature sensor in the thermostat is disabled when
using remote indoor temperature sensor(s).
An outdoor temperature sensor is required for heat
pump compressor lockout (ISU350), heat pump
auxiliary lockout (ISU360), dual fuel heat pump
balance point (ISU360) and Humidification with Frost
Protection (ISU372).
